Open AccessFull-length transcriptome reconstruction reveals genetic differences in hybrids of Oryza sativa and Oryza punctata with different ploidy and genome compositions
Allopolyploid breeding is an efficient technique for improving the low seed setting rate of autotetraploids in plant breeding and one of the most promising breeding methods. However, there have been few compre...

Open AccessUnique Glutelin Expression Patterns and Seed Endosperm Structure Facilitate Glutelin Accumulation in Polyploid Rice Seed
Rice is not only an essential food but also a source of high quality protein. Polyploidy is an evolutionary trajectory in plants, and enhancing glutelin by polyploidization is an attractive strategy for improv...

Open AccessCharge density waves and their transitions in anisotropic quantum Hall systems
In recent experiments, external anisotropy has been a useful tool to tune different phases and study their competitions. In this paper, we look at the quantum Hall charge density wave states in the N = 2 Landau l...

Open AccessOsMND1 regulates early meiosis and improves the seed set rate in polyploid rice
The meiotic processes of most polyploid rice (Oryza sativa) are genetically abnormal, leading to low pollen fertility, which results in low seed set rates. Some polyploid meiosis stability (PMeS) lines with high ...

Open AccessBreeding and study of two new photoperiod- and thermo-sensitive genic male sterile lines of polyploid rice (Oryza sativa L.)
Male sterile lines play an important role in the utilization of heterosis. To explore and exploit the heterosis of polyploid hybrid rice, two photoperiod- and thermo-sensitive genic male sterile lines of polyp...

Open AccessGenome duplication improves rice root resistance to salt stress
Salinity is a stressful environmental factor that limits the productivity of crop plants, and roots form the major interface between plants and various abiotic stresses. Rice is a salt-sensitive crop and its p...

Open AccessDevelopment and characterization of synthetic amphiploid (AABB) between Oryza sativa and Oryza punctata
Oryza punctata, a wild relative of cultivated rice, belongs to the BB genome of Oryza. Interspecific hybrids (CW008, AB) between Oryza sativa (2n = 24 AA) and O. punctata (2n = 24 BB) were obtain...

Genome duplication effects on pollen development and the interrelated physiological substances in tetraploid rice with polyploid meiosis stability
The breeding of polyploid rice made no breakthrough for a long time because of low seed set. The discovery and application of polyploid meiosis stability (PMeS) material played a pivotal role in solving this p...

The breeding of two polyploid rice lines with the characteristic of polyploid meiosis stability
Polyploidization is a basic feature of plant evolution. Nearly all of the main food, cotton and oil crops are polyploid. When ploidy levels increase, yields double; this phenomenon suggested a new strategy of ...

Regeneration of fertile plants from isolated tobacco zygotes byin vitro culture
Living zygotes of tobacco (Nicotiana Tabacum L.) SR-1 were isolated and culturedin vitro by the microculture technique. Fertile plants were regenerated from the calli derived from cultured zygotes via organogenes...
