چکیده

Although heterosis is widely utilized in crop production, its genetic and molecular basis is still elusive. It is arguably that heterosis arises in crosses between genetically and/or epigenetically distinct individuals. Various genetic models have been proposed to explain heterosis, such as dominance and overdominance hypothesis. With the recent advancements in functional genomics, epigenetics, transcriptomics, proteomics, and metabolomics-related technologies, systems-level approaches have been adopted to understand the molecular basis of heterosis. In this review, we gather a brief account of findings from various studies in order to better understand the genetic and molecular basis of heterosis.

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

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. In this study, a small test-crossed rice population was constructed to investigate the formation mechanism of heterosis for 13 traits. The results of the relative mid-pa...

The pure-line hybrid concept traces its roots back to experiments on heterosis and its complement in- breeding conducted by SHULL (1908, 1909) at Cold Spring Harbor Laboratories in New York, and EAST

Today the concept of heterotic groups and patterns is fundamental to hybrid breeding theory and practice. Our objectives were to (i) review various hypotheses on the causes of heterosis in maize and on the experimental evidence supporting or refuting them, (ii) examine advantages and disadvantages of the concept of heterotic groups and patterns, (iii) describe the status of heterotic patterns i...

Heterosis in rice seedlings: its relationship to gibberellin content and expression of gibberellin metabolism and signaling genes.

Despite the accumulation of data on the genetic and molecular understanding of heterosis, there is little information on the regulation of heterosis at the physiological level. In this study, we performed a quantitative analysis of endogenous gibberellin (GA) content and expression profiling of the GA metabolism and signaling genes to investigate the possible relationship between GA signaling a...

Quantitative studies for investigating variation and its effect on heterosis of rice

An important step in plant breeding programs is identification of parents that are geneticallydistant from each other, to find crossing combinations with better prospects of hybrid vigor. Thepotential of identifying genetically distant parents depends on genetic diversity of population. 58 linesof rice from diverse origins have been employed to study genetic variation in order to identify themo...
