We recently cloned MtVP1, a type I vacuolar-type H(+)-translocating inorganic pyrophosphatase from Medicago truncatula. In the present study, we investigated the cellular location and the function of this H(+)-PPase in Arabidopsis and potato (Solanum tuberosum L.). An MtVP1::enhanced green fluorescent protein fusion was constructed, which localized to the plasma membrane of onion epidermal cell...
Annexins are a family of calcium- and membrane-binding proteins that are important for plant tolerance to adverse environmental conditions. Annexins function to counteract oxidative stress, maintain cell redox homeostasis, and enhance drought tolerance. In the present study, an endogenous annexin, STANN1, was overexpressed to determine whether crop yields could be improved in potato (Solanum tu...
Transgenic plants and their products are being developed day by day due to their improved characteristics, and it is necessary to evaluate the safety of these plants before releasing them. Hence, the importance of the issue of biosafety of transgenic plants and the use of their products has led the regulatory agencies to create some laws called substantial equivalence. based on that, the essent...
Colorado Potato Beetle, Leptinotarsa decemlineata (Say) is a serious pest of potato plants and devastates additional crops such as eggplant, tomato, pepper, and tobacco by its voracious feeding. Plants of the Lamiaceae family produce a large number of polyphenols with insecticidal activity. In this study we tried to identify if some of these compounds could be used as antifeedants and if there ...
The effect of Bt-cry1Ia1 (cryV now designated cry1Ia1 under revised nomenclature) of potato transgenic plants on the two species of potato tuber moth, Phthorimaea operculella (Zeller) and Symmetrischema tangolias (Gyen), was tested in Peru. Detached leaf bioassays were done using 10 neonate larvae per replication on each transgenic line of bred potato varieties Atlantic and Spunta. Mortality in...
In late summer, heteroecious aphids, such as the potato aphid, Macrosiphum euphorbiae, move from their secondary summer host plants to primary host plants, where the sexual oviparae mate and lay diapausing eggs. We tested the hypothesis that volatiles of the primary host, Rosa rugosa, would attract the gynoparae, the parthenogenetic alate morph that produce oviparae, as well as the alate males ...
To examine which sequences are involved in regulating the potato sucrose synthase gene Sus3-65, we examined a series of deletion and substitution constructs in transgenic potato and tobacco plants. In a construct containing 3.9 kb of 5' flanking region, substitution of the native 3' sequence with the nopaline synthase 3' sequence and deletion of the leader intron did not significantly affect ex...
This study reports the development of a loop-mediated isothermal amplification procedure (LAMP) for polymerase chain reaction (PCR)-based detection of 'Candidatus Liberibacter solanacearum', the bacterial causal agent of potato zebra chip (ZC) disease. The 16S rDNA gene of 'Ca. Liberibacter solanacearum' was used to design a set of six primers for LAMP PCR detection of the bacterial pathogen in...
Oxidative stress is a major threat for plants exposed to various environmental stresses. Previous studies found that transgenic potato plants expressing both copper zinc superoxide dismutase (CuZnSOD) and ascorbate peroxidase (APX) (referred to as SSA plants), or nucleoside diphosphate kinase 2 (NDPK2) (SN plants), showed enhanced tolerance to methyl viologen (MV)-induced oxidative stress and h...
