Mitochondrial NAD-malic enzyme (ME) and/or cytosolic/plastidic NADP-ME combined with the cytosolic/plastidic pyruvate orthophosphate dikinase (PPDK) catalyze two key steps during light-period malate decarboxylation that underpin secondary CO(2) fixation in some Crassulacean acid metabolism (CAM) species. We report the generation and phenotypic characterization of transgenic RNA interference lin...

physiological effect of six levels of water stress (0, -0.1, -.03, -0.6, -0.9 and -1.2 mp) was studied on seed germination and plumule as well as radicule growth length in three species namely: agropyron elongatum, agropyron desertourm and secale montanum. polyethylene glycol (peg) was used to provide appropriate water potentials. a total of 100 seeds in four replications (petri dishes) were so...

Experiments were conducted in growth chambers to examine the effect of a mild water stress (-200 kilopascals polyethylene glycol) on frond elongation and water status of the ostrich fern (Matteuccia struthiopteris [L.] Todaro). Measurements were taken for two days, starting one day after the application of polyethylene glycol. Total water potential in control (well-watered) plants was always si...

Ochrobactrum species are widespread in the environment and can colonize a wide variety of habitats. Here, we describe the sequencing of a new environmental isolate of Ochrobactrum anthropi isolated from northern Vietnam.

The level and pattern of nucleotide variation in duplicate gene provide important information on the evolutionary history of polyploids and divergent process between homoeologous loci within lineages. Kengyilia is a group of allohexaploid species with the StYP genomic constitutions in the wheat tribe. To investigate the evolutionary dynamics of the Pgk1 gene in Kengyilia and its diploid relativ...

Identification of the genetic architecture of phenotypic stability and management of adaptational genes is a prerequisite for improvement of adaptation. To locate the genes controlling adaptation, disomic addition lines of agropyron (agropyron elongatum, 2n=2x=14) into the genetic background of bread wheat (Triticum aestivum L., 2n=6x=42, cv. ‘Chinese Spring’=CS) were used in a randomized compl...

The life cycles of two plant species in the Mediterranean chaparral, the evergreen Arbutus andrachne and the deciduous Rhamnus lycioides, were studied, as were the cycles of two stenophagous whitefly species that live on them, Trialeurodes lauri and Dialeurolobus rhamni, respectively. Trialeurodes lauri is univoltine, diapausing from June to March corresponding to the plant’s leaf dormancy. The...

BACKGROUND AND AIMS Leaf longevity is an important plant functional trait that often varies with soil nitrogen supply. Ethylene is a classical plant hormone involved in the control of senescence and abscission, but its role in nitrogen-dependent leaf longevity is largely unknown. METHODS Pot and field experiments were performed to examine the effects of nitrogen addition on leaf longevity and...
