Plant Fertilization: Maximizing Reproductive Success
Sperm competition does not occur in flowering plants as typically only a single pair of sperm cells is delivered for double fertilization. Two recent reports show that plants are capable of avoiding reproductive failure when defective sperm cells are released.
متن کاملPlant Fertilization: Bursting Pollen Tubes!
Higher plants don't have motile sperm; they rely on pollen tubes to deliver them. Recent research has identified key components involved in pollen tube tip bursting that allow sperm release and fertilization.
متن کاملMycorrhizal Fungi and Plant Nutrition
The term “mycorrhiza” was coined by A. B. Frank, a scientist in Germany, more than 100 years ago. It literally means fungus-root, and describes the mutualistic association existing between a group of soil fungi and higher plants. The association is based on the plant component providing carbohydrates and other essential organic compounds to the fungi. In return, the fungal component, which colo...

متن کاملResolving the ‘nitrogen paradox’ of arbuscular mycorrhizas: fertilization with organic matter brings considerable benefits for plant nutrition and growth
Arbuscular mycorrhizal fungi (AMF) can transfer nitrogen (N) to host plants, but the ecological relevance is debated, as total plant N and biomass do not generally increase. The extent to which the symbiosis is mutually beneficial is thought to rely on the stoichiometry of N, phosphorus (P) and carbon (C) availability. While inorganic N fertilization has been shown to elicit strong mutualism, c...
