Plant Organogenesis: Rules of Order

Plant Organogenesis: Rules of Order

Plant lateral roots have a defined developmental pattern and shape, but a key question is whether strict regulation underlies observed regularity. A new study uses long-term in toto live imaging and simulations to show that organogenesis rather follows self-organizing principles.

Effect of Vitamins on In Vitro Organogenesis of Plant

Vitamins are necessary compounds synthesized and utilized in plants. In tissue culture media, vitamin addition is not always common; since the amount needed by plants is relatively unknown and varies. Vitamins, in combination with other media constituents, have been shown to have direct and indirect effects on callus growth, somatic growth, rooting, and embryonic development. For example, diffe...

Plant hormonal regulation of nitrogen-fixing nodule organogenesis.

Legumes have evolved symbiotic interactions with rhizobial bacteria to efficiently utilize nitrogen. Recent progress in symbiosis has revealed several key components of host plants required for nitrogen-fixing nodule organogenesis, in which complicated metabolic and signaling pathways in the host plant are reprogrammed to generate nodules in the cortex upon perception of the rhizobial Nod facto...

First-Order Formative Rules

This paper discusses the method of formative rules for firstorder term rewriting, which was previously defined for a higher-order setting. Dual to the well-known usable rules, formative rules allow dropping some of the term constraints that need to be solved during a termination proof. Compared to the higher-order definition, the first-order setting allows for significant improvements of the te...
