Plant Breeding and Biotechnology

21.9K
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.

Gene Families

10.1K
Gene families consist of groups of genes proposed to have originated from a common ancestor. Typically these arise through events in which a gene or genes are mistakenly duplicated during cell division. Unlike their parent genes (which are subject to selection pressure to maintain function), these gene copies do not need to preserve their sequences and may evolve at a relatively faster rate.
Occasionally these regions can be adapted to take on new roles within the organism, becoming novel genes...

Transgenic Plants

8.8K
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...

Genomics

41.0K
Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...

Area of Science:

  • Plant Biology
  • Genomics
  • Bioinformatics

Background:

  • Orphan genes are protein-coding genes without homologs in other species.
  • They play crucial roles in plant environmental responses.
  • Their origins and functions remain poorly understood due to lack of conservation.

Purpose of the Study:

  • To establish the Poaceae Orphan Genes Database (POGD).
  • To provide a user-friendly platform for accessing and analyzing plant orphan genes.
  • To facilitate research on orphan gene origins, functions, and comparative genomics.

Main Methods:

  • Development of a web-based database (POGD).
  • Inclusion of data from four Poaceae species: Brachypodium distachyon, Oryza sativa, Sorghum bicolor, and Zea mays.
  • Integration of gene descriptions, product information, functional annotations, and bioinformatics tools (BLAST, comparative analysis).

Main Results:

  • The POGD provides comprehensive data on plant orphan genes.
  • Includes gene details, sequences, and functional annotations.
  • Offers tools for browsing, searching, and downloading data.

Conclusions:

  • POGD serves as a valuable repository for plant orphan genes.
  • It will aid in understanding orphan gene regulatory mechanisms.
  • The database supports advancements in plant comparative genomics and biology.
