Salvinia molesta
TaxID: 167732
Basic Information
Salvinia molesta
African payal, Kariba Weed
Salvinia molesta is commonly known as giant salvinia, or kariba weed, after it infested a large portion of Lake Kariba between Zimbabwe and Zambia. It is a free-floating aquatic fern, with fronds that are 0.5 C4 centimetres (0.20 C1.6 in) long and broad, with a bristly, waterproof surface caused by the hair-like strands that join at the end to form eggbeater shapes. The fronds are produced in pairs with a third modified root-like frond that hangs in the water. Though native to south-eastern Brazil, it has been accidentally introduced or escaped to countless lakes throughout the United States, including Caddo Lake in Texas, where the invasive species has caused eutrophication to occur. Since 2019, S. molesta has been included in the European Union's List of invasive alien species of Union concern. The species cannot be imported, cultivated, transported, commercialized, planted, or intentionally released into the environment in the European Union.

PRJNA1185439 SRX26700251 SRP544838 general RNAseq Salvinia molesta whole plant Total RNA was extracted from whole plants of a single clonal colony. RNA was depleted of ribosomal RNAs using an Illumina Ribo-Zero Plus rRNA Depletion kit. 150 nt paired end libraries were prepared using an Illumina TruSeq Stranded mRNA kit and sequenced by Novogene (Singapore) on an Illumina HiSeq2500. 110M reads were requested.
