Bulked segregant analysis combined with specific length amplified fragment sequencing techniques have been applied to determine the fine genetic mapping of fruit flesh thickness-related genes in cucumber. Herein, the Csa2M058670.1 gene was subjected to real time fluorescence quantitative PCR (qRT-PCR) and sequence analysis, indicating a strong correlation with cucumber fruit flesh thickness. Expression...
Over the last 5 decades, runoff from the upstream area of the Yongding River basin has greatly decreased because of changes in the climate and in the intensity of human activities. The Mann-Kendall rank correlation trend test, cumulative anomaly method, and double mass curve of precipitation and runoff were applied to analyse the hydrological sequence trends and altered features in the upstream area...
The toxicity of arsenic (As) in different polluted areas and its effects on human and animal health is a big concern all over the world. Although a wetland ecosystem is a “green filter,” this specific function would be impaired by high As content in wetland sediments. The distribution of As in wetland sediments and its linkages to environmental factors have not been fully explored. In this study,...
Abscisic acid (ABA) plays critical roles in plant growth and development as well as in plants’ responses to abiotic stresses. We previously isolated VvWRKY13, a novel transcription factor, from Vitis vinifera (grapevine), and here we present evidence that VvWRKY13 may regulate ABA biosynthesis in plants. When VvWRKY13 was ectopically expressed in Arabidopsis, the transgenic lines showed delayed seed...
For this study we constructed an integrated evaluation model of water quantity and quality that couples the supply-demand balance system, water consumption balance system, and a simulation model of water quality. In order to realize the dual water supply, the constraint equation of dual water supply has been added in the supply-demand balance system. The water pollution-induced water shortage quantitative...
The cold-responsive (COR) genes play an important role in cold acclimation of higher plants. Here, a tight correlation between chloroplast functionality and COR15A expression, and the functional characterization of Arabidopsis COR15A involved in salt/osmotic stress, were revealed. COR15A gene is light inducible and expressed in light-grown seedlings. The expression level of COR15A was reduced when...
Hydrogen sulfide (H2S) is an important signaling molecule involved in several stress-resistance processes in plants, such as drought and heavy metal stresses. However, little is known about the roles of H2S in responses to chilling stress. In this paper, we demonstrated that chilling stress enhance the H2S levels, the H2S synthetase (L-/D-cysteine desulfhydrase, L/DCD) activities, and the expression...
Anastatica hierochuntica is a monocarpic desert annual whose dry skeletons, enclosing mature fruits, often persist for a number of years. The aerial seed bank in these hygrochastic ‘resurrection plants’ therefore persists too. Life tables and fecundity schedules were constructed for A. hierochuntica populations raised under four water treatments, equivalent to 100, 200, 500 and 1000 mm rainfall. Seedling...
