Abstract
Penicillium brasilianum Bat., P. cluniae Quintan., and P. echinulonalgiovense S. Abe ex Houbraken & R.N. Barbosa are reported for the first time as endophytes from the leaves of an endemic bromeliad in the Caatinga dry forest in Brazil. For species determination, phenotypic features were analysed along with the sequencing of the β-tubulin and calmodulin genes. Penicillium Link isolates obtained in this study showed the typical morphology of species in the Lanata-Divaricata section. These results contributed to increase the knowledge of fungal diversity in dry environments in the word.
Highlights
Penicillium species are found on a wide variety of substrates and are the most well distributed fungi in the world (Visagie et al 2014)
The collections were authorized by the Ministério do Meio Ambiente (MMA)/ Instituto Chico Mendes de Conservação da Biodiversidade (ICMBio); permission number: 48641-1/authentication code 17827693 issued on April 10, 2015
For the analysis of the macroscopic morphological characteristics, 1 μL of the spore suspension was inoculated at three points in each Petri plate containing one of the following culture media: Czapek yeast extract agar (CYA), malt extract agar (MEA), oatmeal agar (OA), dichloran glycerol agar (DG18), Czapek sucrose extract agar (CYAS), yeast extract sucrose agar (YES), and creatine sucrose agar (CREA)
Summary
Penicillium species are found on a wide variety of substrates and are the most well distributed fungi in the world (Visagie et al 2014) These fungi are of great importance in the fields of medicine, agriculture, production of industrially important enzymes, decomposition of organic matter such as food, and indoor environments (Houbraken et al 2014). Till & J.A. Siqueira is an endemic plant in Brazil, native to the Caatinga region, and is currently at critical risk of extinction (Forzza et al 2015).
