Application of Quantitative Trait Loci (QTL) mapping to study the interactions of pea (Pisum sativum L.) with rhizosphere microorganisms

Abstract

The review is devoted to the application of quantitative trait loci (QTL) analysis to study the interactions of common pea (Pisum sativum L.), one of the most important grain legumes, with soil microorganisms. Pea, like other legumes, forms symbioses with nodule bacteria and arbuscular mycorrhiza fungi. The formation of symbioses leads to improved nitrogen and phosphorus nutrition of plants, resulting in increased plant resistance to abiotic and biotic stress factors, in particular, to phytopathogens. The main objective of QTL analysis is to identify genomic regions whose allelic state affects the manifestation of quantitative traits, including such traits as nitrogen fixation efficiency and pathogen resistance. The identified QTLs and molecular markers created on their basis can be used in the selection of new pea varieties with improved agronomic characteristics, such as resistance to changing environmental conditions and high efficiency of symbiotic systems. This article reviews the historical stages of the emergence of QTL analysis, the basic principles of QTL mapping, and modern approaches. The need for an integrated approach to the analysis of the characteristics of symbiosis efficiency and stability is noted, and the use of integrated phenotypic assessments for working with such traits is discussed.
