The genetic architecture of leaf vein density and its importance for photosynthesis in maize

open access: yesNew Phytologist, Volume 251, Issue 4, Page 1738-1754, August 2026.
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.

Diallel Analysis of Early Leaf Spot (Cercospora arachidicola Hori) Disease Resistance in Groundnut

open access: yesAgronomy, 2019
Early leaf spot (ELS) is one of the major biotic constraints of groundnut production in West and Central Africa. A study using 6 × 6 F2 full diallel populations from six parents (NAMA, B188, PC79-79, QH243C, TS32-1, and CN94C) was conducted to ...

Performance of testers with different genetic structure for evaluation of maize inbred lines Desempenho de testadores com diferentes estruturas genéticas para avaliação de linhagens endogâmicas de milho

open access: yesCiência Rural, 2012
The objective of this study was to evaluate four maize testers for identification of superior inbreed lines in testcross. The four testers evaluated are cultivars with narrow or wide genetic base (single-cross hybrids and open pollinated varieties) and ...

Zebrafish as an Anti‐Isogenic Vertebrate Model and What It Reveals About Genetic Background and Reproducibility

open access: yesBioEssays, 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 ...

Constitutive and inducible oleoresin defenses share genetic architectures and mechanisms in Pinus taeda

open access: yesNew 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 ...

Study on gene action of yield and its attributes in rice (Oryza sativa L.) under phosphorus-deficient conditions using Griffing’s approach

open access: yesElectronic Journal of Plant Breeding
Phosphorus (P) deficiency drastically limits rice production in tropical soils, necessitating the development of P-efficient varieties. The present study evaluated the combining ability of eight rice parents and their 28 F1 hybrids, which were produced ...

Human Diallelic Insertion/Deletion Polymorphisms [PDF]

open access: yesThe American Journal of Human Genetics, 2002
We report the identification and characterization of 2,000 human diallelic insertion/deletion polymorphisms (indels) distributed throughout the human genome. Candidate indels were identified by comparison of overlapping genomic or cDNA sequences.

Convergence and parallelism in the evolution of plant metabolism

open access: yesJournal 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 ...
