Tracking water transport to the host plants by arbuscular mycorrhizal fungi (New Phytol)

In spite of several years of observation of the symbiotic relationship between plants and arbuscular mycorrhizal fungi, we are still learning about the intricate mechanisms and processes behind their relationship. Symbiotic fungi provide nutrients (mainly phosphorus and nitrogen), stress tolerance, and water to the host plant in return for sugars and lipids. While there have […]

Plants’ PHR2-controlled phosphate starvation response regulates fungal symbiosis in rice (Nature Comms)

Plants’ interaction with microbes in the rhizosphere affects their health and productivity. Plant-arbuscular mycorrhiza (AM) fungi symbiosis is associated with almost 80% of land plants. The fungi provide phosphate, stress tolerance, and firmness to the soil in exchange for carbon. While low phosphate promotes AM symbiosis, the mechanistic basis of phosphate-dependent AM development remains obscure. […]

The splicing factor RNA BINDING PROTEIN 45d regulates temperature-responsive flowering (Plant Cell)

Posttranscriptional events such as splicing are part of the gene regulation toolbox. Previous studies have demonstrated a role for U-rich small nuclear ribonucleoproteins (snRNPs) such as U1 in the control of splicing. In a recent paper in The Plant Cell, Chang et al. identified a splicing factor, RNA BINDING PROTEIN 45d (RBP45d), in Arabidopsis, that […]

Extensive genome study to boost yield and improve agronomic traits in chickpea (Nature)

In recent years, there has been increasing awareness about the environmental impact of animal-based protein sources. Legumes such as chickpea (Cicer arientinum) are relatively cheap and sustainable sources of proteins, dietary fibres and micronutrients. Although there is a vast chickpea germplasm collection, little genomic characterization has been done. In Varshney et al., an international team […]

IRON MAN sequesters BTS to activate iron deficiency response (PNAS)

Plants need to maintain an optimum level of iron (Fe) for normal growth and development. Many Fe-responsive molecular players have been identified in Arabidopsis, including the IRON MAN (IMA) peptides. These peptides are induced by Fe deficiency, but their role in maintaining Fe homeostasis remains poorly understood. Li et al. provide a mechanistic insight into […]
