Optimal stomatal regulation is important for plant adaptation to changing environmental conditions and for maintaining crop yield. The guard-cell signal GABA is produced from glutamate by Glutamate Decarboxylase (GAD) during a reaction that generates carbon dioxide (CO ) as a by-product. Here, we investigated a putative connection between GABA signalling and the more clearly defined CO signalling pathway in guard cells.

1 Introduction Arabinogalactan-proteins (AGPs) are glycoproteins that have been identified in cell walls of plant and algal species and encoded by large and diverse multigene families. A feature that defines AGPs are arabinogalactan (AG) glycomotif sequences that direct addition of type II AG glycan chains O-linked to hydroxyproline (Hyp) in the protein backbone.

Abstract Seeds are a vital source of calories for humans and a unique stage in the life cycle of flowering plants. During seed germination, the embryo undergoes major developmental transitions to become a seedling. Studying gene expression in individual seed cell types has been challenging due to the lack of spatial information or low throughput of existing methods. To overcome these limitations, a spatial transcriptomics workflow was developed for germinating barley grain.
