Does climate influence genome size diversity? A study of genome size-environment associations across the Madagascar grass flora

Joseph Morton
Repetitive DNA accumulation and whole genome duplication are common across angiosperm lineages, resulting in some of the largest ever-recorded genomes, yet the majority of angiosperm species have small genomes. This suggests selection may be acting to reduce genome size (GS), and there is growing evidence of environmental factors influencing GS diversity. This paper examines this relationship using a dataset of ecologically diverse Malagasy Poaceae across wide environmental gradients. Flow cytometry was used to estimate 1C-values...

Novel insight into genome size and succulent trait evolution in Aloe (Asphodelaceae)

Kelda Elliott
Through the evaluation of genomic, anatomical, and physiological characters against the most taxa rich phylogenetic hypothesis of the genus Aloe, this research elucidated succulent trait evolution and relationships governing the ‘succulence syndrome’ within this iconic group. Genome size estimates for 110 species produced 2.7-fold 1C variation and range of 13.49-36.42 (pg) and 1.7-fold 1Cx variation and range of 13.49-22.52 (pg), which demonstrates, whole genome duplication is responsible for the majority of genome size variation in...

Can a change in taxonomy help protect species?

Paloma Moore
The genus Pterocarpus contains some of the world’s most heavily traded rosewood species. Presently, three Asian and two African Pterocarpus species are listed as threatened on The IUCN Red List of Threatened Species. Pterocarpus rohrii Vahl is a highly variable species, distributed throughout Central and South America. A recent taxonomic revision of the P. rohrii complex resulted in the reclassification of 588 herbarium records, previously identified as P. rohrii but now recognised to represent 10...

Explaining barkcloth properties through plant anatomy

Roberto Saad
Barkcloth, a material derived from the beaten inner bark of plants, is an ancient textile of widespread origins, recorded in Africa, South America, Europe, Asia, and Oceania, especially the Polynesian Islands. An antiquated craft, the practice of making barkcloth is kept alive by the cultural and spiritual significance it retains in some places, as well as a small commercial demand for it. All barkcloths are manufactured from the bast fibres of a plant’s stem. Historically,...

Revision of Chassalia (Rubiaceae) in Borneo

Tianyi Yu
The genus Chassalia in Borneo is revised based on a morphological survey of herbarium specimens using classical taxonomic methods. The tribal placement and probable paraphyly of Chassaliaas currently delimited is reviewed. Previously four described species of Chassalia were known from Borneo with only one endemic species Chassalia psychotrioides . 12 new species are described in this study, all of them endemic to Borneo. A key is given to the 16 species of the genus now...
