The growth and yield of tea plants are seriously limited by drought stress. Fatty acid desaturations (FADs) contribute to mediating membrane fluidity in response different stresses; however, the role ω-3 FAD (Omega-3 fatty desaturase)-mediated damage induced stress is poorly understood. In this study, significantly promoted synthesis C18:3 (linolenic acid) expression level CsFAD3. Yeast experiments further demonstrated that CsFAD3 can convert C18:2 35S:GFP-CsFAD3 fusion protein was localized endoplasmic reticulum Nicotiana benthamiana (N. benthamiana) cells. CsFAD3-silenced leaves exhibited poor tolerance, with lower Fv/Fm greater MDA (malondialdehyde) content compared those control plants. However, transgenic 35S:CsFAD3 Arabidopsis showed opposite phenotypes. addition, JA (jasmonic contents levels CsLOX2, CsLOX4, CsAOS, CsAOC3 CsOPR were reduced under no substantial difference SA (salicylic detected normal or conditions. Analysis Atcoi1 (JA receptor) Atnpr1 (SA mutant backgrounds revealed knockout impaired drought-tolerant phenotypes overexpression lines. Therefore, our study played a crucial tolerance pathways.

Tea plants (Camellia sinensis (L.) Kuntze) are a cash crop that thrive under warm and moist conditions. However, tea becoming increasingly vulnerable to heat damage (HD) during summer growing seasons due global climate warming. Because China ranks first in the world both harvested area total production, monitoring tracking HD timely manner has become significant urgent task for scientists producers China. In this study, spatiotemporal characteristics of evolution were analyzed, method using LST-weighted geographical centroids was constructed based on pixels identified by critical LST threshold daytime MYD11A1 products over major planting regions mainland from two typical years (2013 2022). Results showed average number days 2022 five more than 2013. Daily extent increased at rate 0.66% per day 2022, which faster 2013 with 0.21% day. years, greatest concentrated south Yangtze River (SYR), pixel ratios greater 50%, then north (NYR) southwest (SWC), around 40%. The least South (SC), where less centroid trajectories initially moved northeast, west. northeast west south. mainly conjunction SYR, SWC, SC 2013, northern SWC they near gardens. findings study confirmed large spatial reconstructed remotely sensed values an effective benefiting available MODIS products. Moreover, can identify track distribution manner, it will therefore be helpful taking preventative measures mitigate economic losses resulting HD.
