Introgression of bacterial leaf blight (BLB) resistant gene, Xa7 into MARDI elite variety, MR219 by marker assisted backcrossing (MABC) approach

Braz. j. biol; 84 (), 2024
Abstract Bacterial leaf blight (BLB) is one of the major rice diseases in Malaysia. This disease causes substantial yield loss as high as 70%. Development of rice varieties which inherited BLB resistant traits is a crucial approach to promote and sustain rice industry in Malaysia. Hence, this study aims ...

Characterization of wheat-Thinopyrum bessarabicum genetic stock for stripe rust and Karnal bunt resistance

Braz. j. biol; 83 (), 2023
Abstract Utilization of modern breeding techniques for developing high yielding and uniform plant types ultimately narrowing the genetic makeup of most crops. Narrowed genetic makeup of these crops has made them vulnerable towards disease and insect epidemics. For sustainable crop production, genetic var...

Fructosan form Paenibacillus kribbensis PS04 enhance disease resistance against Rhizoctonia solani and tobacco mosaic virus

BACKGROUND: Rice sheath blight (caused by Rhizoctonia solani) and tobacco mosaic virus are very important plant diseases, causing a huge loss in global crop production. Paenibacillus kribbensis PS04 is a broad-spectrum biocontrol agent, used for controlling these diseases. Previously, extracellular polys...

Identificación de marcadores moleculares (SNP) y genes candidatos asociados a la tolerancia genética al complejo mancha de asfalto en variedades nativas de maíz (Zea mays L)

Cienc. tecnol. salud; 7 (2), 2020
El complejo mancha de asfalto (CMA) en maíz (ZeamaysL.), causado por los hongos Phyllachora maydis Maubl. Y Monographella maydis Müller & Samuels, es una enfermedad de importancia económica en Guatemala, que ha causado pérdida en el rendimiento entre 30 a 50%, inclusive del 100% si las condiciones so...

Transcriptome and proteome analyses of resistant preharvest peanut seed coat in response to Aspergillus flavus infection

BACKGROUND: The infection of peanut (Arachis hypogaea L.) seed coat by the pathogenic fungus Aspergillus flavus has highly negative economic and health impacts. However, the molecular mechanism underlying such defense response remains poorly understood. This study aims to address this issue by profiling ...

Identification of groundnut (Arachis hypogaea) SSR markers suitable for multiple resistance traits QTL mapping in African germplasm

Electron. j. biotechnol; 18 (2), 2015
Background This study aimed to identify and select informative Simple Sequence Repeat (SSR) markers that may be linked to resistance to important groundnut diseases such as Early Leaf Spot, Groundnut Rosette Disease, rust and aflatoxin contamination. To this end, 799 markers were screened across 16 farme...

Analysis of gene expression profiles in response to Sporisorium reilianum f. sp. zeae in maize (Zea mays L.)

Electron. j. biotechnol; 17 (5), 2014
Background Head smut of maize, which is caused by Sporisorium reilianum f. sp. zeae (Kühn), is a serious disease in maize. In order to reveal the molecular mechanism of the resistance to head smut in maize, a microarray containing ~ 14,850 probes was used to monitor the gene expression profiles between ...

Data mining and influential analysis of gene expression data for plant resistance gene identification in tomato (Solanum lycopersicum)

Electron. j. biotechnol; 17 (2), 2014
Background Molecular mechanisms of plant-pathogen interactions have been studied thoroughly but much about them is still unknown. A better understanding of these mechanisms and the detection of new resistance genes can improve crop production and food supply. Extracting this knowledge from available geno...
