A gene encoding a sulphur-rich, sunflower seed albumin (23% cysteine plus methionine) was modified to contain the promoter for the 35S RNA of cauliflower mosaic virus, in order to obtain leaf expression in transgenic plants. In addition, a sequence encoding an endoplasmic reticulum-retention signal

Ecological risk assessment is an important step in the production and commercialisation of transgenic plants. To date, however, most risk assessment studies have been performed on crop plants, and few have considered the ecological consequences associated with genetic modification of pasture

In order to improve the quality of pasture protein for ruminant animal nutrition, we are introducing genes encoding rumen-protected proteins, rich in essential amino acids, into white clover (Trifolium repens L.). We have introduced a chimaeric gene transcribed from the 35S CaMV promoter, and

With the aim of increasing the rumen-protected level of the sulphur amino acids cysteine and methionine in Trifolium repens, we introduced the coding sequence of the sunflower seed albumin (SSA) into T. repens by Agrobacterium tumefaciens-mediated transformation. The SSA gene was modified such that

A transgenic line of subterranean clover (Trifolium subterraneum) containing a gene for a sulphur-rich sunflower seed albumin (ssa gene) and a gene conferring tolerance to the herbicide phosphinothricin (bar gene) was previously shown to stably express these genes as far as the T3 generation. In

BACKGROUND The cycling of peptide and protein-bound amino acids (AAs) is important for studying the rate limiting steps in soil N turnover. A strong tool is stable C and N isotopes used in combination with compound-specific isotope analysis (CSIA), where a prerequisite for analysis is appropriate

The protein precipitation (PP) of bovine serum albumin (BSA), lysozyme (LYS), and alfalfa leaf protein (ALF) by four procyanidin-rich condensed tannin (CT) samples in both 2-[N-morpholino]ethanesulfonic acid (MES) and a modified Goering-Van Soest (GVS) buffer is described. Purified CT samples

The precipitation of bovine serum albumin (BSA), lysozyme (LYS), and alfalfa leaf protein (ALF) by two large- and two medium-sized condensed tannin (CT) fractions of similar flavan-3-ol subunit composition is described. CT fractions isolated from white clover flowers and big trefoil leaves exhibited

Twelve lambs, paired on the basis of live weight, were cannulated in the abomasum, in the proximal jejunum approximately 4 m distal to the pylorus and in the terminal ileum. Six were infected with 3000 Trichostrongylus colubriformis and 3000 Ostertagia circumcincta larvae each day for 18 weeks and

OBJECTIVE To measure the effects of AR37, AR1 and Wild-type endophytes in perennial ryegrass on cow health and milk production. METHODS Four indoor and six grazing experiments were used to evaluate a perennial ryegrass cultivar containing either novel (AR37, AR1) or Wild-type (HE or Standard)
