BACKGROUND AND AIMS The family Balsaminaceae is essentially herbaceous, except for some woodier species that can be described as 'woody' herbs or small shrubs. The family is nested within the so-called balsaminoid clade of Ericales, including the exclusively woody families Tetrameristaceae and Marcgraviaceae, which is sister to the remaining families of the predominantly woody order. A molecula...

Abstract Passionfruit ( Passiflora edulis ) is widely cultivated in tropical and subtropical regions around the world. Several viruses of genus Potyvirus pose serious threat to passion fruit production. The origin, dispersal evolution these potyviruses, however, are poorly understood. Here, we investigated genetic structure telosma mosaic virus (TelMV), a potyvirus that infects passionfruit Eas...

The prevalence of woody species in oceanic islands has attracted the attention of evolutionary biologists for more than a century. We used a phylogeny based on sequences of the internal-transcribed spacer region of nuclear ribosomal DNA to trace the evolution of woodiness in Pericallis (Asteraceae: Senecioneae), a genus endemic to the Macaronesian archipelagos of the Azores, Madeira, and Canari...

Summa Phytopathol., Botucatu, v. 40, n. 2, p. 134-140, 2014 The purple passionfruit plant, Passiflora edulis Sims, ranks second in fruit exportation in Colombia, and its main destination is the European market. However, its production is affected by several diseases, including fusariosis. This paper presents the histopathological features of different tissues affected by the pathogens Fusarium ...
