Abstract:
... A diverse set of cultivars in the genus Citrus have been recognized as derived from the natural hybridization of several founder cultivars. However, knowledge regarding the process of domestication and diversification of modern citrus cultivars from these founders is quite limited. We recently identified the parent(s) of 67 citrus cultivars. Three unique aspects were revealed by the inferred paren ...

Abstract:
... Factors such as the stage of ovule maturity and longevity at flowering, when the stigma is able to receive the pollen, are significant in terms of fruit set. Various abnormalities during ovule development can often limit pollination, effective pollination period (EPP) and fruit set. In the plum cultivar ‘Pozna Plava’ (Prunus domestica L.), in the ovaries of open-pollinated flowers and of emasculat ...

Abstract:
... Most tea plants (Camellia sinensis) are self-incompatible. Self-incompatibility is critical for preventing inbreeding depression and maintaining genetic diversity, but it can hinder breeding and genetic studies. Originally, the propose of this study was to identify fathers of 16 elite F1 individuals derived from open-pollinated seeds of an anthocyanin-rich tea cultivar ‘Ziyan’. In order to achieve ...

Due to these conditions Apidae do not survive during the flowering season of this species. Some syrphids were observed at anthesis collecting nectar. Although the disposition of floral pieces, humid stigma and retractable stamens could suggest ...

Abstract:
... The population characteristics of distylous species are highly sensitive to stochastic natural selection pressure. Therefore, populations growing under different environmental conditions may vary in floral morph ratios, potentially affecting female fitness and leading to inbreeding depression. However, the variation in offspring quality among populations as a result of inbreeding depression is poo ...

Abstract:
... Genetic variance includes both additive and non-additive components, and the latter can be partitioned into dominance and epistatic variance. Additive genetic variance has been the main source of genetic improvement in most tree breeding programs and the genetic gain achieved has mostly been deployed through open-pollinated seed orchards. However, non-additive effects could be exploited in alterna ...

Abstract:
... Epigenetic factors are increasingly being viewed as important mechanisms in organism performance. However, advances in plant epigenetics rely mostly on studies of short-lived model or cultivated species and there is a current gap in knowledge on wild plants, especially on woody plant species, that still needs to be addressed via empirical studies. Through a greenhouse experiment we compared the ge ...
