Defense heterosis as a novel plant protection strategy: From theory to breeding practice

New Plant Protection, EarlyView.
Defense heterosis, the enhanced disease resistance of hybrids compared to their parents, has evolved from early observations of hybrid vigor to a novel research concept. Advances are now clarifying its diverse genetic and molecular mechanisms across various plant–pathogen interactions.

Genome-Wide Identification and Characterization of Basic Pentacysteine Transcription Factors in Brassica napus

Plants
BARLEY B-RECOMBINANT/BASIC PENTACYSTEINE (BBR/BPC), a plant-specific transcription factor family, is a group of GAGA_motif binding factors controlling multiple developmental processes of growth and response to abiotic stresses.

HETEROSIS OR NEUTRALITY? [PDF]

Genetics, 1977
ABSTRACT Various statistics have been proposed on an ad hoc basis to test whether alleles at a locus are selectively neutral. By considering population models in which selection operates, this paper shows that the population homozygosity is a powerful test statistic for testing departures from neutrality, in the direction of heterozygote

Speciation with gene flow

PLANTS, PEOPLE, PLANET, EarlyView.
Biodiversity is threatened by human activities, with extinction debt accumulating rapidly. Many of these activities change the connectivity of populations, fragmenting existing population systems or bringing previously isolated populations or species into contact.

Comparative and phylogenetic study on the chloroplast genomes of CMS with the cytoplasm of Aegilops ovata and its maintainer line in wheat

BMC Genomics
Background  Aegilops ovata a wild relative of wheat. As a valuable genetic source, it can be used for wheat breeding and improvement. However, the interspecific variation, evolutionary mechanism and phylogenetic relationship of the chloroplast genome ...

Genomic Analysis of Taurine and Indicine Ancestry in the Montana Tropical Composite Population

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT The Montana Tropical cattle, a Taurine and Indicine composite, were developed in Brazil since 1994 and were based on crossing four biological types of cattle: zebu (mainly Nelore), tropical adapted taurine (mainly Senepol and Romosinuano), British taurine (mainly Angus) and continental taurine (as Charolais, Simental and Limousin).

Deletions linked to PROG1 gene participate in plant architecture domestication in Asian and African rice

Nature Communications, 2018
Plant architecture transition is one of the great consequences during rice domestication. Here, the authors find that chromosomal deletions linked to the previously known PROG1 gene also participate in plant architecture domestication in both Asian and ...

Genetic Evaluation of Beef Sires Using a Beef‐on‐Dairy Crossbred Reference Population

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT In recent years, Beef‐on‐Dairy (BoD) crossbreeding programs have gained momentum to enhance dairy cattle's economic and genetic merits while meeting the demand for high‐quality beef. However, bulls with superior growth potential can lead to calving problems; thus, Holstein dairy farmers must decide which semen to use to avoid calving problems ...

Natural variation of STKc_GSK3 kinase TaSG-D1 contributes to heat stress tolerance in Indian dwarf wheat

Nature Communications
Heat stress threatens global wheat (Triticum aestivum) production, causing dramatic yield losses worldwide. Identifying heat tolerance genes and comprehending molecular mechanisms are essential. Here, we identify a heat tolerance gene, TaSG-D1 E286K , in
