“…In this study, fragment duplication was identified as having a prominent role in Ipomoea PYL gene expansion. Similar situations were also reported in the PYLs from apple, cucumber, Medicago sativa, and Prunus avium [14,36,39,41]. Moreover, there is the largest number of collinear gene pairs between I. batatas and I. trifida, I. triloba, indicating that their two diploid wild relatives play key roles in the evolution of sweetpotato PYL genes, which is consistent with that of our previous reports of multiple transcription factor families [28,38,42].…”

Abscisic acid (ABA), a critical phytohormone that regulates plant development and stress response, is sensed by the ABA receptors PYR/PYL/RCAR (PYLs). The PYL genes have been widely studied in multiple plant species, while a systematic analysis of PYL genes in the genus Ipomoea remains unperformed. Here, a total of 13, 14, and 14 PYLs were identified in Ipomoea batatas, Ipomoea trifida, and Ipomoea triloba, respectively. Fragment duplication was speculated to play prominent roles in Ipomoea PYL gene expansions. These Ipomoea PYLs were classified into three subfamilies via phylogenetic analysis, which was supported by exon–intron structures and conserved motif analyses. Additionally, the interspecies collinearity analysis further depicted a potential evolutionary relationship between them. Moreover, qRT-PCR analysis showed that multiple IbPYLs are highly and differentially responsive to abiotic stress treatments, suggesting their potential roles in sweetpotato stress responses. Taken together, these data provide valuable insights into the PYLs in the genus Ipomoea, which may be useful for their further functional analysis of their defense against environmental changes.

“…In this study, 19 HaPYL genes were identified in the sunflower genome. Compared with the number of PYL genes in other reported diploid plants, including A. thaliana (14) ( Ma et al, 2009 ; Park et al, 2009 ), rice (13) ( Yadav et al, 2020 ), sweet cherry (11) ( Zhou et al, 2023 ), poplar (14) ( Yu et al, 2016 ), and rubber tree (14) ( Guo et al, 2017 ), the number of HaPYL s in the sunflower is greater. This implies that HaPYL s may be important in sunflower development and used in environmental adaptation.…”

“…The PYL receptor is a core component of ABA signaling and essential for activating the ABA signaling cascade response. Considering the importance of ABA receptors (PYL s ) in the ABA signaling pathway, studies of the PYL genes have been reported in several species, including A. thaliana ( Ma et al, 2009 ; Park et al, 2009 ), rice ( Yadav et al, 2020 ), sweet cherry ( Zhou et al, 2023 ), poplar ( Yu et al, 2016 ), and rubber tree ( Guo et al, 2017 ). However, work on PYL genome-wide characterization in the sunflower is limited, which hampers the study of their developmental functions and roles in abiotic stress resistance.…”

In the context of global climate change, drought and soil salinity are some of the most devastating abiotic stresses affecting agriculture today. PYL proteins are essential components of abscisic acid (ABA) signaling and play critical roles in responding to abiotic stressors, including drought and salt stress. Although PYL genes have been studied in many species, their roles in responding to abiotic stress are still unclear in the sunflower. In this study, 19 HaPYL genes, distributed on 15 of 17 chromosomes, were identified in the sunflower. Fragment duplication is the main cause of the expansion of PYL genes in the sunflower genome. Based on phylogenetic analysis, HaPYL genes were divided into three subfamilies. Members in the same subfamily share similar protein motifs and gene exon-intron structures, except for the second subfamily. Tissue expression patterns suggested that HaPYLs serve different functions when responding to developmental and environmental signals in the sunflower. Exogenous ABA treatment showed that most HaPYLs respond to an increase in the ABA level. Among these HaPYLs, HaPYL2a, HaPYL4d, HaPYL4g, HaPYL8a, HaPYL8b, HaPYL8c, HaPYL9b, and HaPYL9c were up-regulated with PEG6000 treatment and NaCl treatment. This indicates that they may play a role in resisting drought and salt stress in the sunflower by mediating ABA signaling. Our findings provide some clues to further explore the functions of PYL genes in the sunflower, especially with regards to drought and salt stress resistance.

“…ABA plays an important role in many stages of the plant life cycle and in the response of plants to various environmental stresses [42]. In recent years, the ABA signaling pathway and its functions under stress response have attracted increasing attention [43]. However, the role of the grapevine ABA pathway in weak light stress responses remains unclear.…”

Suboptimal light stress in grapevines is increasing worldwide with the spread of grapevine cultivation, which can affect grapevine physiology and productivity, such as in Southern China. Abscisic acid (ABA) is an important hormone in plant adaptive responses to abiotic stress, including low light stress. However, ABA signaling pathway genes (APGs) are not well characterized in the grapevine, and little is known of their potentially mitigating role in grapevine growth under weak light stress. Our study aimed to explore the potential role of the ABA signaling pathway in the response of grapevines to suboptimal light conditions. In this study, APGs were identified in the grapevine genome, and the distribution of conserved motifs was shown to reflect their phylogenetic relationships. Gene duplication analysis indicated that segmental duplication was an important driver for gene expansion in the grapevine ABA signaling pathway. Suboptimal conditions of light were shown to seriously affect the growth of grapevine leaves and berries, with the differential regulation of APGs in the grapevine. Our study summarizes the basic characteristics of APGs in grapevine, which can now be examined further for their roles in grapevine’s response to suboptimal light conditions.
