Way have been identified by KEGG enrichment annotation (Fig. four: 5). KEGG analysis showed that compared with CAK (BR Tetracycline manufacturer spraying for 0 h), the expression on the UTPglucose-1-phosphate uridylyltransferase (UGP), SPS, glucose-6-phosphate isomerase (GPI), pyrophosphateJin et al. BMC Genomics(2022) 23:Page 10 ofFig. 5 A attainable model from 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 related towards the sucrose biosynthesis pathway have been upregulated just after 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 IRAK list involved in flavonoid biosynthesis had been identified by KEGG enrichment annotation (Fig. four: 6). The flavonoid biosynthesis-related genes PAL, C4H, 4CL, chalcone synthase (CHS), chalcone isomerase (CHI), flavanone 3-hydroxylase (F3H), flavonoid three,5-hydroxylase (F3’5’H), DFR, LAR, ANR, and UFGT were upregulated, with peak values observed at 48 h.DiscussionBR signal transduction mechanism in tea leavesThrough KEGG enrichment and annotation, 26 genes involved in the BR signal transduction pathway were identified. In accordance with the heat maps of genes associated to BR signal transduction beneath diverse BR therapies, it was located that 26 genes inside the BR signal transduction pathway were considerably upregulated with growing BR spraying time. Combined together with the BR signal transduction maps of Arabidopsis and rice, we describe a probable model of the 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 similar to that of Arabidopsis [24]. As opposed to the BR signal transduction pathway within a. thaliana, BAK1-like kinase consists of each SERK and TMK4 in the BR signal transduction pathway of tea leaves. In our transcriptome data, the ATBS1-interacting factors (AIF) and paclobutrazol resistance 1 (PRE) genes didn’t substantially differ in expression levels, whereas that on the teosinte branched (TCP) gene was considerable. AIF would be the unfavorable regulator of BR signal transduction, whilst PRE and TCP would be the constructive regulators of BR signal transduction [34]. The results showed that TCP, the forward regulator of BR signal transduction, plays a leading function within the effects on the exogenous spraying of BRs onto young tea leaves.Exogenous spraying of BR promotes the growth and improvement of tea plantsGBSS, and SBE genes associated to starch synthesis; and the flavonoid biosynthesis-related PAL, C4H, 4CL, CHS, CHI, F3H, F3’5, DFR, LAR, ANR, and UFGT genes have been identified. The outcomes showed that exogenous spraying of BRs upregulated the expression of genes associated to sucrose synthesis, chlorophyll synthesis, starch synthesis, and flavonoid biosynthesis. It might be inferred that exogenous BR spraying improved the content material of sucrose, chlorophyll, starch, and flavonoids. Moreover, a big quantity of very expressed cyclin genes, such as Cyc, CycD3, CycD4, and CDC6, were identified. Cell cycle regulatory proteins can bind to cell differentiation cycle-coding proteins and activate corresponding protein kinases, thus promoting cell division. BRs can improve plant growth by advertising cell division.
