Abstract Phenylpropanoids are secondary metabolites produced by plants. They, by differential expression, are involved in responses to biotic and abiotic stresses and confer plant plasticity. In addition, they are synthesized under normal conditions during the fruit-ripening process. Therefore, the understanding of the mechanics involved in the accumulation of these compounds in plants is of extreme importance for the development of plants with greater resistance and tolerance to biotic and abiotic stresses, and plants with greater functional potential. There is evidence that one of the pathways of the induction of phenylpropanoids is dependent on abscisic acid (ABA) and it is generated by a signaling cascade involving calcium (Ca2+) and Ca2+-dependent protein kinases (CDPKs). Plants have several Ca2+ binding proteins that act as cellular sensors and represent the first points of signal transduction. CDPKs are mono-molecular Ca2+-sensor/kinase-effector proteins, which perceive Ca2+ signals and translate them into protein phosphorylation and thus represent an ideal tool for signal transduction. However, the mechanisms involved in the ABA–CDPK–phenylpropanoids crosstalk under stress conditions and during fruit ripening remains uncertain. Therefore, this review seeks to surface a new line of evidence as an attempt to understand the manner in which the induction of phenylpropanoids occurs in plants.

果实成熟过程中的串扰和脱落酸、钙依赖性蛋白激酶和苯丙烷的胁迫反应

摘要 苯丙烷是植物产生的次生代谢产物。它们通过差异表达参与对生物和非生物胁迫的反应并赋予植物可塑性。此外，它们是在果实成熟过程中在正常条件下合成的。因此，了解这些化合物在植物中积累的机制对于开发对生物和非生物胁迫具有更强抗性和耐受性的植物以及具有更大功能潜力的植物具有极其重要的意义。有证据表明苯丙烷类物质的诱导途径之一依赖于脱落酸 (ABA)，它是由涉及钙 (Ca2+) 和 Ca2+ 依赖性蛋白激酶 (CDPK) 的信号级联反应产生的。植物有几种 Ca2+ 结合蛋白，它们充当细胞传感器并代表信号转导的第一个点。CDPKs 是单分子 Ca2+ 传感器/激酶效应蛋白，可感知 Ca2+ 信号并将其转化为蛋白质磷酸化，因此是信号转导的理想工具。然而，ABA-CDPK-苯丙烷在胁迫条件下和果实成熟过程中串扰的机制仍不确定。因此，本综述试图揭示新的证据线，试图了解植物中苯丙烷的诱导方式。它感知 Ca2+ 信号并将其转化为蛋白质磷酸化，因此是信号转导的理想工具。然而，ABA-CDPK-苯丙烷在胁迫条件下和果实成熟过程中串扰的机制仍不确定。因此，本综述试图揭示新的证据线，试图了解植物中苯丙烷的诱导方式。它感知 Ca2+ 信号并将其转化为蛋白质磷酸化，因此是信号转导的理想工具。然而，ABA-CDPK-苯丙烷在胁迫条件下和果实成熟过程中串扰的机制仍不确定。因此，本综述试图揭示新的证据线，试图了解植物中苯丙烷的诱导方式。
