Development CRISPR/CAS9-mediated resistance in sunflower against O. cumana

Abstract

Sesquiterpene lactones (STL) are a group of natural compounds found in various plant species, including sunflowers (Helianthus spp.), and they have been studied for their potential role in allelopathy and defense against pests and pathogens. Allelopathy refers to the ability of certain plants to release chemicals that affect the growth and development of neighboring plants and organisms. In the context of sunflower broomrape (Orobanche cumana) and sunflowers, STLs have been of particular interest due to their potential role in inhibiting the growth of the broomrape parasite. Some STLs have been shown to possess allelopathic properties, which means they can influence the germination and growth of other plants, potentially including parasitic plants like sunflower broomrape. Research has suggested that certain STLs found in sunflowers may exhibit inhibitory effects on the germination and growth of sunflower broomrape seeds. These compounds could potentially be released from the sunflower roots and into the soil, creating a hostile environment for the parasite. However, the effectiveness of sesquiterpene lactones in controlling sunflower broomrape is still an active area of research, and their practical application as a management strategy requires further investigation.
