Abstract:

Low-temperature(0-15 ℃)storage would trigger a series of the complicated physio- biochemical reactions in horticulture crops,damage the integrity,fluidity,and functionality (semi-permeability)of cell membranes,thereby causing chilling injury. To mitigate chilling damage,the CBF-(in)dependent signal transduction pathways are initiated in plants;among them,the CE1-CBF-COR transcriptional cascade is of great importance in the CBF-dependent signal transduction pathway. In addition,some endogenous hormones such as jasmonic acid(JA),ethylene(ETH)and abscisic acid(ABA) also rapidly accumulate during plant response to low temperature. JA and its derivatives are collectively referred to as JAs,which are formed after oxidation,cyclization,reduction,β-oxidation,modification and activation of α-linolenic acid or hexadecatrienoic acid. Upon JAs synthesis followed by perception by COI1,the transcription factor MYC2 is released from the repressor protein JAZs,which was ubiquitinated for degradation,to activate the downstream signal transduction process,causing the induction of several physio-biochemical alternations(including increment of antioxidant biosynthesis,improvement of antioxidant enzyme activity,inhibition of lipid metabolism,enhancement of arginine metabolism,promotion of energy metabolism,and activation of other plant hormone signal transduction pathways). The abovementioned responses would help to maintain the integrity,fluidity,and functionality(semi-permeability)of cell membrane,and thus improve the capacity of horticultural crops postharvest to resist low temperature stress. In recent years,studies have revealed that:(a)MYC2 regulates the transcription of downstream target genes by forming homodimers or heterodimers with MYC3 and MYC4;(b)BBX37 can activate the transcription of downstream CBFs genes independently or in synergy with ICE1;(c)MED16 enhances the stability of MED25,positively regulating the transcriptional output of JAs signaling,among other functions. This paper first elaborates on the characteristics of postharvest chilling injury in horticultural crops,reviews the roles of CBF-(in)dependent signal transduction pathways in plant responses to low-temperature stress,summarizes the biosynthesis,signaling pathways,and regulatory mechanisms of JAs,and introduces the applications and mechanisms of action of JAs in alleviating chilling injury in horticultural crops. Based on these,this paper systematically summarizes the association between the JAs signaling pathway and CBF-(in)dependent signal transduction pathways during low-temperature stress and proposes future research directions. Future research directions should focus on:(a)delving deeper into and validating the associations between JAs signaling pathways and CBF-(in)dependent signaling cascades;(b)elucidating the roles of post-transcriptional processing of genes and post-translational modifications of proteins in the synthesis or signaling transduction of JAs;(c)exploring the synergistic effects of JAs with other endogenous plant hormones in resistance to low temperature stress;and(d)dissecting the mechanisms of newly discovered components(MYC3/4,MED16,BBX37,etc.)in the low temperature response process.
