Way were identified by KEGG enrichment annotation (Fig. 4: 5). KEGG evaluation MAO-A web showed that compared with CAK (BR spraying for 0 h), the expression of the UTPglucose-1-phosphate uridylyltransferase (UGP), SPS, glucose-6-phosphate isomerase (GPI), pyrophosphateJin et al. BMC Genomics(2022) 23:Web page ten ofFig. 5 A possible model in the BR signaling pathway with BRs (the activation state of BR signaling) sprayed onto tea leavesJin et al. BMC Genomics(2022) 23:Page 11 offructose-6-phosphate 1-phosphotransferase (PFP), and epidermis-specific secreted glycoprotein (EP) key regulatory genes associated towards the sucrose biosynthesis pathway were upregulated following BR spraying for three h, 9 h, 24 h, and 48 h.Exogenous spraying of BR onto tea leaves promotes the upregulated expression of genes inside the biosynthetic pathway of flavonoidsEleven genes involved in flavonoid biosynthesis had been identified by KEGG enrichment annotation (Fig. four: six). The flavonoid biosynthesis-related genes PAL, C4H, 4CL, chalcone synthase (CHS), chalcone isomerase (CHI), flavanone 3-hydroxylase (F3H), flavonoid 3,5-hydroxylase (F3’5’H), DFR, LAR, ANR, and UFGT have been upregulated, with peak values observed at 48 h.DiscussionBR signal transduction mechanism in tea leavesThrough KEGG enrichment and annotation, 26 genes involved within the BR signal transduction pathway have been identified. Based on the heat maps of genes associated to BR signal transduction under various BR treatments, it was discovered that 26 genes within the BR signal transduction pathway have been substantially upregulated with escalating BR spraying time. Combined together with the BR signal transduction maps of Arabidopsis and rice, we describe a doable model of your BR signal pathway in tea leaves [291] (Fig. 5). At present, the signal transduction pathway of BR in Arabidopsis and rice has been reported. Compared with rice, the signal transduction pathway of BR in tea leaves is comparable to that of Arabidopsis [24]. As opposed to the BR signal transduction pathway within a. thaliana, BAK1-like kinase includes both SERK and TMK4 in the BR signal transduction pathway of tea leaves. In our transcriptome information, the ATBS1-interacting things (AIF) and paclobutrazol resistance 1 (PRE) genes didn’t substantially differ in expression levels, whereas that of the teosinte branched (TCP) gene was significant. AIF is definitely the damaging regulator of BR signal transduction, although PRE and TCP would be the good regulators of BR signal transduction [34]. The outcomes showed that TCP, the forward regulator of BR signal transduction, plays a leading role in the effects of your exogenous spraying of BRs onto young tea leaves.Exogenous spraying of BR promotes the growth and development of tea plantsGBSS, and SBE genes associated to starch synthesis; as well as the flavonoid biosynthesis-related PAL, C4H, 4CL, CHS, CHI, F3H, F3’5, DFR, LAR, ANR, and UFGT genes had been identified. The results showed that exogenous spraying of BRs upregulated the expression of genes connected to sucrose synthesis, chlorophyll synthesis, starch synthesis, and flavonoid biosynthesis. It could be inferred that exogenous BR spraying increased the content material of sucrose, chlorophyll, starch, and flavonoids. Moreover, a sizable quantity of very expressed cyclin genes, such as Cyc, CycD3, CycD4, and CDC6, have been located. Cell cycle regulatory Oxazolidinone medchemexpress proteins can bind to cell differentiation cycle-coding proteins and activate corresponding protein kinases, hence advertising cell division. BRs can enhance plant growth by advertising cell division.
