“…From the analysis of different sets of F 2 samples in 2 years, we identified the same major gene locus taf1 on chromosome 2DS associated with female fertility. This locus was different from any other locus associated with male fertility found in wheat so far (Ma, 1995 ;Fu, 2002 ;Liu, 2002;Xing, 2003;Zhang, 2003;Cao, 2004 ;Li, 2005 ;Guo, 2006). Based on our results, female fertility might be an independent genetic system different from that of male fertility.…”

Studies on inheritance of fertility are of great importance in wheat breeding. Although substantial progress has been achieved in molecular characterization of male sterility and fertility restoration recently, little effort has been devoted to female sterility. To identify the gene(s) controlling female sterility in wheat efficiently, an investigation was conducted for the seed setting ratio using a set of F2 populations derived from the cross between a female sterile line XND126 and an elite cultivar Gaocheng 8901. Bulked segregation analysis (BSA) method and recessive class approach were adopted to screen for SSR markers potentially linked to female fertility gene loci in 2005. Out of 1080 SSRs in wheat genome, eight markers on chromosome 2D showed a clear difference between two disparate bulks and small recombination frequency values, suggesting a strong linkage signal to the sterility gene. Based on the candidate linked markers, partial linkage maps were constructed with Mapmaker 3.0 (EXP) instead of whole genome maps, and quantitative trait locus (QTL) mapping was implemented with software QTLNetwork 2.0. A major gene locus designated as taf1, was located on chromosome 2DS. The above result was confirmed by the analysis for 2007 data, and taf1 was identified on the same chromosome 2DS with a confidence interval of 2.4 cM, which could explain 44.99% of phenotypic variation. These results provided fundamental information for fine mapping studies and laid the groundwork for wheat fertility genetic studies.

Aliphatic Metabolism during Anther Development Interfered by Chemical Hybridizing Agent in Wheat

Chemically‐interfered male sterility (CIMS) system in wheat (Triticum aestivum L.) is one of the male sterility types used for hybrid wheat production in China. The main morphological defect in male sterile line 1376‐CIMS interfered by chemical hybridizing agents (CHA) is that the tapetum seems to be abnormally degrated and pollen extine is aberrant. As a complex pollen wall in wheat, the pollen outer wall mainly contains lipidic sporopollenin. However, the mechanism for synthesizing these aliphatic precursors during pollen development has not been fully elucidated. To elucidate the relationship between aliphatic mechanism and chemically‐interfered male sterility, we report on the function of SQ‐1 (a new kind of chemical hybridizing agent) in aliphatic metabolism and its disruptive role during wheat pollen development. The observations of scanning electron microscopy revealed that anther and pollen wall formation was significantly altered in 1376‐CIMS. The contents of aliphatic compositions of anther underwent changes in 1376‐CIMS revealed by gas chromatography–mass spectrometry (GC–MS), including in particular reductions in fatty alcohols, alkanes and alkenes, and an abnormal increase in fatty acids in 1376‐CIMS. cDNA‐AFLP data revealed that an array of genes implicated in a diversity of biological pathways (180 in total, 124 up‐expression and 56 down‐expression) exhibited statistically significant expressional differences between 1376 and 1376‐CIMS. Also, a group of genes putatively involved in aliphatic transport and metabolism were significantly altered in 1376‐CIMS, indicating the disruptive role of SQ‐1 in aliphatic transport and metabolism in the formation of the anther and pollen wall. In addition to its function in promoting tapetum programmed cell death (PCD), SQ‐1 probably plays crucially perturbative roles in several basic biological processes during wheat anther development.

“…The mapping analysis indicated that the male sterile gene wptms3 located on chromosome 1B, flanked by Xgwm413 and Xgwm182, differed from those reported by Guo et al (2006b) and thus is a new gene. To date, several fertility restoring genes against CMS in wheat have been mapped on chromosome 1B (Ahmed et al, 2001;Li et al, 2005;Zhou et al, 2005). Therefore, there are regions on chromosome 1B related to fertility performance.…”

Utilization of a two-line breeding system via photoperiod-thermo sensitive male sterility has a great potential for hybrid production in wheat (Triticum aestivum L.). 337S is a novel wheat male sterile line sensitive to both short daylength/low temperature and long daylength/high temperature. Five F(2) populations derived from the crosses between 337S and five common wheat varieties were developed for genetic analysis. All F(1)'s were highly fertile while segregation occurred in the F(2) populations with a ratio of 3 fertile:1 sterile under short daylength/low temperature. It is shown that male sterility in 337S was controlled by a single recessive gene, temporarily designated as wptms3. Bulked segregant analysis (BSA) coupled with simple sequence repeat (SSR) markers was applied to map the sterile gene using one mapping population. The wptms3 gene was mapped to chromosome arm 1BS and flanked by Xgwm413 and Xgwm182 at a genetic distance of 3.2 and 23.5 cM, respectively. The accuracy and efficiency of marker-assisted selection were evaluated and proved essential for identifying homozygous recessive male sterile genotypes of the wptms3 gene in F(2) generation.
