This discovery promises to transform agricultural practices, ensuring a sustainable supply of this vital resource for both dietary and industrial use.
Efficient Glycosyltransferases from Astragalus membranaceus Enable Biosynthesis of Bioactive Pterocarpan Glycosides
A research team has identified two highly efficient glycosyltransferases, AmGT28 and AmGT44, from Astragalus membranaceus, which convert medicarpin to medicarpin 3-O-glucoside and show a preference for pterocarpans over isoflavonoids.
Pear-derived discovery: a genetic mechanism to fortify crops against drought
A pivotal study has shed light on a critical genetic mechanism that boosts plants’ ability to withstand drought. The research uncovers the role of the transcription factor PbERF3, native to wild pears, which works in concert with the protein PbHsfC1a to regulate genes key to drought tolerance.
Unlocking the grape’s secret: how wounding boosts anthocyanin defenses
A recent study sheds light on the biochemical response of grapevines to wounding stress. It reveals that the transcription factor VvWRKY5 is a key regulator that enhances anthocyanin production, which serves as a protective mechanism for the plant.
Ripe for discovery: unraveling the genetic switches of pear maturation
A new study has revealed a key homeodomain transcription factor, PbHB.G7.2, that plays a crucial role in ethylene biosynthesis during pear fruit ripening. By binding to the promoter of the ethylene biosynthetic gene PbACS1b, PbHB.G7.2 enhances ethylene production, significantly impacting the ripening process.
