Polyploid rice: new resources for future rice breeding

, 2023
Asian cultivated rice (Oryza sativa L.) is a diploid species with two sets of 12 chromosomes (2n= 24). Despite the fact that Asian cultivated rice may have experienced whole genome duplication more than 96 million years ago, this species is regarded as ...

Recent advances in the genomics of sugarcane (Saccharum)

Journal of Integrative Plant Biology, EarlyView.
This review systematically summarizes advances in sugarcane genomics, evolution, classification, and breeding practices. It identifies key research bottlenecks and proposes an integrated research framework to facilitate predictive sugarcane breeding, which provides valuable references for genetic improvement of other complex polyploid crops.

The Analysis of Polyploid Genetic Data [PDF]

, 2018
Though polyploidy is an important aspect of the evolutionary genetics of both plants and animals, the development of population genetic theory of polyploids has seriously lagged behind that of diploids. This is unfortunate since the analysis of polyploid

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 ...

Analysis of the formation mechanisms and biological characteristics in WuLi carp-like fish derived from the hybrid of Cyprinus carpio var. Quanzhounensis (♀) × Carassius auratus red var. (♂)

Aquaculture Reports
Distant hybridization is an effective strategy for creating polyploids and developing new germplasm resources in fish genetic breeding. The WuLi carp-like fish (2 n = 100, WCL) had been obtained through distant hybridization between female WuLi carp ...

TaANT11‐4A enhances grain yield by orchestrating photosynthesis and carbohydrate metabolism through direct transcriptional activation

Journal of Integrative Plant Biology, EarlyView.
TaANT11‐4A is a positive regulator of wheat grain size and yield, directly activating TaEGY2, TaAAE1, and TaAAE2 to enhance photosynthesis and carbohydrate metabolism. The favorable Hap2 haplotype increases TaANT11‐4A expression and grain size, providing a genetic resource for breeding higher‐yielding wheat varieties.

Comparative analysis of intermuscular bones in hybrid of female (megalobrama amblycephala × culter alburnus) × male megalobrama amblycephala and its parents

Reproduction and Breeding
Based on the formation of the hybrid lineage of blunt-snout bream (megalobrama amblycephala, BSB) × topmouth culter (culter alburnus, TC), a new kind of hybrid fish is produced by hybridizing the female diploid F1 hybrid of BSB × TC (short for BT) with ...

Chromosome Pairing in Polyploid Grasses

, 2020
International audiencePolyploids are species in which three or more sets of chromosomes coexist. Polyploidy frequently occurs in plants and plays a major role in their evolution.
