چکیده
Each month, Chemistry & Biology Select highlights a selection of research reports from the recent literature. These highlights are a snapshot of interesting research done across the field of chemical biology. This month’s Select highlights a community-driven effort to improve drug sensitivity prediction algorithms, a report that XNAs can act as catalysts, and the role of galactolipids in systemic acquired resistance in plants.

Mono- and digalactosyldiacylglycerol lipids function nonredundantly to regulate systemic acquired resistance in plants.
The plant galactolipids monogalactosyldiacylglycerol (MGDG) and digalactosyldiacylglycerol (DGDG) have been linked to the anti-inflammatory and cancer benefits of a green leafy vegetable diet in humans due to their ability to regulate the levels of free radicals like nitric oxide (NO). Here, we show that DGDG contributes to plant NO as well as salicylic acid biosynthesis and is required for the...
متن کاملA re-examination in vivo of the phosphatidylcholine-galactolipid metabolic relationship during plant lipid biosynthesis.
It remains unclear how and in what form the lipids synthesized in plant endoplasmic reticulum are exported to chloroplasts and used as precursors for the biosynthesis of plastid galactolipids, which are the most abundant lipids on Earth. Neither the mechanism of transfer nor the nature of the lipids imported into plastids has been elucidated. To characterize events occurring in vivo, the labell...
متن کاملDiversity in Biosynthetic Pathways of Galactolipids in the Light of Endosymbiotic Origin of Chloroplasts
Cyanobacteria and chloroplasts perform oxygenic photosynthesis, and share a common origin. Galactolipids are present in the photosynthetic membranes of both cyanobacteria and chloroplasts, but the biosynthetic pathways of the galactolipids are significantly different in the two systems. In this minireview, we explain the history of the discovery of the cyanobacterial pathway, and present a prob...
متن کاملDGD1-independent biosynthesis of extraplastidic galactolipids after phosphate deprivation in Arabidopsis.
The galactolipids, mono- and digalactosyldiacylglycerol (DGDG), are the most common nonphosphorous lipids in the biosphere and account for 80% of the membrane lipids found in green plant tissues. These lipids are major constituents of photosynthetic membranes (thylakoids), and a large body of evidence suggests that galactolipids are associated primarily with plastid membranes in seed plants. A ...
