Thale cress (Arabidopsis thaliana) has been the absolute star of plant science research for more than 40 years, being the ideal model organism for its ease of handling and transferable knowledge to crops. In this review, Cesarino and coworkers explain how advances in "omics" technologies, together with…

Conventional approaches to connect phenotype to genotype, including genome-wide association studies (GWAS), are often limited by the quality of the species’ reference genome, and frequently neglect to detect structural variants that are common in plant genomes. Here, Voichek and Weigel present a “No-Genome-Required-GWAS”…

The thylakoid membranes inside the chloroplasts house the major protein complexes required for photosynthesis, including photosystems I and II (PSI/II), the b6f complex and ATP synthase. To optimize photosynthetic efficiency, the distribution and abundance of these complexes are dynamically regulated…

Photosystem II (PSII) is a protein complex located in the thylakoid membrane of chloroplasts that is involved in executing the initial reaction of photosynthesis in plants. When plants are exposed to extreme temperature conditions, PSII gets damaged. To repair the damage, one of the core proteins of…

In this paper, Moreno et al. investigate how nitrate affects the balance between cell proliferation and cell expansion in shoots during early seedling development. They note that the cells in Arabidopsis cotyledons undergo considerable enlargement, and that the increase in cell size is correlated with…

Adjacent cells in plants are connected by cytoplasmic connections called plasmodesmata (PD) and the movement through PD is called symplastic movement. Studies have shown that auxin transport between cells is protein-dependent, but it is not clear whether it can also move freely in the symplastic pathway.…

Aquaporins, also known as plasma membrane intrinsic proteins (PIP), are a large group of transporters that facilitate water transport through membranes. In this article, Rahman et al. explored the role of aquaporins in the cold stress response. They found that two aquaporin genes, PIP1;4 and PIP2;5,…

Colonization of the terrestrial environment by land plants (embryophytes), a monophyletic clade that evolved from freshwater streptophyte algae, forever changed Earth by transforming biogeochemical cycles. The evolution of stomata was a key adaptation that allowed the colonization of terra firma. Present…
