A robust biotechnology induces artificial genomic duplication via transient RNAi‐mediated suppression of OSD1 in rice

Journal of Integrative Plant Biology, EarlyView.
Plant Polyploidization via Gene Interference, a robust technology for inducing polyploidy in various rice accessions, uses transient RNAi‐mediated suppression of OSD1 to induce genomic duplication. Two strategies were used to directly induce fertile autotetraploid plants in the first generation, thereby substantially shortening the breeding cycle ...

Whole‐genome duplication promotes phenotypic and genetic adaptation to elevation

New Phytologist, EarlyView.
Fitness of diploids (2x) and tetraploids (4x) of Biscutella laevigata from low (circles) and high (triangles) elevation transplanted across elevation at 585, 1236 and 1967 m above sea level. Summary Whole‐genome duplication (WGD) is often considered as either an adaptive dead‐end or a facilitator of rapid adaptation under changing environments.

Foliar Pectins and Physiology of Diploid and Autotetraploid Mango Genotypes under Water Stress

Plants, 2023
The cultivation of mango in Mediterranean-type climates is challenged by the depletion of freshwater. Polyploids are alternative genotypes with potential greater water use efficiency, but field evaluations of the anatomy and physiology of conspecific ...

Excess endopolyploidy associated with cellular defects in neo‐autotetraploid Arabidopsis arenosa is in part corrected by a naturally evolved allele of CYCD3;2

New Phytologist, EarlyView.
Ploidy level distributions and endoreduplication profiles in diploid and tetraploid Arabidopsis arenosa. Summary Endopolyploidy (within‐organism polyploidy) is an often‐beneficial aspect of development. But polyploids, which have a higher baseline genome content, have been reported to have less endoreduplication than diploid relatives. Why has remained

New Considerations on Meiosis, Affinity and Genomic Constitution in Aneuploids and Interploid Hybrids of Urochloa P. Beauv. (Brachiaria)

Plant Breeding, EarlyView.
ABSTRACT The combination of polyploidy, apomixis and the formation of aneuploid and interploid hybrids makes the genus Urochloa an interesting system for investigating meiotic stability and genome behaviour in grasses. In this study, routine meiotic analysis and genomic in situ hybridization (GISH) were used to (i) evaluate meiosis in three hybrids of ...

Ploidy variation on gene differential expression in cowpea

Ciência Rural
: This study investigated the differences in gene expression profiles of diploid and autotetraploid in cowpea, and provided theoretical basis for screening key genes of differential expression and ploidy breeding.

Breaking Strength of Pedicel as an Index of Grain-Shattering Habit in Autotetraploid and Diploid Buckwheat (Fagopyrum esculentum Moench.) Cultivars

Plant Production Science, 1999
The grain-shattering habit was compared among diploid and autotetraploid cultivars of common buckwheat (Fagopyrum esculentum Moench.). In the first experiment, one diploid and one autotetraploid cultivar were grown in the field, and the number of grains ...

Improved Autotetraploid Induction Methods in Four Diploid Wild Peanut Species: Arachis duranensis, A. stenosperma, A. magna, and A. batizocoi

Plant Breeding, EarlyView.
ABSTRACT Peanut (Arachis hypogaea L., 2n = 4x = 40, AABB) is an important legume crop worldwide. Wild peanuts (Arachis spp.) represent a valuable secondary gene pool with diverse disease resistances. However, most wild peanut species are diploid (2n = 2x = 20) and this ploidy barrier is a major obstacle to hybridization and gene introgression.

Development and validation of a 40 K liquid SNP array in autotetraploid Pacific oyster (

Aquaculture Reports
Autotetraploid Crassostrea gigas is a significant economic species that plays a crucial role in the production of triploid C. gigas . Molecular markers are essential for oyster selective breeding, but the lack of an efficient high-throughput genotyping ...

Genomic and phenomic prediction models improve selection accuracy for complex traits in alfalfa

The Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Predictive breeding has been proposed as an effective approach to accelerate genetic gain for complex traits. Genomic prediction (GP) models have been developed in alfalfa (Medicago sativa L.) for key traits in the last decade. More recently, phenomic prediction (PP) models have been proposed as a low‐cost, high‐throughput alternative to GP in
