I think one of the most important lessons a scientist learns is to cross-check their findings with a different approach in order to determine if the findings are reasonable. This interesting article by Oliveira-Filho and Campos-Silva et al. lays out several examples of using back-of-the envelope or Fermi calculations to “gauge reality”. The authors provide […]
Many bryophytes and other non-seed plants are tolerant to vegetative desiccation, which is thought to have been necessary for colonization of land. By contrast, most seed plants lack this capacity, although they retain desiccation tolerance in their pollen and seeds. However, some seed plants, known as resurrection plants, have re-evolved vegetative desiccation tolerance probably through […]
In this article by Haverroth et al., the authors explore plant-water dynamics in the shoot during and after waterlogging, using as a model Phaseolus vulgaris, which is particularly sensitive to waterlogging. One of the interesting findings is that early after waterlogging and prior to leaf dehydration, stomatal pores close and leaf hydraulic conductivity declines; the […]
Review: Root development and symbiosis: an epigenetic perspective Roots do not grow in isolation but occupy a space inhabited by a variety of organisms. With certain fungi and bacteria, they form partnerships or symbiotic relationships that increase the plant’s nutrient uptake and assimilation. While the knowledge on the genetic programs required to establish these symbiotic […]
Sydney Brenner famously said, “Progress in science depends on new techniques, new discoveries and new ideas, probably in that order.” Right now, we’re seeing how advancements and new techniques in artificial intelligence and deep learning are being applied in plant sciences, including in the analysis of all sorts of large -omics datasets. This review by […]
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 that is sourced from the Cape Verde […]
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 such as iron and zinc. In this study by […]
Review: Deep learning approaches to understanding stomatal function Sydney Brenner famously said, “Progress in science depends on new techniques, new discoveries and new ideas, probably in that order.” Right now, we’re seeing how advancements and new techniques in artificial intelligence and deep learning are being applied in plant sciences, including in the analysis of all […]
Plant immunity is beautifully sophisticated with a ever-growing cast of characters. This review by Liu et al. focuses on the contributions of proteolysis (protein degradation), which both activates and suppresses immune responses. The authors structure the review around four key functions of proteolysis: direct degradation of pathogen proteins, activation of host immune proteins, regulation of […]
