ROS homeostasis mediated by MPK4 and SUMM2 determines synergid cell death (Nature Comms)

Female gametophytes (FG) of angiosperms contain eight nuclei and seven cells, distributed in a defined manner. In the micropylar end of the FG there are two synergid cells and the haploid egg, while in the central cell there are two polar nuclei. The synergid cells are responsible for attracting the…

Reactive oxygen species homeostasis in rose petals

Zhang et al. show that a transcription factor module modulates TCA cycle strength and thus reactive oxygen species homeostasis in rose petals. Plant Cell. https://doi.org/10.1093/plcell/koab152  Background: Reactive oxygen species (ROS) are by-products of several primary metabolic pathways and high…
