Cell wall remodeling is important for plants to adapt to environmental stress. Under salt stress, cortical microtubules undergo a depolymerization-reassembly process to promote the biosynthesis of stress-adaptive cellulose, but the regulatory mechanisms underlying this process are still largely unknown. In this study, we reveal that FERONIA (FER), a potential cell wall sensor, interacts with COMPANION OF CELLULOSE SYNTHASE1 (CC1) and its closest homolog, CC2, two proteins that are required for cortical microtubule reassembly under salt stress.

Intriguingly, P1 is the most divergent among all mature viral factors, and its roles during viral infection are still far from understood. In this study, we found that telosma mosaic virus (TelMV, genus ) in passion fruit, unlike TelMV isolates present in other hosts, has two stretches at the P1 N terminus, named N1 and N2, with N1 harboring a Zn finger motif.

Protochlorophyllide oxidoreductase (POR) plays a key role in catalyzing the light-dependent reduction of protochlorophyllide (Pchlide) to chlorophyllide (Chlide), and thus promotes the transit from etiolated seedlings to green plants. In this study, by exploring ethyl methanesulfonate (EMS)-mediated mutagenesis in NL-6 variety, we identified a mutant that displays faded green leaf and reduced chlorophyll (Chl) and carotenoid contents. Bulk segregant analysis (BSA) revealed that a mutation in gene is genetically associated with the faded green leaf of the mutant.

Its positive-sense single-stranded RNA genome is comprised of 9,437 nucleotides (nt), excluding the poly (A) tail, and contains one large open reading frame encoding a polyprotein of 3,019 amino acids (aa).
