NST- and SND-subgroup NAC proteins coordinately act to regulate secondary cell wall formation in cotton

Secondary cell wall (SCW) has a strong impact on plant growth and adaptation to the environments. Previous studies have shown that NAC (NAM, ATAF1/2, and CUC2) transcription factors act as key regulators of SCW biosynthesis. However, the regulatory network triggered by NAC proteins is largely unknow...

520			\|a Secondary cell wall (SCW) has a strong impact on plant growth and adaptation to the environments. Previous studies have shown that NAC (NAM, ATAF1/2, and CUC2) transcription factors act as key regulators of SCW biosynthesis. However, the regulatory network triggered by NAC proteins is largely unknown, especially in cotton, a model plant for SCW development studies. Here, we show that several cotton NAC transcription factors are clustered in the same group with Arabidopsis secondary wall NACs (SWNs), including secondary wall-associated NAC domain protein1 (SND1) and NAC secondary wall thickening promoting factor1/2 (NST1/2), so we name these cotton orthologs as SND1s and NST1s. We found that simultaneous silencing of SND1s and NST1s led to severe xylem and phloem developmental defect in cotton stems, however silencing either SND1s or NST1s alone had no visible phenotype. Silencing both SND1s and NST1s but not one subgroup caused decreased expression of a set of SCW-associated genes, while over-expression of cotton SWNs in tobacco leaves resulted in SCW deposition. SWNs could bind the promoter of MYB46 and MYB83, which are highly expressed in SCW-rich tissues of cotton. In total, our data provide evidence that cotton SWNs positively and coordinately regulate SCW formation.

Previous studies have shown that NAC (NAM, ATAF1/2, and CUC2) transcription factors act as key regulators of SCW biosynthesis. However, the regulatory network triggered by NAC proteins is largely unknown, especially in cotton, a model plant for SCW development studies. Here, we show that several cotton NAC transcription factors are clustered in the same group with Arabidopsis secondary wall NACs (SWNs), including secondary wall-associated NAC domain protein1 (SND1) and NAC secondary wall thickening promoting factor1/2 (NST1/2), so we name these cotton orthologs as SND1s and NST1s. We found that simultaneous silencing of SND1s and NST1s led to severe xylem and phloem developmental defect in cotton stems, however silencing either SND1s or NST1s alone had no visible phenotype. Silencing both SND1s and NST1s but not one subgroup caused decreased expression of a set of SCW-associated genes, while over-expression of cotton SWNs in tobacco leaves resulted in SCW deposition. SWNs could bind the promoter of MYB46 and MYB83, which are highly expressed in SCW-rich tissues of cotton. In total, our data provide evidence that cotton SWNs positively and coordinately regulate SCW formation.

title_auth	NST- and SND-subgroup NAC proteins coordinately act to regulate secondary cell wall formation in cotton
abstract	Secondary cell wall (SCW) has a strong impact on plant growth and adaptation to the environments. Previous studies have shown that NAC (NAM, ATAF1/2, and CUC2) transcription factors act as key regulators of SCW biosynthesis. However, the regulatory network triggered by NAC proteins is largely unknown, especially in cotton, a model plant for SCW development studies. Here, we show that several cotton NAC transcription factors are clustered in the same group with Arabidopsis secondary wall NACs (SWNs), including secondary wall-associated NAC domain protein1 (SND1) and NAC secondary wall thickening promoting factor1/2 (NST1/2), so we name these cotton orthologs as SND1s and NST1s. We found that simultaneous silencing of SND1s and NST1s led to severe xylem and phloem developmental defect in cotton stems, however silencing either SND1s or NST1s alone had no visible phenotype. Silencing both SND1s and NST1s but not one subgroup caused decreased expression of a set of SCW-associated genes, while over-expression of cotton SWNs in tobacco leaves resulted in SCW deposition. SWNs could bind the promoter of MYB46 and MYB83, which are highly expressed in SCW-rich tissues of cotton. In total, our data provide evidence that cotton SWNs positively and coordinately regulate SCW formation.
