A network comprising ELONGATED HYPOCOTYL 5, microRNA397b, and auxin-associated factors regulates root hair growth in Arabidopsis.

ELONGATED HYPOCOTYL 5 (HY5) is a major light-associated transcription factor involved in plant growth and development. In Arabidopsis (Arabidopsis thaliana), the role of HY5 is very well defined in regulating primary root growth and lateral root formation; however, information regarding its role in root hair development is still lacking, and little is known about the genetic pathways regulating this process. In this study, we investigated the role of HY5 and its associated components in root hair development.

Firecracker Powder: A Unique Source of Burn Injuries.

Firecrackers are a common cause of burns in India; large-scale use of firecrackers is seen during the festival of Diwali, and patients of all age groups present with varying patterns of firecracker burns. With the recent ban of firecrackers in some parts of the country, we have noticed a new emerging cause of burns during Diwali where patients were attempting to prepare firecrackers at home using (sulfur) and potash by mixing the materials in a pipe gun. Explosion of this powder leads to varying degree of burns, and this series reports 12 such cases who presented to a tertiary care burn unit in North India during the 2022 festival of Diwali.

A citrate efflux transporter important for manganese distribution and phosphorus uptake in rice.

The plant citrate transporters, functional in mineral nutrient uptake and homeostasis, usually belong to the multidrug and toxic compound extrusion transporter family. We identified and functionally characterized a rice (Oryza sativa) citrate transporter, OsCT1, which differs from known plant citrate transporters and is structurally close to rice silicon transporters. Domain analysis depicted that OsCT1 carries a bacterial citrate-metal transporter domain, CitMHS.

Monogalactosyl diacylglycerol synthase 3 affects phosphate utilization and acquisition in rice.

Galactolipids are essential to compensate for the loss of phospholipids by 'membrane lipid remodelling' in plants under phosphorus (P) deficiency conditions. Monogalactosyl diacylglycerol (MGDG) synthases catalyse the synthesis of MGDG which is further converted into digalactosyl diacylglycerol (DGDG), later replacing phospholipids in the extraplastidial membranes. However, the roles of these enzymes are not well explored in rice.
