ISWI chromatin remodeling complex plays a crucial role in plant development. In this issue, Gu et al. (pp. 1703–1716) report FHA2 as a novel subunit of ISWI complex in Arabidopsis that participates in regulating plant fertility by interacting with RLTs. The cover image shows the reproductive defects caused by the mutation of ISWI complex, which is a consequence of failure in fertilization due to impaired stamen filament elongation.

ISWI染色质重塑复合物在植物发育中起关键作用。在本期中，Gu等。（第1703–1716页）报道了FHA2是拟南芥ISWI复合物的一个新亚基，它通过与RLT相互作用参与调节植物的育性。封面图像显示了由ISWI复合体突变引起的生殖缺陷，这是由于雄蕊花丝伸长受损而导致施肥失败的结果。
