OBJECTIVE Choroidal neovascularization (CNV) is a complication of multiple eye diseases, including age-related macular degeneration, that usually results in irreversible vision loss. It is characterized by proliferation and growth of choroidal blood vessels through Bruch's membrane into the

In the ovaries of the oviparous morph of the aphid, Megoura viciae, resting oocytes are located in the basal region of each germarium. During previtellogenic egg development, electron-dense spheres appear in the ooplasm. During vitellogenesis a brush border develops at the oolemma, and numerous

cDNA clones encoding cysteine proteinases from cotyledons of germinated seeds of Vicia sativa L. have been obtained by means of PCR. Degenerate oligonucleotide primers were designed according to conserved amino acid regions of known cysteine proteinases. The deduced amino acid sequences of the cDNA

Legumes are amongst the most promising crops to satisfy the increasing demand for protein-rich food and feed. Today, however, their cultivation in Europe is low, while European agriculture faces a deficit of protein-rich feed, of which the largest part is met by imported soybean. It has been

A homologue of Sinorhizobium meliloti bacA was isolated from Mesorhizobium huakuii 7653R, which is capable of fixing atmospheric nitrogen in symbiotic association with leguminous Astragalus sinicus (Chinese milk vetch). Inactivation of the bacA gene abolished the ability of M. huakuii 7653R to
