Supersymmetry in the Standard Sachdev-Ye-Kitaev Model.
Supersymmetry is a powerful concept in quantum many-body physics. It helps to illuminate ground-state properties of complex quantum systems and gives relations between correlation functions. In this Letter, we show that the...
Chaotic-Integrable Transition in the Sachdev-Ye-Kitaev Model.
Quantum chaos is one of the distinctive features of the Sachdev-Ye-Kitaev (SYK) model, N Majorana fermions in 0+1 dimensions with infinite-range two-body interactions, which is attracting a lot of interest as a toy model for...
Photoperiodic control of seasonal growth is mediated by ABA acting on cell-cell communication

In temperate and boreal ecosystems, seasonal cycles of growth and dormancy allow perennial plants to adapt to winter conditions. We show, in hybrid aspen trees, that photoperiodic regulation of dormancy is mechanistically...
A general approach for the liquid phase fragment synthesis of orthogonally protected naturally occurring polyamines and applications thereof

Nov 02, 2019
Orthogonally protected polyamines (PAs) have been synthesized using α,ω-diamines and ω-aminoalcohols as N-Cx-N and N-Cy synthons, respectively, and the Mitsunobou reaction as the key reaction for the assembly of the PA skeleta....

Plant Vascular Biology 2013
About 200 researchers from around the world attended the Third International Conference on Plant Vascular Biology (PVB 2013) held in July 2013 at the Rantapuisto Conference Center, in Helsinki, Finland (http://www.pvb2013.org)....
Plasmodesmata-mediated intercellular signaling during plant growth and development.
Plasmodesmata (PD) are cytoplasmic channels that connect neighboring cells for cell-to-cell communication. PD structure and function vary temporally and spatially to allow formation of symplastic domains during different stages...
Phloem development
Phloem, as a major tissue mediating long-distance communication, has been an object of extensive research ever since its structure was first reported in 1837. Functional phloem consists of sieve elements (SEs) and companion...
Phloem differentiation
Plant vasculature consists of two major conductive cell types, xylem tracheary elements and phloem sieve elements (SEs). Both cell types undergo a highly specialized differentiation process. The root meristem of Arabidopsis...
Plant vascular development
Vascular tissues in plants are crucial to provide physical support and to transport water, sugars and hormones and other small signalling molecules throughout the plant. Recent genetic and molecular studies have identified...

Plant Vasculature
To introduce pits into a cell wall, plants depolymerize cortical microtubules, which prevents subsequent secondary cell wall thickening. A newly identified protein tethers microtubules to the plasma membrane and contains this...
Genetic Networks in Plant Vascular Development.
Understanding the development of vascular tissues in plants is crucial because the evolution of vasculature enabled plants to thrive on land. Various systems and approaches have been used to advance our knowledge about the...
