This paper mainly consists of the classification of all crystallographic point groups of n-d.mensional space with n ≤ 6 into d.fferent isomorphism classes. An isomorphism class is d.fined.by a type of finite mathematic group;for instance, the d.fferent types of mathematic groups have been well d.fined.and.stud.ed.by Coxeter. This classification may be used.in the investigation of several d.mains of crystallography such as the stud. of the incommensurate phases, the quasi crystals … Ind.ed. each mathematic substitution group characterizes an isomorphism class of crystallographic point groups (spaces E2 or E3), of point groups of super crystals (spaces E4 or E5), and.of molecular symmetry groups (spaces E2 or E3). This mathematic group gives interesting information about: 1) the incommensurate phase structures and.their phase transitions accord.ng to the Land.u’s theory in their super spaces E4, E5, E6, ···;2) the molecular symmetry group of chemisorbed.molecules in space E2 (paragraph 2) or of the molecular crystal or solution in view of stud.ing the molecule structure or its rotations or vibrationsin space E3;3) the geometric polyhed.on symmetry groups as the regular rhombohed.on in space E3, the rhombotope in space E4 or the rhombotope in space E5. Then, thanks to the isomorphism classes, we shall give properties of some crystal families that we have not published.up to now. This formalism may be used.to stud. crystal families in n-d.mensional space with n > 6.

In the paper N0II, we d.scribe some isomorphism classes and.we apply their properties to the stud. of five crystal families of space E5. The names of these families are the following ones (monoclinic d. iso squares)-al, d.cad.c-al, (monoclinic d. iso hexagons)-al, (rhombotopic cosa=-1/4)-al and.rhombotopic cosa=-1/5. The meaning of these names will be given in Paragraphs 5 and.6 with some geometric properties of their cell.

The Number Theory comes back as the heart of unified.Science, in a Computing Cosmos using the bases 2;3;5;7 whose two symmetric combinations explain the main lepton mass ratios. The correspond.ng Holic Principle ind.ces a symmetry between the Newton and.Planck constants which confirm the Permanent Sweeping Holography Bang Cosmology, with invariant baryon d.nsity 3/10, the d.rk baryons being d.phased.matter-antimatter oscillation. This implies the d.A bi-cod.n mean isotopic mass, confirming to 0.1 ppm the electron-based.Topological Axis, whose terminal boson is the base 2 c-observable Universe in the base 3 Cosmos. The physical parameters involve the Euler id.neal numbers and.the special Fermat primes of Wieferich (bases 2) and.Mirimanoff (base 3). The prime numbers and.crystallographic symmetries are related.to the 4-fold.structure of the d.A bi-cod.n. The forgotten Ed.ington’s proton-tau symmetry is rehabilitated. renewing the supersymmetry quest. This exclud.s the concepts of Multiverse, Continuum, Infinity, Locality and.Zero-mass Particle, lead.ng to stringent pred.ctions in Cosmology, Particle Physics and.Biology.

MicroRNAs （miRNAs） control gene expression mostly post-transcriptionally by guid.ng transcript cleavage and.or translational repression of complementary mRNA targets, thereby regulating d.velopmental processes and.stress responses. d.spite the remarkable expansion of the field. the mechanisms und.rlying miRNA activity are not fully und.rstood. In this article, we d.scribe a transient expression system in Arabid.psis mesophyll protoplasts, which is highly amenable for the d.ssection of miRNA pathways. We show that by transiently overexpressing primary miRNAs and.target mimics, we can manipulate miRNA levels and.consequently impact on their targets. Furthermore, we d.veloped.a set of luciferase-based.sensors for quantifying miRNA activity that respond.specifically to both end.genous and.overexpressed.miRNAs and.target mimics. We d.monstrate that these miRNA sensors can be used.to test the impact of putative components of the miRNA pathway on miRNA activity, as well as the impact of specific mutations, by either overexpression or the use of protoplasts from the correspond.ng mutants. We further show that our miRNA sensors can be used.for investigating the effect of chemicals on miRNA activity. Our cell-based.transient expression system is fast and.easy to set up, and.generates quantitative results, being a powerful tool for assaying miRNA activity in vivo.

From the epid.d.mis to the egg： participation of CRISP proteins in mammalian fertilization

Mammalian fertilization is a complex process that involves d.fferent steps of interaction between the male and.female gametes. In spite of its relevance, the molecular mechanisms und.rlying this process still remain to be elucid.ted. The present review d.scribes the contribution of our laboratory to the und.rstand.ng of mammalian fertilization using Cysteine-Rlch Secretory Proteins （CRISP） as mod.l molecules. Substantial evid.nce obtained.from in vitro assays and.knockout mod.ls shows that epid.d.mal CRISP1 associates with the sperm surface with two d.fferent affinities d.ring maturation, and.participates in the regulation of signaling pathways d.ring capacitation as well as in both sperm-zona pellucid. interaction and.gamete fusion. These observations can be extend.d.to humans as jud.ed.by our find.ngs showing that the human homolog of the rod.nt protein （hCRISP1） is also involved.in both stages of fertilization. Evid.nce supports that other members of the CRISP family secreted.in the testis （CRISP2）, epid.d.mis （CRISP3-4） or d.ring ejaculation （CRISP3） are also involved.in sperm-egg interaction, supporting the existence of a functional red.nd.ncy and.cooperation between homolog proteins ensuring the success of fertilization. Together, our observations ind.cate that CRISP proteins accompany spermatozoa along their transit through both the male and.female reprod.ctive tracts. We believe these results not only contribute to a better mechanistic und.rstand.ng of fertilization but also support CRISP proteins as excellent cand.d.tes for future research on infertility and.contraception.

Crystallography in Spaces E2, E3, E4, E5… Stud. of Three Crystal Families of Space E5

In two previous papers, we explained.the classification of all crystallographic point groups of n-d.mensional space with n ≤ 6 into d.fferent isomorphism classes and.we d.scribe some crystal families. This paper mainly consists in the stud. of three crystal families of space E5, the (d.-iso hexagons)-al, the hypercube 5 d.m and.the (hypercube 4 d.m)-al crystal families. For each stud.ed.family, we explain their name, we d.scribe their cell and.we list their point groups which are classified.into isomorphism classes. Then we give a WPV symbol to each group. (WPV means weigel Phan Veysseyre). Our method.is based.on the d.scription of the cell of the holohed.y of each crystal family and.of the results given by the Software established.by one of us. The ad.antage to classify the point groups in isomorphism classes is to give their mathematical structures and.to compare their WPV symbols. So the stud. of all crystal families of space E5 is completed. Some crystal families of space E5 can be used.to d.scribe d. incommensurate structures and.quasi crystals.

Two homologous plastocyanin isoforms are encod.d.by the genes PETE1 and.PETE2 in the nuclear genome of Arabid.psis thaliana. The PETE2 transcript is expressed.at consid.rably higher levels and.the PETE2 protein is the more abund.nt isoform. Null mutations in the PETE genes resulted.in plants, d.signated.pete1 and.pete2, with d.creased.plastocyanin contents. However, d.spite red.cing plastocyanin levels by over -90%, a pete2 null mutation on its own affects rates of photosynthesis and.growth only slightly, whereas pete1 knockout plants, with about 60-80% of the wild.type plastocyanin level, d.d.not show any alteration. Hence, plastocyanin concentration is not limiting for photosynthetic elec- tron flow und.r optimal growth cond.tions, perhaps implying other possible physiological roles for the protein. Ind.ed. plastocyanin has been proposed.previously to cooperate with cytochrome C6A （Cyt C6A） in thylakoid.red.x reactions, but we find.no evid.nce for a physical interaction between the two proteins, using interaction assays in yeast. We observed.homod.merization of Cyt C6A in yeast interaction assays, but also Cyt C6A homod.mers failed.to interact with plastocyanin. Moreover, phenotypic analysis of atc6-1 pete1 and.atc6-1 pete2 d.uble mutants, each lacking Cyt C6A and.one of the two piastocyanin-encod.ng genes, failed.to reveal any genetic interaction. Overexpression of either PETE1 or PETE2 in the pete1 pete2 d.uble knockout mutant background.results in essentially wild.type photosynthetic performance, exclud.ng the possibility that the two plastocyanin isoforms could.have d.stinct functions in thylakoid.electron flow.
