The Maize Lethal Leaf Spot 1 Mutant Has Elevated Resistance to Fungal Infection at the Leaf Epidermis

Bayesian inference to study genetic control of resistance to gray leaf spot in maize.

Gray leaf spot (GLS) is a major maize disease in Brazil that significantly affects grain production. We used Bayesian inference to investigate the nature and magnitude of gene effects related to GLS resistance by evaluation of contrasting lines and segregating populations. The experiment was arranged in a randomized block design with three replications and the mean values were analyzed us...

Species of Cercospora associated with grey leaf spot of maize

Grey leaf spot is a serious yield-reducing disease of maize (Zea mays) in many parts of the world where this crop is cultivated. The causal organism associated with the disease is Cercospora zeae-maydis. Two potential sibling species have been recognized as Groups I and II. The DNA sequences for the internal transcribed spacers (ITS1 & ITS2), the 5.8S rRNA gene, elongation factor 1-alpha, histo...

OCCURRENCE OF NORTHERN LEAF BLIGHT, Phaeosphaeria LEAF SPOT , SOUTHERN LEAF BLIGHT, RUST AND MAIZE STREAK VIRUS IN KENYA

Balancing division and expansion during maize leaf morphogenesis: analysis of the mutant, warty-1.

Cell division and expansion are growth events that contribute to the developing shape, or morphogenesis, of a plant. Division and expansion are coordinated to the extent that plant organs, such as leaves, generally portray a predictable cellular pattern. To dissect the relationship between division and expansion, and to test for the role of each during morphogenesis, we have identified a recess...

Mycosphaerella leaf spot diseases

By the end of the 1980s, black leaf streak disease caused by Mycosphaerella fijiensis was present in all continents where bananas or plantains were grown, although distribution in some regions was limited to a few countries. In this presentation, the spread of the disease during the 1990s in several countries and regions, and the important socio-economic consequences are discussed. From 1990 to...
