Drought significantly limits apple fruit production and quality. Decoding the key genes involved in drought stress tolerance is important for breeding varieties with improved drought resistance. Here, we identified GRETCHEN HAGEN3.6 (GH3.6), an indole-3-acetic acid (IAA) conjugating enzyme, to be a neg. regulator of water-deficit stress tolerance in apple. Overexpressing MdGH3.6 reduced IAA content, adventitious root number, root length and water-deficit stress tolerance, whereas knocking down MdGH3.6 and its close paralogs increased IAA content, adventitious root number, root length and water-deficit stress tolerance. Moreover, MdGH3.6 neg. regulated the expression of wax biosynthetic genes under water-deficit stress and thus neg. regulated cuticular wax content. Addnl., MdGH3.6 neg. regulated reactive oxygen species scavengers, including antioxidant enzymes and metabolites involved in the phenylpropanoid and flavonoid pathway in response to water-deficit stress. Further study revealed that the homolog of transcription factor AtMYB94, rather than AtMYB96, could bind to the MdGH3.6 promoter and neg. regulated its expression under water-deficit stress conditions in apple. Overall, our results identify a candidate gene for the improvement of drought resistance in fruit trees. This study involved multiple reactions and reactants, such as (2R,2’R,3R,3’R,4R)-2,2′-Bis(3,4-dihydroxyphenyl)-[4,8′-bichromane]-3,3′,5,5′,7,7′-hexaol (cas: 29106-49-8SDS of cas: 29106-49-8).
(2R,2’R,3R,3’R,4R)-2,2′-Bis(3,4-dihydroxyphenyl)-[4,8′-bichromane]-3,3′,5,5′,7,7′-hexaol (cas: 29106-49-8) belongs to alcohols. Alcohols are among the most common organic compounds. They are used as sweeteners and in making perfumes, are valuable intermediates in the synthesis of other compounds, and are among the most abundantly produced organic chemicals in industry. Under carefully controlled conditions, simple alcohols can undergo intermolecular dehydration to give ethers. This reaction is effective only with methanol, ethanol, and other simple primary alcohols.SDS of cas: 29106-49-8
