TLDR
The fertility restore gene for BT type cytoplasmic male sterility (BT-CMS) was detected and weedy rice was very valuable germplasm resources with the abundant polymorphism and should be modified by hybridization, backcross and multiple cross with japonica rice.About:

TL;DR: This review outlines some of the latest biotechnological tools to dissect the genetic backgrounds of several favorable traits of weedy rice that may prove beneficial for breeding and evolutionary studies on cultivated rice.
Journal ArticleDOI
Introgression and selection shaping the genome and adaptive loci of weedy rice in northern China.
TL;DR: It is found that extensive introgression from local cultivars, combined with the continuing ability to maintain weedy genes, is characteristic of weedy rice in northern China, providing a clue for the field control ofweedy rice.

Effects of Exogenous Abscisic Acid on Antioxidant System in Weedy and Cultivated Rice with Different Chilling Sensitivity under Chilling Stress
TL;DR: The results indicate the mechanism for rice with chilling tolerance is to enhance the capacity of antioxidant defence systems under chilling stress.

Disna Ratnasekera,Udugahapattuwage I.P. Perera,Zhuoxian He,Senanayakage G.J.N. Senanayake,Gamage A.W. Wijesekara,Xiao Yang,Bao-Rong Lu +6 more
TL;DR: Knowledge of such a morphological variation pattern provides opportunities to design strategic management methods for weedy rice control in Sri Lanka, in addition to the proper use of it as a genetic resource for rice improvement.

Comparison of Agronomic Performance between Japonica/Indica Hybrid and Japonica Cultivars of Rice Based on Different Nitrogen Rates
Tao Sun,Xin Yang,Xiaoli Tan,Kefeng Han,Sheng Tang,Weiming Tong,Siyi Zhu,Zhaoping Hu,Lianghuan Wu +8 more
TL;DR: The results showed that grain yields of all the varieties increased with increasing nitrogen application rates, except for Jia 58 whose optimum nitrogen level was 225 kg ha−1, because no significant difference was observed between N225 and N300.

Sampling variances of heterozygosity and genetic distance
Masatoshi Nei,A. K. Roychoudhury +1 more
TL;DR: The utility of the inter-locus variance of heterozygosity for studying the mechanism of maintenance of genetic variability in populations is indicated and mathematical formulae for the sampling variances are developed.

Cytoplasmic Male Sterility of Rice with Boro II Cytoplasm Is Caused by a Cytotoxic Peptide and Is Restored by Two Related PPR Motif Genes via Distinct Modes of mRNA Silencing

TL;DR: It is shown in rice (Oryza sativa) with Boro II cytoplasm that an abnormal mitochondrial open reading frame, orf79, is cotranscribed with a duplicated atp6 (B-atp6) gene and encodes a cytotoxic peptide and plays an additional role in promoting the editing of atp 6 mRNAs, independent of its cleavage function.

Positional cloning of the rice Rf-1 gene, a restorer of BT-type cytoplasmic male sterility that encodes a mitochondria-targeting PPR protein.

TL;DR: A rice Rf-1 gene is found that restores BT-type CMS by applying a positional cloning strategy and nine duplications of R f-1A homologs were found around the RF-1 locus in the Nipponbare genome but they do not restore BT- type CMS based on the lack of co-segregation with the restoration phenotype.
Journal ArticleDOI
Genetic diversity and its relationship to hybrid performance and heterosis in rice as revealed by PCR-based markers.
TL;DR: Results indicated that genetic distance measures based on RAPDs and SSRs may be useful for predicting yield potential and heterosis of intra-subspecific hybrids, but not inter-subspecies hybrids.
