Selection of reference genes for expression analysis in the entomophthoralean fungus Pandora neoaphidis 58
Chen,Chun; Xie,Tingna; Ye,Sudan; Jensen,Annette Bruun; Eilenberg,J ørgen.
Abstract The selection of suitable reference genes is crucial for accurate quantification of gene expression and can add to our understanding of host–pathogen interactions. To identify suitable reference genes in Pandora neoaphidis, an obligate aphid pathogenic fungus, the expression of three traditional candidate genes including 18S rRNA(18S), 28S rRNA(28S) and elongation factor 1 alpha-like protein (EF1), were measured by quantitative polymerase chain reaction at different developmental stages (conidia, conidia with germ tubes, short hyphae and elongated hyphae), and under different nutritional conditions. We calculated the expression stability of candidate reference genes using four algorithms including geNorm, NormFinder, BestKeeper and Delta Ct. The...

Colletotrichum nymphaeae var. entomophilum var. nov. a natural enemy of the citrus scale insect, Praelongorthezia praelonga (Hemiptera: Ortheziidae) 63
Wynns,Anja Amtoft; Jensen,Annette Bruun; Eilenberg,Jørgen; Delalibera Júnior,Italo.
ABSTRACT: The citrus scale insect Praelongorthezia praelonga (Douglas), a major pest of citrus and other economically important crops, has only two commonly documented natural enemies: an entomopathogenic strain of the fungus Colletotrichum nymphaeae (Pass.) Aa and several parasitoids. The entomopathogenic strain of C. nymphaeae, formerly recognized under the synonym C. gloeosporioides f. sp. ortheziidae, is under development for commercial application as a biological control agent in citrus in Brazil-the top exporter of citrus globally. The synonomy of C. gloeosporioides f. sp. ortheziidae with C. nymphaeae remains based on limited DNA sequence data and without morphological study. To qualify for future approval as a biological control agent by federal...
