MYB83 Is a Direct Target of SND1 and Acts Redundantly with MYB46 in the Regulation of Secondary Cell Wall Biosynthesis in Arabidopsis

Abstract: It has been proposed that the transcriptional regulation of secondary wall biosynthesis in Arabidopsis is controlled by a transcriptional network mediated by SND1 and its close homologs. Uncovering all the transcription factors and deciphering their interrelationships in the network are essential for our understanding of the molecular mechanisms underlying the transcriptional regulation of biosynthesis of secondary walls, the major constituent of wood and fibers. Here, we present functional evidence that the M… Show more

“…These facts suggest that SND1 functions as the master switch at the top of the hierarchy to upregulate MYB-type transcription factors, which, in turn, as the second and third regulators, upregulate the expression of genes encoding enzymes that catalyze secondary wall thickening during differentiation of xylem fiber cells. Similar regulation mechanisms for secondary wall formation are expected for VND6 and VND7 because VND6 and VND7 are able to regulate MYB46 and MYB83 expression (Zhong et al, 2008;McCarthy et al, 2009).…”

“…In our experiments, MYB46, MYB83, and MYB103 were upregulated by VND6 and SND1 (see Supplemental Data Set 1 online). Because these three MYB transcription factors are known to regulate secondary cell wall formation (Zhong et al, 2007(Zhong et al, , 2008McCarthy et al, 2009), they may be involved in processes of secondary wall formation that are common to xylem vessels and fibers. In addition, seven genes associated with the cytoskeleton, such as genes encoding tubulin, kinesin, and myosin, were upregulated by both VND6 and SND1.…”

“…Expression of ZmLP1 in maize leaves is high and confined to the developing transition zone (Li et al, 2010), supporting a role in laying down lipids in the walls of developing PBS cells. Similarly, SND2, a transcription factor known to be required for secondary cell wall synthesis in Arabidopsis (Zhong et al, 2008;McCarthy et al, 2009), is also expressed in the developing region of the maize leaf (Li et al, 2010) and is located on maize chromosome 3. In order to obtain a more complete picture of the genes involved in lipid deposition in OMA 3.01, analysis of PBS cell phenotypes in OMA radiation hybrid lines (Kynast et al, 2004) containing fragments of maize chromosome 3 in an oat background would permit finer mapping of this trait.…”

“…VND6 and VND7 are involved in xylem formation (Kubo et al, 2005;Demura and Fukuda, 2007;Du and Groover, 2010), while ANAC012 functions in xylary fiber development (Ko et al, 2007). Several NAC members including SND1, NST1 and NST3 were found to regulate secondary wall synthesis (Zhong et al, 2006;Mitsuda et al, 2007;Zhong et al, 2007a, b;McCarthy et al, 2009). Notably, a few members have been reported to participate in multiple processes, which might be a general rule for most NAC proteins.…”
