The Botryosphaeriaceae includes several species that are serious canker and leaf pathogens of Proteaceae. In the present study, sequence data for the ITS nrDNA region were used in conjunction with morphological observations to resolve the taxonomy of species of Botryosphaeriaceae associated with Proteaceae. Neofusicoccum luteum was confirmed from Buckinghamia and Banksia in Australia, and on Pr...

Defense elicitors are products that activate acquired defense responses in plants, thus rendering the plants less susceptible to attack by a broad range of pests. We demonstrated previously under laboratory conditions that foliar applications of the defense elicitors Actigard (acibenzolar-S-methyl), Employ (harpin protein), or ODC (chitosan) to potted pear trees (Pyrus communis L.) each caused ...

The diversifi ed genus Passifl ora is well distributed all over Brazil, and many species have been long used as medicinal plants, mainly against anxiety disturbances. This effect has been attributed to its rich fl avonoid composition. Flavonoids’ main class, fl avonoid glycosides, has presented central action, particularly as sedativehypnotic, anxiolytic and analgesic. The objective of the pres...

While gene duplication is a major source of evolutionary novelty, the importance of this process in reproductive protein evolution has not been widely investigated. Here, we report the first known case of gene duplication of abalone sperm lysin in an allopatric subspecies found in the Eastern Atlantic, Haliotis tuberculata coccinea. Mass spectrometry identified both copies of the lysin protein ...

Volatile compounds from seven Salvia species and one interspecific hybrid growing at the Dallas Arboretum and Botanical Garden, Texas, US. Salvia coccinea, S. farinacea, S. greggii, S. leucantha, S. longispicata x farinacea, S. madrensis, S. roemeriana and S. splendens were investigated for their chemical compositions using a microdistillation technique. Volatiles were analyzed by gas chromatog...

The study examine the antioxidant and antimicrobial potential of the ethanolic and aqueous leaf extracts of ten selected Indian medicinal plants namely, Psidium guajava, Mangifera indica, Polyalthia longifolia, Allium cepa, Phyllanthus amarus, Thespesia populnea, Ricinus communis, Physalis angulata, Ixora coccinea, and Vinca rosea using 2, 2-Diphenyl-1-picrylhydrazyl (DPPH) scavenging assay, to...
