Apple SINA E3 ligase MdSINA3 negatively mediates JA‐triggered leaf senescence by ubiquitinating and degrading the MdBBX37 protein

SUMMARY Jasmonic acid (JA) induces chlorophyll degradation and leaf senescence. B‐box (BBX) proteins play important roles in the modulation of leaf senescence, but the molecular mechanism of BBX protein‐mediated leaf senescence remains to be further studied. Here, we identified the BBX protein MdBBX...
