IN BRIEF by Kathleen L. Farquharson kfarquharson@aspb.org Alternative splicing (AS) regulates gene expression and greatly expands the coding capacity of complex genomes. By regulating which elements of an mRNA transcript are removed or retained, AS produces multiple transcripts from a single gene. Some…

IN BRIEF by Gregory Bertoni gbertoni@aspb.org RNA metabolism is key to a number of crucial processes in the cell, including transcription, RNA splicing, translation, and gene regulation. For efficient translation, mature mRNAs must have a 7-methylguanosine cap on the 5′ end to help recruit the translation…

IN BRIEF by Jennifer Lockhart jlockhart@aspb.org Heat and drought stress greatly restrict crop productivity, but most of what we know about a plant’s response to these stresses comes from controlled laboratory studies. This factor, along with the complex nature of these responses, has hampered efforts…
