September 6, 2024 - Rewards of Diving Deep

Dear Danforth Center Community,

Diving deep into a scientific problem always results in surprising discoveries, detailed mechanistic understanding, new and important research directions, or unexpected applications that address real needs. Let’s highlight and briefly explain three recent publications, and recognize three Danforth Center teams that have persisted in understanding three different areas of plant science.

Transposase-assisted target-site integration for efficient plant genome engineering.
Liu P, Panda K, Edwards SA, Swanson R, Yi H, Pandesha P, Hung YH, Klaas G, Ye X, Collins MV, Renken KN, Gilbertson LA, Veena V, Hancock CN, Slotkin RK. Nature. (2024) doi: 10.1038/s41586-024-07613-8. The Slotkin team has made numerous, insightful discoveries about how plant transposons, which can jump from place to place in a genome, are either locked in place or enabled to jump. From that deep understanding, the team developed ways to harness the unique attributes of certain transposons to insert new DNA into specific, desired sites in the genome. This opens up vast possibilities to accelerate crop improvement in ways that increase precision and lower costs. You have not heard the last about this new technology!

SymRK regulates G-protein signaling during nodulation in soybean (Glycine max) by modifying RGS phosphorylation and activity.
Choudhury SR and Pandey S. Molec. Plant Microbe Interact. (2024) doi: 10.1094/MPMI-04-24-0036-R. The Pandey lab has focused intensely on how plants respond to changes in their environment, like when certain symbiotic bacteria interact with roots. Legumes like soybean interact with specific beneficial bacteria (e.g. rhizobia), resulting in nodules that churn out a natural form of fertilizer for the plant. The team here revealed several new, critical molecular interactions involving G-proteins and receptors that enable plants to engage with the bacteria.

pyMS-Vis, an open-source Python application for visualizing and investigating deconvoluted to-down mass spectrometric experiments: A histone proteoform case study.
Pesavento JJ, Bindra MS, Das U, Rommelfanger SR, Zhou M, Paša-Tolić L, Umen JG. Analytical Chem. (2024) doi: 10.1021/acs.analchem.4c02650.  The Umen team is well known for longstanding, elegant research to understand how algal cells multiply and differentiate into sexually distinct types. This paper revealed not only new insights into how algal genomes are controlled during the cell cycle, but also an entirely new method that any other team can use to measure and compare different forms of proteins and protein complexes.

I admire the persistence and commitment needed to solve hard scientific problems. And I sincerely appreciate when that effort yields important insight and application beyond what was initially envisioned!

Jim Carrington,
President and Chief Executive Officer

Danforth Center Response Plan

The Danforth Plant Science Center recognizes the potential of exposure to Coronavirus (COVID-19) in our building and the impact it could have on our people and the Center. Accordingly, we have a plan in place in the event of a positive test for COVID-19 of an individual who was present in our Building(s).

Danforth Center Updates

During this unique moment in history, the first priority of the Donald Danforth Plant Science Center is the health and safety of our Center community, our families, and those who work with us.
