The sucrose (Suc) H(+)-cotransporter StSUT1 from potato (Solanum tuberosum), which is essential for long-distance transport of Suc and assumed to play a role in phloem loading in mature leaves, was found to be expressed in sink tubers. To answer the question of whether SUT1 serves a function in phloem unloading in tubers, the promoter was fused to gusA and expression was analyzed in transgenic ...
crisis due to global warming and its associated damaging consequences, including salinity, it is essential to develop plant resistance to salinity level. in this study, an experiment was conducted using different levels of salinity (0.05, 0.1, 0.15 and 0.2% sodium chloride) had on rosa hybrida, as the most important cut flowers in the world. results showed that by increasing of salinity, sodium...
Soluble starch synthase I (SSSI) cDNA was isolated from taro (Colocasia esculenta var. esculenta) by RT-PCR and rapid amplification of cDNA ends reaction. The transcript of this single-copy gene is 2340 bp and encodes 642 amino acids protein containing a putative transit peptide of 54 residues. Recombinant SSSI protein displayed both primer-dependent and primer-independent activities of starch ...
The relative magnitude of general combining ability (gca) and specific combining ability (sca) effects in three generations (years), viz. Seedling (SG), first clonal generation (FCG) and second clonal generation (SCG) for tuber yield, tuber number, average tuber weight and tuber dry matter of potato in a line x tester mating design (10 × 4) was studied. There were marked differences in the gca ...
Potato is a strategic crop in Tunisia but is susceptible to many pests and diseases. Nematodes of the genera Meloidogyne and Globodera are important pests that cause yield losses and depreciation of tuber quality. A trial was carried out in a plot where the soil was naturally infested with M. javanica and G. pallida. Three soil treatments were tested and compared. Soil solarization (SS) and inc...
Trehalose-6-phosphate (T6P) is a signaling metabolite that regulates carbon metabolism, developmental processes, and growth in plants. In Arabidopsis (Arabidopsis thaliana), T6P signaling is, at least in part, mediated through inhibition of the SNF1-related protein kinase SnRK1. To investigate the role of T6P signaling in a heterotrophic, starch-accumulating storage organ, transgenic potato (So...
This experiment was carried out during the two growing seasons 2012/2013 and 2013/2014 at the experimental farm of Unit for Strawberry and Non Traditional Horticulture Crops, Horticulture Department, Faculty of Agriculture, Ain Shams University, Egypt, in order to investigate the effect of magnetic field on germination of true potato seeds (TPS), vegetative growth and potato tubers characterist...
The active turnover of chlorogenic acid (3-caffeoylquinic acid(3)), a major phenolic component of Xanthium leaves and potato tuber disks, has been demonstrated in these tissues. Pulse-labelling experiments with radioactive l-phenylalanine and trans-cinnamic acid as well as direct feeding experiments with chlorogenic acid-(14)C labelled in the caffeoyl moiety have been employed in the turnover s...
Steroidal glycoalkaloids occur in potatoes and are reported to impart resistance to phytopathogens including bacteria, fungi, and insects. Because glycoalkaloids can be passed to progenies during breeding programs designed to develop improved potatoes, it is of importance to determine the quality of desired characteristics and the composition of glycoalkaloids of new somatic hybrids. The object...
potato virus y (pvy) and potato leafroll virus (plrv) are two major viruses which reduce 10-90 percent of yield and quality of potato tubers. in the present study, the efficiency of different methods, including meristem culture, thermotherapy followed by meristem culture and electerotherapy followed by meristem culture in two cultivars (agria and marfona) infected by plrv or pvy were evaluated....
