Variation for neutral markers is correlated with variation for quantitative traits in the plant pathogenic fungus Mycosphaerella graminicola

, : Variation for neutral markers is correlated with variation for quantitative traits in the plant pathogenic fungus Mycosphaerella graminicola. Molecular Ecology 14(9): 2683-2693

We compared genetic variation and population differentiation at RFLP marker loci with seven quantitative characters including fungicide resistance, temperature sensitivity, pycnidial size, pycnidial density, colony size, percentage of leaves covered by pycnidia (PLACP) and percentage of leaves covered by lesions (PLACL) in Mycosphaerella graminicola populations sampled from four regions. Wide variation in population differentiation was found across the quantitative traits assayed. Fungicide resistance, temperature sensitivity, and PLACP displayed a significantly higher QST than GST, consistent with selection for local adaptation, while pycnidial size, pycnidial density and colony size displayed a lower or significantly lower QST than GST, consistent with constraining selection. There was not a statistical difference between QST and GST in PLACL. We also found a positive and significant correlation between genetic variation in molecular marker loci and quantitative traits at the multitrait scale, suggesting that estimates of overall genetic variation for quantitative traits in M. graminicola could be derived from analysis of the molecular genetic markers.

The herbicide pyrazon (5-amino-4-chloro-2-phenyl-3 (2H)-pyridazinone) was readily metabolized to the N-glucosyl derivative of pyrazon in the tolerant red-beet cultivar Detroit Dark Red but was not metabolized in eight susceptible species.
