摘要: Abstract The plants growing in high altitude Ladakh Himalayas experience significant temperature variations during their vegetative growth. In this study, the photosynthetic response of Lepidium latifolium L., a sleeper weed, was investigated to short term fluctuations. This plant maintained photosynthesis at higher temperatures by modulating photochemical efficiency photosystem II. Various physiological mechanisms including VpdL dependent and independent stomatal opening, increase energy fluxes, closing reaction centers, chlorophyll content play crucial role tolerance. An efficient dynamic non-photochemical quenching involving both zeaxanthin PsbS dissipated excess temperatures. degradation apparatus is compensated increased expression subunit proteins. Other genetic elements that help repair stabilization were also induced. Allyl isothiocyanate modulation aperture acts as swift mechanism for CO2 exchange evapotranspirational requirements. Collectively, these processes mitigate harmful effects on process. data will strategize spread an ecologically sensitive climate change scenario.
