Abstract
- The involvement of the ABA INSENSITIVE 5 (ABI5) binding protein family (AFPs), closely related to NOVEL INTERACTOR OF JAZ (NINJA) proteins, has been revealed in several aspects of plant development related to multifaceted plant abscisic acid (ABA) responses. The abundance of AFP proteins is tightly regulated, and they function as a rheostat for ABA responses through several nonmutually exclusive molecular mechanisms. AFP proteins regulate important biological processes in plants, which are tightly controlled by transcriptional repressors and phytohormone-mediated pathways, specifically ABA, gibberellic acid (GA), and jasmonic acid. In today's world, the most pressing concerns are food security and dynamic climatic conditions. Enriching our knowledge regarding plants' survival and growth strategies through addressing the inherent voids in plant AFP research might foster improvements in various crop species through genetic manipulation. During the course of terrestrial evolution, plants have developed complex networks that involve the coordination of phytohormone signalling pathways in order to adapt to an ever-changing environment. Transcription factors coordinate these responses by engaging in different protein complexes and exerting both positive and negative effects. ABA INSENSITIVE 5 (ABI5) binding proteins (AFPs), which are closely related to NOVEL INTERACTOR OF JAZ (NINJA)-like proteins, are known for their fundamental role in plants' morphological and physiological growth. Recent studies have shown that AFPs regulate several hormone-signalling pathways, including abscisic acid (ABA) and gibberellic acid (GA). Here, we review the genetic control of AFPs and their crosstalk with plant hormone signalling, and discuss the contributions of AFPs to plants' growth and development. [ABSTRACT FROM AUTHOR]
