Significance Cell–cell communication is a prerequisite of multicellular development and noncell autonomous stem cell induction has been conserved during evolution. Cytoplasmic bridges, called plasmodesmata, which facilitate the exchange molecules between neighboring cells, are striking innovation for cell–cell signaling in plants. Here, we show that plasmodesmata function required activity shoot apical cells Arabidopsis provide evidence inducing transcription factor WUSCHEL moves from niche...
A major feature of embryogenesis is the specification stem cell systems, but in contrast to situation most animals, plant cells remain quiescent until postembryonic phase development. Here, we dissect how light and metabolic signals are integrated overcome dormancy at shoot apical meristem. We show on one hand that able activate expression inducer WUSCHEL independently photosynthesis this likely involves inter-regional cytokinin signaling. Metabolic signals, other hand, transduced meristem...
To maintain the balance between long-term stem cell self-renewal and differentiation, dynamic signals need to be translated into spatially precise temporally stable gene expression states. In apical plant system, local accumulation of small, highly mobile phytohormone auxin triggers differentiation while at same time, pluripotent cells are maintained throughout entire life-cycle. We find that resistant mediated but require low levels signaling for their maintenance. demonstrate WUSCHEL...
The presence of a large central vacuole is one the hallmarks prototypical plant cell, and multiple functions this compartment require massive fluxes molecules across its limiting membrane, tonoplast. Transport assumed to be energized by membrane potential proton gradient established combined activity two pumps, vacuolar H+-pyrophosphatase (V-PPase) H+-ATPase (V-ATPase). Exactly how labor divided between these enzymes has remained elusive. Here, we provide evidence using gain-...
RNA silencing is one of the main defense mechanisms employed by plants to fight viruses. In change, viruses have evolved suppressor proteins neutralize antiviral silencing. Since endogenous and functions pathway rely on common components, it was suggested that viral suppressors interfere with contributing symptom development. this work, we aimed understand effects tombusviral p19 during genuine virus infection. We showed ectopically expressed sequesters small RNAs (sRNAs) in absence, but not...
Plant development is continually fine-tuned based on environmental factors. How perturbations are integrated into the developmental programs and how poststress adaptation regulated remains an important topic to dissect. Vegetative reproductive phase change a very transition that complexly endogenous exogenous cues. Proper timing of flowering vital for success. It has been shown previously AGAMOUS LIKE 16 (AGL16), MADS-box transcription factor negatively regulates time through FLOWERING LOCUS...
Predators influence the behaviour of prey and by doing so they potentially reduce pathogen transmission a vector. Arthropod predators have been shown to consumption plant biomass pest herbivores, but their cascading non-consumptive effect on vector insects' feeding subsequent has not investigated experimentally before. Here we examined predator-mediated mechanisms using Wheat Dwarf Virus that is transmitted leafhopper, Psammotettix alienus. We applied in situ hybridization localize which...
Summary In some plant–virus interactions plants show a sign of healing from virus infection, phenomenon called symptom recovery. It is assumed that the meristem exclusion essential to this process. The discovery RNA silencing provided possible mechanism explain and Here we evidence not reason for in Nicotiana benthamiana infected with Cymbidium ringspot (CymRSV). Transcriptome analysis followed by situ hybridization shed light on changes gene expression shoot apical (SAM) infection. We...
