Zhu, Y., Klasfeld, S., & Wagner, D. (2021). Molecular regulation of plant developmental transitions and plant architecture via PEPB family proteins–an update on mechanism of action. Journal of Experimental Botany, eraa598
This year marks the 100 th anniversary of the experiments by Garner and Allard (Garner and Allard, 1920) that showed that plants measure the duration of the night and day (the photoperiod) to time flowering. This discovery led to the identification of Flowering Locus T (FT) in Arabidopsis and Heading Date 3a (Hd3a) in rice as a mobile signal that promotes flowering in tissues distal to the site of cue perception. FT/Hd3a belong to the family of phosphatidylethanolamine binding proteins (PEBPs). Collectively, these proteins control plant developmental transitions and plant architecture. Several excellent recent reviews have focused on the roles of PEBP proteins in diverse plant species; here we will primarily highlight recent advances that enhance our understanding of the mechanism of action of PEBP proteins and discuss critical open questions.

In the mist of the USA elections, the Wagner Lab is over joyed to welcome Dr. Shalini Yadav. Dr. Yadav traveled all the way from the Indian Institute of Science Education and Research (IISER) in Mohali, India where she received her Ph.D. In the Wagner Lab she plans to study the role of antiflorigen Terminal Flower (TFL1) in axillary meristem fate.
We are so excited for our newest publication in the lab as well as a Penn Today‘s profile of the work!
Welcome Tian Huang! Tian did his undergraduate studies in Fudan University, in Shanghai, China and now he is sharing his enthusiasm for plant research as a member of the Biology Graduate Program. We are so excited that he chose to join our lab and look forward to the discoveries we will make together.
Communication in science is of utmost importance for scientific advancement. Science Advances is an online-only gold open access journal from American Association for the Advancement of Science (AAAS), the publisher of Science. Debuty Editor, Dr. Elizabeth Haswell, is heading up a brand new editorial pod dedicated to plant biology and she chose fantastic editors including Dr. Doris Wagner of the Wagner Lab. Others on the team include Dr. John McDowell, Dr. Mary Lou Guerinot, Dr. Thorsten Hamann, Dr. Keiko Sugimoto, Dr. Elizabeth Kellogg, and Dr. Sarah O’Connor.
The University of Pennsylvania Biomedical Research Academy is a summer program that introduces the experimental basis of cellular, molecular, and genetic aspects of biology to students in 9th-11th grade. Dr. Doris Wagner gave a virtual live lecture to help student gain insight into our research on drought stress and epigenetics in plants.
Congratulations to Dr. Run Jin for successfully defending her PhD Thesis! We are so proud of her and will miss her in the lab.
All are invited to the thesis research defense of Wagner Lab’s Run Jin.
