Understanding plant breathing: Identification of the key protein interplay behind rhythmic stomatal movements 

Researchers discovered the interaction between proteins PIF and KAT1, essential for stomatal rhythmic movements in plants. This mechanism controls stomata opening in the day and closing at night, vital for photosynthesis and water regulation. This knowledge aids in enhancing crop…

Image credit: Nitrogen nutrition and signaling during root nodule symbiosis impact the community assemblies. Lotus plants grown in the presence of inorganic nitrogen secrete specific metabolites and assemble a microbial community with low connectivity. Lotus plants grown in symbiosis-permissive conditions secrete metabolites such as flavonoids (1) that induce Nod factor production in compatible nitrogen-fixing Rhizobiumisolates (2). Nod factors are recognized by the Lotus host which initiates a signaling pathway (3) to accommodate the symbiont. Symbiotically active roots have an exudate profile (4) and associated microbial communities that differ from plants grown in the presence of inorganic nitrogen. It remains to be determined how bacterial communities associated with symbiotically active plants impact the host to promote the symbiotic association and plant growth (5).

Scientists discover primary wound signal that promotes plant regeneration

Scientists identified REGENERATION FACTOR1 (REF1) as the primary wound signal that initiates plant regeneration. REF1 binds its receptor PORK1 to activate SlWIND1, promoting cellular reprogramming and tissue repair. This breakthrough enhances crop transformation efficiency, offering a universal solution for improving…
