A next generation of studies: Heterosis and inbreeding depression

Next generation sequencing technologies and a sample of the most elite publicly available germplasm were used to explore the role of gene expression in hybrids vs. inbreds and found additive gene action to be the most prevalent among differentially expressed genes.

Transcriptome Resources For Function Analysis and Genetic Enhancement of Rice

Function of genes selected on the basis of transcriptome profiling has been demonstrated by using knock-out and over-expressing transgenics as well as gene mutants to provide direct proof of the function of gene and its utility for deployment in breeding programs.

Morpho Genetic Analysis And Exploitation Of Heterosis Among Hip Bearing Hybrid Roses

Results about pollen vigor parameters indicated that great variations in pollen quality, quantity, and viability and germination % ages are observed.

Comparative transcriptome analysis between inbred lines and hybrids provides molecular insights into K+ content heterosis of tobacco (Nicotiana tabacum L.)

Potassium (K+) is essential for crop growth. Increasing the K+ content can often directly promote the improvement of crop yield and quality. Heterosis plays an important role in genetic improvement

Overdominant expression of related genes of ion homeostasis improves K+ content advantage in hybrid tobacco leaves

Background Potassium(K + ) plays a vital role in improving the quality of tobacco leaves. However, how to improve the potassium content of tobacco leaves has always been a difficult problem in

Reciprocal recurrent selection based on genetic complementation: An efficient way to build heterosis in diploids due to directional dominance

Heterotic patterns can be developed quickly through genetic complementation surrogates to produce high-performance hybrids at a low cost in diploid species displaying dominance and boost GCA-based approaches in hybrid breeding.

Hybrid Vigour and Hybrid Mimics in Japonica Rice

In crop improvement programs, hybrid vigour (heterosis) is an important breeding strategy but the molecular mechanisms of hybrid vigour are still unclear. Grain yield declines after F1 generation due

Gene expression variation explains maize seed germination heterosis

There is faster imbibition and development in reciprocal crossing Zhengdan958 hybrids than in their parent lines during seed germination, providing evidence for the higher expression level genes in hybrid involved in metabolic pathways acting as main contributors to maize seed Germination heterosis.
