Mapping of resistance genes to Puccinia polysora in maize The objectives of this study were to identify microsatellite markers linked to resistance gene of resistance to Puccinia polysora and to estimate the phenotypic effect of these genes on two monocyclic variables lesion, number and length. Two inbreed lines with different degrees of resistance (Z-95 and Z-93), the hybrid (Z-95 X Z-93) and ...

Grain length (GL) is one of the crucial determinants rice yield and quality. However, there still a shortage knowledge on major genes controlling inheritance GL in japonica rice, which severely limits improvement yields. Here, we systemically measured 667 F2 1570 BC3F3 individuals derived from two cultivated cultivars, Pin20 Songjing15, order to identify genomic regions associated with GL. A no...

Abstract Background Cucumber ( Cucumis sativus L.) is cultivated worldwide, and it essential to produce enough high-quality seeds meet demand. Pre-harvest sprouting (PHS) in cucumber a critical problem causes serious damage seed production quality. Nevertheless, the genetic basis molecular mechanisms underlying PHS remain unclear. QTL-seq an efficient approach for rapid quantitative trait loci ...

Zinc (Zn) is an essential element for plant growth and development, and Zn derived from crop plants in the diet is also important for human health. Here, we report that genetic variation in Heavy Metal-ATPase 4 (HMA4) controls natural variation in leaf Zn content. Investigation of the natural variation in leaf Zn content in a world-wide collection of 349 Arabidopsis thaliana wild collected acce...

Sorghum is one of the most promising bioenergy crops. Stem juice yield, together with stem sugar concentration, determines sugar yield in sweet sorghum. Bulked segregant analysis (BSA) is a gene mapping technique for identifying genomic regions containing genetic loci affecting a trait of interest that when combined with deep sequencing could effectively accelerate the gene mapping process. In ...

Host plant resistance has been widely used for controlling the major rice pest brown planthopper (BPH, Nilaparvata lugens). However, adaptation of the wild BPH population to resistance limits the effective use of resistant rice varieties. Quantitative trait locus (QTL) analysis was conducted to identify resistance-breaking genes against the anti-feeding mechanism mediated by the rice resistance...

Cucumber is a widely grown vegetable crop plant and host to many different pathogens. vein yellowing virus (CVYV) causes economic losses on cucumber crops in Mediterranean countries some part of India such as West Bengal African Sudan. CVYV an RNA potyvirus transmitted mechanically by whitefly ( Bemisia tabaci ) semipersistent manner. Control this heavily dependent the management insect vector ...

This study was carried out to evaluate the genetic effect of quantitative trait loci (QTLs) conferring drought tolerance in wheat. A population of 120 F(2) individuals from the cross between the drought-tolerant S-78-11 and drought-sensitive Tajan cultivars were analyzed for their segregation under drought stress conditions. The relative water content under drought stress conditions exhibi...
