Most kelps (order Laminariales) exhibit distinct temporal patterns in zoospore production, gametogenesis and gametophyte reproduction. Natural fluctuations in ambient environmental conditions influence the intrinsic characteristics of gametes, which define their ability to tolerate varied conditions. The aim of this work was to document seasonal patterns in reproduction and gametophyte growth a...

A parasitological survey in the Bay of Fundy, Canada, resulted in the recovery of mature specimens from 5 species of phyllobothriid tapeworms (Cestoda: Tetraphyllidea) from 4 rajid skates: Echeneibothrium canadensis and E. dubium abyssorum specimens from Amblyraja radiata; E. vernetae and Pseudanthobothrium n.sp. from Leucoraja erinacea and L. ocellata; and P. hanseni from A. radiata and Malaco...

The enzyme hydroxycinnamoyl-CoA:shikimate hydroxycinnamoyltransferase (HCT) is involved in the production of methoxylated monolignols that are precursors to guaiacyl and syringyl lignin in angiosperm species. We identified and cloned a putative HCT gene from Pinus radiata, a coniferous gymnosperm that does not produce syringyl lignin. This gene was up-regulated during tracheary element (TE) for...

Our studies confirmed the susceptibility of Macaca radiata (bonnet macaques) to Kyasanur Forest disease (KFD) and enabled us to demonstrate KFD virus-specific gastrointestinal and lymphoid lesions. Significant histopathological changes occurred in the small and large intestine, spleen and lymph nodes; and viral antigens were found in these same organs by immunohistochemistry. Viral antigen-posi...

Among the legume family, mungbean (Vigna radiata) has become one of the important crops in Asia, showing a steady increase in global production. It provides a good source of protein and contains most notably folate and iron. Beyond the nutritional value of mungbean, certain features make it a well-suited model organism among legume plants because of its small genome size, short life-cycle, self...

Resection of insulo-opercular gliomas carries the risk of postoperative hemiparesis caused by ischemia of the corona radiata resulting from injury to the long insular arteries. However, intraoperative identification of these perforating arteries is challenging. We attempted intra-operative motor evoked potential (MEP) monitoring under temporary occlusion of the suspected long insular artery ari...

Seed production was studied in cones from 18 clones of radiata pine (Pinus radiata D. Don) replicated within and between four contrasting sites. At one site which was phosphate-deficient, number of full seeds per cone, along with cone volume #nd mean seed weight, was about one-third less than elsewhere. Empty seeds, although never completely absent, were prevalent only in occasional cones. Such...

A brief study to analyze oxidative stress and antioxidant response of cadmium stress was carried out. The plant chosen Vigna radiata (var. SML-668) was hydroponically grown in 0, 50μM, 100μM and 150μM, cadmium chloride. The roots were taken from hydroponic culture at 6 days of growth for various enzymatic and metabolic estimations. Among the antioxidant enzymes, root catalase and ascorbate pero...

Diameter at breast height (DBH), wood density (DEN) and predicted modulus of elasticity (PME) are considered as 'key traits' (KT) in the improvement in radiata pine breeding programmes in New Zealand. Any other traits which are also of interest to radiata pine breeders and forest growers are called 'non-key traits' (NKTs). External resin bleeding (ERB), internal checking (IC), number of heartwo...
