TTL bridges microtubules and cellulose synthase complexes

/in /by

Cellulose synthase (CESA) complexes (CSCs) synthesize the main polysaccharide component of plant primary cell wall, cellulose. The trafficking and dynamics of CSC are tightly regulated. Kesten et al. identified a new family of CSC- and microtubule-interacting proteins, named TETRATRICOPEPTIDE THIOREDOXIN-LIKE (TTL) proteins, which help to maintain cellulose synthesis under salt stress. The ttl1 ttl3 double […]

TOR complex regulates actin cytoskeleton dynamics through controlling ATP levels (PNAS)

/in /by

TOR (Target of Rapamycin) complex is an information hub that integrates nutrition and energy signals and serves as a master regulator for multiple downstream cellular processes. The actin cytoskeleton in plant cells is highly dynamic, with rapid changes of its organization and constant turnover between its monomeric and filamentous forms, requiring a large energy supply. […]
