Turkish Journal of Botany
Metallothioneins are low-molecular-weight, cysteine-rich proteins able to bind a variety of heavy metal ions. They are involved in the maintenance of micronutrient homeostasis and detoxification of nonessential heavy metals. Plant metallothioneins are classified into four main types based on the number and arrangement of cysteine residues. Here we report on the isolation of novel complementary and genomic DNA from a model for a short-day plant, Ipomoea nil (Japanese morning glory), that encodes 66- or 76-amino acid residue proteins. In silico and phylogenetic analysis of putative amino acid sequences confirmed that these 66- and 76-amino acid residue proteins belong, respectively, to …

Advances To The Taxonomic Knowledge Of Plantago Subulata(Plantago Sect. Maritima, Plantaginaceae), Gustavo Hassemer
Turkish Journal of Botany
Plantago sect. Maritima is a group of Mediterranean narrow-leaved plantains whose taxonomy and nomenclature are particularly complex and still unresolved. This work has the objective of advancing the taxonomic knowledge of this section by revising and presenting novelties for the synonymy of P. subulata, including the lectotypification of four names with recent usage (since 1985) within this group: P. sarda, P. subulata var. atlantis, P. subulata var. granatensis, and P. subulata var. insularis. Furthermore, two synonymizations are newly proposed, and the situation of two Plantago species names published by Nyman in 1881 in his Conspectus Floræ Europææ is clarified.
