进一步研究证明,在低氮胁迫下,MhNAC1直接结合并抑制硝酸盐转运蛋白MhNRT2.4和柠檬酸转运蛋白MhMATE启动子的活性。过表达MhMATE或外施柠檬酸,促进了根系对氮的吸收,缓解了低氮胁迫,表明根系柠檬酸分泌的增加有助于氮素吸收。此外,MhNAC1是miR164的靶基因,沉默miR164或过表达MhNAC1抑制了根系氮素吸收。综上所述,这项...
miR164靶基因表达分析Nitrogen, an essential macronutrient for the growth and development of plants, affects above- ground biomass accumulation dramatically. Thus, it is very important to reveal the molecular mechanisms of howplants resist or adapt to low nitrogen availability. TheNAC1(NAM, ATAF, ...

NAC1, a target gene of miR164, directly regulates the expression of the high‐affinity nitrate transporter (MhNRT2.4) and citric acid transporter (MhMATE), affecting root nitrogen uptake.To examine the role of MhNAC1 in nitrogen uptake, we produced transgenic lines that overexpre...
In this study, we found that the IAA-miR164a-NAC100L1 module induced callose deposition to mediate the symbiotic incompatibility of cucumber/pumpkin grafted seedlings. The incompatible combination (IG) grafting interface accumulated more callose, and the activity of callose synthase (CmCalS1) and ...
In summary, miR164 inhibits the expression of LfNAC1 in spring and summer, later on LfNAC1 actives leaf senescence-associated genes to cause leaf senescence following a gradual decline of miR164 as the seasons change. The "miR164-NAC" regulatory mechanism was confirmed in Formosan sweet gum ...
