Identification of branch points and lariat RNAs during splicing in plants

Zhang et al. identified intronic branch points and lariat RNAs in four plant species.  By Binglian Zheng, Fudan University, China. Background: Most genes contain exons and introns; when genes are transcribed into precursor mRNAs, the introns must be removed and exons ligated to form mature mRNAs…

SME1 shapes plant development and freezing tolerance

Huertas et al. show that SME1 modulates spliceosome activity to shape plant development and tolerance to freezing temperatures.
