The effect of exogenous CaCl2 on photosynthesis, antioxidant system, and chloroplast ultrastructure of tomato leaves under low night temperature (LNT) was investigated. Tomato seedlings were pretreated with 27 mM CaCl2, 5 mM EGTA, respectively, for 4 days and then exposed to LNT treatment at 6 °C for 7 days. Plants treated with CaCl2 showed higher(More)
In order to investigate the regulation effect of Ca2+ and salicylic acid (SA) on the sub-high temperature resistance of tomato plants, the plants were treated with sub-high temperature (35 degrees C) at day time during their 1st inflorescence flowering, and CaCl2 (10 mmol x L(-1)) and SA (0.2 mmol x (L(-1 were foliar sprayed to study the variations of the(More)
The most important quality for muskmelon (Cucumis melo L.) is their sweetness which is closely related to the soluble sugars content. Leaves are the main photosynthetic organs in plants and thus the source of sugar accumulation in fruits since sugars are translocated from leaves to fruits. The effects of grafting muskmelon on two different inter-specific(More)
FIP-fve is a bioactive protein isolated from the mushroom Flammulina velutipes, which belongs to the fungal immunomodulatory protein (FIP) family and demonstrates several kinds of biological activities including anti-allergy, anti-tumor and immunomodulation. In the current study, the FIP-fve gene was cloned and expressed in the yeast Pichia pastoris GS115,(More)
UNLABELLED The control of abscission is an important agricultural concern because of its substantial effect on crop yield and quality. Changes in gene expression are correlated with the ethylene-mediated execution of abscission. However, only few large-scale proteomic studies focused on tomato pedicel abscission. Isobaric tag for relative and absolute(More)
LpGPAT was obtained from L. pensylvanicum using RT-PCR and rapid amplification of cDNA ends. The cloned full-length cDNA was 1544 bp; it encoded 410 amino acids and had a molecular size of 46 KDa. The nucleic acid sequence analysis showed that it shared high homology with other known GPATs. SMAT result suggests that there is a PlsC that exists in 176-322(More)
Polygalacturonase (PG) is crucial in plant organ abscission process. This paper investigated the cellular and subcellular localization of PG in ethylene-stimulated abscission of tomato pedicel explants. Confocal laser scanning microscopy of abscission zone sections with the fluorescent probe Cy3 revealed that PG was initially accumulated in parenchyma cells(More)
This is the first reported proteomic analysis to study the dormancy breaking of Magnolia sieboldii seeds. Our results provide a fundamental reference for further studies on the regulation of protein expression during seed germination. Magnolia sieboldii K. Koch is an ornamental tree. The deep dormancy of its seeds hinders its cultivation for economic(More)
Tomato seedlings were treated with 15 degrees C (control), 12 degrees C, 9 degrees C, and 6 degrees C at night for seven days to study the changes of their leaf photosynthesis and chloroplast ultrastructure, aimed to make sure the recovery effect of the photosynthesis of tomato leaves after a short-term low nocturnal temperature. The results showed that(More)
By using aeroponics culture system, this paper studied the effects of elevated rhizosphere CO2 concentration on the leaf photosynthesis and the fruit yield and quality of muskmelon during its anthesis-fruiting period. In the fruit development period of muskmelon, as compared with those in the control (350 microL CO2 x L (-1)), the leaf chlorophyll content,(More)
