Summary
We developed the Poaceae Intronless Genes Database (PIGD) to consolidate information on intronless genes in plants. This resource aids research into gene evolution and comparative genomics.
Area of Science:
- Genomics
- Bioinformatics
- Evolutionary Biology
Background:
- Intronless genes, common in prokaryotes, are also found in eukaryotes and offer insights into gene architecture evolution.
- Existing databases lack a centralized resource for plant intronless genes.
Purpose of the Study:
- To create a comprehensive database for intronless genes in plants.
- To provide a user-friendly platform for accessing and analyzing intronless gene data.
Main Methods:
- Developed the Poaceae Intronless Genes Database (PIGD) with a web interface.
- Integrated gene annotation and sequence data for five Poaceae species.
- Included gene descriptions, product records, functional annotations, and localization predictions.
Main Results:
- PIGD offers data on intronless genes from Sorghum bicolor, Zea mays, Setaria italica, Panicum virgatum, and Brachypodium distachyon.
- The database provides tools for browsing, searching, downloading data, and performing BLAST and comparative analyses.
- Functional annotations and taxonomic distribution of intronless genes are reported.
Conclusions:
- PIGD serves as a valuable platform for collecting, integrating, and analyzing intronless genes in the Poaceae family.
- The database supports bio-computational analysis in comparative genomics and evolutionary studies.

Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.

Recombinant DNA technology called transgenesis is often used to add a foreign gene or remove a detrimental gene from an organism. Such genetically modified organisms are called transgenic organisms.
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...

The diverse plant life on Earth—consisting of nearly 400,000 species—can be divided into three broad categories based on biological characteristics: nonvascular, seedless vascular, and seed plants.

02:16Light Acquisition
8.0K
In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.
