      Climate change, along with current agricultural practices, is going to pose a significant challenge for futurefood security, especially in developing countries. Orphan crops can help mitigate this threat due to theirinherent properties of stress tolerance and nutrition content. Industrialization of agriculture has left these minorcrops behind in terms of domestication. As a result, the potential of these crops is underutilized. These cropscan be a game-changer in the long term if necessary steps are taken to improve the quality as well as quantity ofyield. Concerted efforts by many groups around the world have been taken for research and development ofthese crops. Besides, the unique properties of these crops have caught the media attention, which hails thesecrops as superfoods. Favourable government policies to promote these crops can help in the large-scaleadoption of these crops by the farming community. Besides, the stress-resilience of these crops can help boostthe sustainability of agriculture and ensure food security for future generations.

      GRAS proteins are multi-functional, regulating various aspects of plant growth and development. Besides,they are also involved in the stress tolerance of plants. Wheat is one of the major cereal crops of theworld and efforts are being made to boost its productivity and stress tolerance to feed the increasing worldpopulation. Being a physiologically important transcription factor, GRAS genes can open up new avenuesfor improvement in wheat. The recent availability of the hexaploid genome sequence of bread wheat(Triticum aestivum) provides us an excellent opportunity to analyse the GRAS gene family and gainfunctional insights. In this study, we identified 183 GRAS genes coding for 194 GRAS proteins.Chromosomal location was identified for all the genes to give some idea about gene duplications.Sequence alignment, followed by phylogenetic analysis helped to classify the TaGRAS genes in 12 subfamilies.Gene and protein structure analysis revealed conservation among the different sub-families.Transcriptome analysis was done using available databases, to reveal the expression pattern underdevelopmental conditions as well as different stress conditions. Altogether, these datasets give importantinsights into the functional role of different GRAS family members of bread wheat. Besides, it provides animportant resource for future investigations into the physiological role of GRAS genes in bread wheat.Finally, this study identified potentially important TaGRAS genes which may help to boost yields andstress tolerance of wheat via control of various physiological aspects.
