چکیده مقاله :
This study delves into the impact of seasonal variations on the diversity of endophytic fungi inhabiting the
foliage of Grevillea robusta trees along highways in Hawassa, Ethiopia. With 765 fungal isolates categorized
into 73 distinct morphotaxa, 90.41% were identified across eight known genera, leaving 9.58% unidentified.
Notably, Phoma and Pestalotiopsis emerged as the most diverse genera, presenting 13 and 11 morphotaxa
respectively, while Alternaria and Xylaria showed lower diversity with 3 and 2 morphotaxa each. The research
unveiled heightened fungal counts and diversity in trees situated in more polluted environments, leaves
sampled during dry seasons, those exhibiting signs of disease, lower leaf sections, and midrib samples. These
findings underscore the rich assortment of endophytic fungi associated with Grevillea robusta leaves within
roadside plantations in Hawassa, emphasizing the need for further exploration of this fungal community’s
dynamics. Understanding the pivotal role of these endophytic fungi in tree health, ecosystem resilience, and
potential applications in agriculture, forestry, and biotechnology remains imperative.
