Fig. 10: A working model for silencing MdGH3-2/12 in response to AMF inoculation and drought in apple.
From: Silencing MdGH3-2/12 in apple reduces drought resistance by regulating AM colonization
MdGH3-2/12 silencing resulted in the downregulation of MdD27, MdCCD7, MdCCD8a, MdCCD8b, and MdMAXa, and there was a corresponding change in root strigolactone content. Furthermore, we observed lower root dry weights in RNAi lines under AM inoculation conditions. Under drought stress, mycorrhizal transgenic plants showed higher sensitivity than WT, as indicated by higher relative electrolytic leakage and lower relative water contents, osmotic adjustment ability, ROS scavenging ability, gas exchange capacity, chlorophyll fluorescence values, and abscisic acid contents
