Abstract
Pollen interaction with the environmental factors represents a potential bottleneck that can drastically limit reproductive success both in rare and in crop species. Among environmental constraints, high temperatures and humidity are well known to affect pollen viability, pollen germinability and fertilization success. Negative effects of high temperature before pollen development have been described on microsporogenesis of several species. Despite the general knowledge on the effect of temperature on plant reproduction, studies aimed at investigating possible implications of heat stress induced aberrations on the later gametogenesis phases have been generally neglected. All research activities carried out during the Ph.D. aimed to bridge this gap of knowledge deepening the effect of the main factors affecting pollen functionality. This approach was applied both to wild species threatened with extinction and to crop species. In the first case the main aim was to contribute at identifying the bottleneck limiting the generation turnover and the long-term conservation of the species. For crops the main goal was to analyse the species resilience to environmental factors in a scenario of climate changes. Additionally, the approach of analysing the interaction between plants and environmental factors was also extended to space factors, and more specifically to altered gravity conditions. These research activities were aimed at contributing to succeed in the long-term mission to Moon and Mars by using plants in Bioregenerative Life Support Systems.
