BPDRTDb

BPDRTDb catalogs transcriptome-derived genomic resources from drought-affected black pepper (Piper nigrum L.) roots and leaves to support research and breeding for drought tolerance.

Key Features:

• Differentially Expressed Genes: Contains data on 4,914 genes differentially expressed in response to drought stress.
• Transcription Factors: Includes information on 2,110 transcription factors identified from the transcriptome analysis.
• Protein Domains and Families: Catalogs 786 domains and 1,137 protein families involved in drought responses.
• Molecular Markers: Features 20,124 putative Simple Sequence Repeat (SSR) markers and 259,236 variants, including Single Nucleotide Polymorphisms (SNPs) and Insertions/Deletions (InDels).
• Pathways: Provides insights into pathways implicated in drought tolerance for systems-level analyses.
• Sequencing and Assembly Data: Data were generated using Illumina HiSeq2000 and include de novo assemblies produced with the Trinity assembler.

Scientific Applications:

• Genetic Improvement and Breeding: Supports breeding programs aimed at developing drought-tolerant black pepper varieties using genomic data and molecular markers.
• Marker Development and Association Studies: Supplies SSRs, SNPs, and InDels for marker-assisted selection and genetic mapping.
• Gene Discovery and Functional Genomics: Enables identification of candidate genes and transcription factors involved in drought response.
• Pathway and Systems Biology Analyses: Facilitates pathway-level investigation of molecular mechanisms underlying drought tolerance.

Methodology:

Data were generated using Illumina HiSeq2000 sequencing of drought-affected black pepper leaves and de novo assembled with the Trinity assembler.
