Effects of water stress cycles on turgor maintenance processes in pear leaves (Pyrus communis).
Effects of water deficits on leaf turgor maintenance processes were analyzed for pear trees (Pyrus communis L. cv. "Barlett") grown in 120-liter containers. Four irrigation treatments were applied: a well-watered control treatment, a spring water stress cycle (Sp), a summer water stress cycle (Su), and a spring plus summer water stress cycle (Sp + Su). For the Sp treatment, water application wa...
متن کاملThe Draft Genome Sequence of European Pear (Pyrus communis L. ‘Bartlett’)
We present a draft assembly of the genome of European pear (Pyrus communis) 'Bartlett'. Our assembly was developed employing second generation sequencing technology (Roche 454), from single-end, 2 kb, and 7 kb insert paired-end reads using Newbler (version 2.7). It contains 142,083 scaffolds greater than 499 bases (maximum scaffold length of 1.2 Mb) and covers a total of 577.3 Mb, representing ...
متن کاملAntinociceptive activity of Ricinus communis L. leaves.
OBJECTIVE To evaluate the antinociceptive activity of the methanol extract of Ricinus communis leaves (MRCL). METHODS Antinociceptive activity was evaluated using acetic acid induced writhing test, formalin induced paw licking and tail immersion method in mice at doses of 100, 125 and 150 mg/kg bw. RESULTS The results indicated that MRCL exhibited considerable antinociceptive activity again...
متن کاملProtein Synthesis and Breakdown during Heat Shock of Cultured Pear (Pyrus communis L.) Cells.
Cultured pear (Pyrus communis L. cv Passe Crassane) cells were subjected to temperatures of 39, 42, and 45[deg]C. Heat-shock protein (hsp) synthesis was greater at 30[deg]C than at temperatures above 40[deg]C and continued for up to 8 h. Both cellular uptake of radiolabeled methionine and total protein synthesis were progressively lower as the temperature was increased. Polysome levels decrease...
متن کاملStudy of factors affecting direct shoot regeneration of pear (Pyrus communis L.)
Conventional methods of pear breeding, largely based on intra- and inter-specific hybridization, are difficult because pear is highly heterozygous, polygenic and has a long juvenile period. Genetic improvements of pear cultivars are possible through induction of mutations and gene transfer by genetic engineering. A general prerequisite for these approaches is to establish an efficient plant reg...
