Genetic Parameters of Methane Emission, Feed Efficiency, Feeding Behaviour, and Growth Traits in Beef Cattle

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Climate change has intensified the need to reduce greenhouse gas emissions, particularly methane (CH4) from enteric fermentation. Genetic selection has emerged as a promising mitigation strategy; however, studies on Bos taurus indicus , especially Nellore cattle, remain limited.

Genotypic Variation and Association Mapping for Plant Stature and Anthesis‐Silking Interval in Set of Temperate‐Adapted Maize Lines Developed by DH and SSD Methods

open access: yesPlant Breeding, EarlyView.
ABSTRACT BS39 is a broad‐based population of tropical maize adapted to temperate environments that can provide useful and unique alleles to US Corn Belt breeding programmes. Doubled‐haploid (DH) has been used as an efficient alternative method to speed up the development of maize lines. Our objectives were to compare genetic parameters for plant height

Genetic divergence in cocoa progenies for backcrossing program to witches' broom disease resistance

open access: yesRevista Ceres, 2010
Backcrossing has been little used in cacao breeding, particularly due to the long time required to transfer genes and recover the genetic background of the recurrent parent.

Genomics and morphometry of herbarium specimens elucidate the origin of the Cape Verde date palm (Phoenix atlantica A.Chev.) and highlight its agronomic potential

open access: yesPLANTS, PEOPLE, PLANET, Volume 7, Issue 5, Page 1358-1371, September 2025.
As climate change accelerates, breeding resilient crops is urgent. The date palm (Phoenix dactylifera L.), a crucial 18 billion USD fruit crop, underpins North African and West Asian oasis agroecosystems. This study investigates the genetics and morphology of its closest wild relative, the endemic and endangered Cape Verde date palm (Phoenix atlantica ...

Reactive oxygen species act as signaling molecules to control root hair initiation and tip growth

open access: yesNew Phytologist, Volume 247, Issue 5, Page 2042-2048, September 2025.
Summary Root hairs (RHs) increase the surface area of roots, facilitating nutrient and water uptake and plant anchorage. RHs form from root epidermal cells and elongate by polar tip growth. Reactive oxygen species (ROS) have recently been implicated as important signals that drive RH formation and elongation using both genetic and imaging approaches ...
