“Phylogenetics: Models and Applications in Crop Improvement”

  Deleterious effects of climate and human activities, as well as diverse environmental stresses, present critical challenges to agriculture production. These challenges could be addressed by the development of crop varieties with increased biotic and abiotic resistance. However, considering the diverse interactions between crops and environmental factors, it is surprising that evolutionary principles have been underexploited in addressing these challenges. The quest to understand the interconnectedness of life has captivated humankind for centuries. Phylogenetics is the science of reconstructing the evolutionary history of organisms. The field of phylogenetics continues to evolve at a rapid pace. New technologies like next-generation sequencing and advanced computational tools promise even deeper insights into the intricate web of life.

The construction of a phylogenetic tree is based on different methods like distance and trait-based methods. Nevertheless, different models are also used additionally to explain the evolutionary pathway of species. The future of phylogenetics in addition to many omics and strong experimental protocols and data interpretation can greatly contribute to resolving the tree of life. For the construction of a phylogenetic tree either morphological traits or DNA or amino acid data or even organellar DNA can also be used2.

Phylogenetic analysis conducted by rDNA-ITS region in Capsicum shows C. annuum shows lower genetic diversity compared to other clades and they can be used for identification of domesticated species of capscicum3.

In conclusion, phylogenetics is not just a scientific tool for breeders, but a powerful ally in the quest for better varieties. By understanding the evolutionary history of a crop and its wild relatives, we can unlock a treasure trove of hidden potential, paving the way for a future where crop varieties continue to nourish generations to come1.
