    摘要: 一种大量产生稻瘟病菌有性世代的分生孢子涂布法,包括1)制备稻瘟病菌不同交配型的分生孢子悬浮液;2)在燕麦培养基上按比例涂布不同交配型的分生孢子悬浮液;3)在培养条件下获得大量稻瘟病菌子囊和子囊孢子。该方法解决了传统现有技术对峙培养法产生有性世代子囊壳和子囊孢子的总量少、不稳定、样品间差异大、有性后代成熟度不一致等缺点,提供了一种新的稻瘟病菌有性世代培养的方法——分生孢子涂布法,与现有技术相比,分生孢子涂布法可以在短时间内获得大量的稻瘟病菌有性世代,子囊壳和子囊孢子形成速度快,成熟度一致,得到的子囊壳和子囊孢子能够用于菌株有性生殖能力的量化比较、有性结构观察、核酸提取和基因表达定量分析。

    摘要: A bacterial spore comprising a modified prkC protein, wherein the extracellular domain of the modified prkC protein binds an agent which is not bound by the extracellular domain of the wild- type prkC protein, and wherein the agent is a germinant that stimulates germination of the bacterial spore, or a bacterial spore comprising a modified gerA protein, wherein the gerA protein has been modified such that the spore undergoes germination in the presence of a germinant which does not stimulate germination of a bacterial spore comprising wild- type gerA protein.

    摘要: A lanthanide is combined with a medium to be tested for endospores. The dipicolinic acid released from the endospores binds the lanthanides, which have distinctive emission (i.e., luminescence) spectra, and are detected using photoluminescence. The concentration of spores is determined by preparing a calibration curve that relates emission intensities to spore concentration for test samples with known spore concentrations. A lanthanide complex is used as the analysis reagent, and is comprised of lanthanide ions bound to multidentate ligands that increase the dipicolinic acid binding constant through a cooperative binding effect with respect to lanthanide chloride. The resulting combined effect of increasing the binding constant and eliminating coordinated water and equilibria increase the sensitivity of the endospore assay by an estimated three to four orders of magnitude over prior art of endospore detection based on lanthanide luminescence.

    摘要: The subject invention provides novel and advantageous methods for growing bacteria. The methods of the subject invention are particularly advantageous for growing parasitic bacteria, in vitro , without the presence of host tissue. In one embodiment of the subject invention, Pasteuria spores, such as those that infect the rootknot nematode Meloidogyne arenaria or other host nematodes, are grown in vitro . The process of the subject invention is highly advantageous because Pasteuria can be grown in the absence of nematode tissue.
