Embodiment 1

[0031] The identification method of embodiment 1.TCK teliospore and TFL teliospore

[0032] 1. Dyeing

[0033] Take one grain of T. dwarf Tilletia galls and one grain of T. glabras galls, put them into small centrifuge tubes respectively, soak in water for 30 minutes, remove the seed coat with tweezers, and centrifuge to remove the supernatant. The samples to be tested were stained with 20 μg / ml WGA-AF488 dye for 60 min, then washed with 1×PBS (pH 7.4) for 3 to 5 times, and stored in 1×PBS for observation. All operations were carried out at room temperature, and the stained samples should be kept away from light.

[0034] 2. Microscopic observation

[0035] Put the teliospores of T. tritici dwarfis and T. glabris after dyeing and washing on concave glass slides respectively, cover them with coverslips and place them under a laser confocal microscope (Leica TCS SP5CLSM) for scanning observation. Select the xyz scanning mode, select the excitation light with an excitation wav...

Abstract

The present invention relates to the field of cell biology technology, and specifically relates to a method for identifying teliospores of wheat dwarf smut and teliospores of wheat light smut. It includes the following steps: stain the samples to be tested that are suspected to be teliospores of P. triticifolia or teliospores of P. triticifolia in WGA‑AF488 dye, then rinse with PBS, and then scan under a confocal laser microscope. Observe; if the ridges and cell walls are both dyed green, the sample to be tested is teliospores of P. tritici; if only the cell wall is dyed green, the sample to be tested is teliospores of P. tritici. The staining results of this method are clear and can quickly and accurately distinguish TCK teliospores and TFL teliospores.

Description

technical field [0001] The invention relates to the technical field of cell biology, in particular to a method for distinguishing the teliospores of Tilletia dwarfis and the teliospores of Tilletia glabris. Background technique [0002] Tilletia controversa Kühn (TCK) caused by Tilletia controversa Kühn (TCK) is an important quarantine ear disease of wheat (Hoffmann, 1982), and it is a serious and highly contagious disease. , Difficult-to-control diseases are also one of the important objects for the study of invasive alien organisms in my country. Common Bunt ofwheat is a devastating and global wheat smut caused by Tilletia foetida (Walle.) Lindr., TFL. It was classified as a quarantine object (Li Jianqiang et al., 2003). Due to the difference in the infection mode and the physiology of the pathogenic bacteria, especially the fundamental difference in the teliospore germination and infection environment, it was only in the 1930s that the wheat dwarf smut was distinguished ...
