Use of historical data improves early selection in a public rice breeding program

open access: yesCrop Science, Volume 65, Issue 6, November/December 2025.
Abstract Increasing selection accuracy for parental lines in the early stages of a breeding program can significantly shorten the breeding cycle and accelerate genetic gain. Public breeding programs have limited resources, which in many cases implies not having enough funds for genomic selection.

Improving Genomic Prediction Using High‐Dimensional Secondary Phenotypes: The Genetic Latent Factor Approach

open access: yesBiometrical Journal, Volume 67, Issue 5, October 2025.
ABSTRACT Decreasing costs and new technologies have led to an increase in the amount of data available to plant breeding programs. High‐throughput phenotyping (HTP) platforms routinely generate high‐dimensional datasets of secondary features that may be used to improve genomic prediction accuracy.

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 ...

A comprehensive review of the genetic control of cooking time in dry beans (Phaseolus vulgaris L.)

open access: yesPLANTS, PEOPLE, PLANET, Volume 7, Issue 4, Page 934-953, July 2025.
Reducing cooking time could increase dry beans (Phaseolus vulgaris) consumption. Cooking is an essential processing step needed to unlock the nutrients in dry beans and to make them palatable and safe for consumption. Long cooking times have consequences for dry bean use, especially where cooking fuel cost is high and when people prefer foods that are ...

Young maize plants impact the bacterial community in Australian cotton‐sown vertisol more than agricultural practices

open access: yesEnvironmental Microbiology Reports, Volume 17, Issue 3, June 2025.
In an irrigated Vertisol, different cotton farming systems affected only a few bacterial groups and potential metabolic functions. However, the application of maize plants or their neutral detergent fibre fraction had a significant impact on many of them. Abstract Changes in soil characteristics due to varying farming practices can modify the structure
