Zhang et al. show that GIF1 regulates the determinacy of meristems and controls tassel architecture in maize. The Plant Cell (2018). https://doi.org/10.1105/tpc.17.00791 Background: Plant architecture results from a balance of indeterminate and determinate cell fates. Cells with indeterminate fates…

Kurzbauer et al. discover a role for the Fanconi anemia D2 plant homogue in promoting meiotic crossover formation. https://doi.org/10.1105/tpc.17.00745 by Marie-Therese Kurzbauer and Peter Schlögelhofer Background: Meiosis is a specialized cell division and generates the basis for genetic diversity…

Feng et al. show that the transcription factor O11 is a master regulatory protein in endosperm development. Plant Cell https://doi.org/10.1105/tpc.17.00616. By Fan Feng and Rentao Song Background: Maize is one of the most important crops both for food and industry. The main nutrients of maize…

Plant growth and development consist of highly organized cellular patterns and depend on the directional growth and orientation of cells. Understanding microtubule dynamics is key to deciphering the formation of cellular shape and growth direction. In this research, Chakrabortty  et al. employed analytical…

Organogenesis is an essential process in embryonic development. Additionally, plants can generate new organs, such as roots, from postembryonic tissues utilizing postembryonic pathways. Bustillo-Avendaño and colleagues investigated de novo root formation from Arabidopsis thaliana leaf tissue. They…

In vascular development, procambial or cambial cells differentiate into xylem and phloem. In this research article, by using VISUAL (Vascular cell Induction culture System Using Arabidopsis Leaves) system, Saito et al. identified BES1 (BRI1 EMS SUPPRESSOR 1) as one of the components required for xylem…

The SAM (Shoot Apical Meristem) generates the cells that make up the shoot. In this paper, Landrein et al. studied how nutrient availability shapes SAM architecture. They showed that SAM size is positively correlated with both pTCSn::GFP (a cytokinin reporter) and pWUS::GFP (a major regulator for stem…

Embryogenesis is the simple process of plant development, but until recently our knowledge has been limited to how individual cells are specified and organized. Reported markers have been mostly constitutive promoter-driven, a fact that creates background and makes them unsuitable for the study of cellular…
