Argentophilic structures of the miracidia and cercariae of Philophthalmus distomatosa n. comb. from Israel.

The morphology and patterns of distribution of the argentophilic structures of miracidia and cercariae of Philophthalmus distomatosa n. comb. are described.

Argentophilic structures of miracidia and cercariae of Philophthalmus lucipetus (Philophthalmidae: Trematoda) from Israel.

Argentophilic structures of Philophthalmus lucipetus miracidia and cercariae from Israel are described. Eighty-four of 87 miracidia examined displayed an epidermal plate arrangement of 6:8:4:2 = 20, similar to other Philophthalmus species. Twenty papilla-like structures are arranged on the terebratorium in 3 groups, along 1 axis.

[The transfer of genes for Brown Rust resistance from Aegilops umbellulata Eig. to wheat (Triticum aestivum L.) genome].

The potential of a genome-substituted form Avrolata (AABBUU) as a genetic system in genomic and chromosome manipulations for gene transfer from the wild species Aegilops umbellulata Eig. (UU) to cultivated wheat was studied. It was shown that plants combining resistance to leaf brown rust with high productivity may be produced from this form by classical hybridization procedures.
