Nacrein is the first identified and widely investigated molluscan matrix protein and is considered to play an important role in the shell formation of the pearl oyster, Pinctada fucata. Here, we investigate the effect of the NF-κB signalling pathway on Nacrein gene expression in P. fucata to elucidate the mechanisms involved in shell formation. Inhibition of NF-κB signalling decreased Nacrein p...

The objective of this work was to screen the EU-regulated lipophilic and cyclic imine toxins in four bivalve species (Atrina vexillum, Pinctada imbricata, Anadara antiquata, Saccostrea Cucculata) from Mozambican coast Indian Ocean. Toxins were extracted analyzed according EU reference method for determination shellfish via LC–MS/MS, but no regulated found species. However, pinnatoxins (PnTX G, ...

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...
