This week’s Arabidopsis Round-up brings you a new paper from researchers at the John Innes Centre on the subject of the genetic control of floral development. Also, in case you didn’t see our news story last week, here’s another chance for you to check out the GARNet team’s new J. Exp. Bot. paper, in which we report on the synthetic biology workshop we held at the University of Nottingham last summer.

  • Schiessl K, Muiño JM and Sablowski R. Arabidopsis JAGGED links floral organ patterning to tissue growth by repressing Kip-related cell cycle inhibitors. Proceedings of the National Academy of Sciences of the United States of America, 4 February 2014. DOI: 10.1073/pnas.1320457111. [Open Access]

Katharina Shiessl and Robert Sablowski from the John Innes Centre worked with a colleague from Berlin on this PNAS paper, in which they characterize the role of the Arabidopsis transcription factor JAGGED (JAG). Their work reveals that JAG directly mediates between the genetic pathways involved in cellular functions required for growth, and organ patterning; particularly the growth and shape of floral organs.
