Salicylic acid-induced stomatal closure differs in vascular plants of various lineages.
Salicylic acid (SA)-triggering stomatal closure to prevent pathogen invasion has been widely recognized in angiosperms. However, whether SA-induced stomal closure differs across vascular plants of various lineages remains unclear. In this study, the stomatal responses of 28 species, including 13 angiosperms, 6 gymnosperms, 8 ferns, and 1 lycophyte, to exogenous SA were evaluated, and the stomatal closure signaling pathways of 6 representative species were subsequently examined. SA-induced stomatal closure was observed in seed plants but not in the ferns or lycophyte. Additionally, SA induced an increase in ROS in the guard cells of these 6 different vascular plants, but NO accumulation in and K+ efflux from guard cells were detected in seed plants but not in the 2 ferns or 1 lycophyte investigated. The application of SA induced large vacuolar compartments in the guard cells of the seed plants to disaggregate, whereas no such changes were observed in the guard cells of the ferns or lycophyte. The differences in the responses of the seed plant, fern, and lycophyte stomata to SA observed in this study were due mainly to the partial absence of the SA signaling pathway in the ferns and lycophyte.
期刊介绍:
The Journal of Experimental Botany publishes high-quality primary research and review papers in the plant sciences. These papers cover a range of disciplines from molecular and cellular physiology and biochemistry through whole plant physiology to community physiology.
Full-length primary papers should contribute to our understanding of how plants develop and function, and should provide new insights into biological processes. The journal will not publish purely descriptive papers or papers that report a well-known process in a species in which the process has not been identified previously. Articles should be concise and generally limited to 10 printed pages.
