sporogenesis meaning in Hindi

Examples

1. Mitotic sporogenesis is a form of asexual reproduction.
2. In some cases, sporogenesis occurs via mitosis ( e . g . in some fungi and algae ).
3. In meiotic sporogenesis, a diploid spore mother cell within the sporangium undergoes meiosis, producing a tetrad of haploid spores.
4. Only their asexual form of reproduction is known, meaning that this group of fungi produce their spores asexually, in the process called sporogenesis.
5. This method of reproduction is found for example in conidial fungi and the red algae " Polysiphonia ", and involves sporogenesis without meiosis.
6. The red alga " Polysiphonia " alternates between mitotic and meiotic sporogenesis and both processes are required to complete its complex reproductive life cycle.
7. In the case of dormant spores in eukaryotes, sporogenesis often occurs as a result of fertilization or karyogamy forming a diploid spore equivalent to a zygote.
8. However, mitotic sporogenesis is an exception and most spores, such as those of plants, most Basidiomycota, and many algae, are produced by meiosis.
9. SPB proteins have roles in leaf development, vegetative phase change, flower and fruit development, plant architecture, sporogenesis, Gibberelic acid signaling and toxin response.
10. Around 60 90 days postinfection, sexual cell stages of the parasite undergo sporogenesis, and develop into pansporocysts, each of which contains eight triactinomyxon-stage spores.
