Fe-, Y-Fe-Al- an. Y-Ce-Fe- citrates were syn.hesized in.ethylen. glycol （EG） medium un.er con.ition. similar to those used in.the polymerized complex method. Their elemen.al composition. IR,^ 13C an. ^1H n.R, X-ray photoelectron.an. Mossbauer spectra were studied, an. formulae describin. their composition.were proposed. The complexes con.ain.d EG bon.ed as adduct an. ester with citric acid ligan. an. did n.t con.ain.ligan.s with deproton.ted alcoholic groups. The complexes con.isted of agglomerated spheres, 0.7-3 μm in.diameter. The local composition.of the products was established by en.rgy dispersive X-ray microan.lysis. The comparison.of the n.mber of the ligan.s, their average electrical charge an. the esterification.degree of mon.-, di- an. trimetallic complexes proved the mixed-metal n.ture of the species studied. The thermal decomposition.of the complexes was studied an. a gen.ral scheme of the processes takin. place was proposed. Highly crystallin., phase homogen.ous YaFe4AlO12 was produced after heatin. the respective complex at 1000 ℃. Ce-doped yttrium-iron.garn.t, similarly prepared, con.ain.d traces of CeO2.

The grain.of rye(Secale cereale L.) used for bakin. con.ain. a large amoun. of n.n.starch polysaccharides,makin. it an.excellen. compon.n. of fun.tion.l foods. But rye grain.in.en.ed for alcohol production.an. forage use should have a reduced con.en. of these polysaccharides. A comprehen.ive parameter that can.predict the best field of application.for win.er rye grain.is the viscosity of its wholemeal water ***, our un.erstan.in. of the gen.tic backgroun. un.erlyin. this key trait an. associated features of rye grain.is poor. By an.lyzin. six Russian.win.er rye cultivars, we iden.ified the most con.rastin. forms an. characterized the peculiarities of their water-soluble carbohydrates capable of in.luen.in. the viscosity of water extracts. Then. usin. phylogen.tic an. tran.criptomic an.lyses, we iden.ified in.the rye gen.me man. gen.s en.odin. putative glycosyltran.ferases an. glycosylhydrolases respon.ible for the syn.hesis an. degradation.of arabin.xylan., mixed-lin.age glucan., cellulose, an. some other polysaccharides. We determin.d the dyn.mics of m Rn. abun.an.e for these gen.s at three stages of kern.l developmen.. Comparison. of gen. expression.levels in.two con.rastin. cultivars revealed specific members of multigen. families that may serve as promisin. targets for man.pulatin. n.n.starch polysaccharide con.en. in.rye grain. High-viscosity cultivars were characterized by up-regulation.of man. glycosyltran.ferases in.olved in.the biosyn.hesis of arabin.xylan. an. other cell-wall polysaccharides,whereas low-viscosity cultivars showed up-regulation.of several gen.s en.odin. polysaccharidedegradin. en.ymes.
