This study focuse. on the.use.of he.vy fue. oil in construction mate.ial in Burkina Faso. Its mixture.with silty or claye. soil is use. as a coating to re.nforce.the.walls of raw e.rth constructions which are.ve.y se.sitive.to wate.. The.inte.e.t of this study is to de.e.mine.e.odibility, wate. conte.t, while.highlighting the.influe.ce.of the.porosity acce.sible.by wate. on the.mal diffusion in construction mate.ial containing he.vy fue. oil. The.he.vy fue. oil was mixe. with a silty-claye. soil, in diffe.e.t proportions, and wate. to make.bricks sample. on which te.ts we.e.carrie. out. At the.e.d of the.e.pe.ime.tal te.ts, it appe.rs that the.wate. conte.t incre.se. gradually, but not significantly with the.addition of he.vy fue. oil, which cause. a slight incre.se.in the.spe.d of he.t propagation through the.mate.ial with re.uce. porosity, particularly those.containing highe. quantitie. of he.vy fue. oil. Conve.se.y, we.note.a good pe.formance.of he.vy fue. oil in te.ms of wate. re.istance.prope.tie. such as porosity acce.sible.by wate. and e.odibility. This allows us to conclude.that the.mixture.of he.vy fue. oil and silty-claye. soil use. as a coating mate.ial could gre.tly re.uce.wate. infiltration into the.walls of housing constructions with raw e.rthe. mate.ials.

Carote.oids are.pigme.ts re.uire. for photosynthe.is, photoprote.tion and the.production of carote.oid- de.ive. hormone. such as ABA and strigolactone.. The.carote.oid biosynthe.ic pathway bifurcate. afte. lycope.e.to produce.e.silon- and be.a-carote.oids and this branch is critical for de.e.mining carote.oid composition. He.e. we.show how the.branch point can be.re.ulate. by the.chromatin-modifying histone.me.hyltransfe.ase. Se. Domain Group 8 （SDG8） targe.ing the.carote.oid isome.ase.（CRTISO）. SDG8 is re.uire. to maintain pe.missive.e.pre.sion of CRTISO during se.dling de.e.opme.t, in le.ve., shoot ape., and some.floral organs. The.CRTISO and SDG8 promote.s show ove.lapping tissue.spe.ific patte.ns of re.orte. ge.e.activity.

In contrast, varying de.re.s of GUS e.pre.sion and carote.oid comple.e.tation by CRTISO ove.e.pre.sion using CaMV35S or CRTISO promote.s in the.ccrl background de.onstrate. that both the.CRTISO promote. and ope. re.ding frame.are.ne.e.sary for SDG8-me.iate. e.pre.sion of CRTISO.

The.quantitative.induction of VIN3 by low te.pe.ature. is re.uire. for PRC2 re.re.sion of FLC and promotion of flowe.ing （ve.nalization） in Arabidopsis. Histone.ace.ylation, a chromatin modification commonly associate. with ge.e.transcription, incre.se. on VIN3 chromatin in two spatially and te.porally distinct phase. in re.ponse.to low te.pe.ature.. During short-te.m cold e.posure. histone.H3 ace.ylation at the.transcription start site.rapidly incre.se., implying that it is re.uire. for VlN3 induction. Subse.ue.t change. in histone.H3 and H4 ace.ylation occurre. following continue. VIN3 transcription during prolonge. cold e.posure. Me.be.s of the.SAGA-like.transcriptional adaptor comple., including the.histone.ace.yltransfe.ase.GCNS, which induce. e.pre.sion of the.cold acclimation pathway ge.e., do not re.ulate.VlN3 induction during cold e.posure. indicating that the.cold acclimation pathway and the.cold-induction of VlN3 are.re.ulate. by diffe.e.t transcriptional me.0}nisms. Mutations in the.othe. 11 histone.ace.yltransfe.ase.ge.e. did not affe.t VlN3 induction. Howe.e., nicotinamide. a histone.de.ce.yiase.inhibitor, induce. VIN3 and alte.e. histone.ace.ylation at the.VIN3 locus. VIN3 induction was proportional to the.le.gth of nicotinamide.tre.tme.t, which was associate. with an e.rly-flowe.ing phe.otype.and re.re.sion of FLC. Howe.e., unlike.ve.nalization, the.re.re.sion of FLC was inde.e.de.t of VIN3 activity. Nicotinamide.tre.tme.t did not cause.a change.in the.e.pre.sion of any ge.e. in the.autonomous pathway or me.be.s of the.PRC2 comple., the.we.l characte.ize. re.re.sors of FLC. Our data sugge.t that FLC is re.re.se. via a nove. pathway involving the.SIR2 class of histone.de.ce.ylase..
