RORA (RAR-Related Orphan Receptor Alpha) regulates estrogen synthesis by transcribing steroid related genes. Litter size is an important reproductive trait associated with synthesis. Therefore, it critical to investigate the relationship between gene and sheep litter size. In this study, a 23 base pair nucleotide sequence mutation in called effect of on productivity offspring were investigated....

mutation induction is considered as an effective way to enrich plant genetic variation, particularly fortraits with a very low level of genetic variation. this research was conducted to assess genetic variationinduced by gamma radiation in m2 and m3 mutant lines of canola (brassica napus l.) by ssr and morphologicalcharacteristics and to identify useful mutants in terms of agronomic traits. six...

The mutation pattern of immunoglobulin genes was studied in mice deficient for DNA polymerase eta, a translesional polymerase whose inactivation is responsible for the xeroderma pigmentosum variant (XP-V) syndrome in humans. Mutations show an 85% G/C biased pattern, similar to that reported for XP-V patients. Breeding these mice with animals harboring the stop codon mutation of the 129/Olain ba...

A T→A mutation in the promoter region of porcine myostatin (MSTN) gene has been identified in our previous work. This study analyzed the associations of the myostatin genotypes (TT, TA) caused by this mutation with birth weigh in Yorkshire pigs. Data from 211 unrelated individuals were collected three times from one breeding farm. Detections of the mutation were carried out by PCR-RFLPs approac...

Fruit and vegetable crops are rich in dietary fibre, vitamins minerals, which vital to human health. However, many biotic stressors (such as pests diseases) abiotic threaten crop growth, quality, yield. Traditional breeding strategies for improving traits include a series of backcrosses selection introduce beneficial into fine germplasm, this process is slow resource-intensive. The new techniqu...

Sugarcane is a major crop for sugar production around the world. The complexity of sugarcane genome creates challenges use both conventional and molecular breeding methods to improve at genetic level. DNA sequencing an important tool assess how genus Saccharum genera complex are interrelated. Here, we identify kinship Nepal2013-6 (Saccharum spontaneum, x = 10) using tetra-primer amplification r...

Genetic variation is needed for developing new superior varieties in plant breeding. of chili plants could be increased by inducing mutation with gamma rays irradiation. The aim this study was to determine radiosensitivity two local pepper calculating the lethal dose values at LD20 and LD50. Chili (Capsicum frutescens L.) seeds origin from Tulungagung Ponorogo were irradiated cobalt-60 doses of...

We present a new tierra-inspired artiicial life system with local interactions and two-dimensional geometry , based on an update mechanism akin to that of 2D cellular automata. We nd that the spatial geometry is conducive to the development of diversity and thus improves adaptive capabilities. We also demonstrate the adaptive strength of the system by breeding cells with simple computational ab...
