Recruiting new members!!! 8.27.2019
We have TWO openings, one post-doc and one PhD student, in the lab of Tomo Kawashima at University of Kentucky to study molecular and cellular dynamics of endosperm development. The endosperm is a part of the seed and performs unique cellular processes such as nuclear divisions without cytokinesis and cellularization, providing us a great platform to investigate plant cellular dynamics as well as how endosperm development affects the final seed size. Successful candidates will use live-imaging, genetics, genomics, and biochemical approaches, to investigate (i) how plants control cytoskeleton dynamics in the multinuclear endosperm and (ii) how altered endosperm development affects subsequent seed development. The candidates will actively participate in collaborations within the US as well as with Japan to perform high-impact science through this project.
These positions are funded by NSF for 3 years, with a possible extension, contingent upon performance and funding and can start October 1st, 2019.
Qualifications for a PhD student position:
- B.S. in Science [If you already have a M.S. degree, M.S. degree credits (18 maximum) can be recognized toward PhD degree credits]
- The minimum TOEFL score is 550 (paper-based) 213 (computer-based), or 79 (internet-based), if ou are from a non-English spoken country
- GRE score is NOT required upon submission of your application
- Basic molecular biology knowledge and bench work experience
- Interest in plant molecular biology and reproduction
- Strong motivation and willingness to learn new techniques
Qualifications for a post doc position:
- PhD in molecular, cell, or developmental biology, biochemistry, or related disciplines (scientists who received a PhD within 2-3 years or fresh graduates are encouraged to apply)
- Experience in confocal microscopy, genomics (SNP identification/RNA-seq/ChIP-seq), and/or actin filament biochemical assays is preferable, but not required
- Ability to think critically and innovatively, and write manuscripts for publication
- Excellent interpersonal skills and the ability to work well independently and within a group
To apply, please send:
- A cover letter summarizing your research interests, career goals, potential start date, & your motivation to join the Kawashima Lab
- Contact information of three references
to Tomo Kawashima (firstname.lastname@example.org).

How new cell types evolve remains a major question in biology. Across multi-cellular organisms, reproduction generally occurs via small, motile sperm that fertilize large immotile eggs. However, the widely varied morphologies of sperm makes one wonder whether this cell type evolved from a single common ancestor or if sperm identity was defined by distinct events in separate group of organisms.
In work published today in Nature Communications, a collaborative project found that a single molecular event which occurred 700 million years ago was responsible for the evolution of sperm in all land plants.

TeKrony Graduate Travel Fellowship in Seed Biology
Our graduate students, Foteh and Fatema, have been selected for Tekrony Gradute Travel Fellowship in Seed Biology. Congratulations!
Dr. TeKrony was a faculty member of the Department of Plant and Soil Sciences for nearly 40 years. His research, primarily with corn and soybean, focused on techniques for the determination of seed vigor, the effect of the production environment on seed germination and vigor levels, and the relationship between seed germination and vigor levels and performance including seedling emergence in the field, yield and seed storability.
Congratulations to the winners of the First Annual 3-Minute-Thesis Competition, held Friday, February 16, 2018. Winners in the student competition are: Lucas Araujo, First Place; Rebecca McGrail, Second Place; Mohammad Alsabri, Third Place. In addition, audience members voted for their favorite speaker among student and faculty presentations. Lucas Araujo was chosen fan favorite among student speakers. Dr. Tomo Kawashima was fan favorite among the faculty speakers.
