The flower is one of the most important organs of a plant as it provides fruits and seeds. Due to its economic value, flowers are studied extensively to understand its developmental process. Based on the popular ABC model of flower development, floral organ development is mostly regulated through the…

Phosphorylation and de-phosphorylation are fundamental events for signal transduction. Phytohormone and light signaling are no exception in this case. Plants face towards light by creating lateral auxin gradient between exposed and shaded sides. This asymmetric auxin distribution is mediated through…

Within cells there are vast numbers of different activities and processes occurring simultaneously. In eukaryotic cells, some of these processes are segregated into distinct membrane-bound compartments. Cuevas-Velazquez and Dinneny review how membraneless compartments also contribute to subcellular organization,…

Guest editor: Danielle Roodt Prinsloo Danielle is a PhD candidate in the Forest Molecular Genetics (FMG) Programme at the University of Pretoria, South Africa. She has been a Plantae Fellow since September 2017, having joined after attending her first ASPB Plant Biology meeting. Danielle is a plant…

The processing of the circadian clock requires that regulatory proteins are ubiquitinated and degraded, through their interactions with F-box proteins. Lee et al. used a decoy strategy to characterize the targets of three related F-box proteins involved in clock function, ZTL, LKP2 and FKF1, which genetic…

Obtaining the high yields needed to feed the human population depends on the application of nitrogen-containing fertilizers to non-leguminous crops, yet the production of these compounds consumes 1 – 2% of global energy output. Plant scientists are familiar with the conversion of  N2  to NH3 by nirogenase…

The three-dimensional arrangement of DNA within the nucleus clearly affects gene expression, but its contribution remains relatively unexplored as compared to other factors. Sotelo-Silveira et al. review new chromosome conformation capture (3C) and derived techniques for assessing genomes in 3D, as well…

Domestication of crop plants is intimately linked to the modulation of the plants circadian rhythms, allowing adaptation to new agricultural environments. Deceleration of the clock has been instrumental in tomato domestication; however the underlying molecular mechanisms are not fully understood. In…
