Grasses fall into two clades, the more temperate BOP clade of C3 grasses (Bambusoideae, Oryzoideae, and Pooideae subfamilies), and the more tropical PACMAD clade of C3 and C4 grasses (Panicoideae, Arundinoideae, Chloridoideae, Micrairoideae, Aristidoideae, and Danthonioideae subfamilies). This review,…

Transgenerational memory can occur through epigenetic regulation of gene expression (for example through DNA methylation) when plants have been exposed to abiotic stresses. Transferring a specific biochemical adaption to the next generation of plants can help the plant counter stress. Here Xu et al.…

Calcium-dependent protein kinases (CDPKs/CPKs) are an interesting class of proteins present in plants, algae and some protists that are thought to “sense” and “respond” to spikes in intracellular Ca2+ signaling events. While multiple mechanisms have been proposed to be involved in the regulation…

The transition from aquatic to terrestrial habitats exposed plants to low water availability, high light, radiation, and other environmental challenges. To overcome these challenges, plants developed morpho-physiological adaptations to tolerate dry environments and make photosynthesis more efficient.…

Prions were first identified as the infectious protein agents causative of Creutzfeldt-Jakob disease or bovine spongiform encephalopathy (mad cow disease); when individuals eat something containing these prion proteins, the prion proteins induce conformational changes in their brains leading to neurological…

PHYTOCHROME INTERACTING FACTORS (PIFs) play a pivotal role in mediating the responses of plants to various environmental stimuli. Although the importance of PIFs in shade avoidance response is well known, the relative contributions of different PIFs have not been discretely determined. In a recent study,…

Increase in ambient temperature often causes remarkable changes in the shape and organization of plant body, including elongation of hypocotyl and petioles, early flowering, and reduction in stomatal index, collectively known as thermomorphogenesis. Virtually all the molecular pathways that are known…

Calcium ions (Ca2+) occupy a primary position in plant cell signaling processes by virtue of their role as the so-called second messengers. Ca2+ signaling underlies plant response to various abiotic, biotic and developmental cues. Whilst this Ca2+ signaling was thought to predominantly occur in the cytoplasm,…
