CjNAC43 and CjNAC54 are significantly upregulated during the critical senescence phase in Clerodendrum japonicum.
Quoted textsource-backed
<i>CjNAC43</i> and <i>CjNAC54</i> exhibited significantly upregulated expression during the critical senescence phase (90-130 days).
CjNAC43 and CjNAC54 function as positive regulators of leaf senescence in Clerodendrum japonicum.
Quoted textsource-backed
In conclusion, our results demonstrate that <i>CjNAC43</i> and <i>CjNAC54</i> function as positive regulators of leaf senescence in <i>C. japonicum</i>, partly by mediating ABA and dark signaling pathways.
Silencing CjNAC43 or CjNAC54 in Clerodendrum japonicum delays leaf senescence.
Quoted textsource-backed
Conversely, silencing <i>CjNAC43</i> or <i>CjNAC54</i> in <i>C. japonicum</i> delayed senescence.
Overexpression of CjNAC43 or CjNAC54 in Arabidopsis thaliana accelerates leaf senescence, upregulates senescence-associated genes, and reduces chlorophyll content.
Quoted textsource-backed
Overexpression of either gene in <i>A. thaliana</i> accelerated leaf senescence, up-regulated senescence-associated genes (<i>SAG</i>s), and reduced chlorophyll content.
CjNAC43 and CjNAC54 enhance sensitivity to ABA and darkness, accelerating senescence under these stresses.
Quoted textsource-backed
Both genes enhanced the plant's sensitivity to ABA and darkness, leading to accelerated senescence under these stresses.
