Anther and Pollen: From Biology to Biotechnology by Christophe Clement, Ettore Pacini, Jean-Claude Audran

By Christophe Clement, Ettore Pacini, Jean-Claude Audran

Pollen, the plant constitution most generally utilized by people, is a key constitution in plant replica giving upward thrust to end result and seeds. in addition, the biotechnological use of pollen is of significant significance for plant breeders because it permits to procure kinds with greater usage and yield. within the first half, the successive steps of pollen improvement within the anther from floral induction to pollen germination and fertilization are completely tested; the second one half is dedicated to pollen behaviour in vitro.

Metaphor and Iconicity: A Cognitive Approach to Analysing Texts

Metaphor and Iconicity makes an attempt to explain the interaction of metaphor and iconicity within the construction and interpretation of spoken and written texts from a cognitive viewpoint. there are lots of levels within which metaphor and iconicity appear themselves, starting from sound symbolism and parallelism in poetic discourse to observe order, inflectional varieties, and different grammatical constructions in traditional discourse.

Few philosophers are as largely learn or as broadly misunderstood as Nietzsche. during this e-book, Tsarina Doyle units out to teach in particular Kantian-informed technique lies on the middle of Nietzsche's method of epistemology and metaphysics. the writer claims, contentiously, that either Nietzsche's early and overdue writings might be understood as responses to Kant's constitutive-regulative contrast on the point of epistemology and to his remedy of strength and effective causality on the point of metaphysics

This can be a serious inquiry into the connections among emergent feminist ideologies in China and the creation of 'modern' women's writing from the dying of the final imperial dynasty to the founding of the PRC. It accentuates either famous and under-represented literary voices who intervened within the gender debates in their iteration in addition to contextualises the concepts utilized in imagining substitute tales of woman adventure and power.

In male ovaries on the other hand this ratio was always less than 1 due to the disappearance of putrescine in TCA-insoluble fraction (Figs. 4-5). At anthesis higher polyamine biosynthetic activities (ODC, ADC and SAMDC) were detected in male ovaries in comparison with the female ones, especially with regard to SAMDC (Fig. 6). 40 Biasi et al. 4 Discussion We have investigated the physiology of male and female flower development in kiwiplants as a first step to study sex determination in dioecious plants and the possibility to use polyamines as markers of sexual differentiation.

The assay was carried out as previously described (Bagni et al. 1983), with minor modification (Beckman Tissue Solubilizer 450, Beckman, instead of Protosol, NEN).

This allowed us to identify 5 partial cDNAs located on the Y chromosome. The location of these genes was confirmed by segregation analysis using Southern blot analysis: each of the cDNA hybridised to a genomic DNA fragment which strictly segregates with the male plants. Interestingly, all 5 clones seem to have a homologue on the X chromosome. The sequence analysis of these clones revealed that they are all similar to EST sequences (Expressed ~equence lags) of Arabidopsis or rice. One of them has 2 calcium binding domains similar to those found in calmodulin.
