alkaligrass

alkaligrass provides a chromosome-level genome assembly and associated genomic analyses of Puccinellia tenuiflora to support study of halophyte saline and alkaline stress tolerance.

Key Features:

• High-Quality Genome Assembly: Chromosome-level assembly of approximately 1.50 Gb generated from Illumina short reads, PacBio long reads, 10× Genomics reads, and Hi-C data.
• Gene Encoding and Transposable Elements: The assembly encodes about 38,387 protein-coding genes and contains 54.9% transposable elements, predominantly long terminal repeats.
• Comparative Genomic Analysis: Comparative analyses with other Gramineae species identify unique genetic features and evolutionary traits.
• Stress-Responsive Gene Identification: Transcriptome profiling under saline and alkaline stress conditions identified unique stress-responsive genes.

Scientific Applications:

• Evolutionary Genomic Studies: Supports evolutionary analyses within the Gramineae family to investigate genetic adaptations of monocotyledonous halophytes.
• Stress Tolerance Research: Enables identification and study of saline- and alkaline-responsive genes to elucidate molecular mechanisms of stress tolerance.
• Agricultural Biotechnology: Provides genomic targets to inform development of genetically modified or bred crops with enhanced resistance to salinity and alkalinity.

Methodology:

Assembly integrated Illumina short reads (high-accuracy), PacBio long reads (long-read resolution), 10× Genomics reads (scaffolding), and Hi-C chromatin conformation data to generate a contiguous chromosome-level assembly.
