Intertwined signatures of desiccation and drought tolerance in grasses April 30, 2020 Intertwined signatures of desiccation and drought tolerance in grasses

In a new study published in PNAS, PRI scientists led by Horticulture-Plant Resilience Institute faculty member Robert VanBuren show that some grasses can survive typically lethal drought events through entering a dormant, desiccated state until the return of water. In the study, the team aimed to find what distinguishes this unique desiccation tolerance response from conserved drought responses observed in all grasses. They identified genomic and expression changes distinguishing the desiccation-tolerant grass Eragrostis nindensis from its sensitive crop relative Eragrostis tef and then expanded these analyses to include several cereals to identify broadly conserved and divergent patterns during water-deficit stress. They found that the distinction between drought and desiccation in grasses is subtle, where genes with essential roles in seed development are broadly expressed during water-deficit stress. They propose that many of the pathways enabling desiccation tolerance are of ancient origin with universal roles in water deficit, and are conserved across grasses.

MSU researcher receives grant to continue studying pathogen resistance in plants April 29, 2020 MSU researcher receives grant to continue studying pathogen resistance in plants

MSU plant pathologist Brad Day has received a nearly $1 million grant from the National Science Foundation to extend his study on how plants, at the cellular level, respond to disease threats.

A COMMON METABOLIC CURRENCY TUNES GROWTH-DEFENSE BALANCE IN PLANTS April 7, 2020 A COMMON METABOLIC CURRENCY TUNES GROWTH-DEFENSE BALANCE IN PLANTS

When plants defend against a threat, their growth slows to a crawl. In their efforts to understand why, the Howe lab is constantly pushing the limits: how high can one tune plant defenses before a plant goes belly up?
