Ordered rise and disordered fall: dynamic changes of membrane lipids during girdling-induced tree mortality in Populus yunnanensis.

Understanding the mechanisms behind drought-induced tree mortality is crucial for predicting the impact of global climate change on forests. We studied the mechanism at the cellular level in Populus yunnanensis by profiling membrane lipid molecules in leaves, branch phloem, top and bottom trunk phloem under trunk-girdling-induced drought conditions. We found that both lipid composition and content changed, depending on the tree's tissue positions and the progression of the girdling effect.

Subsequently, the CaRAV subfamily was classified into four branches based on homology with Arabidopsis thaliana, each exhibiting relatively conserved domains within the branch.

gen. nov., sp. nov. and sp. nov., isolated from desert soil.

Two Gram-stain-negative, aerobic, milk-white coloured, non-motile, short rod-shaped bacteria, designated as strains SYSU D60010 and SYSU D60012, were isolated from sand samples collected from the Taklimakan Desert of Xinjiang Province in China. Both strains were positive for oxidase, catalase and nitrate reduction, but negative for amylase, HS production, hydrolysis of gelatin and cellulase. Strains SYSU D60010 and SYSU D60012 grew well at 28 °C, at pH 7 and had the same NaCl tolerance range of 0-1 % (w/v).
