WebApr 21, 2016 · Many studies have previously reported that ABA may play a positive role in regulating ethylene action during fruit ripening [2,3,17,21,89]. Combining RNA-seq with RT-PCR analysis, our study may provide crucial molecular insights into the key genes affected by ABA in the pathway of ethylene biosynthesis and signaling (Figs 4 and 6). WebPlant hormones play a crucial role in controlling the way in which plants grow and develop. While metabolism provides the power and building blocks for plant life, it is the hormones that regulate the speed of growth of the individual parts and integrate them to produce the form that we recognize as a plant.
