Flowering in response to cold in annual and perennial plants
by Jens Sundström Department of Plant Biology, Swedish University of Agricultural Sciences, Uppsala, Sweden. In relation to annual plants, perennial plants initiate flowering after a more extended juvenile period. Also, perennial plants can often initiate flowering during repeated seasonable cycles … Continue reading
Modelling vernalization response – fast and slow
by Aalt-Jan van Dijk Wageningen University, The Netherlands In one of my previous commentaries (see ‘A hitchhiker guide to modelling’), I discussed some issues related to the development of computational models for the molecular regulation of flowering. One aspect that … Continue reading

Polyploidy – from evolution to development?
by Rainer Melzer School of Biology and Environmental Science and Earth Institute, University College Dublin A large variety of molecular mechanisms regulate developmental processes. Transcription factors entered the stage already decades ago and are still widely considered master regulators of … Continue reading

DELLA proteins restrict cell divisions by distinct mechanisms
by Jens Sundström Swedish University of Agricultural Sciences Breeding cereal crops with reduced stem length, in so-called semi-dwarf varieties, greatly contributed to yield increases associated with the green revolution. However, the semi-dwarf genotype was also associated with reduced inflorescence size. … Continue reading
