LMTdb: A comprehensive transcriptome database for climate-resilient, nutritionally rich little millet (Panicum sumatrense)

Abstract

Little millet (Panicum sumatrense) a native of Chhattisgarh, belongs to the minor millet group and is primarily known as a climate-resilient and nutritionally rich crop. However, due to the lack of enough Omic studies on the crop, the scientific community has largely remained unaware of the potential of this crop, resulting in less scope for its utilization in crop improvement programs. Looking at global warming, erratic climate change, nutritional security, and limited genetic information available, the Little Millet Transcriptome Database (LMTdb) (https://igkv.ac.in/xenom/index.aspx) was conceptualized upon completion of the transcriptome sequencing of little millet with the aim of deciphering the genetic signatures of this largely unknown crop. The database was developed with the view of providing information about the most comprehensive part of the genome, the ‘Transcriptome’. The database includes transcriptome sequence information, functional annotation, microsatellite markers, DEGs, and pathway information. The database is a freely available resource that provides breeders and scientists a portal to search, browse, and query data to facilitate functional and applied Omic studies in millet crops.

Mapping and Screening of Candidate Gene Regulating the Biomass Yield of Sorghum (Sorghum bicolor L.)

“…Protein BLAST analysis and Pfam analysis showed that Sobic.003G010300 encodes an SbCYP71A1 protein, which belongs to the Cytochrome P450 superfamily (CYP) (Figure 4A). Homology alignment and gene annotation revealed that the CYP71A1 gene codes for the tryptamine 5-hydroxylase enzyme (Figure 4B), a crucial component in the plant serotonin/melatonin biosynthesis pathway [30,31]. This confirmed that Sobic.003G010300 is a potential candidate gene for sblob1.…”

“… [ 3 ] For the climate-resistant, nutrient-dense little millet, a thorough transcriptome database was discovered. [ 52 ] Foxtail millets Genome sequencing was used to assess the resistance to biotic stress in foxtail millet. [ 53 ] RIL population and widely targeted metabolome were used to conduct QTL analysis of significant agronomic characteristics and metabolites in foxtail millet.…”
