Salicylic acid (SA) is a vital phytohormone produced from isochorismate in arabidopsis (Arabidopsis thaliana). However, SA in most plant species is produced from phenylalanine, a pathway that has long remained unresolved. Three recent studi...

Plants balance growth and defense via age-related resistance (ARR): juveniles prioritize growth, adults boost immunity. MicroRNA (miRNA)-transcription factor (TF) modules act as molecular switches, repressing defense pathways early and acti...
Sugar codes for plant fitness: arabinosylation in small peptide signaling [0.03%]

Arabinosylation, a critical post-translational modification (PTM) ubiquitous in plants, has received insufficient scientific attention relative to its biological significance. While small secreted peptides (SSPs) are crucial signaling molec...

The 'cry-for-help hypothesis' (CHH) is broadly used to study how root exudate modulation under stress influences recruitment of beneficial microbes in the rhizosphere. Here, we explored common misconceptions and limitations of the CHH and a...

Two recent studies (Huang et al. and Xiao et al.) reveal how EDS1-SAG101 facilitates NRG1A resistosome formation, triggering immunity. They also show truncated NRG1C as a negative regulator that sequesters EDS1-SAG101, preventing overactiva...

Photoinhibition of photosystem II (PSII) limits the fixation of light energy by photosynthesis and, thus, the productivity of plants everywhere. Photosynthetic organisms are equipped with a system that protects the photosynthetic machinery ...

Environmentally induced epigenetic changes have no hereditary stability in plants. Recently, Song et al. revealed a trade-off between rice's epigenome and cold adaptation, bridging the gap between environmental response and heritable epigen...

A recent study by Wang et al. demonstrates that nitric oxide (NO) influences plant development and stress tolerance in arabidopsis (Arabidopsis thaliana). By modulating mitogen-activated protein kinase 6 (MPK6) phosphorylation through NO-dr...

The stomatal aperture is finely tuned through guard cell reactive oxygen species (ROS) levels. Chang et al. recently elucidated the relationship between guard cell ROS homeostasis and stomatal behavior, revealing a molecular mechanism by wh...
