In mesophyll cells, carbonic anhydrase is mainly located in the chloroplast, however it is in the cytosol in plants with a C4 carbon concentrating mechanism. There is interest in relocating carbonic anhydrase to the cytosol of C3 plants as a first step in the introduction of a carbon concentrating mechanism.…

Domesticated crops provide a reliable food source but generally have little genetic diversity to cope with environmental fluctuations. By decrypting the genome of wild species such as the wild rice Oryza rufipogon, we may identify additional genetic variation useful for breeding process. However, the…

Polycarpic perennials, as opposed to annual plants, flower multiple times over several growing seasons throughout their lifecycle. To do that, they must retain a vegetative meristem that does not produce flowers during the reproductive phase. MADS-box transcription factors like FLOWERING LOCUS C (FLC)…

Nitric oxide (NO) acts as a signal molecule to regulate plant growth, from seed germination to floral formation. Female gametophyte (FG) development is sensitive to external signals; for example, in plants in adverse environements, a decrease in fertilizable FGs enhances the survival prospects of the…

Optimal temperatures for growth and development vary between plant species, making accurate temperature sensing crucial for their fitness. The search for molecular mechanisms underlying temperature signaling suggests that a single temperature sensor likely does not exist in plants. Instead, plants possess…

Rising sea levels and increasing salt accumulation in irrigated soils are threatening food production globally. There is a lot to be learned from plants that have evolved tolerance to salt. In this new preprint, Martínez-Rivas et al. explored the mechanism of salt tolerance the Cvi-0 accession of Arabidopsis…

Plants fix carbon dioxide to generate biomass, and in many cases increasing the availability of CO2 enhances plant growth. However, some studies have shown that although yields of food crops such as rice might increase, their nutritional value decreases, due to limitations in availability of minerals…

Host plants recognize diverse bacterial epitopes, known as microbe-associated molecular patterns (MAMPs), and respond with an immune reaction to control bacterial growth. However, most studies have focused on single bacterial epitopes, limiting our understanding of plant-bacteria interaction outcomes…
