Molecular advances in research and applications of male sterility systems in tomato.

Tomato, belonging to the nightshade family, is globally considered as a model system for classical and molecular genetics, genomics, and reproductive developmental studies. In the current scenario of climate change, hybrid development is among the crucial elements in the genetic improvement of crop plants. The phenomenon of male sterility is a viable approach for ensuring hybrid seed purity and reducing the cost of hybrid seed production.

Factors governing formation from methyl halogens and pseudohalogens.

The formation of following the double ionization of small organic compounds via a roaming mechanism, which involves the generation of H and subsequent proton abstraction, has recently garnered significant attention. Nonetheless, a cohesive model explaining trends in the yield of characterizing these unimolecular reactions is yet to be established. We report yield and femtosecond time-resolved measurements following the strong-field double ionization of CHX molecules, where X = OD, Cl, NCS, CN, SCN, and I.

Phyto-nutraceutical promise of Brassica vegetables in post-genomic era: a comprehensive review.

Brassica vegetables are one of the possible solutions to tackle the emerging human diseases and malnutrition due to their rich content of phyto-nutraceutaical compounds. The genomics enabled tools have facilitated the elucidation of molecular regulation, mapping of genes/QTLs governing nutraceutical compounds, and development of nutrient-rich Brassica vegetables. The enriched food products or foods as whole termed as functional foods are intended to provide health benefits.

Comparative evaluation of pit & fissure sealant retention using cotton roll & rubber dam isolation techniques - a systematic review & meta-analysis.

Background: Isolation with cotton rolls does not always provide as complete isolation as rubber dam, especially in procedures where absolute moisture control is critical. Therefore, this review aims to summarize and analyze previous studies evaluating the retention and marginal integrity of pit & fissure sealant using rubber dam and cotton roll isolation techniques during dental treatment in children.

Material And Methods: In accordance with PRISMA guidelines, search yielded 1361 articles, with seven RCTs and one non-RCT design meeting the inclusion criteria.

Deletion of both anaerobic regulator genes fnr and narL compromises the colonization of Salmonella Typhimurium in mice model.

Salmonella Typhimurium (STM), a zoonotic pathogen, can adjust its metabolic pathway according to the variations in the partial pressure of atmospheric oxygen and nitrate via fumarate nitrate reductase regulator (Fnr) and NarL, the response regulator for nitrate reductase. Both Fnr and NarL have been individually reported to be the contributors of virulent phenotypes of STM. Hypoxia along with nitrate-rich environment are prevalent in macrophages and the Salmonella-induced inflammatory lumen of the host's large intestine activates both fnr and narL genes.
