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
Pigeon pea is an important pulse crop grown in diversified cropping systems in India. In the rainy season of August 2011 and September 2012, pigeon pea cv. LRG 30 plants with leaf necrosis having wrinkled margin on one side were observed in Kadiri mandal of the Anantapuram district of Andhra Pradesh
OBJECTIVE
Trifolium repens (white clover) is a valuable component of pastures due to its ability to fix nitrogen. Productivity of T. repens is sometimes threatened by insect pests, and it has been suggested that phenylpropanoid-derived isoflavonoids such as formononetin can protect white clover from
Rx-mediated resistance was analyzed in Rx-expressing transgenic Nicotiana plants. The infection outcome of nine Potato virus X isolates mutated at amino acid positions 121 and 127 of the coat protein (CP) confirmed the key role of these amino acids but provided a more complex picture than previously
Cymbidium mosaic virus (CyMV) is the most prevalent virus infecting orchids. Here, we report the isolation of partial cDNA clones encoding the genomic RNA of CyMV. Like most of the polyadenylated monopartite positive-strand RNA viruses, the open reading frame (ORF) coding for the viral coat protein
Fragaria (strawberry) and Rubus species (blackberry, wild blackberry, red raspberry and black raspberry) were thought to be infected with distinct isolates of Tobacco streak virus (TSV). Employing serology and nucleic acid hybridization it has been shown that these isolates form a cluster distinct
Isolated tobacco streak virus strain mild (TSV-M) top nucleoprotein component (TV) was crystallized by vapor diffusion with polyethylene glycol (PEG) and methyl pentanediol. The morphology of the crystal suggested a hexagonal space group, however, the crystals were disordered as analyzed by X-ray
Rubus ellipticus is a perennial shrub occurring in natural vegetation of the temperate and subtropical Himalayas. For several years, plants of R. ellipticus in and around the Institute of Himalayan Bioresource Technology in Palampur were seen with mild mosaic and chlorotic symptoms on leaves
In vivo and in vitro phosphorylation and intracellular location of rice dwarf phytoreovirus Pns12, which is encoded by one of the twelve dsRNA genome segments, S12, and comprises 312 amino acids, was investigated. When [32P]phosphoric acid was incorporated into RDV-infected leafhopper cultured
Cigarette filters (butts) are currently the most abundant form of anthropogenic litter on the planet, yet we know very little about their environmental impacts on terrestrial ecosystems, including plant germination and primary production. When discarded, filters contain a myriad of chemicals
In May 2001, severe stunting, lateral rot, and brown discoloration of taproots were observed in a field of direct-seed (no-till) pea cv. Columbia southeast of Lewiston, ID. The field had been previously cropped with direct-seeded spring barley. Roots were washed, plated on water agar containing
Kura clover (Trifolium ambiguum M. Bieb.) has been reported to be resistant to several viruses, including Alfalfa mosaic virus (AMV), Bean yellow mosaic virus (BYMV), Clover yellow vein virus (CYVV), Peanut stunt virus, Red clover vein mosaic virus (RCVMV), and White clover mosaic virus (WCMV) (2).
White clover (Trifolium repens L.) is a herbaceous, perennial plant that has become one of the most widely distributed legumes in the world. It is extensively used in grass-legume pastures, but also has the potential to invade agricultural lands and natural ecosystems. White clover is a well-known
Double-stranded cDNA of potato virus X (PVX) genomic RNA has been cloned and sequenced. The sequence [6435 nucleotides excluding the poly(A) tract] revealed five open reading frames (ORFs) which were numbered one to five starting at the 5' terminus of the RNA. They encoded proteins of Mr 165588
