Description
Comprising genetic and phenotypic data from a study of 578 maize inbreds inoculated with Sugarcane Mosaic Virus (SCMV). The study assessed virus symptom presence at 7, 10, 14, 21, 28, and 35 days after inoculation, identifying associations with genomic regions Scmv1 and Scmv2. It was authored by Timothy J. Gustafson and last updated in 2020.
Use Cases
Identify genetic markers for SCMV resistance by analyzing associations between symptom presence at 35 days after inoculation and the Scmv2 genomic region.
Assess the impact of plant growth stage on resistance by comparing symptom development in 69 inbreds inoculated at the three-leaf versus six-leaf stage.
Investigate multigenic resistance by analyzing associations of symptom ratings with loci unlinked to the primary Scmv1 and Scmv2 regions.
Correlate the presence-absence variation (PAV) allele status encompassing Scmv1 with symptom severity ratings across multiple post-inoculation time points.
Strengths
Data is derived from a panel of 578 diverse maize inbreds, providing a substantial sample size for genetic analysis.
Phenotypic assessment includes symptom ratings at six specific time points (7, 10, 14, 21, 28, and 35 days after inoculation), enabling temporal analysis of resistance.
Study identifies specific genomic regions (Scmv1 on chromosome 6 and Scmv2 on chromosome 3) and a downstream SNP associated with SCMV resistance.
Limitations
The dataset is focused on a specific set of inbreds adapted to the northern US Corn Belt, limiting geographic generalizability.
Sample details such as exact column names, file formats, and data structure are unknown, which may complicate initial analysis.
The data is from a single study last updated in 2020 and may not reflect the most recent genetic findings.
