Exposure to cold triggers a spike in cytosolic calcium (Ca 2+ ) that often leads transcriptional reprogramming plants. However, how this Ca signal is perceived and relayed the downstream signaling pathway remains unknown. Here, we show CALCIUM-DEPENDENT PROTEIN KINASE 28 (CPK28) initiates phosphorylation cascade specify of cold-induced signal. Plasma membrane (PM)–localized CPK28 activated rapidly upon shock within 10 seconds -dependent manner. then phosphorylates promotes nuclear...
Abstract Plants respond to cold stress at multiple levels, including increasing cytosolic calcium (Ca2+) influx and triggering the expression of cold-responsive genes. In this study, we show that Ca2+-permeable channel CYCLIC NUCLEOTIDE–GATED CHANNEL20 (CNGC20) positively regulates freezing tolerance in Arabidopsis (Arabidopsis thaliana) by mediating cold-induced Ca2+ influx. Moreover, demonstrate leucine-rich repeat receptor-like kinase PLANT PEPTIDE CONTAINING SULFATED TYROSINE1 RECEPTOR...
Ubiquitination modulates protein turnover or activity depending on the number and location of attached ubiquitin (Ub) moieties. Proteins marked by a lysine 48 (K48)-linked polyubiquitin chain are usually targeted to 26S proteasome for degradation; however, other chains, such as those K63, regulate properties. Here, we show that 2 PLANT U-BOX E3 ligases, PUB25 PUB26, facilitate both K48- K63-linked ubiquitination transcriptional regulator INDUCER OF C-REPEAT BINDING FACTOR (CBF) EXPRESSION1...
Summary The endoplasmic reticulum‐associated degradation (ERAD) system eliminates misfolded and short‐lived proteins to maintain physiological homeostasis in the cell. We have previously reported that ERAD is involved salt tolerance Arabidopsis . Given central role of phytohormone abscisic acid (ABA) plant stress responses, we sought identify potential intersections between ABA pathways response. By screening for response a wide array mutants, isolated gain‐of‐function mutant, doa10a‐1 ,...
Activating and constraining calcium (Ca2+) signals are crucial for cellular responses to abiotic stress such as cold stress. Upon exposure cold, plants generate Ca2+ signal with a specific peak time, amplitude, frequency via channels or transporters, but the regulatory mechanism remains poorly understood. Here, we report that CYCLIC NUCLEOTIDE-GATED CHANNEL 5 (CNGC5) CNGC6 confer cold-induced in Arabidopsis (Arabidopsis thaliana) their activities precisely regulated by protein kinase...
