Message from Department Chair

Dear PLPM Family,

The fall semester is in the books and with it, the 2018 calendar year is coming to a close. What a year it has been – a lot of excitement and very big changes! The most obvious one is the fact that I am writing this from my beautiful new office in our beautiful new ATRB home.

We have a lot to be thankful for, but I particularly want to express my thanks again to all of you who made this year possible and spent countless hours and overcame many obstacles to get all of us into our new home. Please, take pride in this accomplishment and cherish our moment of coming together and of succeeding. We truly were one big PLPM family then. Thank you!

I am sure most of you have heard by now, but I mention again that this next year will be my last as your chairperson – I am in my 14th year and I earlier had informed Interim Dean Colletti that it is time for a change. Soon after Dean Robison will take office in January 2019, he will initiate the proceedings to identify a new department chair for all of us. Let us pull together again to make this happen as smoothly as possible!

Sincerely,Thomas Baum

The PLPM department honors Dr. Engelhard by naming the office suite after him for his generous donation towards the department

Dr. Arthur Engelhard earned his bachelor’s from Ohio, his master’s from Yale, and his PhD from ISU in 1955. His dissertation was titled, “Host-parasite relation-ships of Endoconidiophora Fagacearum Bretz, the cause of oak wilt.” Dr. Engelhard also worked with foliage fungicide of chrysanthemum and with geranium rust in green-house environments. He retired from the University of Florida many years ago and he now lives in Bradenton, FL. Dr. Engelhard attended the Presidential Instal-lation Ceremony of Dr. Wintersteen followed by a lun-cheon with PLPM graduate students. During the lun-cheon, Dr. Engelhard shared his career journey and provided good advice to graduate students. In the af-ternoon, the PLPM held a reception for Dr. Engelhard where faculty, students, and staff had the opportuni-ty to thank him for his generous donation towards the Advance Teaching and Research (ATRB) building fund. The department honored Dr. Engelhard’s dona-tion by naming the PLPM suite “Dr. Arthur W. Engel-hard Plant Pathology and Microbiology Suite”.

Installation of the new ATRB mural

The installation of the new mural in the Iowa State Uni-versity Advanced Teaching and Research Building (ATRB) oc-curred on Wednesday, October 31, 2018. The reception began with comments from President Wendy Wintersteen about the research that takes place in ATRB and the magnificent pieces of work that Artist Rose Frantzen has done. Following President Wendy Wintersteen welcoming speech, Iowa artist Rose Frant-zen guided the audience through her meticulous process while creating the mural, which she titled “Rhythms-Bean Fields at Sun-set”. This mural was commission by the College of Agriculture and Life Sciences and it celebrates the beauty of Iowa’s growing season and importance of soybean research and crops in our agricultural industry. Rose Frantzen is a native of Maquoketa, Iowa. She has gained national and international acclaim for her oil paintings from life that bring contemporary perspective to a traditional approach. Rose has created wonderful oil painting pieces from landscapes, still life, figurative works, and amazing portraits. Her latest piece “Rhythms-Bean Fields at Sunset” gives the im-pression of wind blowing along fields of soybeans. It is a won-derful yet calming piece that is now located in the ATRB Iowa Soybean Association Lobby. We invite you to stop by the ATRB Iowa Soybean Association Lobby located in the east entrance of the building to appreciate this beautiful mural by Frantzen.

Installation of the new art piece in the ATRB Atrium

It was early December with temperatures in the upper 20s when the community of researchers, faculty, students and staff in the Advanced Teaching and Research Building (ATRB) began to observe the arrival of large pieces of fiberglass rods outside the east entrance of the building. During the first week of Decem-ber, Artist Gaston Nogues and his assistants carefully assembled the piece of art that now hangs over the ATRB atrium. It was a unique experience for the ATRB community to see the piece of art come to life. During a casual conversation with the artist on the Friday Evening of December 6, 2018, it was mentioned that the inspiration for this piece was growth or he imagined that this piece grows in a way a plant will grow or something else biolog-ical. However, the artist wanted individuals to create their own interpretation of his work, so throwing some ideas around, we came up with: nematodes, a plant budding, or the germination of a seed coming out of the wall, among others. The artwork assembly was finished on Monday, Decem-ber 10, 2018. After serious consideration, artists Benjamin Ball and Gaston Nogues named their piece of artwork “Organic Dream Synthetic Means”. The artwork can be admired from the ground level of the ATRB atrium and through the glass views from the second and third floor. We invite you to admire the artwork “Organic Dream Synthetic Means” from all the different perspectives and create your own interpretation. What do you see that is biological in origins? To learn more about the meaning of the art, please check the interview with the artist here.

News from the PLPM GSO

In late 2018 summer, a graduate student representative from the University of Wiscon-sin-Madison contacted the department chair, Dr. Thomas Baum, looking to collaborate with the Plant Pathology and Microbiology Department of Iowa State University (ISU). The collaboration was regarding a graduate student seminar exchange program where graduate students have the opportunity to visit peer departments to present their research. Dr. Baum thought it would be a great opportunity for the Plant Pathology departments of both universities to collaborate in this intriguing project, so he passed this information to the current serving president of the Plant Pathol-ogy and Microbiology Graduate Student Organization (PLPM-GSO), Elizabeth Carino. Elizabeth believed this was a great opportunity for PLPM graduate students to expand their network and a great platform to enhance communication skills. She gathered extensive information from the representatives of the University of Wisconsin-Madison so she could present the idea with the PLPM-GSO executive board (Julie Aiza Mandap and Gabriela Morel). During this “Graduate Student Seminar Exchange Program”, graduate students from both universities would have the opportunity to visit and present their research to peer departments and land-grand institutions. To make this happen, the hosting institution would have to cover the cost of lodging and food while the other institution covers the travel expenses of their students. The ISU PLPM-GSO quickly real-ized that they would need monetary help to cover these expenses. So they set-up a crowdfunding platform through the ISU foundation to raise the funds needed to kick-off this project. The PLPM-GSO was able to fundraise $1,180 through FundISU program. Thanks to the gen-erous donations of faculty, alumni, students and their families that they were able to fundraise enough to start this great project. The PLPM-GSO would like to thank to everyone who made this possible. The project is most likely to launch in Fall 2019.

News from the PLPM GSO

Farewell 2018 PLPM GSO,Welcome the 2019 PLPM-GSO

It is the end of the semester which means that the reign of the current PLPM-GSO (Pres-ident: Elizabeth Carino, Vice-President: Julie Aiza Mandap, and Treasurer: Gabriela Morel-Ga-dea) has ended. Towards the end of the semester PLPM graduate students nominated their peers to run for each position of the PLPM-GSO executive board. It was an uphill battle to find enough candidates as several of the senior students had previously served on the PLPM-GSO and wanted to give the opportunity to fresh faces to take the lead. However, three courageous graduate stu-dents accepted this challenge and were elected the 2019 PLPM-GSO. We would like to welcome President elect Zach Lozier, Vice-President elect Aline Sartor, and Treasurer elect Elizabeth (EB) Wlezien.

Although it is very exciting to see what the new PLPM-GSO will do, let us not forget the great job that the 2018 PLPM-GSO did. These three women, President Elizabeth (Liz) Carino, Vice-President Julie Aiza Mandap, and Treasurer Gabriela (Gavy) Morel-Gadea worked hard to keep the annual PLPM traditions running and bring back old ones. Liz, Aiza, and Gavy had great ideas in mind when they took over the PLPM-GSO. However, those ideas required more funds than what they had available so they kicked-off their reign by organizing a PLPM Polo shirt fundraiser in the spring semester of 2018. Since the majority of the PLMP department had moved to the new Advanced Teaching and Research Building (ATRB), they decided to organize a “free Summer Breakfast kick-off” where they brought food for everyone to enjoy. However, this event was designed to be a teaser to promote a departmental “Canoe Race + BBQ”. For years, graduate students listened to stories about the legendary PLPM canoe races during the Fall re-treat, but due to many rainy days in previous years the previous PLPM-GSO had given up on this idea. Liz, Aiza, and Gavy were able to bring this tradition back in 2018 which all participants enjoyed. Therefore, we would like to recognize Liz Carino, Aiza Mandap, and Gavy Morel-Ga-dea for all their great work, the three left a tough act for the successors to follow. Nonetheless, we look forward to see what the new 2019 PLPM-GSO will do.

Apple recipesApple Churros

By Elizabeth CarinoINGREDIENTS:• 2 apples• 1 lemon• 4 eggs• 2 teaspoons of sugar• ½ teaspoon of salt• ¼ cup of butter• ¼ tsp cinnamon• 2 tablespoons of brown sugar• 1 cup of water• 1 cup of all-purpose flour• Vegetable oil

DIRECTIONS:1. Peel the apples and place them on a container containing lemon water. Leave apples in the lemon

water for 2-5 minutes. Note: Squeeze the lemon juice in a bowl/container. Then place the peeled apples in the lemon water container. Make sure that the water covers the peeled apples.

2. Shred the apples and place them in a bowl along with 2 teaspoons of sugar, ¼ teaspoon of cinna-mon. Mix well and leave apples to marinate.

3. In a saucepan, add 1 cup of water, ¼ cup of butter, 2 tablespoons of brown sugar, ½ teaspoon of kosher salt, 1 cup of water. Heat up until it starts to boil. Then, add 1 cup of flour and stir until the mix is homogenous. Remove from the heat and add the eggs one at the time until all 4 have been incorporated into the mixture.

4. Drain the liquid from the apple mix (step 2). Add the drained shredded apple to the dough (step 3) and mix well. Transfer apple churro dough into a pipetting bag with a wide star tip.

5. Heat up the vegetable oil in a saucepan. When the oil has reached the appropriate temperature, start pipetting strips of apple churro dough into the frying oil (to the length desired).

Note: To know if the oil has reached the correct temperature, you can roll a tiny amount of dough and place it on the oil. If the dough rises (floats) then the oil is ready. You will also observe small bubbles coming out of the dough when oil is ready.

6. Once the churros reach a golden color, remove from the oil. Drain the excess of oil in a container or plate with paper towels.

7. In another container, prepare a sugar and powder cinnamon mix (the amount of cinnamon could vary based on taste).

8. Once the churros have drain and cool down to touch, roll them in the cinnamon sugar mix. They are ready to eat. Enjoy.

Apple Cheesecake ChurrosBy Maxwell McReynolds

INGREDIENTS:For the churro bowls• Cooking spray• 2 oz. (12-oz.) packages puff pastry, thawed• 1/2 c. cinnamon sugar• For the cheesecake filling• 16 ounces plain full-fat cream cheese (two 8-ounce packages; 455g)• 3/4 cup (150g) granulated sugar• 1 tablespoon (20g) fresh juice from 1 lemon• 1 teaspoon vanilla extract• 1/8 teaspoon kosher salt• 1 1/2 cups (357g, 12 ounces) heavy whipping cream

For the apple filling2 tbsp. butter4 apples, peeled, cored, and chopped1/4 c. granulated sugar1/4 c. lightly packed brown sugarJuice of 1/2 lemon1 tsp. ground cinnamonPinch kosher salt

DIRECTIONS:1. Preheat oven to 400°F and sprayed and an inverted muffin tin with cooking spray. Roll out puff

pastry and using a 4” cookie cutter cut out 12 circles. Place puff pastry on inverted muffin tin and press to form bowls. Bake until Golden, 10 to 12 minutes. Allow it to cool. Because you are working with puff pastry, you might have to use an oven mitt and gently press bowls back onto muffin tin and reshape bowls.

2. When puff pastry has cool down enough to handle, remove bowls from muffin tin and toss in cinnamon sugar.

3. Combine the cream cheese, sugar lemon, vanilla, and salt in a bowl of a stand mixer fitted with a paddle attachment. Mix at medium speed until soft and smooth. Scrape the bowl as needed.

4. Switch to the whisk attachment and pour in the cream. Mix at low speed to combine, then in-crease to high and whip until the mixture can hold stiff peaks, approximately 3 to 5 minutes.

5. Pour into the prepared, cool churro crust until half full. 6. Refrigerate until the filling is firm and cold, about 6 hours or overnight. 7. After filling is firm, make apple pie filling. In a medium sauce pan over medium heat, melt but-

ter. Add the apples, sugar, lemon juice, cinnamon, in a pinch of salt. Cook while stirring occa-sionally until apples are soft and caramelized, about 20 minutes. Let it cool for about 10 minutes.

8. Fill the churro bowls with apple pie filling and drizzle with caramel, whipped cream, chocolate, or other topping. Your apple cheesecake churros are now ready to eat. Enjoy.
