Bananas are among the most important fruit crops worldwide, being cultivated in more than 120 countries, mainly by small-scale producers. However, short-stature high-yielding bananas presenting good agronomic characteristics are hard to find. Consequently, wind continues to damage a great number of plantations each year, leading to lodging of plants and bunch loss. Development of new culti...
*Corresponding Author Rajesh. K. Patel [email protected] The present study investigated the occurrence of an autosomal recessive genetic disease, Bovine Citrullinaemia caused by mutation in Argininosuccinate Synthase (ASS) gene, in Indian Holstein cattle. The Polymerase chain reactionRestriction fragment length polymorphism (PCR-RFLP) analysis was performed on a group of 120 Holstein bulls to...
Barley has been cultivated for more than 10,000 years. Barley improvement studies always have the privilege of the breeders and scientists. This review is expected to provide a resource for researchers interested in barley improvement research in terms of mutation breeding, tissue culture, gene transfers, gene editing, molecular markers, transposons, epigenetic, genomic studies and system biolo...
Selective breeding has strongly reduced the genetic diversity in livestock species, and contemporary breeding practices exclude potentially beneficial rare genetic variation from the future gene pool. Here we test whether important traits arising by new mutations can be identified and rescued in highly selected populations. We screened milks from 2.5 million cows to identify an exceptional indi...
We present Propulate, an evolutionary optimization algorithm and software package for global in particular hyperparameter search. For efficient use of HPC resources, Propulate omits the synchronization after each generation as done conventional genetic algorithms. Instead, it steers search with complete population at time breeding new individuals. provide MPI-based implementation our algorithm,...
Mutation breeding is the defined approach used for crop production and has played a key role in creation of several varieties. The present research was carried out to induce mutants kodo millet variety CO 3 using physical mutagen (gamma rays) chemical (Ethyl Methane Sulphonate) creating novelty. Seeds were treated with five doses gamma-rays viz., 100 Gy, 200 300 400 500 Gy at BARC, Kalpakam thr...
N0-ethyl-N0-nitrosourea (ENU) is a powerful germline mutagen used in conjunction with phenotype-driven screens to generate novel mouse mutants. ENU also induces genetic lesions in somatic cells and dosage requires optimization between maximum germline mutation rate versus induced sterility and tumourigenesis that compromise the welfare and fecundity of the ENUtreated males. Here, we present our...
N'-ethyl-N'-nitrosourea (ENU) is a powerful germline mutagen used in conjunction with phenotype-driven screens to generate novel mouse mutants. ENU also induces genetic lesions in somatic cells and dosage requires optimization between maximum germline mutation rate versus induced sterility and tumourigenesis that compromise the welfare and fecundity of the ENU-treated males. Here, we present ou...
Salt stress is a complex physiological trait affecting plants by limiting growth and productivity. Rice, one of the most important food crops, is rated as salt-sensitive. High-throughput screening methods are required to exploit novel sources of genetic variation in rice and further improve salinity tolerance in breeding programmes. To search for genotypic differences related to salt stress, we...
Bovine Leucocyte Adhesion Deficiency (BLAD) is a Holstein-Friesian HF) specific autosomal recessively inherited disorder characterized by recurrent pneumonia, ulcerative and granulomatous stomatitis, enteritis, periodontitis, loss of teeth, delayed wound healing, persistent neutrophilia and death at an early age [1]. BLAD is a disease characterized by a reduced expression of the adhesion molecu...
