Alyssum contemptum Schtt.et Kotschy

Cellular compartmentation of nickel in the hyperaccumulators Alyssum lesbiacum, Alyssum bertolonii and Thlaspi goesingense.

Nickel uptake and cellular compartmentation were investigated in three Ni hyperaccumulators: Alyssum bertolonii (Desv), Alyssum lesbiacum (Candargy) and Thlaspi goesingense (Hálácsy). The three species showed similar hyperaccumulation of Ni, but T. goesingense was less tolerant to Ni than the two Alyssum species. An addition of 500 mg Ni kg(-1) to a nutrient-rich growth medium significantly inc...

Alyssum desertorum Stapf ( Brassicaceae ) , new for the Italian fl ora

The occurrence of Alyssum desertorum, a species belonging to A. sect. Alyssum, is reported for the fi rst time in Italy. It was found in Abruzzo (central Italy) in the territory of National Park of Gran Sasso and Laga mountains and surrounding areas. Morphological similarities with the other taxa recorded in Italy belonging to A. sect. Alyssum are briefl y discussed. Information about the typif...

Growth and Metal Accumulation of an Alyssum murale Nickel Hyperaccumulator Ecotype Co-cropped with Alyssum montanum and Perennial Ryegrass in Serpentine Soil

The genus Alyssum (Brassicaceae) contains Ni hyperaccumulators (50), many of which can achieve 30 g kg(-1) Ni in dry leaf. Some Alyssum hyperaccumulators are viable candidates for commercial Ni phytoremediation and phytomining technologies. It is not known whether these species secrete organic and/or amino acids into the rhizosphere to solubilize Ni, or can make use of such acids within the soi...
