Stimulatory involvement of abscisic acid in wound suberization of postharvest kiwifruit

Three Transcription Activators of ABA Signaling Positively Regulate Suberin Monomer Synthesis by Activating Cytochrome P450 CYP86A1 in Kiwifruit

“…hydroxyacids and a, w-diacids that are essential for suberin assemble (Höfer et al, 2008;Serra et al, 2009;Graç a et al, 2015). The catalytic property of AtCYP86A1 in vitro is identified from yeast expressing CYP86A1, which actively metabolized fatty acids with chain lengths C12-C18 to corresponding w-hydroxyacids, showing a preference for C16 and C18:1 fatty acids (Benveniste et al, 1998).…”

“…Furthermore, suberization is one of the hallmarks of wound damage and is well known to occur in cases of abiotic and biotic stress conditions. Chemically, suberin is a complex lipid polymer consisting of aliphatics and aromatics (Graç a et al, 2015;Vishwanath et al, 2015). The aliphatics are supposed to be the main reason for the physiological important water-sealing and fungal-resisting properties of suberin (Lulai and Corsini, 1998).…”

A Multilevel Study of Melon Fruit Reticulation Provides Insight into Skin Ligno-Suberization Hallmarks

“…The list includes 50 genes that exhibited significantly altered expression in reticulated versus smooth skin tissue according to transcriptome analyses. The genes listed represent part of the 173 common genes in the Venn diagram presented in Figure 10A (see full list of common genes in Supplemental Table S3 confined to the outermost layer of fruit skin surface was also reported in potato tubers (Kolattukudy, 1981;Graça and Pereira, 2000), wounded tomato (Tao et al, 2016), and kiwifruit (Actinidia deliciosa; Han et al, 2017). In the same way, we assume that the initiation of lignosuberization in melon is part of a developmental wound response occurring when the magnitude of tension forces applied on skin surfaces during fruit enlargement exceeds a certain threshold.…”

ABF2 and MYB transcription factors regulate feruloyl transferase FHT involved in ABA-mediated wound suberization of kiwifruit

“…ABA is a broad-spectrum phytohormone involved in a host of biological processes, including responses to biotic and abiotic factors (Yoshida et al, 2010, 2015). There is accumulating evidence to indicate that ABA plays a positive role in suberin biosynthesis in a variety of different species and tissues, including Arabidopsis roots (Efetova et al , 2007), potato tubers (Boher et al , 2013), tomato fruit (Leide et al , 2012), and kiwifruit (Han et al , 2017). Our previous studies have indicated that ABA can increase wound-associated deposition of suberin, with a concomitant increase in the expression of suberin biosynthetic genes in kiwifruit (Han et al, 2017, 2018) and tomato fruit (Tao et al , 2016).…”

The blocking of ABA biosynthesis by fluridone (FLD) provides a reliable means of determining the role of ABA in wound-induced suberization in potato tubers (Lulai et al , 2008) and tomato fruit (Tao et al , 2016).…”
