Long-range signalling in plant reproductive development

Long-range signalling in plant reproductive development.

Animals and plants produce regulatory signals at specific places of their bodies, in order to regulate developmental events which take place at a distance. Plants use this mechanism to adjust their development to the changing environment. Flowering and tuber formation are controlled by signals generated in the leaves that travel throughout the plant to reach their target tissues: the shoot apic...

The Neural Network Modeling Approach for Long Range Expansion Policy of Power Plant Ccenters

Traditionally, Electrical power plant capacities are determined after specific plant locations have been selected. In this paper an expansion policy of power plant centers involving the choice of regions that must be allocated to power plant centers and power plant centers capacities over a specified planning horizon (years) is tackled. The problem is performed as a mixed integerprogramming mod...

Plant Development: How Long Is a Root?

The plant hormone cytokinin controls root growth by balancing the division and differentiation of stem cells. But what controls accumulation of cytokinin? A new study has identified a regulatory loop between a transcription factor, PHABULOSA, and cytokinin biosynthesis that creates robust domains of cytokinin activity.

Development of Long Range Order in MCM-41

MCM-41 is largely an amorphous silicate. The small angle diffraction peaks arise from the repeat distances between the hexagonally close packed channel system, rather than from regular atomic repeat distances. The silica framework gives no Bragg peaks suggesting shorter-range order. The number of peaks in the diffraction pattern therefore reflects the degree of long-range order monodispersity a...
