Women in plant science around the world The article series ‘Women in plant science around the world’ marks the 30th anniversary of Trends in Plant Science, a milestone that invites us to reflect on three decades of shared discoveries, international collaborations, and the diverse voices that propel the field forward. By centring 30 of our women authors from 30 countries, we honour the global community that continues to advance plant science, and we hope to inspire the next generation of women researchers, as well as researchers from other still underrepresented groups in plant science.

A synthetic ERFVII-dependent circuit in yeast sheds light on the regulation of early hypoxic responses of plants | PNAS Plants face hypoxic conditions either chronically, as particular tissues are characterized by fluctuating or stable low oxygen levels, or acutely, ...

Finally officially out!!

“My wish is that this will provide a positive message to the young girls who would like to follow the path of science and to show them that women in science can also have an impact through their research.”

Fig. 1 (shortened, full legend in paper): Regulation of TOR function by chloroplast-derived metabolites. (A) Photosynthetically derived sugars exported from the chloroplast activate TOR (via phosphorylation, P) in distal plant tissues. Sugar regulation of TOR can occur via SnRK1, or potentially via other routes (dashed arrow). Notably, TOR activation by sugar in roots requires mitochondrial function. (B) DHAP, a triose phosphate product of photosynthesis, positively regulates TOR in the green alga Chlamydomonas. (C) Active TOR directly phosphorylates the ABA receptor PYL, thereby inhibiting it. ABA, whose precursors are made in the chloroplast, binds PYL. ABA-bound PYL binds and inhibits the PP2C phosphatase, activating SNRK2. Active SNRK2 directly phosphorylates the RAPTOR subunit of TOR, inhibiting TOR activity.
