influence of calcium potassium and magnesium on cornus florida l density and resistance to dogwood Anthracnose
2007Co-Authors: Eric J Holzmueller, Shibu Jose, Michael A JenkinsAbstract:Dogwood Anthracnose, a major disease of Cornus florida L., has caused heavy mortality of C. florida in eastern United States forests. Disease severity and rate of infection have been shown to vary with several environmental factors, but the link between soil cation availability and Anthracnose has not been examined. We hypothesized that soil cation availability, particularly calcium (Ca), potassium (K), and magnesium (Mg), would influence dogwood survival from Anthracnose. In forested stands, positive correlations between soil Ca, K, and Mg saturation and C. florida stem density and basal area were found. The effect of these cations at four levels (0, 50, 100, and 200%) of a standard nursery fertilization rate on C. florida seedling survival and resistance to dogwood Anthracnose was tested. Although most of the seedlings died after one season of exposure to dogwood Anthracnose, seedlings that had lower inputs of Ca and K cations showed higher levels of disease severity sooner than seedlings in other treatments, suggesting that these nutrients play a role in C. florida survival from Anthracnose. Magnesium treatment levels did not appear to have an effect on C. florida disease severity or mortality.

colletotrichum lindemuthianum the causal agent of bean Anthracnose
2017Co-Authors: B A Padder, P N Sharma, Halima E Awale, James D KellyAbstract:Common bean (Phaseolus vulgaris L.) is an important constituent of people’s diets especially in developing countries. Dry beans find a suitable position in the culinary items because of their high nutritional value. For instance, rice and bean recipe (Rajmah Chawal) is famous in the northern part of India. Many fungal, viral and bacterial diseases affect the crop and causes heavy losses worldwide. Among the various fungal diseases, bean Anthracnose caused by Colletotrichum lindemuthianum is a serious disease under cool and humid environments. Under favorable conditions, the yield losses may be up to 100 percent. The scientific community across the world has been studying the bean-Anthracnose interaction for over 100 years and the information has helped to understand the pathosystem and devise better disease management strategies. Many excellent reviews on Anthracnose resistance genes, marker aided breeding and R gene signatures highlight different tactics for disease management. Assembling the substantial literature available on pathogen is necessary for better understanding of the pathogen biology. The present review consolidates this information and provides a comprehensive outline about the detection, pathogenicity genes, pathogenic variability and molecular diversity of C. lindemuthianum. The importance of the bean genome and availability of SNP markers to dissect the bean-Anthracnose interface is also addressed.

characterization of the genetic resistance to colletotrichum lindemuthianum in common bean differential cultivars
1996Co-Authors: R A Young, James D KellyAbstract:The inheritance of genetic resistance to bean Anthracnose in genotypes Catrachita and SEL 1360 derived from two Anthracnose differential cultivars, AB 136 and G 2333, respectively, is described. Segregation data from three different F2 populations and their respective F 2:3 families indicated that a single dominant gene is responsible for the Anthracnose resistance in Catrachita. In the test for allelism, chi-square test confirmed that the single dominant resistance gene in Catrachita was situated at a different locus from previously characterized resistance genes A, Are, Mexique 1, Mexique 2, and Mexique 3. It is proposed that the single dominant resistance gene present in Catrachita be assigned the genetic symbol Co-6, Co for Colletotrichum and 6 because it is the sixth major Anthracnose resistance gene characterized and reported in the literature. Segregation in the three F2 populations where SEL 1360 was used as the resistant parent fitted a 3:1 (R-:rr) ratio and a 1:2:1 (RR:Rr:rr) ratio in the F 2:3 families. Segregation data suggested that a single dominant gene was conditioning resistance to Anthracnose in SEL 1360. The test for allelism involving SEL 1360 indicated that the single dominant gene in SEL 1360 is independent from A (Co-1), Are (Co-2), Mexique 1 (Co-3), and Mexique 2 (Co-4) genes. However, the dominant gene in SEL 1360 did not segregate independently from the resistance gene Mexique 3 in the differential cultivar TU, demonstrating that both dominant alleles are located at the same locus. Deployment of major genes of Middle American origin, such as Co-6 and Mexique 3 (Co-5), in different combinations with other characterized genes of Andean origin is possible and should contribute to more durable Anthracnose resistance in common bean.
