Abstract
Meiosis is a specialized cell division, essential in most reproducing organisms to halve the number of chromosomes, thereby enabling the restoration of ploidy levels during fertilization. A key step of meiosis is homologous recombination, which promotes homologous pairing and generates crossovers…
Heteroblastic Development of Transfer Cells: A Role for MicroRNA
Plant Physiology, Plant Physiology: On The Inside, ResearchTransfer cells (TCs) play critical roles in membrane transport of solutes at various sites within plants and between plants and their environment. This transport capacity is conferred by inward wall protuberances that extend into the cell lumen. These ingrowths function to enhance the area of surrounding…
Toward Designing Tulips for a Warmer World
Blog, Plant Physiology, Plant Physiology: On The Inside, ResearchMost cultivated tulips (Tulipa gesneriana) are produced in The Netherlands, which has a temperate climate resembling the Central Asian climate in which they originated. The growth cycle of cultivated tulips starts in autumn, when the bulbs are planted in the field. At that time, all organs, including…
Update: Stomatal biology of CAM plants
Plant Physiology: Updates, Plant Science Research Weekly, Research BlogCrassulacean acid metabolism (CAM) plants open their stomata at night, decreasing water loss and increasing water-use efficiency as well as drought tolerance. Males and Griffiths review the stomatal biology of CAM plants as compared to C3 plants. For example, CAM stomata are relatively insensitive to…
Update: Pollen Development at High Temperature: From Acclimation to Collapse
Plant Physiology: Updates, ResearchThe seeds and fruits derived from the sexual reproduction of flowering plants constitute the major part of the human diet. Our capacity to generate sufficient crop yield is increasingly compromised by human population expansion, competition for land use, biodiversity loss, and global climate change.…
Update: Modeling stomatal conductance
Plant Physiology: UpdatesRobust models of stomatal conductance are greatly needed to predict plant-atmosphere interactions in a changing climate, and to integrate new knowledge in physiology and ecological theory. Recent years have brought major advances in the experimental and theoretical understanding underpinning both process-based…
