Phylogenetic and morphological characteristics of Uromycladium falcatariae, the fungal pathogen that causes gall rust epidemics of Falcataria moluccana in Indonesia

Abstract

Falcataria moluccana (Miq.) Barneby & J.W. Grimes (syn. Paraserianthes falcataria [L.] I.C. Nielsen), locally known as 'sengon', belongs to the family of Fabaceae. The tree is one of the most important forest commodities in Indonesia with wood production being the third-highest after acacias and eucalyptus (Badan Pusat Statistik, 2020). Although the cultivation area is widespread in Java,

Isolation and identification of fungi associated with Falcataria moluccana gall-rust in Kediri, East Java, Indonesia

“…The status of gall rust disease incidence and severity in sengon plants were widespread and very severe, of which could reach 100% (Darwiati and Anggraeni 2018;Firdaus et al 2019;Rahayu et al 2020;Syarifuddin et al 2021). A molecular study identified the gall rust pathogen in sengon and changed the name from Uromycladium tepperianum to U. falcatariae (Doungsa-ard et al 2015;Doungsa-ard et al 2018;Lelana et al 2022). Uromycladium falcatariae is an obligate parasite that can grow and multiply if it remains in contact with its host plant.…”
