Visible absorption spectra are presented for the Azolla caroliniana Willd.-Anabaena azollae Strass. association and the individual partners. Although absorption by the phycobiliproteins of the endophytic cyanobacterium clearly complements the absorption by the fern pigments, their contribution to the absorption spectrum of the association is effectively concealed by the preponderance of the Azo...

AbstrakPenelitian ini bertujuan untuk mengetahui Pengaruh pemberian pakan buatan berbahan tepung azolla (Azolla microphylla) dengan dosis yang berbeda terhadap pertumbuhan dan kelangsungan hidup ikan gurami (Osphronemus gouramy). Pelaksanaan penelitian dilakukan di Balai Benih Ikan (BBI) kota Gorontalo selama 35 hari. Metode menggunakan Rancangan Acak Lengkap (RAL) 4 perlakuan 3 ulangan. Perlak...

 The aquatic fern Azolla, a small-leaf floating plant that lives in symbiosis with a nitrogen fixing cyanobacteria (Anabaena), is an outstanding plant, thanks to its high biomass productivity along with its tremendous rate per unit area for nitrogen-fixation.  The present study investigates the potential growth of Azolla in secondary effluents for removal of COD, phosphorus, and nitrogen. Resul...

Floating ferns of the genus Azolla detach their roots under stress conditions, a unique adaptive response termed rapid root abscission. We found that Azolla pinnata plants exhibited dose-dependent rapid root abscission in response to the polyamines spermidine and spermine after a substantial time lag (>20 min). The duration of the time lag decreased in response to high pH and high temperature w...

Much of science progresses within the tight boundaries of what is often seen as a "black box". Though familiar to funding agencies, researchers and the academic journals they publish in, it is an entity that outsiders rarely get to peek into. Crowdfunding is a novel means that allows the public to participate in, as well as to support and witness advancements in science. Here we describe our re...

Ferns are the only major lineage of vascular plants not represented by a sequenced nuclear genome. This lack of genome sequence information significantly impedes our ability to understand and reconstruct genome evolution not only in ferns, but across all land plants. Azolla and Ceratopteris are ideal and complementary candidates to be the first ferns to have their nuclear genomes sequenced. The...
