Plant Breeding and Biotechnology

20.6K
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.

The central dogma explains the flow of genetic information from DNA nucleotides to the amino acid sequence of proteins.
RNA is the Missing Link Between DNA and Proteins
In the early 1900s, scientists discovered that DNA stores all the information needed for cellular functions and that proteins perform most of these functions. However, the mechanisms of converting genetic information into functional proteins remained unknown for many years. Initially, it was believed that a single gene is...

Genomics

38.7K
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...

Background:

  • Wheat is a crucial global food source, but its yield is significantly impacted by environmental stresses, biotic and abiotic factors, and heavy metals.
  • Traditional breeding methods have limitations in enhancing wheat yield to meet global demands.
  • Understanding the molecular basis of stress responses is vital for developing resilient wheat varieties.

Purpose of the Study:

  • To review and discuss the application of omics technologies and genome editing for improving wheat stress resilience.
  • To highlight the potential of integrated omics approaches in identifying genes and pathways associated with stress tolerance.
  • To explore novel research directions, including viroid discovery and its implications.

Main Methods:

  • Review of current literature on omics technologies (proteomics, metabolomics, transcriptomics, genomics) and their application in wheat.
  • Discussion of genome editing tools such as CRISPR-Cas9 and CRISPR-Cas13 for genetic engineering.
  • Exploration of comparative genomics and high-performance phenotyping for stress resilience studies.

Main Results:
