AI Article Synopsis
- Symbiotic fungi of the genus positively influence the growth and disease resistance of various plants, but their molecular interactions are not well understood.
- This study examines the gene expression changes in two quinoa cultivars when co-cultivated with specific fungal strains (BOL-12 and T22) using RNA sequencing and RT-qPCR.
- The cultivar Kurmi shows a significant activation of defense-related genes, particularly germin-like genes, compared to the Real cultivar, indicating that different quinoa cultivars have distinct responses to these fungal interactions.
Article Abstract
Symbiotic strains of fungi in the genus affect growth and pathogen resistance of many plant species, but the interaction is not known in molecular detail. Here we describe the transcriptomic response of two cultivars of the crop to axenic co-cultivation with BOL-12 and T22. The response of roots to BOL-12 and T22 in the early phases of interaction was studied by RNA sequencing and RT-qPCR verification. Interaction with the two fungal strains induced partially overlapping gene expression responses. Comparing the two plant genotypes, a broad spectrum of putative quinoa defense genes were found activated in the cultivar Kurmi but not in the Real cultivar. In cultivar Kurmi, relatively small effects were observed for classical pathogen response pathways but instead a -specific clade of germin-like genes were activated. Germin-like genes were found to be more rapidly induced in cultivar Kurmi as compared to Real. The same germin-like genes were found to also be upregulated systemically in the leaves. No strong correlation was observed between any of the known hormone-mediated defense response pathways and any of the quinoa- interactions. The differences in responses are relevant for the capabilities of applying agents for crop protection of different cultivars of .

Article Synopsis
- Downy mildew, caused by a specific type of microorganism, poses a major threat to quinoa farming in the Andes and globally, yet no molecular studies have been conducted on this interaction.
- Researchers developed methods to examine quinoa's response to downy mildew at the gene expression level, isolating and maintaining the pathogen to track disease progression in different quinoa varieties.
- Findings showed that one quinoa variety, Kurmi, exhibited slower disease progression and better tolerance compared to another variety, Maniqueña Real, with specific defense genes being significantly activated in response to infection, indicating potential markers for breeding more disease-resistant quinoa.
