Fungal exopolysaccharide regulates plant-microbe interaction (Plant Cell)

The studies on the apoplastic interactions of plants and fungi often focus on the fungal cell-wall, but recent studies indicate various plant colonizing fungi also have an exopolysaccharide (EPS) layer outside their cell wall. Chandrasekar et al. observed that the composition of this fungal EPS is distinct from the fungal cell wall and the secreted […]

The urban environment led to unintended adaptive evolution in plants (Science)

Generally, evolution is driven by natural selection, but not always. Human activities lead to the creation of unique niches, and other organisms must adapt accordingly. Cities are unique niches that are significantly different from rural areas and natural conditions. The urban habitat provides plants with adequate water and protection from herbivores. In a recent study, […]

MAP kinase cascade acts as a hub to decide the ways to fight infection (Sci. Adv.)

Much of our understanding of plant immunity comes from studies of pathogens that infect mesophyll tissues, (e.g., Pseudomonas syringae). However, there are many pathogens that specifically invade vascular tissues (e.g., Xanthomonas oryzae pv. oryzae; Xoo), which causes rice bacterial blight. In a recent report by Lin et al., the authors detected a signaling cascade that […]

How many tree species are there? (PNAS)

Do you know how many tree species are there? The global Forest Biodiversity Initiative (GFBI) database has annotated about 28,000 tree species, while some studies indicate there could be around 60,000. But why this difference? Many of the species are found in unapproachable areas. Additionally, human errors such as giving different names to the same […]

Crosstalk between phosphate transport and plant immunity (Curr. Biol.)

Plants have evolved signaling cascades to survive biotic and abiotic stresses, and recent studies have shown that there is crosstalk between many of these pathways.  In a recent study, Dindas et al. developed a micro-electrode-based system to detect active inorganic phosphate (Pi) transport in Arabidopsis seedlings in real-time. Pi transport can be observed as membrane […]
