百合组织中细胞内生菌的分布与传播

THE DISTRIBUTION AND PROPAGATION OF ENDOPHYTIC BACTERIA WITHIN THE CELLS OF LILY TISSUE

  • 摘要: 在百合鳞茎、根、地上茎、叶和花蕾组织细胞中观察到细菌的分布。但各组织器官之间、细胞内所含细菌的数量差异很大。鳞茎组织细胞内含菌量最多。同一鳞茎,外围鳞片细胞内含菌量高于内侧。生长锥顶端分生组织细胞内未观察到细菌的分布。在生长锥中部有少量细菌出现,而基部则含有较多的细菌。百合鳞茎最外一层鳞片的外表皮中,细胞内有许多呈树丛状分布的类似侵染线的管状结构,它们与细胞壁发生联系,推测这些细菌可能是外源的。细菌随着植株的生长发育,由已成熟的含菌细胞向幼嫩的不含菌细胞中传播。细菌在细胞之间的传播可能是通过细胞壁上纹孔间的胞间连丝孔道。

     

    Abstract: Distribution of endophytic bacteria was observed within the tissue and cells of bulb, roots, stem, leaves and floral bud of lily, but the number of bacteria is different. The number of bacteria is highest within the bulb cells of lily. It my-be relating to the content of nutriment. The number of the bacteria within the cells of outside scale is higher than that inside. In the bulb of lily the bacteria within the meristematic cells of growing tip are less or without, but there are more in the mature cells of base. Within the epidermis cells of outside scale, numerous tube-lick structures which appear to arbuscules as infection line is shown in the most outside layer of lily bulb. These structures associated with cell wall, it is possible for an infection passage of the bacteria from soil. In our inference, the bacteria within the cells is no endophyte, because the propagation of the bacteria can distribute from mature cells containing bacteria into the meristematic cells following the development. The propagational way of the bacteria passed through is a pore of plasmodesma between pit-pair on the wall. After the microtubele of the plasmodesma is damaged, the bacteria goes from one cell into another cell following cytoplasm.
