Modifications of Prenyl Side Chains in Natural Product Biosynthesis

open access: yesAngewandte Chemie, Volume 136, Issue 52, December 20, 2024.
This review summarizes the unique modifications of prenyl side chains involved in natural product biosynthesis, including epoxidation, dehydrogenation, oxidation of methyl groups to carboxyl groups, C−C bond cleavage and oxidative cyclization. Abstract In recent years, there has been a growing interest in understanding the enzymatic machinery ...

Phylogenetic analysis of the Monogenea and their relationships with Digenea and Eucestoda inferred from 28S rDNA sequences

open access: yes, 1997
Platyhelminth phylogeny is controversial. Phylogenetic analyses of the partial domain C1 and the full domains D1 and C2 (358 nuclcotides) from the 28S ribosomal RNA gene for 21 species from the Monogenea, Digenea, Cestoda, and, as the outgroup ...

Spermatogenesis in the hermaphroditic Digenea (Trematoda)

open access: yesParasitology, 1965
While some variation of detail may be found in different species of the hermaphroditic Digenea, the process of spermatogenesis conforms to a common plan throughout the group. There is divergence of opinion concerning the interpretation of the structure of the ripe spermatozoon.In the testis of a young animal, primary, secondary and tertiary ...

Oogenesis in the hermaphroditic Digenea (Trematoda)

open access: yesParasitology, 1964
During the present century oogenesis and maturation have been extensively studied in the Digenea. The earlier observations, however, were based on limited methods of histological and cytological techniques and were concerned principally with the general features of the germ-cells and with their chromosomes.
