| Abstract | Male sterility, especially cytoplasmic male sterility (CMS) where no functional pollen is produced, plays an important role in wheat breeding. Some specific proteins are related to male sterility in wheat, especially those present in pollen. To elucidate these sterility-related proteins, we applied two-dimensional gel electrophoresis (2-DE) to the proteomic analysis of pollen from a CMS line (732A) and its maintainer (732B) in wheat (Triticum aestivum L.), where trichloroacetic acid/acetone precipitation was used to extract pollen proteins from the wheat anthers. Analysis using PDQuest detected >350 reproducible protein spots on each 2-DE gel, where pI 4–7. In total, 41 spots were found to be differentially expressed, where 7/41 were identified by MALDI TOF/TOF–mass spectrometry analysis and protein database searching. The proteins comprised NADPH-producing dehydrogenase in the oxidative pentose phosphate pathway, cinnamyl alcohol dehydrogenase, cytosolic 3-phosphoglycerate kinase, caffeic acid O-methyltransferase, ascorbate peroxidase, glutamine synthetase isoform GS1a, and one unknown protein. In the uninucleate stage, all of the identified protein spots were downregulated in 732A, except the unknown protein, whereas there were no obvious differences in 732B. In the binucleate stage, the expression level of glutamine synthetase isoform GS1a did not differ between 732A and 732B, but caffeic acid O-methyltransferase was downregulated in 732A and the other five proteins were upregulated in 732A. These results suggest that male sterility in 732A is related to energy metabolism perturbation, active oxygen accumulation, programmed cell death, the pentose phosphate pathway, and glycolysis. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
