根据文章第一段“Pollination (授粉) is important for the reproduction of many plants. Some rely on the wind or water for pollination, but most depend on animals to serve as the pollinators. Insects like bees, moths, and beetles also serve as the pollinators, helping with this process. (...
This chapter broadly covers the modes of reproduction in crop plants. The knowledge of the reproductive biology, life cycle, and type of cultivars are important for plant breeders to develop appropriate breeding strategies. Information on sexual and asexual modes of reproduction and propagation in ...
The enormous diversity of life forms on earth has been driven in part by the processes of sex and recombination that evolved in single-celled organisms and amplified in multicellular organisms. The primary advantage of sexual reproduction is increased genetic diversity proposed by Weismann (1889), an...
Unexpectedly, however,C. purpureushas only one of each type of sex chromosome. Perhaps the two Us and Vs each somehow became fused into a single one. Alternatively, perhaps one copy of each was lost; this might be possible, provided that each sex chromosome carries a dominant factor ensuring...
Bateman's principle and plant reproduction: The role of pollen limitation in fruit and seed set Bateman's principle states that male fitness is usually limited by the number of matings achieved, while female fitness isusually limited by the resources ... Martin,Burd - 《Botanical Review》 被引...
type I systems, Cas3, provides a new approach for the introduction of large chromosomal deletions adjacent to Cascade DNA targets13. Finally, being comprised of 8–11 proteins, Cascade provides multiple structural options for the attachment and recruitment of accessory domains with new functionalities...
pests, as well as the occurring resources in the agricultural landscape. Flowering plants are, in many cases, among the most important natural resources for arthropods, because many of them rely on flowering resources for survival and reproduction in some stages of the life cycle (e.g., [3]...
Thus, an experimental reproduction of the poisoning was carried out with 5 sheep by administering 30–60 g of leaves per kilogram of body weight, and two sheep with doses of 5–10 g of seeds per kilogram of body weight, with samples from different regions of Brazil. All sheep showed ...
When plants are subjected to high light, the energy distribution between photosystem I (PSI) and PSII becomes unbalanced, leading to a sharp drop in photosynthetic efficiency. As a result, the plant may eventually wither and die. In response to this type of stress, plants employ a variety of...
Cell-surface receptors play pivotal roles in many biological processes, including immunity, development, and reproduction, across diverse organisms. How cell-surface receptors evolve to become specialised in different biological processes remains elusive. To shed light on the immune-specificity of cell-sur...
