In the present paper, phy.ical m.chanism.responsible for origin of stream.ise vortices in m.de A appeared in the threedim.nsional (3-D) wake transition of a square-section cy.0}der is investigated. Direct num.rical sim.lations at a Rey.olds num.er of 180 firstly.show that such stream.ise vorticity.is not originated from.lateral surfaces. Then through the analy.is of local flow field in the im.ediate neighborhood of rear surface, based on the theory.of vortex-induced vortex, a new phy.ical m.chanism.is identified. At first, the vertical vorticity.on rear surface is generated by.the intrinsic three-dim.nsional instability.with the sam. instability.wavelength of m.de A. Then the stream.ise vorticity.at a specific sign is induced by.such vertical vorticity. convected and concentrated in the shear lay.rs. Finally. stream.ise vortices are form.d and shed with alternatively.shedding spanwise vortices in the near wake. m.reover, the effect of induced spanwise vorticity.on original two-dim.nsional (2-D) spanwise vorticity.is also presented in detail.

Photoreceptor cry.tochrom.s (CRy.) m.diate blue-light regulation of plant growth and developm.nt. It has been reported that Arabidopsis CRy.and CRy. function by.phy.ically.interacting with at least 84 proteins, including transcription factors or co-factors, chrom.tin regulators, splicing factors, m.ssenger RNA m.thy.transferases, DNA repair proteins, E3 ubiquitin ligases, protein kinases and so on. Of these 84 proteins, 47 have been reported to exhibit altered binding affinity.to CRy. in response to blue light, and 41 have been shown to exhibit condensation to CRy.photobodies. The blue light-regulated com.osition or condensation of CRy.com.lexes results in changes of gene expression and developm.ntal program.. In this m.ni-review, we analy.ed recent studies of the photoregulatory.m.chanism. of Arabidopsis CRy.com.lexes and proposed the dual m.chanism. of action, including the “Lock-and-Key. and the “Liquid-Liquid Phase Separation (LLPS)” m.chanism.. The dual CRy.action m.chanism. explain, at least partially. the structural diversity.of CRy.interacting proteins and the functional diversity.of the CRy.photoreceptors.
