Marker-Assisted Selection of Novel Bacteria Contributing to Soil-Borne Plant Disease Suppression
نویسندگان
چکیده
It is well established that some bacteria can suppress plant diseases through the expression of multiple mechanisms, including the direct inhibition of plant pathogens and the indirect induction of plant host resistance pathways (Kim et al., 2011). Because of this, microbes that form close associations with plants are the primary source of active ingredients in biopesticides for the control of plant diseases. But for over a decade now, molecular techniques have provided a glimpse of the diversity of soiland plant-associated microbes and the factors controlling their diversity and plant disease suppressing activities.

The effect of different compost-soil ratios on the incidence of Pythium aphanidermatum causing tomato damping off was tested in a greenhouse experiment. The inoculum density of 5% was determined to be suitable for inoculation in compost experiments based on investigations of disease incidence with 5, 10 and 20% inoculum densities. To evaluate the effect of compost on incidence of tomato damping...
متن کاملSNP Marker Assisted Selection for Identification of Fusarium Resistant Melon Plants
Melon is an important crop cultivated in moderate climate regions of the world. One of the most important diseases of this plant is vascular wilt caused by Fusarium oxysporum f.sp. melonis (Fom). Infection of farm by this pathogen can result in huge damage around the world. Development of resistant varieties is the most effective method for disease control. Four races of 0, 1, 2 and 1,2 have be...
متن کاملMarker assisted selection for the improvement of Sarjoo-52 for drought tolerance by introgression of MQTL1.1 from the source Nagina–22
Literatures have reported that a lot of drought related genes were cloned and individual gene showed positive effects under controlled stress experiments, but were not much effective in the field. Although, the progresses by conventional breeding approaches were achievable as some drought varieties have been released to the farmers in the recent years but this is not adequate to cope up with th...
متن کاملLinking sequence to function in soil bacteria: sequence-directed isolation of novel bacteria contributing to soilborne plant disease suppression.
Microbial community profiling of samples differing in a specific ecological function, i.e., soilborne plant disease suppression, can be used to mark, recover, and ultimately identify the bacteria responsible for that specific function. Previously, several terminal restriction fragments (TRF) of 16S rRNA genes were statistically associated with damping-off disease suppression. This work presents...
متن کاملFungal Community Structure in Disease Suppressive Soils Assessed by 28S LSU Gene Sequencing
Natural biological suppression of soil-borne diseases is a function of the activity and composition of soil microbial communities. Soil microbe and phytopathogen interactions can occur prior to crop sowing and/or in the rhizosphere, subsequently influencing both plant growth and productivity. Research on suppressive microbial communities has concentrated on bacteria although fungi can also infl...
