Nanoscale movements of cellulose microfibrils in primary cell walls ($)

/
Cell walls are complex mixtures of cellulose microfibrils, proteins and other materials. Their mechanical properties can be measured and modeled, but it is not always simple to translate these measurements to changes at the molecular level. Zhang et al. used atomic force microscopy to provide an unprecedented…

A Salivary Effector Aids in Brown Planthopper Feeding on Rice Plants

/
Herbivory-induced plant cell wall modifications play an important role in deterring herbivory. Modified cell walls not only act as physical defenses against herbivores by enhancing the mechanical hardness of plant tissues but also reduce the digestibility of food for herbivores, thereby functioning as…

Heteroblastic Development of Transfer Cells: A Role for MicroRNA

/
Transfer 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

/
Most 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…
