Compositional and Morphological Analysis of Salt Stress Tolerant Mannitol-1-phosphate Dehydrogenase (mtlD)-Transgenic Potato Plants.

Undesired effects often occur in genetically modified (GM) plants, especially during metabolite engineering. Nevertheless, conducting a comparative study between GM and non-GM plants can identify the unintended alterations and facilitate the risk assessment of GM crops. This research compared the morphology and composition of a transgenic potato plant expressing mannitol-1-phosphate dehydrogenase (mtlD), with its non-transgenic counterpart.

Molecular Control of Sporophyte-Gametophyte Ontogeny and Transition in Plants.

Alternation of generations between a sporophytic and gametophytic developmental stage is a feature common to all land plants. This review will discuss the evolutionary origins of these two developmental programs from unicellular eukaryotic progenitors establishing the ability to switch between haploid and diploid states. We will compare the various genetic factors that regulate this switch and highlight the mechanisms which are involved in maintaining the separation of sporophytic and gametophytic developmental programs.

Comparative compositional analysis of transgenic potato resistant to potato tuber moth (PTM) and its non-transformed counterpart.

In this study, the compositions of transgenic potatoes (TPs) resistant to potato tuber moth (Phthorimaea operculella) were compared with those of its non-transgenic (NTP) counterparts. The light inducible promoter, phosphoenolpyruvate carboxylase led to the expression of Cry1Ab only in the leaves and light-treated tubers of the TPs. No significant differences were found in the moisture, ash, dry weight, total soluble protein, carbohydrate, starch, fiber, ascorbate, cations, anions, fatty acids, and glycoalkaloids contents of TP and NTP.
