| Abstract | GASR7 is a member of Snakin/GASA gene family in higher plants and has been found associated with grain length (GL) in rice and wheat under normal growth conditions. Here, we report the characterization of three distinct TaGASR7 homoeologs (TaGASR7-A1, TaGASR7-B1 and TaGASR7-D1) in common wheat and their deduced proteins and haplotype variation. TaGASR7 homoeologs were located on wheat group 7 chromosomes. Compared with previously characterized Snakin/GASA members, the central region in deduced TaGASR7 proteins and their orthologs was unique in containing a polyglycine tract. Through analyzing longer genomic sequence, more nucleotide differences were found for the two previously reported major haplotypes (H1c and H1g) of TaGASR7-A1. In contrast, no haplotype variation was detected for TaGASR7-B1 and TaGASR7-D1 in the 94 elite common wheat varieties examined. H1c, but not H1g, tended to associate with larger GL values in nine cultivation environments differing in water and nutrient application. However, the positive association between H1c and other grain traits (grain weight and yield) was affected by cultivation environment. Both H1c- and H1g-type alleles were more highly expressed in the unfertilized caryopses and those collected at 5 days after flowering (DAF). Interestingly, at 5 DAF, the expression level of H1c-type alleles was significantly lower than that of H1g-type alleles. By combining our data with those published previously, we suggest that TaGASR7-A1 is mainly a genetic determinant of GL in wheat with pleiotropic effects on grain weight and yield. Potential mechanism underlying TaGASR7-A1 function and its utility in enhancing genetic and breeding studies of wheat grain morphometric and yield traits are discussed. |

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.
