Head smut is a systemic disease in maize caused by the soil-borne fungus Sporisorium reilianum that poses a grave threat to maize production worldwide. A major head smut quantitative resistance Cited by: Out of 45, single nucleotide polymorphisms in a panel of inbred lines, 18 novel candidate genes were associated with head smut resistance in maize.

These candidate genes were classified into three groups, namely, resistance genes, disease response genes, and other genes with possible plant disease resistance functions.

ZmWAK, a cell wall-associated receptor kinase, confers quantitative resistance to head smut by: 7. N2 - Head smut, caused by Sphacelotheca reilana (Kühn) Clint, is a disease affecting maize (Zea mays L) in southwest France.

Generation means analysis was used to determine the relative importance of additive, dominance, and epistatic effects controlling resistance of maize to head by: Head smut is a systemic disease in maize caused by the soil-borne fungus Sporisorium reilianum that poses a grave threat to maize production worldwide.

A major head smut quantitative resistance locus, qHSR1, has been detected on maize chromosome bin Here we report the map-based cloning of qHSR1 and the molecular mechanism of qHSR1-mediated Cited by: In another GWAS study with inbred lines, 18 novel candidate genes associated with head smut resistance were identified in maize.

The combination of linkage mapping and association study also appears to be an effective approach in QTL identification for the complex traits, such as disease resistance [14, 18–19]. Experimental materials consisted of maize varieties selected from each decade beginning with the s. These varieties were evaluated for resistance to maize dwarf mosaic virus (MDMV), maize rough dwarf virus (MRDV), common smut disease (CSD) and head smut disease.

Head smut is a systemic disease in maize caused by the soil-borne fungus Sporisorium reilianum that poses a grave threat to maize production worldwide. A major head smut quantitative resistance locus, qHSR1, has been detected on maize chromosome bin Resistance to head smut in in-bred maize lines has been linked to peroxidase activity in coleoptile tissues of infected plants (Zhao et al., ).

Resistant lines exist for sorghum (Miller, ; Wang et al., ). Despite changes in race profiles, no unusual erosion of host plant resistance has occurred (Omer and Frederiksen, ).

Resistance to head smut is a complex quantitative trait that is under polygenic inheritance. Quantitative trait locus (QTL) analyses have located one major consensus QTL for resistance on chromosome 2, in addition to minor QTL identified on all. ZmWAK is the causal gene underlying a major dQTL, Inheritance of resistance to head smut disease in maize book, associated with disease resistance to head smut caused by the fungal pathogen Sphacelotheca reiliana (Zuo et al., ).

qHSR1 had been previously detected on maize chromosome 2 as a dQTL which could reduce head smut disease incidence by ∼25% (Chen et al., ). Abstract: Head smut of maize (Zea mays L.) caused by Sporisorium reliana is an important fungal disease in pment of varieties resistant to this disease is one of the effective approaches to control the disease.

In this study, we mapped and characterized quantitative trait Loci (QTL) conferring resistance to head smut. Head smut, one of the most devastating diseases in maize, causes severe yield losses worldwide. Resistance to head smut has been proven to be a quantitative inherited trait.

In our previous study, a major resistance quantitative trait locus (named qHSR1) was detected on maize chromosome 2 (bin ), and a number of molecular markers have been developed in the qHSR1 region.

Head smut is one of the most devastating diseases in maize, causing severe yield loss worldwide. Here we report identification and fine-mapping of a major quantitative trait locus (QTL) conferring resistance to head smut.

Two inbred lines ‘Ji’ (donor parent, highly resistant) and ‘Huangzao4’ (recurrent parent, highly susceptible) were crossed and then backcrossed to ‘Huangzao4.

Wisser et al. () revealed strong evidences of association between resistance loci for NCLB, head smut, and common rust resistance.

In a fine mapping study, a QTL was found on chromosome 1 conferring resistance to NCLB, Stewart’s wilt (caused by Pantoea stewartii) and common rust (caused by Puccinia sorghi) (Jamann et al., ). Head smut, caused by the fungus Sporisorium reilianum, is a devastating global disease of maize (Zea mays).

In the present study, maize seedlings were artificially inoculated with compatible mating-type strains of S. reilianum by needle inoculation of mesocotyls (NIM) or by soaking inoculation of.

GCA and SCA effects for resistance to stalk rot, ear rot, common smut [Ustilago zeae] and head smut [Sphacelotheca reiliana] were estimated in 15 single hybrids from a diallel cross of 6 inbred maize lines.

Data are tabulated. Results were taken to indicate the importance of additive gene action for disease resistance in the inbreds used. Here is a list of seventeen major diseases that are found in maize: 1. Smut Diseases 2.

Virus Diseases 3. Downy Mildews Disease 4. Brown Spot Disease 5. Stalk Rot Disease 6. Pre-Flowering Stalk Rot Disease 7. Pythium Stalk Rot Disease 8. Post-Flowering Stalk Rot Disease 9. Charcoal Rot Disease Black Bundle Disease Cob Rots Disease   A major resistance QTL, qHSR1, on bin confers resistance to head smut, one of the most disastrous diseases in maize (Chen et al., ).

The qHSR1 was introduced via marker-assisted backcrossing into 10 maize inbred lines that have high yield potential but are susceptible to head smut. Head smut is a soil-borne systemic maize disease caused by the causal pathogen Sporisorium reiliana.

ZmWAK is the gene within the major QTL qHSR1 conferring resistance to head smut disease. Inheritance of resistance to head smut disease in maize (Zea mays L.). Summary — Head smut, caused by Sphacelotheca reilana (Kühn) Clint, is a disease affecting maize (Zea mays L) in southwest France.

Generation means analysis was used to determine the relative importance of additive, dominance, and epistatic effects controlling resistance of maize to head smut. In book: Genome Wide Association Study (GWAS) on Disease Resistance in Maize, Publisher: Springer, Cham, pp approach for identifying causal genetic factors for head smut resistance in.

Head smut of maize is a kind of worldwide disease. Development of resistant varieties is an effective choice to control the disease, which depends on the knowledge of the resistance resources and genetic mechanism.

In order to select and breed resistant varieties, some resistant resources of head smut have been selected. The reciprocal-cross differences for resistance to head-smut disease in maize were studied in the field in the crosses of "N6", a resistant inbred line of dent type, with two susceptible inbred lines of sweet type, "SD-1" and "SM7".

In both the crosses, "N6" × "SD-1" and "N6" × "SM 7", the populations of F1, F2, BCr (backcrosses to resistant parent), BCS (backcrosses to susceptible parent. ring resistance to anthracnose stalk rot), Rxo1 (a maize NLR gene conferring resistance to bacterial streak disease in rice), ZmWAK (a wall-associated receptor–like kinase gene underlying a major QTL conferring resistance to head smut), Htn1 (a wall-associated receptor–like kinase gene conferring quantitative resistance to NLB).

Maize head smut is an important disease in many major maize growing regions around the world. In maize head smut caused the loss of 38, tons of maize in the U.S. and Canada (Mueller and Wise, ). The disease is easily spread by its durable teliospores that.

Northern leaf blight (NLB) and head smut are two important diseases of maize (Zea mays) in China. The use of resistant cultivars is the most effective, economical and environmentally friendly means to cope with these diseases. For combining alleles for resistance to both NLB and head smut, parental inbred Ent17 with NLB resistance and parental inbred Ent12 with head smut resistance were.

Inheritance of Maize Common Smut Resistance. If resistance was selectively neutral in the absence of disease, recurrent selection would not have changed the level of resistance. However, mean. The result revealed that lines carrying Ht1, Ht2 and head smut QTL had resistance level and yield over donor Ent17, Ent12, lines carrying Ht1 and Ht2, and lines carrying Ht1 and head smut QTL, suggesting that marker assisted-selection strategy can be used effectively to select high yielding and resistance level in breeding materials in maize.

3 Seminal Disease Resistance Genetic Studies in Maize As is made clear in this book, maize has been an important model species for man y aspects of plant genetics. Disease resistance is no exception.

Some key discoveries in the area of disease resistance genetics and resistance gene function that have been made in maize are listed below. Necrosis and disease development is most prevalent on the head of the infected host.

Environment. Maize head smut occurs in most maize-growing areas, including many regions of North America, Australia, Asia, and southern Europe.

It causes tremendous loss of yield during outbreaks due to the replacement of the ear with large smut sori. Z.H. Wang's 5 research works with 84 citations and reads, including: Analysis of QTL for resistance to head smut (Sporisorium reiliana) in maize. However, other studies found no effect of BXs on fungal disease resistance, including maize stalk rot, southern corn leaf blight, maize anthracnose, corn smut and head blight (Niemeyer, ).

Recently, Exserohilum turcicum, the causal agent of NCLB, has been shown to elicit apoplastic BXs accumulation at the early infection stages (Ahmad et.

to cause smut disease on maize. New fungal diseases emerge as a result of host switching events and host range extensions of phytopathogenic fungi (Friesen et al., ; Giraud et al., ). It is thought that the original host of S. reilianum was sorghum and that the disease only later spread to.

Maize (Zea mays L.) is grown on 15 million ha in eastern and southern l diseases are of common occurrence in the region and regularly result in significant yield losses. A collaborative regional disease nursery (REGNUR) project was initiated in to identify and increase access to disease resistant germplasm, generate and disseminate information on disease and insect resistance.
