MED25 regulates the alternative splicing of JAZ genes through recruitment of splicing factors PRP39 and PRP40

Wu et al. investigated MED25 recruits splicing factors to regulate the alternative splicing of JAZ genes in Arabidopsis. The Plant Cell (2019). https://doi.org/10.1105/tpc.19.00583   Background: The jasmonate (JA) signaling pathway controls resource allocation between growth- and defense-related…

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. Plant Cell https://doi.org/10.1105/tpc.18.00689   By Raúl Huertas, Noble Research Institute, Admore, Oklahoma, USA. Rafael Catalá, Centro de Investigaciones Biológicas-CSIC,…
