Zhilong Bie team from Huazhong Agricultural University revealed the molecular mechanism of CmoDREB2A and CmoNAC1 in pumpkin regulating the salt tolerance of grafted cucumber
Chinese Academy of SciencesCucumber (Cucumis sativus L.) holds significant importance among greenhouse vegetables in China, despite its relatively low salt tolerance. Grafting cucumber onto pumpkin rootstocks, which exhibit strong salt tolerance, can improve its resistance to saline conditions. Earlier research conducted by the team revealed that the pumpkin rootstock CmoNAC1 boosts salt tolerance in grafted cucumbers by modulating H2O2/ABA signaling and maintaining K+/Na+ balance through its interaction with the promoters of CmoRBOHD1/CmoNCED6 and CmoAKT1;2/CmoHKT1;1.
