Many plant species display remarkable developmental plasticity and regenerate new organs after injury. Local signals produced by wounding are thought to trigger organ regeneration but molecular mechanisms underlying this control remain largely unknown. We previously identified an AP2/ERF transcription factor WOUND INDUCED DEDIFFERENTIATION1 (WIND1) as a central regulator of wound-induced cellul...

A small group of pluripotent stem cells in the shoot meristem is the ultimate source for all aerial parts in higher plants: the shoot axis, side branches, leaves and flowers. The stem cells are maintained in an undifferentiated state by signals from an underlying cell group, the organizing center. Genetic and molecular analyses have shown that a feedback signaling loop between stem cells and th...

Objective(s): Omega-3 fatty acids play a key role in maintaining human health. The present study aimed to reduce the fishy smell and taste of omega-3 fatty acids through the encapsulation of lipid vesicles. Materials and Methods: Different non-ionic surfactants from the sorbitan ester family and egg lecithin with cholesterol were utilized to form micro-niosomal and liposomal formulations ...

In white spruce, an improvement of somatic embryo number and quality can be achieved through experimental manipulations of the endogenous levels of reduced (GSH) and oxidized (GSSG) glutathione. An optimal protocol for embryo production included an initial application of GSH in the maturation medium, followed by replacement with GSSG during the remaining maturation period. Under these condition...

In this review, we summarized Monte Carlo Bayesian Reinforcement learning, and explored the possible improvements by proposing better sampling strategy by adaptive sampling. Monte Carlo Bayesian Reinforcement learning is a simple and general approach which samples a finite set of hypotheses from the model parameter space. MC-BRL generates a discrete POMDP that approximates the underlying BRL pr...

The knotted1 (kn1) gene of maize is expressed in meristems and is absent from leaves, including the site of leaf initiation within the meristem. Recessive mutations of kn1 have been described that limit the capacity to make branches and result in extra carpels. Dominant mutations suggest that kn1 function plays a role in maintaining cells in an undifferentiated state. We took advantage of a Ds-...
