Abstract

As a fungal endophyte involved in the host, the influences of Epichloë yangzii to morphological properties of the host Roegneria kamoji (Ohwi) Kent et Chen are not clear. To evaluate the influences of stroma development on host morphological properties, R. kamoji plants harboring sexual endophyte E. yangzii Li et Wang were collected from Jiangpu in Nanjing, and differences between stromatal plants and non-stromatal plants on tillering and heading of the plants, thickness and length of the culms, numbers, morphology and senescence of the leaves were investigated. In the results, stroma development of E. yangzii promoted the growth of the flag leaf, delayed senescence of plant leaves on both stromatal and non-stromatal culms of the plants, but decreased tiller number of the plant and inhibited the inflorescence emergence of the culm. Overgrowth of fungal hyphae blocked the emergence path, resulted failure of the inflorescence emergence of non-heading culms. Decrease of tiller number indicated that influences of stroma development occur before plant vernalization of the hosts although stroma developed at the early stage of emergence of flag leaf sheath or inflorescence. Delay of leaf senescence on the hole plants indicates signal(s) caused by stromatal development can also transfer to the non-stromatal tillers of the same plant. Mechanisms and significances of these influences mediated by stroma development should be investigated in future.
