| Abstract | Background Chenopodium quinoa Willd (Quinoa) is highly tolerant to drought, cold, and salt stress. Gene editing technology development, and research on quinoa’s drought resistance have attracted much attention. The transcriptional cofactor VQ plays an important role in the drought response in plants, but its role in quinoa has not been reported. Results Bioinformatics identified 23 members of the quinoa VQ gene family, mainly located in the nucleus and unevenly distributed on 10 chromosomes. Gene structure and phylogenetic analysis indicated that the VQ genes were closely related and highly conserved, forming three subfamilies. The cis-acting elements of the promoter reveal its involvement in the response to light and hormonal stress. qRT-PCR analysis showed that all VQ genes were differentially expressed under drought stress, among which CqVQ13 was significantly up-regulated, and subcellular localization indicated that it was localized to the nucleus. Conclusion This study conducted a systematic bioinformatics analysis of the basic physicochemical properties and chromosome localization of 23 members of the CqVQ gene family. Combined with transcriptome gene expression profiling and qRT-PCR, we found that CqVQ13 was significantly up-regulated under drought stress and localized in the nucleus. This discovery provides an important candidate gene for drought response studies in quinoa and lays the foundation for further exploration of the molecular mechanisms of the VQ gene family in response to drought stress. |

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.
