Heterosis is prevalent for multiple traits in diverse maize germplasm.

PLoS ONE, 2009
BackgroundHeterosis describes the superior phenotypes observed in hybrids relative to their inbred parents. Maize is a model system for studying heterosis due to the high levels of yield heterosis and commercial use of hybrids.MethodsThe inbred lines ...

Impact of Model Parameterisation and Variance Component Estimates on Genomic Predictions of Carcass Traits in Montana Composite Cattle

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT This study evaluated the influence of variance component (VC) estimates, obtained from different models and two relationship matrices, pedigree‐based (BLUP) and genomic information‐based (ssGBLUP), on genomic predictions of carcass traits in Montana composite cattle.

Genome-wide identification and expression analysis of the kinesin gene superfamily suggests roles in response to abiotic stress and fertility of wheat (Triticum aestivum L.)

BMC Genomics
Background Kinesin is a motor for microtubule-based motility. It plays a vital role in plant growth and development. The kinesin superfamily members are known mainly from Arabidopsis.

Structural and developmental insights into the muscles involved in lionfish (Pterois spp.) vocalisations

Journal of Fish Biology, EarlyView.
Abstract Vocal signalling is an important mode of communication in fishes. The two species of lionfish in the Pterois complex, the Indo‐Pacific lionfish (Pterois volitans) and the red lionfish (Pterois miles), are both known to produce different types of sounds with sonic muscles attached to the swimbladder.

Heterosis in crop improvement

The Plant Journal, 2023
SUMMARYHeterosis, also known as hybrid vigor, is the phenomenon wherein a progeny exhibits superior traits relative to one or both parents. In terms of crop breeding, this usually refers to the yield advantage of F1 hybrids over both inbred parents. The development of high‐yielding hybrid cultivars across a wider range of crops is key to meeting future

TaTCP6 is required for efficient and balanced utilization of nitrate and phosphorus in wheat

Nature Communications
High crop yields require adequate nutrients, particularly nitrate (N) and phosphorus (P). Identifying regulators for efficient N-P utilization is critical in wheat.

Physio-Morphological Characters of F1 Hybrids of Rice (Oryza sativa L.) in Japonica-Indica Crosses

Plant Production Science, 2001
A pot experiment was conducted to study photosynthetic rate in terms of carbon dioxide exchange rate (GER), chlorophyll meter reading (SPAD value) and specific leaf area (SLA) of 12 Fj hybrids from crosses between japonica and indica rice and their ...

Hierarchical additive effects on heterosis in rice (Oryza sativa L.)

Frontiers in Plant Science, 2015
Exploitation of heterosis in crops has contributed greatly to improvement in global food and energy production. In spite of the pervasive importance of heterosis, a complete understanding of its mechanisms has remained elusive.

The Pitfalls of Heterosis Coefficients

Plants, 2020
Heterosis (hybrid vigour) is a universal phenomenon of crucial agro-economic and evolutionary importance. We show that the most common heterosis coefficients do not properly measure deviation from additivity because they include both a component ...
