15 صفحه اولRegulation of actin dynamics in pollen tubes: control of actin polymer level.
Actin cytoskeleton undergoes rapid reorganization in response to internal and external cues. How the dynamics of actin cytoskeleton are regulated, and how its dynamics relate to its function are fundamental questions in plant cell biology. The pollen tube is a well characterized actin-based cell morphogenesis in plants. One of the striking features of actin cytoskeleton characterized in the pol...
متن کاملThe regulation of actin organization by actin-depolymerizing factor in elongating pollen tubes.
Pollen tube elongation is a polarized cell growth process that transports the male gametes from the stigma to the ovary for fertilization inside the ovules. Actomyosin-driven intracellular trafficking and active actin remodeling in the apical and subapical regions of pollen tubes are both important aspects of this rapid tip growth process. Actin-depolymerizing factor (ADF) and cofilin are actin...
متن کاملDifferent modes of plant regeneration and factors affecting in vitro bulblet production in Ornithogalum virens
Efficient procedures are outlined for plant regeneration through direct shoot bud formation and indirect organogenesis through callus formation in Ornithogalum virens Lindl using bulb scale as explant. Murashige and Skoog’s (MS) medium containing 1 mg/L (5.4mM) NAA and 2 mg/L (4.4mM) BA was most effective in direct induction of shoot buds from explant. Callus cultures were raised from the bulb ...
متن کاملOscillatory increases in alkalinity anticipate growth and may regulate actin dynamics in pollen tubes of lily.
Lily (Lilium formosanum or Lilium longiflorum) pollen tubes, microinjected with a low concentration of the pH-sensitive dye bis-carboxyethyl carboxyfluorescein dextran, show oscillating pH changes in their apical domain relative to growth. An increase in pH in the apex precedes the fastest growth velocities, whereas a decline follows growth, suggesting a possible relationship between alkalinity...
