A study by Kobe University botanist Kenji Suetugu reveals that certain fungus-eating orchids, like Stigmatodactylus sikokianus, predominantly self-pollinate after three days, ensuring reproductive success. This delayed mechanism may drive the evolution of combined self- and outcrossing methods to avoid inbreeding.
This study found that nucleo-cytoplasmic interaction is a crucial factor in male sterility of seedless cybrid citrus, affecting stamen development and pollen abortion. The researchers identified genes involved in stamen development and proposed a potential nucleo-cytoplasmic interaction network.
A new study found that mobile stamens on flowers help reduce the time insects linger on flowers, decreasing nectar consumption while increasing pollen transport efficiency. This allows for more efficient pollination, ultimately benefiting plant reproductive success.
Researchers discovered that vibrating stamens, pollen-bearing organs of flowers, are a key trait for understanding early stages in the transition from insect to wind pollination. This finding helps explain why some flowering plant species have evolved to rely on wind instead of insects for pollination.
A 99-million-year-old flower fossil discovered in Burmese amber sheds light on the sudden appearance of angiosperms. The find indicates that Core Eudicots, a group including apple and cherry trees, flourished on Earth around 100 million years ago.
After 100 years of misidentification, researchers have confirmed the existence of Kadsura matsudae, a distinct East Asian vine species. The discovery was made by collaborating experts from Japan and Taiwan, who utilized molecular analysis to distinguish it from previously thought to be Kadsura japonica.
Researchers found a small molecule, microRNA, essential for controlling floral organs' identity in plants. This discovery contradicts the long-held ABC model of floral organ development, suggesting a more complex temporal control mechanism.
