Maize Tassel Architecture
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…

Meiotic Crossover Formation
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…

A Unified Maize Endosperm Regulatory Network
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…

A computational framework for cortical microtubule dynamics in realistically shaped plant cells (PLOS Comp Biol)
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…

Regulation of postembryonic root organogenesis from Arabidopsis leaf tissue (Plant Physiol)
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…

BES1 and BZR1 redundantly promote phloem and xylem differentiation ($) (Plant Cell Physiol.)
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…

Nitrate modulates stem cell dynamics in Arabidopsis meristems through cytokinins ($) (PNAS)
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…

A toolkit for studying cellular reorganization during early Arabidopsis thaliana embryogenesis (Plant J.) ($)
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…

Transcriptomic analysis of wound xylem formation in Pinus canariensis (BMC Plant Biol.)
Woody plants, given their usually long life span, typically must face during their life several injuries that could take as long as several years to heal. In their work, Chano et al. use microarray analysis and RT-PCR to analyze the transcriptome changes that occurs during wood formation after a…
