Not AvailableThe experiment was conducted to evaluate the native phosphate solubilizing fungi on inorganic phosphate solubilization in the acidic soils of Jharkhand, India. Mineral phosphate solubilizing activities of three fungal isolates were tested in tricalcium phosphate and ferric phosphate medium by analyzing the possible phosphorus release and phosphatase activity from 5th, 10th and 15th day of incubation. Maximum P release was observed on 5th and 10th day of incubation in ferric phosphate and tricalcium phosphate medium, respectively, by all the isolates. Among the isolates, Aspergillus niger induced highest P release of 635 and 695 μg ml-1 and resulted in 75 and 77% P solubilisation in tricalcium phosphate and ferric phosphate medium, respectively. The pH of the culture filtrate medium gradually decreased with the progress of incubation and maximum decrease was observed between 5- 10th day of incubation by all the fungal species. The highest peak of acid phosphatase activity in culture filtrates of fungal isolates were observed on 5th and 10th day of incubation in ferric phosphate and tricalcium phosphate medium, respectively. The highest acid phosphatase activity of 73 U was induced both by Aspergillus niger and Trichoderma viride in tricalcium phosphate medium. However, the highest acid phosphatase activity in ferric phosphate medium was 51 U induced by A. niger. Among the isolates, A. niger was more efficient in solubilising the inorganic P followed by T. viride and Penicillium chrysogenum.Not Availabl

Occurrence, Impact on Agriculture, Human Health, and Management Strategies of Zearalenone in Food and Feed: A Review

Mycotoxins represent an assorted range of secondary fungal metabolites that extensively occur in numerous food and feed ingredients at any stage during pre- and post-harvest conditions. Zearalenone (ZEN), a mycotoxin categorized as a xenoestrogen poses structural similarity with natural estrogens that enables its binding to the estrogen receptors leading to hormonal misbalance and numerous reproductive diseases. ZEN is mainly found in crops belonging to temperate regions, primarily in maize and other cereal crops that form an important part of various food and feed. Because of the significant adverse effects of ZEN on both human and animal, there is an alarming need for effective detection, mitigation, and management strategies to assure food and feed safety and security. The present review tends to provide an updated overview of the different sources, occurrence and biosynthetic mechanisms of ZEN in various food and feed. It also provides insight to its harmful effects on human health and agriculture along with its effective detection, management, and control strategies

Marker-Assisted Introgression of Saltol QTL Enhances Seedling Stage Salt Tolerance in the Rice Variety “Pusa Basmati 1”

Marker-assisted selection is an unequivocal translational research tool for crop improvement in the genomics era. Pusa Basmati 1 (PB1) is an elite Indian Basmati rice cultivar sensitive to salinity. Here, we report enhanced seedling stage salt tolerance in improved PB1 genotypes developed through marker-assisted transfer of a major QTL, Saltol. A highly salt tolerant line, FL478, was used as the Saltol donor. Parental polymorphism survey using 456 microsatellite (SSR)/QTL-linked markers revealed 14.3% polymorphism between PB1 and FL478. Foreground selection was carried out using three Saltol-linked polymorphic SSR markers RM8094, RM493, and RM10793 and background selection by 62 genome-wide polymorphic SSR markers. In every backcross generation, foreground selection was restricted to the triple heterozygotes of foreground markers, which was followed by phenotypic and background selections. Twenty-four near isogenic lines (NILs), with recurrent parent genome recovery of 96.0–98.4%, were selected after two backcrosses followed by three selfing generations. NILs exhibited agronomic traits similar to those of PB1 and additional improvement in the seedling stage salt tolerance. They are being tested for per se performance under salt-affected locations for release as commercial varieties. These NILs appear promising for enhancing rice production in salinity-affected pockets of Basmati Geographical Indication (GI) areas of India
