Mitochondria are subcellular organelles with an essentially oxidative type of metabolism. The production of reactive oxygen species (ROS) in it increases under stress conditions and causes oxidative damage. In the present study, effects of exogenous sodium nitroprusside (SNP), a nitric oxide (NO) donor, on both the ROS metabolism in mitochondria and(More)
The tuberous root of radish is an important vegetable, but insufficient transcriptomic and genomic data are currently available to understand the molecular mechanisms underlying tuberous root formation and development. High-throughput transcriptomic sequencing is essential to generate a large transcript sequence data set for gene discovery and molecular(More)
S-adenosyl-L-methionine (SAM) synthetase is the key enzyme involved in the biosynthesis of SAM, which serves as a common precursor for polyamines (PAs) and ethylene. A SAM synthetase cDNA (SlSAMS1) was introduced into the tomato genome using the Agrobacterium tumefaciens transformation method. Transgenic plants overexpressing SlSAMS1 exhibited a significant(More)
A heuristic algorithm for multiple vehicles routing problem with stochastic demand is proposed and the goal is to minimize the total traveling cost. Two-phase method is adopted to deal with this problem. In the first phase, an algorithm is proposed to partition customers into clusters, and the main task of the second phase is to design an effective routing(More)
The study showed that in solar greenhouse continuously cropped cucumber soil, phenolic acids p-hydroxybenzoic acid, ferulic acid and benzoic acid had an obvious accumulation with increasing cropping year, and their contents were significantly higher after continuously cropped for 5 approximately 9 years than for 1 approximately 3 years. With the increasing(More)
Nitric oxide (NO) and auxin (indole-3-acetic acid; IAA) play vital roles in regulating plants tolerance to abiotic stresses. This study showed that both NO and IAA could induce cucumber plants tolerance to sodic alkaline stress, which depended on their roles in regulating reactive oxygen species (ROS) scavenging, antioxidative enzymes activities, Na(+)(More)
In this research, biological function of CsNMAPK, encoding a mitogen-activated protein kinase of cucumber, was investigated under salt and osmotic stresses. Northern blot analysis showed that the expression of CsNMAPK was induced by salt and osmotic stresses in the cucumber root. In order to determine whether CsNMAPK was involved in plant tolerance to salt(More)
Pakchoi (Brassica rapa L. ssp. chinensis), a kind of Chinese cabbage, is an important vegetable in Asian countries. Agrobacterium mediated in planta vacuum infiltration transformation has been performed in pakchoi since 1998, but a detailed study on this technique was lacking. Pakchoi plants 40–50 days old with inflorescences were vacuum infiltrated with(More)
To unravel the roles of sucrose phosphate synthase (SPS) in muskmelon (Cucumis melo L.), we reduced its activity in transgenic muskmelon plants by an antisense approach. For this purpose, an 830 bp cDNA fragment of muskmelon sucrose phosphate synthase was expressed in antisense orientation behind the 35S promoter of the cauliflower mosaic virus. The(More)
