Posttranslational regulation of photosynthetic activity via the TOR kinase in plants
Plant Science Research WeeklyIn the dazzling dance of plant cellular life, chloroplasts must groove in harmony with growth to sidestep the perils of photooxidative damage. This harmony between photosynthesis and photooxidative damage is orchestrated by the guanosine tetraphosphate (ppGpp) signalling pathway which traces its roots…
The main oxidative inactivation pathway of the plant hormone auxin (Nature Comms.)
Plant Science Research WeeklyAuxin is a key hormone in almost all stages of the plant development and its main natural form is indole-3-acetic acid (IAA). In Arabidopsis, several gene families are involved in auxin homeostasis. In this work, Hayashi et al. focus on the roles of DIOXYGENASE FOR AUXIN OXIDATION 1 (DAO1) which converts…
