Pollination triggers female gametophyte development in immature Nicotiana tabacum flowers
In Nicotiana tabacum, female gametophytes are not fully developed at anthesis, but flower buds pollinated 12 h before anthesis produce mature embryo sacs. We investigated several pollination-associated parameters in N. tabacum flower buds to determine the developmental timing of important events in preparation for successful fertilization. First, we performed hand pollinations in flowers from s...
متن کاملDevelopmental Instability in Leaves and Flowers of NICOTIANA TABACUM.
O R G A N S which are periodically repeated in plants show a more or less quantitative variation in spite of being governed by the same genotype. This variation is considered to be due, in addition to local fluctuation in environmental conditions outside and/or inside the plant body, to mistakes in the developmental course of organs resulting probably from the intrinsic nature of the organisms....

In the 16 th century, Europeans spread the use of tobacco in North America, while the Spanish bring it into Europe. In the 1559, Jean Nicot, the French am...
متن کاملLipopolysaccharide-responsive phosphoproteins in Nicotiana tabacum cells.
Mounting evidence is merging to affirm the effectiveness of bacterial lipopolysaccharides (LPS) as biological control agents, inducers of innate immunity, and to stimulate/potentiate the development of defense responses in plants through protein phosphorylation-mediated signal perception/transduction responses. In vivo labeling of protein phosphorylation events during signal transduction indica...
متن کاملInduction of Ethylene Biosynthesis in Nicotiana tabacum
Xylanase (EIX) from the fungus Trichoderma viride elicits ethylene biosynthesis in leaf tissues of Nicotiana tabacum cv Xanthi but not in cv Hicks. The increase in ethylene biosynthesis is accompanied by an accumulation of 1-aminocyclopropane-1-carboxylic acid (ACC), an increase in extractable ACC synthase activity, and increases in ACC synthase and ACC oxidase transcripts. Priming of leaves wi...
