Protein kinases are major players in various signal transduction pathways. Understanding the molecular mechanisms behind plant responses to biotic and abiotic stresses has become critical for developing and breeding climate-resilient crops. In this review,we summarize recent progress on understanding plant drought, salt, and cold stress responses, with a focus on signal perception and transduction by different protein kinases, especially sucrose nonfermenting1(SNF1)-related protein kinases(Sn RKs),mitogen-activated protein kinase(MAPK) cascades,calcium-dependent protein kinases(CDPKs/CPKs),and receptor-like kinases(RLKs). We also discuss future challenges in these research fields. 展开更多

Stomata, the pores formed by a pair of guard cells, are the main gateways for water transpiration and photosynthetic CO2 exchange, as well as pathogen invasion in land plants. Guard cell movement is regulated by a combination of environmental factors, including water status, light, CO2 levels and pathogen attack, as well as endogenous signals, such as abscisic acid and apoplastic reactive oxygen species (ROS). Under abiotic and biotic stress conditions, extracellular ROS are mainly produced by plasma membrane-localized NADPH oxidases, whereas intracellular ROS are produced in multiple organelles. These ROS form a sophisticated cellular signaling network, with the accumulation of apoplastic ROS an early hallmark of stomatal movement. Here, we review recent progress in understanding the molecular mechanisms of the ROS signaling network, primarily during drought stress and pathogen attack. We summarize the roles of apoplastic ROS in regulating stomatal movement, ABA and CO2 signaling, and immunity responses. Finally, we discuss ROS accumulation and communication between organelles and cells. This information provides a conceptual framework for understanding how ROS signaling is integrated with various signaling pathways during plant responses to abiotic and biotic stress stimuli. 展开更多

The recretohalophyte with specialized saltsecreting structures including salt glands and salt bladders can secrete salt from their bodies and easily adapt themselves to many kinds of salt habitats.Salt glands and salt bladders,arose from dermatogen cells,are excretory organs specially adapted for dealing with ionic homeostasis in the cells of recretohalophytes.The main function of salt glands or salt bladders is to secrete excess ions that invade the plant.The structures of salt glands or salt bladders differ among plant species.In addition to structural differences,salt glands also differ in their secretion abilities.In this review,we mainly focus on recent progress in the mechanism of salt excretion of salt glands and salt bladders,and in particular,emphasize the vesicle-mediated secretion systems from the vacuole to the plasmalemma and the possibly involved membrane-bound translocating proteins for salt secretion of plant gland secretory cell. 展开更多

Both plant receptor-like protein kinases(RLKs)and ubiquitin-mediated proteolysis play crucial roles in plant responses to drought stress.However,the mechanism by which E3 ubiquitin ligases modulate RLKs is poorly understood.In this study,we showed that Arabidopsis PLANT U-BOX PROTEIN 11(PUB11),an E3 ubiquitin ligase,negatively regulates abscisic acid(ABA)-mediated drought responses.PUB11 interacts with and ubiquitinates two receptor-like protein kinases,LEUCINE RICH REPEAT PROTEIN 1(LRR1)and KINASE 7(KIN7),and mediates their degradation during plant responses to drought stress in vitro and in vivo.pub11 mutants were more tolerant,whereas Irr1 and kin7 mutants were more sensitive,to drought stress than the wild type.Genetic analyses show that the pub11 Irr1 kin7 triple mutant exhibited similar drought sensitivity as the Irr1 kin7 double mutant,placing PUB11 upstream of the two RLKs.Abscisic acid and drought treatment promoted the accumulation of PUB11,which likely accelerates LRR1 and KIN7 degradation.Together,our results reveal that PUB11 negatively regulates plant responses to drought stress by destabilizing the LRR1 and KIN7 RLKs. 展开更多
