Molecular markers

Molecular markers are specific DNA sequences within a plant’s genome that are used to identify and track genetic traits. These markers serve as signposts, allowing scientists to locate specific genes associated with desirable traits, such as disease resistance or higher yield. Types of molecular markers include RFLPs, AFLPs, SSRs, and SNPs, each offering unique benefits in terms of accuracy and ease of use. Molecular markers are widely applied in plant breeding programs for marker-assisted selection (MAS), enabling breeders to develop new crop varieties with precision and efficiency. They also aid in understanding genetic relationships among plant species, enhancing conservation efforts and enabling better management of plant genetic resources. Molecular markers continue to be a cornerstone in modern plant biotechnology and genetic research.
