One way to combat or treat breast cancer, the most common cancer among women, is to decrease or prevent proliferation of cancerous cells. Many animal species of agricultural importance have been selected for various growth traits, typically through altered proliferative capacity of some cell types. Previous studies in two lines of cattle divergently selected for serum IGF-I concentration have s...

BACKGROUND Understanding and managing the evolutionary responses of pests and pathogens to control efforts is essential to human health and survival. Herbicide-resistant (HR) weeds undermine agricultural sustainability, productivity and profitability, yet the epidemiology of resistance evolution - particularly at landscape scales - is poorly understood. We studied glyphosate resistance in a maj...

Landraces are key elements of agricultural biodiversity that have long been considered a source of useful traits. Their importance goes beyond subsistence agriculture and the essential need to preserve genetic diversity, because landraces are farmer-developed populations that are often adapted to environmental conditions of significance to tackle environmental concerns. It is therefore increasi...

Over the years, substantial gains have been made in locating regions of agricultural genomes associated with characteristics, diseases, and agroeconomic traits. These gains have relied heavily on the ability to statistically estimate the association between DNA markers and regions of a genome (quantitative trait loci or QTL) related to a particular trait. The majority of these advances have foc...

Food legumes play an important role in attaining both food and nutritional security along with sustainable agricultural production for the well-being of humans globally. The various traits of economic importance in legume crops are complex and quantitative in nature, which are governed by quantitative trait loci (QTLs). Mapping of quantitative traits is a tedious and costly process, however, a ...

One of the most evident elements of the agricultural crisis is farm abandonment in many marginal rural areas, such as mountains. Some traits of mountain agriculture such as remoteness, low productivity, extreme weather and small farm size, can limit the adaptation and the competitiveness of this branch. The analysis aims to assess the consumers’ Willingness to Pay (WTP) for permanence of the up...

The F1 hybrids along with the parents were evaluated in field for genetic analysis to determine the nature and magnitude of genetic variances and heritability estimates a in maize (Zea mays L.) in 2012 using RCBD with three replications. Results analysis of variance showed, based upon the results of tests, simple genetic model was fully adequate for analyzing the data set for all traits except ...

High yielding crop production technologies became available for farmers in irrigated favorable agricultural ecosystems from 1960’s known as Green Revolution, while 77% of world arable land (~1,086Mha in 2014, FAOSTAT) is estimated without irrigation and prone to water shortage or drought (a disaster from a shortage of rainfall and available water on agriculture and other human lives). Greater d...

in order to investigation of morphological traits, yield and its components in three cultivars of grain sorghum (kimia, sepideh, payam) and two promising lines (m5, m2) under four density (240000, 205000, 170000 and 135000 plant/m2), experiment was conducted as factorial design based on randomized complete block design with three replications in birjand agricultural research station, during 200...

Heritable epigenetic variants of genes, termed epialleles, can broaden genetic and phenotypic diversity in eukaryotes. Epialleles may also provide a new source of beneficial traits for crop breeding, but very few epialleles related to agricultural traits have been identified in crops. Here, we identified Epi-rav6, a gain-of-function epiallele of rice (Oryza sativa) RELATED TO ABSCISIC ACID INSE...
