Mitogen-activated protein kinase (MAPK) cascades are involved in host defense against pathogens and often activated by upstream plasma membrane leucine-rich repeat receptor-like kinases (LRR-RLKs). ERECTA (ER) is an LRR-RLK that regulates plant developmental processes through activating MAPK cascades. Tomato leaf curl Yunnan virus (TLCYnV) C4 interacts with BKI1, stabilizes it at the impairs ER...

Abstract Background Abscission is an active, organized, and highly coordinated cell separation process enabling the detachment of aerial organs through modification cell-to-cell adhesion breakdown walls at specific sites on plant body known as abscission zones. In Arabidopsis thaliana , floral cauline leaves regulated by interaction hormonal peptide INFLORESCENCE DEFICIENT IN ABSCISSION (IDA), ...

Plant immune recognition of pests and pathogens relies on a germline-encoded repertoire innate receptors. In recent years, many examples cell surface receptors in the large gene family receptor-like proteins (RLPs) have been shown to govern specificity. RLPs lack canonical intracellular kinase domain associated with receptor kinases, but instead transduce signaling through interactions co-recep...

An open question remains as to what coordinates cell behavior during organogenesis, permitting organs to reach their appropriate size and shape. The Arabidopsis gene STRUBBELIG (SUB) defines a receptor-mediated signaling pathway in plants. SUB encodes a putative leucine-rich repeat transmembrane receptor-like kinase. The mutant sub phenotype suggests that SUB affects the formation and shape of ...

Abstract Upon viral infections, RIG-I-like receptors (RLRs) sense cytosolic RNAs and initiate signaling pathways culminating in the activation of IRF3 subsequent type I interferon (IFN) antiviral response. This intrinsic protective mechanism is orchestrated by a host positive negative regulators, which collectively govern magnitude duration signaling. SRMS an understudied non-receptor tyrosine ...
