A study by the University of Tsukuba found that changes in F1-hybrid metabolites lead to increased biomass in Arabidopsis plants. The researchers analyzed 202 Arabidopsis lines and found altered production of intermediate metabolites of the TCA cycle in high-heterosis combinations.
Research at North Carolina State University reveals that soil microbes significantly impact heterosis, or hybrid vigor, in corn plants. In experiments with sterile bags and field tests, hybrid lines outperformed inbred lines due to microbial effects on root growth and biomass.
A team of researchers at the University of Kansas discovered that soil microbes facilitate heterosis, also known as hybrid vigor, in hybrid corn. In most cases, heterosis is restored by inoculation with a simple community of seven bacterial strains under sterile conditions.
Subgenome fractionation determines hybrid vigor in maize, with one subgenome experiencing more gene loss than the other. This leads to increased protein accumulation and a nonadditive effect on heterosis in F1 plants.
Researchers from Utah State University, Thomas Hill and Andreas Malmendier, explore the duality between F-theory and heterotic string theory in eight dimensions. They discovered four unique ways to slice K3 surfaces as Jacobian elliptic fibrations, enabling investigation of underlying physical theories.
Researchers have decoded the European maize genome, revealing significant differences in genetic content and genome structure compared to North American lines. These findings suggest that heterosis, a phenomenon increasing crop yields, may be influenced by variations in knob regions and gene regulation.
Researchers found that hybrids become more productive as genetic distance between parents increases, contradicting previous contradictory studies. The team's study provides clarity to the issue, enabling rational selection of crossing partners for breeding new hybrid varieties.
Researchers at Kansas State University have identified a key genetic link that enhances heterosis in sorghum, leading to improved plant height and potential increases in crop yield. The findings offer new insights into the complex genetic phenomena of heterosis and its impact on economically important traits.
Researchers at the University of Bonn have decoded a possible mechanism for hybrid corn's high yield, finding that more genes are active in hybrid plants than in their homozygous parental lines. This increase in gene activity could lead to increased growth and vigor in hybrids.
Researchers at the University of Hohenheim have developed a new technique to select promising parent plants for corn breeding, allowing for faster development of high-yielding varieties. By analyzing DNA and substance composition, scientists can predict a plant's genetic potency and breeding capabilities, saving time, money, and acreage.
A random sample of 1205 black, white, and mixed-race faces showed mixed-race individuals were rated as more attractive. The study's findings suggest a biological phenomenon known as heterosis may contribute to this perception.
Researchers at Hebrew University and CSHL found a single gene that boosts yield and improves taste in hybrid tomato plants, working across various environmental conditions. The discovery has potential to transform the billion-dollar tomato industry and agricultural practices.
Researchers have discovered a single gene responsible for increased yield and improved sweetness in hybrid tomato plants. The gene, called florigen, produces a protein that regulates flowering and fruit production, leading to higher yields and sweeter fruits.
Researchers identified 'dominance complementation' as a key factor in hybrid vigor, revealing that hybrids benefit from genes and regulatory factors beyond simple parent combinations. This discovery could lead to stronger, healthier, or more productive corn strains.
Researchers found that closely related genes in maize can be located elsewhere in the genome, leading to increased hybrid vigor. This discovery has important implications for improving agriculture and developing new, more productive lines of corn.
