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…

Focus Issue on Cellular Dynamics (January 2018) Editors: Dan Szymanski, Diane Bassham, Teun Munnik, and Wataru Sakamoto Submission Deadline: June 5, 2017 To be published in January 2018, this focus issue will provide a series of invited Update Reviews on hot topics in plant cell biology,…

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…

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…

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…

Clocks in green algae have been described as simple two-gene loops, while clocks in angiosperms have evolved to complex interlocked loops. This striking jump in complexity led Linde et al. to investigate the clocks in bryophytes and charophytes to shed light on this transition. First, through the sequence…

Drought tolerance is a complex trait, and Avramova et al. show that there is more than one way to be drought tolerant. Specifically, they investigate the role of antioxidants in supporting leaf growth in several varieties of drought tolerant maize. As compared to the tolerant lines, drought sensitive…

Rubisco (Ribulose-1,5-biphosphate carboxylase/oxygenase) is the key enzyme in photosynthetic carbon fixation. In C3 plants, the enzyme is usually found in mesophyll cells and guard cells, but it also can be found in photosynthetic glandular trichomes such as those found in tobacco. Laterre et al. used…
