Auxin and Microtubule Array Patterning
Plant Physiology, Plant Physiology: On The InsideThe Arabidopsis hypocotyl is a valuable model for studying axial growth phenomena in flowering plants owing to its dramatic cell elongation in the absence of cell division and its sensitivity to environmental cues. When grown in the dark, a hypocotyl rapidly elongates, using the energy reserves in the…

The Nuclear Envelope and Stomatal Dynamics
Plant Physiology, Plant Physiology: On The InsideEukaryotic nuclei are double membrane-bound organelles with distinct inner nuclear membranes (INM) and outer nuclear membranes (ONM). The site where the INM and ONM meet forms the nuclear pore, where nucleocytoplasmic transport occurs. Spanning the INM and the ONM are protein complexes known as “linkers…
Open Sesame! Uncovering a Hidden Key Used by Pathogenic Bacteria to Open the Doors Connecting Plant Cells
Research, The Plant Cell, The Plant Cell: In BriefIt has been known for several decades, and suggested as early as the 1930s (Caldwell 1931), that viruses move their proteins and other molecules from one plant cell to the next by altering and regulating plasmodesmata (PD), the tiny doors connecting the cytoplasm between plant cells. And only in the…
Collinear Chromosomes and Shifting Centromeres in the Arabideae
Research, The Plant Cell, The Plant Cell: In BriefFor such an important structure, the centromere certainly is hard to pin down, particularly in regard to the relationship between its sequence composition and epigenetic state and its functions in chromosome pairing and kinetochore formation. In addition to undergoing rapid sequence evolution, centromeres…
Natural Variation in the Amylose Content of Starch
Plant Physiology, Plant Physiology: On The InsideStarch is the major storage carbohydrate in plants. It occurs as semi-crystalline, insoluble granules consisting of two Glc polymers: amylopectin and amylose. Amylopectin, the major polymer, gives rise to the semi-crystalline matrix of the granule. Amylose is believed to reside in amorphous regions…
