Tolerance of plant virus disease: Its genetic, physiological, and epidemiological significance

Abstract The development and use of tolerance have been proposed as an alternative or complementary method to host resistance in the management plant diseases, including those caused by viruses. There has much ambiguity among pathologists, breeders, agronomists meaning how it can be operationally defined, but a modern consensus seems emerged. Tolerance is relative term that means limited reduction fitness (reproduction survival) relation pathogen load throughout during defined period growth such reproductive stage. This emphasizes need study stage disease tolerance. Despite this apparent consensus, there remain questions over model systems, genetic background tolerance, its physiological expression, epidemiological consequences deployment crops, comparison with resistance. Most examples reviewed here are for virus although other taxa referred to, natural phenomenon wild plants crop relatives. An argument made studying commonalities interactions responses biotic abiotic stressors; particular, whether infection mitigate impact heat, cold, drought salinity stress plants. Finally, we review mathematical models evaluating strategy using management.

Diversity, Community Structure, and Potential Functions of Root-Associated Bacterial Communities of Different Wheat (Triticum aestivum) Cultivars under Field Conditions

Agronomy, Journal Year: 2023, Volume and Issue: 13(5), P. 1392 - 1392

The wheat (Triticum aestivum) microbiome is essential to its growth and adaptation under the current climatic crisis. Wheat breeding programs are often mainly focused on obtaining more resistant cultivars; thus, plant genotype-by-microbiome interactions have gained attention. In this sense, local cultivars represent a unique opportunity examine how bacterial communities recruited support field conditions. study, we explored diversity, community structure, potential functions of root-associated four Chilean conditions through Illumina MiSeq. Analyses showed that Proteobacteria was most abundant phylum in root endosphere (51.1 74.4%) rhizosphere samples (39.3 44.9%) across cultivars. Significant differences (p ≤ 0.05) alpha beta diversity were observed samples, independently genotypes. Potassium identified as main factor driving microbiomes wheat. A higher proportion shared operational taxonomic units (OTUs) found (mainly Pseudomonas, Flavobacterium, Janthinobacterium) compared with (dominated by Delftia, Acinetobacter, Stenotrophomonas, Kaistobacter) all larger predicted functional activities revealed chemoheterotrophy aerobic environment, whereas among minor functions, nitrogen cycling trait, related samples. co-occurrence analysis complex cultivars’ niche identifying three (Comamonadaceae, Enterobacteraceae, Micrococcaceae) (Corynebacteraceae, Dermabacteraceae, Xanthomonadaceae, Staphylococcaceae) families keystone taxa for rhizosphere, respectively. It suggested such findings associated would help develop new abilities recruit specific communities.
