The RBMMDB (Ricebean Microsatellite Marker Database) serves as a powerful online platform designed to effortlessly retrieve crucial information regarding microsatellite markers in the realm of Ricebean research. RBMMDB contains searches for microsatellite markers in both genomic and transcriptomic data in ricebean, accessible through two different tabs: Genomic SSR and Genic SSR. For genomic data, a chromosome-wise search option is available, along with filters for SSR type, motif type, and repetition. For transcriptomic data, search options are provided based on SSR type, motif type, and repetition. Microsatellite marker's plot can also be viewed for both genomic and transcriptomic data using the SSR Plots tab. This database also includes Gene Ontology (GO) plots for both genomic and transcriptomic data through the GO Plots tab. By providing a straightforward interface, RBMMDB allows users to initiate searches with ease, utilizing tailored inputs to uncover specific microsatellite markers of interest.

Ricebean (Vigna umbellata)

• Ricebean is a type of legume crop, closely related to mung beans and black-eyed peas, belonging to the Vigna genus. They have a relatively short growth cycle, making them suitable for intercropping or as a rotation crop in farming systems.
• It has small, oblong-shaped seeds that come in different colors such as white, black, brown, and speckled varieties.
• Ricebean is known for their drought-tolerant nature, making them well-suited for cultivation in arid regions
• Like other legumes, ricebean has the ability to fix atmospheric nitrogen into the soil, enriching it naturally. The ability of ricebean to fix nitrogen in the soil reduces the need for synthetic fertilizers, promoting sustainable and eco-friendly agricultural practices
• Ricebean is highly nutritious, being a good source of protein, dietary fiber, vitamins (B-complex), and essential minerals like iron, potassium, and phosphorus It plays a vital role in contributing to food security, especially in regions facing challenging environmental conditions and limited food resources
• It has a relatively short growth cycle, making them suitable for intercropping or as a rotation crop in farming systems. Including ricebean in crop rotations helps diversify agriculture, reducing the risk of crop failure and improving soil fertility

Microsatellite markers

• Microsatellite markers are specific regions of DNA used to identify genetic variations and traits in organisms. They provide insights into genetic diversity, evolutionary relationships, and functional characteristics.
• SSR (Simple Sequence Repeat) or microsatellite, represents a repetitive DNA sequence composed of 1-6 base pairs that are tandemly repeated in a head-to-tail manner. These sequences are found throughout the genomes of various organisms, including plants, animals, and humans.
• The variability in the number of repeats within SSRs makes them valuable genetic markers for studying genetic diversity, population genetics, and plant breeding programs. The differences in the number of repeat units at a specific locus lead to the presence of multiple alleles, allowing researchers to analyze and understand genetic variation within populations.
• SSRs are widely used in microsatellite biology and genetics research due to their co-dominant inheritance pattern, abundance in genomes, and high degree of polymorphism.
