GNOBB would like to congratulate Dr. Enamul Huq and his group at University of Texas at Austin, USA for publishing two articles in the prestigious journals Plant Cell and Nature communication respectively. The plant cell article is entitled “Coordinated Regulation of Pre-mRNA Splicing by the SFPS-RRC1 Complex to Promote Photomorphogenesis” where they identified one splicing factor RRC1 (Reduced Red-light responses in Cry1cry2 background 1) as
one of the interacting proteins of SFPS and phyB. Through RNA- seq analysis authors showed that RRC1 regulates the expression and pre-mRNA splicing of large number of genes, both under dark and red- light treatment. Over all, this work provides a comprehensive view of yet another novel molecular mechanism of phytochrome-mediated signaling to promote photomorphogenesis in Arabidopsis. The Nature Communication article is entitled “A phyB-PIF1-SPA1 kinase regulatory complexpromotes photomorphogenesis in Arabidopsis”, where they provide a biochemical mechanism for one of the most important questions in the field of phytochrome-mediated light signaling pathways; how do phytochromes trigger rapid phosphorylation and degradation of their target proteins? They demonstrate that a long-sought protein kinase SPA1 is responsible for the light-induced phosphorylation of PHYTOCHROME INTERACTING FACTOR 1 (PIF1). Dr. Huq is a former student of Department of Biochemistry and Molecular Biology, Dhaka University and a founder member of GNOBB. We wish all the best to Dr. Huq and his team.
