Genome-wide nested association mapping of quantitative resistance to northern leaf blight in maize.
Quantitative resistance to plant pathogens, controlled by multiple loci of small effect, is important for food production, food security, and food safety but is poorly understood. To gain insights into the genetic architecture of quantitative resistance in maize, we evaluated a 5,000-inbred-line nested association mapping population for resistance to northern leaf blight, a maize disease of glo...
متن کاملFlavonoid phytoalexin-dependent resistance to anthracnose leaf blight requires a functional yellow seed1 in Sorghum bicolor.
In Sorghum bicolor, a group of phytoalexins are induced at the site of infection by Colletotrichum sublineolum, the anthracnose fungus. These compounds, classified as 3-deoxyanthocyanidins, have structural similarities to the precursors of phlobaphenes. Sorghum yellow seed1 (y1) encodes a MYB transcription factor that regulates phlobaphene biosynthesis. Using the candystripe1 transposon mutagen...
متن کاملAnalysis of Digenic Epistatic and QTL × Environment Interactions for Resistance to Banded Leaf and Sheath Blight in Maize (Zea mays)
Maize banded leaf and sheath blight (BLSB) due to Rhizoctonia solani Kühn, is an increasing problem in maize production areas, particularly in China and Southeast of Asian. A genetic map containing 146 simple sequence repeat (SSR) markers and 229 F2 plants derived from the cross R 15 (resistant) × Ye 478 (susceptible) were used in this study. QTL were characterized in a population of 229 F2:4 l...
متن کاملSIMPLE SEQUENCE REPEAT MARKERS ASSOCIATED WITH ANTHRACNOSE AND Turcicum LEAF BLIGHT RESISTANCE IN SORGHUM
Deployment of host resistance remains the most cost effective strategy for management of foliar and grain diseases, especially for resource constrained farmers. There is paucity of information on dual resistance in sorghum to both diseases. The objective of this study was to identify SSR markers associated with anthracnose and TLB resistance in sorghum for future use in markers assisted introgr...
متن کاملMapping Quantitative Trait Loci (QTL) for Resistance to Late Blight in Tomato
Late blight caused by Phytophthora infestans (Montagne, Bary) is a devastating disease of tomato worldwide. There are three known major genes, Ph-1, Ph-2, and Ph-3, conferring resistance to late blight. In addition to these three genes, it is also believed that there are additional factors or quantitative trait loci (QTL) conferring resistance to late blight. Precise molecular mapping of all th...
