EFFECT OF TEMPERATURE ON THE INTERACTION BETWEEN BLACK ROOT ROT (Thielaviopsis basicola) AND THE ROOT KNOT NEMATODE (Meloidogyne incognita)
Both the root-knot nematode (Meloidogyne incognita) and the soilborne fungus that causes black root rot of seedling cotton (Thielaviopsis basicola) are widely distributed in cotton field soils in Arkansas. Both of these pathogens are capable of causing significant crop damage and yield loss, primarily through damage to the root systems of infected plants. When root-knot nematode or T. basicola ...
متن کاملChanges in Root Architecture Caused by Meloidogyne incognita and Thielaviopsis basicola and Their Interaction on Cotton
The root system is vital for the cotton plant to absorb nutrients and water from the soil and to anchor the plant. Two important soil-borne pathogens of cotton, Meloidogyne incognita (root-knot nematode), and Thielaviopsis basicola can adversely affect root systems resulting in suppressed growth and less efficient water and nutrient uptake and transport. In fields where these pathogens occur to...
متن کاملA Pictorial Disease Severity Key and the Relationship Between Severity and Incidence for Black Root Rot of Pansy Caused by Thielaviopsis basicola
Black root rot of pansy (Viola × wittrockiana Gams ex Kappert) is caused by Thielaviopsis basicola (Berk. & Broome) Ferraris. The synanamorph of T. basicola is Chalara elegans Nag Raj & Kendrick. Black root rot and Thielaviopsis root rot are common names used for disease caused by the same pathogen on multiple ornamental and agricultural crops (14,16). The macroscopic appearance of the disease ...
متن کاملInitial Cellular Interactions Between Thielaviopsis basicola and Tobacco Root Hairs.
ABSTRACT Cellular events that occur during the initial interactions between Thielaviopsis basicola and root hairs of tobacco (Nicotiana tabacum) were examined microscopically. Time-course documentation of the infection process indicated a dynamic interaction between T. basicola and the living host cell. Upon root hair contact and recognition, the vegetative apex of T. basicola rapidly different...
متن کاملFirst Report of Root Rot Caused by Plectosphaerella cucumerina on Cabbage in China
Severe root rot was observed in fields of cabbages (Brassica oleracea L.) in 2015 in China. Cardinal symptoms of this disease included root rot and wilting leaves. A fungus was isolated from diseased tissues consistently. Based on the morphological features and molecular analysis of the ITS-5.8S rDNA and D1/D2 domain of the 28S rRNA gene, it was identified as Plectosphaerella cucumerina. This i...
