BIN2 phosphorylation of SYP22 is required for stomatal opening and vacuolar fusion in guard cells of Arabidopsis.

#Phosphorylation-mediated regulation of the stability of SYP22 by BIN2 modulates #vacuolar #fusion in guard cells and affects #stomatal #opening.

In HR, using CRISPR/Cas9 gene editing and overexpression techniques, the researchers demonstrated that manipulating SlVI alters sugar accumulation, strengthens fruit firmness, and boosts resistance to fungal pathogens.

🙏🏻 for the highlight @frenchdcsociety.bsky.social one important finding was the very efficient #vacuolar pathway in MZ #macrophages challenging the current view that #proteasome dependent pathways (active in DC1) are prominent to generate antigenic peptides for #MHC-I through #cross-presentation
