5'-Methylthioadenosine (MTA) nucleosidase (MTN) plays a key role in the methionine (Met) recycling pathway of plants. Here, we report the isolation of the 1158 bp full-length, cDNA sequence encoding tetraploid black locust (Robinia pseudoacacia L.) MTN (TrbMTN), which contains an open reading frame of 810 bp that encodes a 269 amino acid protein. The amino acid sequence of TrbMTN has more than ...

S-Adenosylmethionine synthetase (SAMS) catalyzes the synthesis of S-adenosylmethionine (SAM), a precursor for ethylene and polyamine biosynthesis. Here, we report the isolation of the 1498 bp full-length cDNA sequence encoding tetraploid black locust (Robinia pseudoacacia L.) SAMS (TrbSAMS), which contains an open reading frame of 1179 bp encoding 392 amino acids. The amino acid sequence of Trb...

On the UK Continental Shelf, up to 80,000 tonnes wet weight of oily drill cuttings are produced annually. These are heterogeneous wastes generated from the petroleum drilling industry, composed of significant percentages of hydrocarbons, heavy metals and chlorides. Since 1992, the discharge of drill cuttings containing more than 1% oil-on-cuttings has been prohibited. Moreover, the extensive in...

Influences of irrigation frequency on the growth and flowering of chrysanthemum grown under restricted root volume were tested. Chrysanthemum cuttings (Chrysanthemum morifolium "Reagan White") were grown in seedling tray which contained coconut peat in volumes of 73 and 140 cm(3). Plants were irrigated with drip irrigation at irrigation frequencies of 4 (266 mL), 6 (400 mL), and 8 (533 mL) time...

Ceratocystis wilt on eucalyptus, caused by Ceratocystis fimbriata, was first recognized in 1997 in the state of Bahia, Brazil, but is now known in five other states and in four other countries. C. fimbriata is a native, soilborne pathogen in some parts of Brazil but we hypothesized that genotypes of the pathogen have been moved among plantations in rooted cuttings collected from diseased trees ...

Androgaphis lineate Nees., an important tribal medicinal plant of the Shevaroy Hill was noted to be restricted in its distribution due to biotic pressure. The species was successfully propagated by stem cuttings in its habitat. The percentage establishment of stem cuttings was 67.

this research was carried out to determine the chilling and heat requirements of grapevine cultivars(rotabi, siah shiraz and yaguti) and carbohydrate and hormones changes in chilled cuttings. uniform cuttings of above mentioned cultivars were harvested when leaves were abscised in autumn, and then transferred to refrigerator (2˚c). cuttingswere subjected to 0 (unchilled control), 100, 200, 300,...

Given n lines in the plane, a (1/r)-cutting is a subdivision of the plane into cells such that each cell intersects at most n/r lines. Cuttings are fundamental to the design of geometric divide-and-conquer algorithms and have numerous applications. Early suboptimal constructions of cuttings were given implicitly in the works by Megiddo and by Dyer in the 80s; simple randomized constructions wer...
