Multi-locus genome wide association study uncovers genetics of fresh seed dormancy in groundnut.

BMC Plant Biol

December 2024

Center of Excellence in Genomics & Systems Biology (CEGSB) and Centre for Pre-breeding Research (CPBR), International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), Hyderabad, 502324, India.

Pre-harvest sprouting (PHS) in groundnut leads to substantial yield losses and reduced seed quality, resulting in reduced market value of groundnuts. Breeding cultivars with 14-21 days of fresh seed dormancy (FSD) holds promise for precisely mitigating the yield and quality deterioration. In view of this, six multi-locus genome-wide association study (ML-GWAS) models alongside a single-locus GWAS (SL-GWAS) model were employed on a groundnut mini-core collection using multi season phenotyping and 58 K "Axiom_Arachis" array genotyping data.

In this study, we unveil a highly enantioselective [3 + 2] annulation protocol, adept at merging -2,2,2-trifluoroethylisatin ketimines with 3-alkylidene benzofuranones under quinine-derived urea catalysis. This strategy furnishes complex spiro[benzofuran-pyrrolidine]indolinedione architectures, featuring strategically positioned trifluoromethyl groups of considerable pharmacological significance. The method distinguishes itself by employing minimal catalyst loadings while ensuring energy efficiency and accommodating a broad spectrum of substrates, resulting in excellent yields and exceptional stereocontrol (38 examples, up to 98% yield, up to >20 : 1 dr, and up to 99 : 1 er).

Stunting among children is a reflection of the chronic malnutrition caused by a complex set of behavioural, demographic, and socioeconomic factors. This long-term detrimental exposure to chronic malnutrition is disproportionately higher among social and economically deprived groups, leading to significant differentials in the prevalence of stunting across various social strata. Therefore, this study investigates the inequality of social groups in terms of the prevalence of stunting across Schedule Caste (SC)-Scheduled Tribe (ST) and non-SC-ST.

Glutathione (GSH) and its oxidized dimer (GSSG) play an important role in living systems as an antioxidant, balancing the presence of reactive oxygen species (ROS). The central thiol (-S-S-) bond in GSSG can undergo free rotation, providing multiple conformations with respect to the S-S bridge. The six titratable sites of GSSG, which are influenced by pH variations, affect these conformations in solution, whereas in solids, additionally crystal packing effects come into play.

Background: Modern psychological research challenges the conventional view of stress as solely detrimental by introducing the concept of eustress versus distress, emphasizing the potentially positive aspects of stress. In the context of India, limited studies have investigated the distinct effects of eustress and distress on adolescents, a group prone to stress-related health issues. This study aims to bridge this gap by examining the correlation between eustress and both mental and physical well-being among adolescents attending government schools in two districts of Haryana, India.

The accurate detection of Protamine and Trypsin, two biomolecules with significant clinical and biological relevance, presents a substantial challenge because of their structural peculiarities, low abundance in physiological fluids, and potential interference from other substances. Protamine, a cationic protein, is crucial for counteracting heparin overdoses, whereas Trypsin, a serine protease, is integral to protein digestion and enzyme activation. This study introduces a novel fluorescence sensor based on a (4-(1,2,2-tris(4-phosphonophenyl)vinyl)phenyl)phosphonic acid octasodium salt (TPPE), leveraging aggregation-induced emission (AIE) characteristics and electrostatic interactions to achieve selective and sensitive detection of these biomolecules.
