“…In the year 2000, India becomes a part of IRGSP and took the challenge of sequencing chromosome 11 jointly ventured by University of Delhi South Campus (UDSC), the National Research Centre on Plant Biotechnology (NRCPB) and the Indian Agricultural Research Institute (IARI), New Delhi. Recently, Indian scientists have developed markers and detected fragrance alleles in the rice varieties [61–62].…”

Biodiversity is a fundamental property of all natural systems existing in the field biology. It refers to the underlying heterogeneity at different levels of ecology, genetics and evolution. In case of plant systems, dramatic variability has been observed during the Anthropocene at different spatial scales. Environmental stress is one of the major influencing factors behind this plant biodiversity. Huge genetic diversity has been also demonstrated across varieties of important crop species like rice. Repetitive sequences which are a major contributor of genomic diversity in polyploidy plants have been found to occur ubiquitously in their genomes. To date diverse repeat types have been characterized in the plant genomes performing various functions starting from qualitative trait markers to genome evolution and stress management. With an objective to identify of plant stress associated genes using DNA repeat probes, a robust method has been developed. The method has been modularized into three distinct sections. First part is dedicated for identification of different types of repeats. Earlier review has suggested building a pipeline of multiples tools for capturing different types of repeats from the genome sequences. Specialized tools like TROLL, Tandem repeat finder (TRF), PHOBOS and database like REPBASE have been selected for performing this job. Second module is intended for screening of stress related genes from the published articles and databases and the last module has been designed for the association mining between genomic repetitive patterns with stress phenotypes. The method has been used to explore stress associated repeats from 9 Oryza species from different continents and other plants like Arabidopsis and Brachypodium. In case of Oryza species distribution repeats has been found to be significantly different between stress associated and housekeeping genes. More than 55% of the repeats are found to be in positive association (nPMI > 0) whereas 26% of the repeats are false-positives. These repetitive probes have been utilized in several applications. Firstly, using as molecular markers to identify stress related genes in different Oryza species where availability is limited. Secondly, using as a probe to reanalyzing the evolutionary lineage of Oryza species etc.

“…Selection for aroma using conventional breeding methods is very burdensome as it is expressed by quantitative traits. The strong influence of the environment on the development of fragrance is one of the major reasons along with low selection efficiency and narrow-sense heritability (Hu et al, 2020;Vemireddy et al, 2021). Sensory evaluation, near-infrared spectroscopy, and gas chromatography are a few methods that are employed to evaluate fragrant lines (Hu et al, 2020).…”

The current unpredictability of the climate is, directly and indirectly, affecting global food and nutritional security. In this instance, nutritional enrichment major attribute that is eventually necessary to help conventional crops become more resilient to future calamities. Sorghum is a crop widely acknowledged to be sustainable for the future due to its ability to withstand environmental variations and its crucial role in guaranteeing food and nutritional security. However, the primary obstacle to its broad appeal is the difficulty of garnering public approval. Perhaps the possible solution might lie in the scented sorghum which has enhanced flavors and distinct sensory qualities. The global population has responded most affectionately to fragrant cereals, and apparently, the same opportunity can be utilized by scented sorghum cultivars. It unveils an expanded potential for offering enhanced nutrients per portion compared to conventional alternatives, and it is quite probable that customers would choose them as a fragrant substitute based on previously observed choices. This paper briefly discusses the historical background and current advancements in scented sorghum research. Additionally, it examines the genetic makeup and molecular approaches applied to the diverse fragrant crops, potentially paving the way for sorghum to become a future defender of food and nutritional security. It further emphasizes that combining a nutrient-rich cereal like sorghum with enhanced fragrance and flavors has the potential to enhance its appeal and make it more accessible on the consumer's plate.
