Comparative survival of Sclerotia of Sclerotinia minor and S. sclerotiorum.
Survival of sclerotia of Sclerotinia minor and S. sclerotiorum was compared in irrigated fields during the summer in two major lettuce production areas in California. More than 50% sclerotia of S. sclerotiorum compared with 4 and 35% of S. minor remained viable after 24 weeks of burial at 15 and 5 cm depths, respectively, in the San Joaquin Valley while >80% of sclerotia survived in the Salinas...
متن کاملSynthesis and localization of a development-specific protein in sclerotia of Sclerotinia sclerotiorum.
A development-specific protein (SSP) makes up about 35 to 40% of the total protein in sclerotia of the fungus Sclerotinia sclerotiorum. The protein consists of three charge isomers, with one isomer making up 80 to 90% of the total. In vitro translation of poly(A)+ RNA isolated from cells in early stages of sclerotia formation revealed that 44% of the amino acids incorporated was into SSP. In vi...
متن کاملTime and burial depth influencing the viability and bacterial colonization of sclerotia of Sclerotinia sclerotiorum
Sclerotia are the primary over wintering inoculum of Sclerotinia sclerotiorum (Lib.) de Bary. The effects of tillage on the primary inoculum are not well understood. The purpose of this research was to study sclerotial viability over time and between burial depths in soil, to identify bacteria colonizing and degrading the sclerotia, and determine whether these bacteria may be utilized as biolog...
متن کاملConiothyrium minitans survival in soil and ability to infect sclerotia of Sclerotinia sclerotiorum
Survival of the sclerotial parasite Coniothyrium minitans in soil, when applied as spore suspension or colonised solid substrate (maizemeal-perlite) inocula, and ability to infect Sclerotinia sclerotiorum sclerotia incorporated into the soil after different times was assessed over 6 months. Unambiguous detection of the C. minitans isolate from the indigenous C. minitans soil population was achi...
متن کاملAntagonism of Aspergillus Terreus to Sclerotinia Sclerotiorum
An Aspergillus terreus strain showed in vitro antagonistic activity against the plant pathogen Sclerotinia sclerotiorum (Lib.) de Bary. The interaction between A. terreus and sclerotia revealed that the mycoparasite sporulated abundantly on the sclerotial surface. Cell breakdown due to host cell wall disruption was observed in inner rind cells, by a scanning electron microscopy.
