An oxalate decarboxylase-like cupin domain containing protein is involved in imparting acid stress tolerance in Bacillus amyloliquefaciens MBNC.

We report here the structural and functional properties of an oxalate decarboxylase (OxDC)-like cupin domain-containing protein of Bacillus amyloliquefaciens MBNC and its role in imparting tolerance to acid stress conditions. Quantitative real-time PCR (qPCR) analysis revealed 32-fold and 20-fold upregulation of the target gene [(OxDC')cupin] under acetic acid stress and hydrochloric acid stress, respectively, indicating its association with the acid stress response. Bacterial cells with targeted inactivation of the (OxDC')cupin gene using the pMUTIN4 vector system showed decreased growth and survival rate in acidic pH, with drastically reduced exopolysaccharide production.

Assessment of MMP14, CAV2, CLU and SPARCL1 expression profiles in endometriosis.

Endometriotic cells exhibit a notable degree of invasiveness and some characteristics of tissue remodeling underlying lesion formation. In this regard, do matrix metalloproteinases 14 (MMP14) and other related genes such as SPARC-like protein 1 (SPARCL1), caveolin 2 (CAV2), and clusterin (CLU) exert any significant influence in the processes of endometriosis development and pathophysiology is not apparent. We aim to assess whether these genes could serve as potential diagnostic biomarkers in endometriosis.

Evaluation of water hyacinth utility through geospatial mapping and in situ biomass estimation approach: a case study of Deepor beel (wetland), Assam, India.

As an invasive species, water hyacinths (Eichhornia crassipes) are known to progressively proliferate and cause the ecological invasions of the aquatic environment. The incursions of the water hyacinths not only cause the disappearance of native species but gradually degrade the natural habitats of freshwater regimes. The control and management of these species are laborious task; however, transforming weed into wealth can substantially serve a sustainable approach to reduce the efforts.

The Potential of Mutant in Maize ( L.): A Sustainable Solution to Non-Renewable Phosphorus.

Background: Phosphorus is an essential component of fertilizers and feed and in recent decades has become one of the main sustainability issues as a non-renewable resource. In plant seeds, the main reserve of phosphorus is phytic acid, a strong anti-nutritional factor for monogastrics and a pollutant of cultivated lands. The reduction of phytic acid in cereal seeds has become a major challenge in breeding programs to increase the nutritional quality of foods and feeds and to improve the environmental phosphorus sustainability in agriculture.

Molecular mapping of drought-responsive QTLs during the reproductive stage of rice using a GBS (genotyping-by-sequencing) based SNP linkage map.

Background: In rice, drought stress at reproductive stage drastically reduces yield, which in turn hampers farmer's efforts towards crop production. The majority of the rice varieties have resistance genes against several abiotic and biotic stresses. Therefore, the traditional landraces were studied to identify QTLs/candidate genes associated with drought tolerance.
