Plant Breeding and Biotechnology

19.7K
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.

Transgenic Plants

7.4K
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...

Genetic Variation01:25

Genetic Variation

368
Genetic variation is the diversity in DNA sequences found among individuals of the same species. This diversity is crucial for a species' survival because it helps organisms adapt to environmental changes. Genetic variation begins with fertilization, where an egg and sperm cell merge. Each of these cells carries 23 chromosomes, up to 46 in the fertilized egg. Chromosomes are long DNA strands that contain genes, the basic units of heredity.
Genes exist in different versions called alleles,...

Genome Size and the Evolution of New Genes

8.1K
While every living organism has a genome of some kind (be it RNA, or DNA), there is considerable variation in the sizes of these blueprints. One major factor that impacts genome size is whether the organism is prokaryotic or eukaryotic. In prokaryotes, the genome contains little to no non-coding sequence, such that genes are tightly clustered in groups or operons sequentially along the chromosome. Conversely, the genes in eukaryotes are punctuated by long stretches of non-coding sequence.

Area of Science:

  • Agricultural Science
  • Plant Genetics
  • Crop Improvement

Background:

  • Legumes, particularly chickpeas, offer substantial human nutrition and soil benefits but face limited genetic improvement.
  • Narrow genetic bases, biotic/abiotic stresses, and climate change hinder chickpea advancement compared to cereals.
  • There is a critical need for advanced breeding strategies to enhance chickpea yield, resilience, and nutritional value.

Approach:

  • Utilizing wild chickpea relatives and advanced breeding methods to broaden the genetic base.
  • Employing 'Omics' sciences (genomics, transcriptomics) and high-throughput phenotyping for trait discovery.
  • Implementing advanced molecular techniques like next-generation sequencing, SNP genotyping, and whole-genome re-sequencing.

Key Points:

  • Identification of desirable trait donors within cultivated and wild chickpea germplasm.
  • Development of methods for inter-specific hybridization and gene introgression from wild *Cicer* species.
  • Successful application of diverse molecular markers and genotyping platforms for QTL mapping and trait analysis.

Conclusions:

  • Advanced breeding approaches and 'Omics' technologies are crucial for overcoming chickpea genetic limitations.
  • These strategies effectively broaden the narrow genetic base of chickpea germplasm.
  • The research paves the way for developing climate-resilient, high-yielding, and nutritionally enhanced chickpea cultivars.
