Abstract The objective of this work was to evaluate the effects indolebutyric acid (IBA) concentration, substrate composition and volume, propagule type on adventitious rooting quality Cordia trichotoma plantlets produced by mini-cuttings. Mini-cuttings were evaluated for percentage root number length at 30 60 days cultivation. Plantlets shoot height stem diameter 30, 60, 90, 120 Dickson index,...

Sponge samples were taken by SCUBA diving from sixteen sites on the north coast of South Georgia island, south west Southern Ocean. Fifteen new species are described: Iophon husvikensis sp. nov., Clathria (Clathria) stromnessa sp. nov., Clathria (Axosuberites) rosita sp. nov., Clathria (Microciona) matthewsi sp. nov., Lissodendoryx (Ectyodoryx) collinsi sp. nov., Hymedesmia (Hymedesmia) barnesi...

Our study examines how the mutualism between Atta colombica leaf-cutting ants and their cultivated fungus is influenced by the presence of diverse foliar endophytic fungi (endophytes) at high densities in tropical leaf tissues. We conducted laboratory choice trials in which ant colonies chose between Cordia alliodora seedlings with high (E(high)) or low (E(low)) densities of endophytes. The E(h...

PrTX-I, a noncatalytic and myotoxic Lys49-phospholipase A(2) from Bothrops pirajai venom, was crystallized in the presence of the inhibitor rosmarinic acid (RA). This is the active compound in the methanolic extract of Cordia verbenacea, a plant that is largely used in Brazilian folk medicine. The crystals diffracted X-rays to 1.8 A resolution and the structure was solved by molecular-replaceme...
