An outstanding flagship species in the plant kingdom is the Titan arum (Amorphophallus titanum), which produces a fountain-like bloom up to 3 m high. The unique appearance of three simultaneous inflorescences in May 2006 was a chance to analyse the flowering behaviour and thermogenesis of this giant. For the first time, the heating of the central column (spadix) could be documented using a high...

We describe the cypridoidean ostracod Heterocypris spadix sp. nov. from brackish water on Okinawa Island, Japan. The species closely resembles salina (Brady, 1868) but differs in that (1) marginal infolds valves are less developed, (2) tubercles anterior margin of right valve completely covered by selvage and invisible inner view, (3) calcified lamella ventral left is scarcely evident as margin...

Pseudoxanthomonas spadix BD-a59, able to metabolize all six BTEX (benzene, toluene, ethylbenzene, and o-, m-, and p-xylene) compounds, was isolated from gasoline-contaminated sediment. Here, we report the complete 3.45-Mb genome sequence and annotation of strain BD-a59. These advance the understanding of strain BD-a59's genomic properties and pollutant metabolic versatility.

1. Mitochondria isolated from the thermogenic spadices of Arum maculatum and Sauromatum guttatum plants oxidized external NADH, succinate, citrate, malate, 2-oxoglutarate and pyruvate without the need to add exogenous cofactors. 2. Oxidation of substrates was virtually all via the alternative oxidase, the cytochrome pathway constituting only 10-20% of the total activity, depending on the stage ...

in the present study, randomly amplified polymorphic dna (rapd) markers were used to analyze the genetic diversity in 20 varieties of philodendron. the polymerase chain reaction was performed with 60 rapd primers, out of which 21 primers showed clear amplification as well as more polymorphism. in total, 354 scorable rapd loci with 348 polymorphic bands (98%) were observed. percentages of polymo...

The pollination ecology of Symplocarpus foetidus (L.) W. Salisbury was studied in a seasonally forested flooded bog Québec (Canada) 2008 and 2009. protogynous anthesis duration ranged from 15 to 20 days with, chronologically, female phase about 5 days, bisexual 2 male 9 days. spadix temperature differences with ambient air were higher during the (mean: 13.6°C) than phases 4.5°C). inside floral ...
