“…Genes encoding an auxin transporter-like protein 3 and a protein PIN-LIKES 3-like were also downregulated (Fig 8B). Auxin transport might have some relevance during fruit ripening, and it is proposed that less auxin transport from the fruits increases berry coloring (Serrano et al, 2022). Therefore, we suggest that ABA’s control of auxin transport-related genes might be relevant during ripening initiation.…”

Abscisic acid (ABA) plays a key role in the ripening process of non-climacteric fruits, triggering pigment production, fruit softening, and sugar accumulation. Transcriptomic studies show that ABA modifies the expression of several ripening-related genes, but to date, the epigenetic approach has not been utilized to characterize the role of ABA during this process. Therefore, this work aimed to perform transcriptomic and DNA methylation analyses of fruit samples treated with ABA during the fruit ripening process in the non-climacteric sweet cherry model. RNA-seq analyses revealed an overrepresentation of transcripts annotated in functional categories related to ABA response, secondary metabolism, and sugar synthesis. In contrast, Whole Genome Bisulfite Sequencing (WGBS) revealed DNA hypomethylation in the 5′UTR region of genes related to carotene catabolism. Genes encoding xyloglucan enzymes were regulated transcriptionally and epigenetically during ripening. ABA treatment enhanced color development and ripening. GO analysis of DEGs in the RNA-seq of the ABA treatment revealed expression variations in genes encoding members of the Aux/IAA and ARF families. In the WGBS, genes encoding enzymes of the cytokinin biosynthesis had differential DNA methylation after the ABA treatment. Our work shows the genetic factors modulated by ABA at the genetic and epigenetic levels during non-climacteric ripening.

“…Auxins also support a large number of development processes in the plant. Such processes include, among others, the formation of lateral roots, leaves and flowers, tropisms, differentiation of vascular tissues, as well as the formation of the apical-basal axis during the process of embryogenesis [29,30,53,54,76]. Despite research and great progress in understanding the mechanisms of their effect on plants, auxins still constitute a large field of studies for researchers [5,77].…”

The Impact of Auxin and Cytokinin on the Growth and Development of Selected Crops

With a very diverse structure and small molecules, phytohormones are regulators of plant growth and development. Despite the fact that they are synthesized by plants in small quantities, they are highly active physiologically. According to their action, phytohormones can be divided into two categories, as either activators of plant growth and development or as inhibitors, with auxins and cytokinins belonging to the former group. Auxins are synthesized by plants in the apical meristems of shoots, but also in young leaves, seeds, and fruits. They stimulate the elongation growth of shoots and initiate the production of adventitious and lateral roots. Cytokinins, in turn, are formed in root tips and in unripe fruits and seeds. These hormones are responsible for stimulating the growth of lateral shoots, they also stimulate cytokinesis and, consequently, cell division. The aim of this review paper is to present the progress of the research on the effect of selected auxins and cytokinins on crops, considering the prospect of using them in plant growing methods.
