People have long assumed that wheels evolved from simple wooden rollers. But how? And why? A new model focused on mechanical advantage and structural strength suggests some answers.

Cammarata et al. explore how cell division orientation generates phyllotaxis in moss with a unicellular meristem. They show that successive rotational divisions in the apical cell are precisely placed...

From tiny mosses to giant redwoods, around 450,000 species of land plants show a huge variety of forms, yet all land plants develop from stem cells in proliferative meristems. What makes a meristem? T...

Plants display a wide range of life spans and aging rates. Although dynamic changes to DNA methylation are a hallmark of aging in mammals, it is unclear whether similar molecular signatures reflect ra...

Vincent Cerbantez-Bueno, elected as a NAASC Early Career Scholar in 2024, interviews former NAASC faculty member Adrienne Roeder about her career: her background and personal journey to becoming a pla...

Inflorescences of flowering plants adopt diverse genetically programmed and environmentally tuned architectures. By contrast, continued maintenance of the stem-cell pool within the apical meristem is ...

Author summary In eukaryotes, DNA is tightly associated with histone proteins. Histone covalent modifications and histones isoforms, also called histone variants provide most of the complexity of chro...

Single-molecule tracking of transcription factors in living cells revealed how mutations that make short activation domains stronger increased the fraction of transcription factor molecules bound to chromatin and led to longer residence times on chromatin.

Conformational biasing (CB) is a rapid and streamlined computational method that uses contrastive scoring by inverse folding models to predict protein variants biased toward desired conformational sta...

Spatially resolved gene expression during barley development was done by integrating an scRNA-seq dataset from cells with unknown position with spatial transcriptomics. This dataset is publicly availa...

Fewer outsiders, less feedback, and an uncertain fate for a new science board report

Abstract. The growing availability of genomes from non-model organisms offers new opportunities to identify functional loci underlying trait variation thro

In plants, the development of the shoot vascular system is closely coordinated with lateral organ formation at the shoot apical meristem. Despite exte…

An analysis of AlphaFold protein structure predictions shows that while in many cases the predictions are highly accurate, there are also many instances where the predicted structures or parts of pred...

The Polycomb Repressive Complex 2 (PRC2) is an ancient, conserved chromatin-interacting complex that controls gene expression, facilitating differentiation and cellular identity during development. It...
