The XVP/NAC003 protein is a NAC domain transcription factor associated with the plasma membrane and involved in the TDIF-PXY signaling during vascular development. We report here the mechanisms of XVP membrane localization and its nuclear translocation. Using a transient transformation approach, we found that XVP is associated with the plasma membrane through positively charged KR-rich regions. Mutagenesis studies found that the threonine amino acid at position 354 (T354) is critical for XVP translocation to the nucleus. In particular, the threonine to alanine mutation (T354A) resulted in a partial nucleus localization, while threonine to aspartic acid (T354D) mutation showed no effect on protein localization, indicating that dephosphorylation at T354 may serve as a nucleus translocation signal.

Here we monitored transcriptome and phytohormones changes specifically in elongating coleoptile/mesocotyl in response to DSS and 24-epibrassinolide (EBR)-signaling. Phenotypically, contrasting maize evolved variant organs to positively respond to DST, longer coleoptile/mesocoty of K12/W64A was a desirable organ for seedling under DSS. Applied-EBR improved maize DST, and their coleoptiles/mesocotyls were further elongated. 15,607/20,491 differentially expressed genes (DEGs) were identified in W64A/K12 coleoptile, KEGG analysis showed plant hormone signal transduction, starch and sucrose metabolism, valine, leucine, and isoleucine degradation were critical processes of coleoptile elongation under DSS and EBR signaling, further highly interconnected network maps including 79/142 DEGs for phytohormones were generated. Consistent with these DEGs expression, interactions, and transport, IAA, GA₃, ABA, and Cis-ZT were significantly reduced while EBR, Trans-ZT, JA, and SA were clearly increased in coleoptile under DSS and EBR-signaling.

In rice, sucrose transporters, <i>OsSUTs</i> (sucrose transporters) and <i>OsSWEETs</i> (sugars are eventually exported transporters) import sucrose and export cells between phloem parenchyma cells and companion cells. Before sucrose transporters perform their functions, several transcription factors can induce sucrose transporter gene transcription levels, such as <i>Oryza sativa</i> DNA binding with one finger 11 (<i>OsDOF11</i>) and <i>Oryza sativa</i> Nuclear Factor Y B1 (<i>OsNF-YB1</i>).

Here we report that they also accumulate the benzyl glucosinolate hydrolysis products benzyl isothiocyanate and benzyl cyanide, which indicates that the turnover of benzyl glucosinolate can occur in intact tissues.

However, transcriptomics analysis detected no substantial increase in expression of known myrosinases or putative β-glucosidases in <i>AtCYP79A2</i> overexpressing lines. It was previously shown that accumulation of aldoximes or their derivatives represses the phenylpropanoid pathway. For instance, <i>ref2</i> mutant having a defect in one of the aldoxime catabolic enzymes decreases phenylpropanoid production. Considering that <i>AtCYP79A2</i> is not expressed in most organs under optimal growth condition, <i>ref2</i> accumulates aliphatic aldoximes but not PAOx. Interestingly, overexpression of <i>AtCYP79A2</i> in <i>ref2</i> resulted in a further decrease in sinapoylmalate content compared to <i>ref2</i>.
