Biochemical methods for control of cereal crop resistance to biotic and abiotic factors

摘要

One of factors of achieving productivity of new cereal crop cultivars is their resistance to biotic and abiotic factors in the environment. To develop resistant cultivars it is important to know the mechanisms of plant resistance, and to have effective and definitive methods for the prediction and selection of resistant genotypes of such cereal crops. It is thought that glycoproteins (such as lectins and proteinase inhibitors) may have an important role in plant resistance mechanisms (Iljinskaja, 1991). It is known that these proteins protect a plant from attack by insects and pathogens, and that their contents in the grain are genetically determined. Further, a certain role in the regulation of plant responses to different natural stress factors belongs to salicylic acid (Raskin, 1992). Salicylic acid may be a trigger that activates plant protection mechanisms in response to diseases and abiotic stresses
