Karyomorphometry on three polyploid species of Arum L. (Araceae, Aroideae) [PDF]
Comparative Cytogenetics, 2014 In this study three polyploid Arum Linnaeus, 1753 species from Southern Italy were chromosomally investigated. Arum italicum Miller, 1768 was found to have 2n = 84 chromosomes and a karyotype composed of numerous asymmetric chromosomes.

Patterns and drivers of heat production in the plant genus Amorphophallus
The Plant Journal, Volume 115, Issue 4, Page 874-894, August 2023., 2023 SUMMARY Thermogenesis – the ability to generate metabolic heat – is much more common in animals than in plants, but it has been documented in several plant families, most prominently the Araceae. Metabolic heat is produced in floral organs during the flowering time (anthesis), with the hypothesised primary functions being to increase scent ...

Target sequence data shed new light on the infrafamilial classification of Araceae
American Journal of Botany, Volume 110, Issue 2, February 2023., 2023 Abstract Premise Recent phylogenetic studies of the Araceae have confirmed the position of the duckweeds nested within the aroids, and the monophyly of a clade containing all the unisexual flowered aroids plus the bisexual‐flowered Calla palustris. The main objective of the present study was to better resolve the deep phylogenetic relationships among ...

Journal of Systematics and Evolution, Volume 61, Issue 1, Page 64-79, January 2023., 2023 A phylogenomic study of Amorphophallus from plastid DNA revealed a new scenario and timeline for the evolution of the main clades, consistent with their morphological characteristics, past climate dynamics, and long‐distance dispersal events across the genus. Abstract Encompassing ca.

Climatic and biogeographical drivers of functional diversity in the flora of the Canary Islands
Global Ecology and Biogeography, Volume 31, Issue 7, Page 1313-1331, July 2022., 2022 Abstract Aim Functional traits can help us to elucidate biogeographical and ecological processes driving assemblage structure. We analysed the functional diversity of plant species of different evolutionary origins across an island archipelago, along environmental gradients and across geological age, to assess functional aspects of island ...

L-Asparaginase Production by Erwinia aroideae [PDF]
Applied Microbiology, 1969 Maximum yields of 1,250 IU (international unit)/g (dry weight of cells) of L-asparaginase were obtained in 8 hr from Erwinia aroideae NRRL B-138. Partial purification and concentration of the extracted L-asparaginase yielded a preparation with an activity of 275 IU/ml.

L-Asparaginase Synthesis by Erwinia aroideae [PDF]
Applied Microbiology, 1972 Maximum L-asparaginase activity was obtained when 1.0% lactose and 1.5% yeast extract were supplied as carbon and nitrogen sources, respectively. Glucose inhibited the enzyme formation. The diauxie phenomenon was observed with Erwinia aroideae NRRL B-138 grown in a medium containing glucose and lactose.

Chloroplast genome evolution in the Dracunculus clade (Aroideae, Araceae)
Genomics, 2021 Chloroplast (cp) genomes are considered important for the study of lineage-specific molecular evolution, population genetics, and phylogenetics. Our aim here was to elucidate the molecular evolution in cp genomes of species in the Dracunculus clade (Aroideae, Araceae).
