摘要Arabidopsis C3H14 and C3H15 have overlapping roles in the regulation of secondary wall thickening and anther development. C3H14 contributes more to secondary wall thickening while C3H15 is more important in anther development.Plant tandem CCCH zinc finger (TZF) proteins play diverse roles in developmental and adaptive processes. Arabidopsis C3H14 has been shown to act as a potential regulator of secondary wall biosynthesis. However, there is lack of direct evidence to support its functions in Arabidopsis. It is demonstrated here that C3H14 and its homologue C3H15 redundantly regulate secondary wall formation and that they additionally function in anther development. Plants with double, but not single, T-DNA mutants for C3H14 or C3H15 have few pollen grains and thinner stem secondary walls than the wild type. Plants homozygous for c3h14 and heterozygous for c3h15 [c3h14 c3h15(+/-)] have slightly thinner secondary walls than plants heterozygous for c3h14 and homozygous for c3h15 [c3h14(+/-) c3h15], and c3h14(+/-) c3h15 have lower fertility. Overexpression of C3H14 or C3H15 led to increased secondary wall thickness in stems and the ectopic deposition of secondary walls in various tissues, but did not affect anther morphology. Transcript profiles from the C3H14/15 overexpression and c3h14 c3h15 plants revealed marked changes in the expression of many genes associated with cell wall metabolism and pollen formation. Subcellular localization and biochemical analyses suggest that C3H14/15 might function at both the transcriptional and post-transcriptional levels.
