Untangling complexity: shedding a new light on LEAFY and APETALA1 interactions
by Leonie Verhage and Francois Parcy Institut de Biosciences et Biotechnologies de Grenoble (France) Ever since their discovery almost 30 years ago, the transcription factors LEAFY (LFY) and APETALA1 (AP1) (together with its paralog CAULIFLOWER (CAL)) have been extensively studied for … Continue reading
Spatially resolved floral transcriptome profiling
by Alt-Jan Van Dijk Plant Research International, Wageningen University Progress in sequencing technology has had a clear impact on flowering research. For example, ChIP-seq has been applied to study molecular aspects of transcriptional regulation of flowering. Also, RNA-seq data for … Continue reading
A miraculous mirabilis: the gymnosperm Welwitschia provides new insights into the origin of flowers
by Frank Wellmer Smurfit Institute of Genetics, Trinity College Dublin, Ireland The specification of male and female reproductive organs in gymnosperms and angiosperms is thought to be remarkably similar and to depend on the activities of B and C class … Continue reading

Focusing on TERMINAL FLOWER 1 (TFL1) regulation
by Timo Hytönen University of Helsinki, Finland FLOWERING LOCUS T (FT) and TERMINAL FLOWER 1 (TFL1) are small closely related proteins that have a great impact on the production of agricultural and horticultural crops and forest trees. FT functions as … Continue reading

A new comparative approach to understand local adaptation
Martin Lascoux Department of Ecology and Genetics, Uppsala University This is a flowering highlight that only indirectly concerns flowering. Furthermore the study does not address the molecular basis of flowering as is often the case in these columns but instead … Continue reading
New insights into LEAFY structure and function
by Frank Wellmer Smurfit Institute of Genetics, Trinity College Dublin, Ireland The plant-specific transcription factor LEAFY (LFY) is a master regulator of early flower development (Weigel et al., 1992). It orchestrates the onset of flowering and is involved in activating … Continue reading

The interactions they are a changin’ – The complex role of protein interactions in the evolution of flower development
by Aalt-Jan Van Dijk Among the various transcription factors involved in regulating flowering, no doubt MADS domain proteins involve some of the best studied. B-class proteins are a specific type of MADS domain proteins, named after their role in the … Continue reading

Is the cold gone? – Many roads to flowering after winter
Lars Hennig Swedish University of Agricultural Sciences, Department of Plant Biology & Linnean Center for Plant Biology, PO-Box 7080, SE-75007 Uppsala, Sweden Strolling through gardens and nature in March, one sees signs of spring everywhere. It is less the fresh green … Continue reading
More than the (human) eye can see: the regulation of floral UV absorbance
Beverley Glover Department of Plant Sciences, University of Cambridge, Cambridge CB2 3EA, UK. bjg26@cam.ac.uk Flowers come in many different colours, and those colours can be arranged in a wide variety of patterns. Colour itself arises from a combination of differential … Continue reading
