Abstract

Abstract:

Five hundred and twenty-nine isolates of fungal endophytes were isolated from the lamina, mid-rib, bark and the xylem of stem of Aegiceras corniculatum, among them 297 isolates in wet and 232 in dry season. The taxa of preponderant fungal endophyte communities differed in the four organs of Aegiceras corniculatum: in lamina are Penicillium and Aureobasidium, in mid-rib are Penicillium and Cladosporium, in bark are the sterile groups, and in xylem of stem are Aureobasidium and Cladosporium. These results indicated that there was some degree of organ specific in distribution of fungal endophytes. The preponderant taxa of endophyte assemblages in organs were different between wet and dry seasons. For example, in lamina, wet season were Penicillium and Aureobasidium, but dry season were sterile groups B and C. It showed that the density and the taxa of the endophyte communities in Aegiceras corniculatum were influenced by the environmental factors such as precipitation, temperature, humidity, and intensity of sunlight.

Key words: Aegiceras corniculatum, fungal endophytes, distribution of communities
