Data from: Morphological, cellular and molecular evidences of chromosome random elimination in vivo upon haploid induction in maize

Fazhan Qiu, Yanli Liang, Yan Li, Yongzhong Liu, Liming Wang & Yonglian Zheng
The mechanism of maternal in vivo haploid induction is not fully understood. In this study, the young embryos were identified by morphology, cytology and simple sequence repeat (SSR) markers at different developmental stages in the cross HZ514 (sweet corn) × HZI1 (inducer). The results indicated that the low seed setting rate was determined by the inducer pollen during the process of fertilization. The mosaic endosperm kernels and the different percentages of aneuploidy, mixploidy, lagged chromosome,...

Data from: Analysis of hypoxia-inducible factor alpha polyploidization reveals adaptation to Tibetan plateau in the evolution of schizothoracine fish

Lihong Guan, Wei Chi, Wuhan Xiao, Liangbiao Chen & Shunping He
Background: Hypoxia-inducible factor (HIF) is a master regulator that mediates major changes in gene expression under hypoxic conditions. Though HIF family has been identified in many organisms, little is known about this family in schizothoracine fish. Results: Duplicated hif-α (hif-1αA, hif-1αB, hif-2αA, and hif-2αB) genes were identified in schizothoracine fish. All the deduced HIF-α proteins contain the main domains (bHLH-PAS, ODDD, and TAD), also found in humans. Evidence suggests a Cyprinidae-specific deletion, specifically, a conserved...

Data from: Inferring outcrossing in the homothallic fungus Sclerotinia sclerotiorum using linkage disequilibrium decay

Weidong Chen, Renuka N. Attanayake, Vidhura Tennekoon, Dennis A. Johnson, Lyndon D. Porter, Luis Del Río-Mendoza & Daohong Jiang
The occurrence and frequency of outcrossing in homothallic fungal species in nature is an unresolved question. Here we report detection of frequent outcrossing in the homothallic fungus Sclerotinia sclerotiorum. In using multilocus linkage disequilibrium (LD) to infer recombination among microsatellite alleles, high mutation rates confound the estimates of recombination. To distinguish high mutation rates from recombination to infer outcrossing, 8 population samples comprising 268 S. sclerotiorum isolates from widely distributed agricultural fields were genotyped for...

Data from: Genome-wide analysis reveals artificial selection on coat colour and reproductive traits in Chinese domestic pigs

Chao Wang, Hongyang Wang, Yu Zhang, Zhonglin Tang, Kui Li & Bang Liu
Pigs from Asia and Europe were independently domesticated from c. 9000 years ago. During this period, strong artificial selection has led to dramatic phenotypic changes in domestic pigs. However, the genetic basis underlying these morphological and behavioural adaptations is relatively unknown, particularly for indigenous Chinese pigs. Here, we performed a genome-wide analysis to screen 196 regions with selective sweep signals in Tongcheng pigs, which are a typical indigenous Chinese breed. Genes located in these regions...
