Diurnal plant tools

Diurnal plant tools analyzes diurnal gene co-expression and co-function networks across photosynthetic organisms within Archaeplastida, including the broadly defined Plantae, to study temporal regulation of gene expression.

Key Features:

• Extensive Database: Integrates gene expression data from 17 diurnal studies covering a wide array of species across Archaeplastida, including Plantae.
• Co-expression and Co-function Network Analysis: Constructs and analyzes co-expression and co-function networks to identify functionally related gene modules and co-expressed clusters.
• Time-Specific Analysis: Performs time-resolved analyses to pinpoint genes and modules expressed at specific times of the diurnal cycle.
• Cross-Species Comparative Analysis: Compares whole co-expression networks and co-expressed clusters across species to assess evolutionary conservation.

Scientific Applications:

• Evolution of Cell Division: Analyzes diurnally regulated gene modules to study how cell division processes have evolved across different plant lineages.
• Diurnal Control in Algae: Investigates temporal regulation of gene expression in algae to reveal diurnal physiological and metabolic adaptations.
• Conservation Across Species: Identifies conserved diurnally controlled modules across species to infer evolutionary pressures and functional conservation.

Methodology:

Integrates and analyzes large-scale gene expression datasets from multiple studies, constructs co-expression networks, and identifies functionally related gene modules expressed at specific times of the day, relating transcriptional patterns to environmental cues such as light.
