The genetic architecture of leaf vein density and its importance for photosynthesis in maize
New Phytologist, EarlyView.Vein types in maize leaves. Summary Leaf venation density has significantly increased during plant evolution. Higher densities are observed in angiosperms compared with early land plants, and among angiosperms, recently diverged C4 species have the highest values.

Structural Variations Contribute to Subspeciation and Yield Heterosis in Rice
Plant Biotechnology Journal, EarlyView.ABSTRACT Yield heterosis has been extensively exploited in hybrid breeding, with intersubspecific hybrids often exhibiting the most pronounced effects. However, developing elite hybrids remains a laborious and time‐consuming process. The genetic basis of heterosis has been debated for over a century, hindered largely by the lack of high‐quality genomes.

BioEssays, Volume 48, Issue 6, June 2026.Zebrafish illustrates how polygenic sex determination, maternal germline bottlenecks, and a structurally restless genome jointly destabilize deep homozygosity. These interlocking constraints make fully isogenic zebrafish lines effectively unattainable, turning this model into a natural “stress test” for assumptions about genetic background and ...

New Phytologist, Volume 250, Issue 5, Page 2966-2987, June 2026.Summary The oleoresin defense system of loblolly pine (Pinus taeda) protects trees from insects and pathogens and is an important source of renewable biofuels and chemicals, but the genetic basis of oleoresin production is poorly understood. We characterized the genetic architecture of oleoresin flow, resin canal number, stem wood terpene content, and ...

USING GENERAL AND SPECIFIC COMBINING ABILITIES TO EXPECTED BREEDING VALUES, GENETIC VALUES AND HYBRID PERFORMANCE IN CHICKENS [PDF]
Egyptian Poultry Science, 2017 The objectives of this study were to investigate the difference in body weight due to crossing of one exotic meat type strain [Sasso chickens (SS)] and one developed local chicken strain [Gimmizah (GG)] in a full 2×2 diallel design to estimate ...

Convergence and parallelism in the evolution of plant metabolism
Journal of Integrative Plant Biology, Volume 68, Issue 4, Page 1013-1031, April 2026.Similar traits in different organisms may originate from shared ancestry or evolve independently. The terminology used to define phenotypic similarity is often confusing. This review attempts to clarify the definitions and present examples from plant domestication and specialized metabolism to explain how complex traits evolve repeatedly in plants ...
