“…Importantly, key players in IAA homeostasis are under epigenetic regulation (Yamamuro et al, 2016; Do et al, 2019; Mateo‐Bonmati et al, 2019). Forgione et al (2019) detected increased TAA1 and YUC2 transcript levels in the leaves but not roots of the de novo DNA methylation mutant drm1 drm2 cmt3 ( ddc ) lacking the function of DOMAINS REARRANGED METHYLASE 1 (DRM1), DRM2, and CHROMOMETHYLASE 3 (CMT3) Arabidopsis , suggesting that auxin biosynthesis is regulated in a tissue‐specific manner by the RNA‐directed DNA methylation (RdDM) pathway.…”

Both phytohormone signaling and epigenetic mechanisms have long been known to play crucial roles in plant development and plasticity in response to ambient stimuli. Indeed, diverse signaling pathways mediated by phytohormones and epigenetic processes integrate multiple upstream signals to regulate various plant traits. Emerging evidence indicates that phytohormones and epigenetic processes interact at multiple levels. In this review, we summarize the current knowledge of the interplay between phytohormones and epigenetic processes from the perspective of phytohormone biology. We also review chemical regulators used in epigenetic studies and propose strategies for developing novel regulators using multidisciplinary approaches.

“…In leaf explants upon wounding, upregulation of YUC1 and YUC4 is accompanied by the removal of H3K27me3 (Chen et al, 2016 ). Do et al ( 2019 ) speculated in their review that the wound-jasmonate (JA) signal or even other environmental signals may trigger the recruitment of JMJ12/REF6. A recent study showed that JMJ14, JMJ15, and JMJ18 play key roles in high ambient temperature-induced YUC8 expression.…”

“…As one of the primary modes of transcriptional regulation, epigenetic modifications of the genome, which mainly include histone modifications in nucleosomes and DNA methylation modifications, change the structure of chromosomes or change the spatial structure of the modified DNA, resulting in gene silencing or overexpression. A number of reviews have summarized the functions of different epigenetic mechanisms in auxin signaling, transport, and metabolism (Yamamuro et al, 2016 ; Do et al, 2019 ; Mateo-Bonmati et al, 2019 ; Nguyen et al, 2020 ; Wojcikowska et al, 2020 ), two of which focused on epigenetic contributions to auxin biosynthesis. Mateo-Bonmati et al ( 2019 ) comprehensively described the relationships between epigenetic modifications and auxin homeostasis.…”

“…Mateo-Bonmati et al ( 2019 ) comprehensively described the relationships between epigenetic modifications and auxin homeostasis. Do et al ( 2019 ) highlighted the roles of epigenetic modifications in the YUC family genes, which are the most important genes in the auxin biosynthesis pathway. This review, based on emerging results, aims to provide an updated overview and some hypotheses about the effects of epigenetic modification on the regulation of auxin biosynthesis ( Table 1 ).…”

Auxin is one of the most important plant growth regulators of plant morphogenesis and response to environmental stimuli. Although the biosynthesis pathway of auxin has been elucidated, the mechanisms regulating auxin biosynthesis remain poorly understood. The transcription of auxin biosynthetic genes is precisely regulated by complex signaling pathways. When the genes are expressed, epigenetic modifications guide mRNA synthesis and therefore determine protein production. Recent studies have shown that different epigenetic factors affect the transcription of auxin biosynthetic genes. In this review, we focus our attention on the molecular mechanisms through which epigenetic modifications regulate auxin biosynthesis.

“…Chromatin modification was suggested to play important roles in regulating YUCs expression via H3 methylation, namely H3K27me3, to control cellular auxin concentration [161]. Do et al [162] have illustrated a precise and systemic picture of the emerging functions of chromatin modifications in YUCs in response to environmental alterations. However, translational and posttranslational regulations of YUC proteins remain largely unclear compared with other gene families in auxin biology, which needs further exploration.…”

Auxin plays essential roles in plant normal growth and development. The auxin signaling pathway relies on the auxin gradient within tissues and cells, which is facilitated by both local auxin biosynthesis and polar auxin transport (PAT). The TRYPTOPHAN AMINOTRANSFERASE OF ARABIDOPSIS (TAA)/YUCCA (YUC) pathway is the most important and well-characterized pathway that plants deploy to produce auxin. YUCs function as flavin-containing monooxygenases (FMO) catalyzing the rate-limiting irreversible oxidative decarboxylation of indole-3-pyruvate acid (IPyA) to form indole-3-acetic acid (IAA). The spatiotemporal dynamic expression of different YUC gene members finely tunes the local auxin biosynthesis in plants, which contributes to plant development as well as environmental responses. In this review, the recent advances in the identification, evolution, molecular structures, and functions in plant development and stress response regarding the YUC gene family are addressed.
