枯草芽孢菌株TL2在茶树体内的内生定殖

Colonization of Bacillus subtilis Strain TL2 in Tea Plant

枯草芽孢菌株TL2接种茶树后,可以从茶树不同组织分离到细菌,其细菌种群数量随着时间逐渐减少,其细菌多样性系数也随着时间有所降低。其菌体主要分布在根部厚壁组织的细胞间隙,茎部厚角组织的细胞间隙、维管束等组织的细胞间隙、叶片的气孔器附近、上下表皮细胞间隙、厚角组织细胞间隙以及内皮层组织细胞间隙等。

Bacillus subtilis Strain TL2 was proved to be able to colonize in different tissues inside the tea plant, and the community quality and diversity index of the endophytic bacteria were both decreased in tea plant with the time after inoculated. The bacteri of strain TL2 were found to be mainly distributed in the intercellular space of sclerenchyma in the root, the intercellular space of collenchyma and vascular bundle in the stem, the stomatal apparatus, the intercellular space of epidermal cell, collenchyma and endodermis in the leaf.
