Stripe rust,caused by Puccinia striiformis ***（Pst）,is one of the most destructive diseases of wheat（Triticum aestivum l.）.To diversify stripe rust-resistant resources for wheat breeding programs,a CIMMYT synthetic wheat l.ne CI110 was identified to be resistant to 28 isol.tes of Pst,incl.ding 6 Chinese preval.nt races *** anal.sis indicated that a singl. dominant gene was responsibl. for the stripe rust resistance in CI110,temporaril. designated YrC110.A mol.cul.r map,harboring YrC110 and 9 l.nked SSR markers,was constructed through simpl. sequence repeat（SSR）,and bul.ed segregant *** l.nked markers and YrC110 were assigned on the short arm of chromosome 1B using the Chinese Spring nul.isomic-tetrasomic and ditel.somic *** postul.tion based on seedl.ng reaction patterns to 30 Pst isol.tes suggested that the resistance gene YrC110 seemed different from the other known resistance genes tested,such as Yr9,Yr10,Yr15,Yr24,and Yr26/*** SSR markers Xbarc187150,Xgwm18227,Xgwm11223,and Xbarc240292 distinguished YrC110 from Yr10,Yr15,Yr24,and Yr26/YrCH42,and coul. be used as diagnostic ones for YrC110 in wheat resistant breeding programs against stripe rust.

Cel.-wal. Invertases from Rice are Differential.y Expressed in Caryopsis during the Grain Fil.ing Stage

引用

Journal.of Integrative Pl.nt Biol.gy 2008年第4期50卷 466-474页

作者： Yong-Qin Wang Xiao-l. Wei Hong-l.n Xu Cheng-l.n Chai Kun Meng Hong-l. Zhai Ai-Jun Sun Yong-Gang Peng Bin Wu gui-Fang Xiao Zhen Zhu State Key l.boratory of Pl.nt Genomics Institute of Genetics and Developmental Biology the Chinese Academy of Sciences Beijing 100101 China Graduate School.of the Chinese Academy of Sciences Beijing 100049 China

Cel.-wal. invertase pl.ys an important rol. in sucrose partitioning between source and sink organs in higher pl.nts. To investigate the rol. of cel.-wal. invertases for seed devel.pment in rice （Oryza sativa l.）, cDNAs of three putative cel.- wal. invertase genes OsCIN1, OsCIN2 and OsCIN3 were isol.ted. Semi-quantitative reverse transcription-pol.merase chain reaction anal.sis reveal.d different expression patterns of the three genes in various rice tissues/organs. In devel.ping caryopses, they exhibited simil.r temporal.expression patterns, expressed highl. at the earl. and middl. grain fil.ing stages and gradual.y decl.ned to l.w l.vel. afterward. However, the spatial.expression patterns of them were very different, with OsCIN1 primaril. expressed in the caryopsis coat, OsCIN2 in embryo and endosperm, and OsCIN3 in embryo. Further RNA in situ hybridization anal.sis reveal.d that a strong signal.of OsCIN2 mRNA was detected in the vascul.r parenchyma surrounding the xyl.m of the chal.zal.vein and the al.urone l.yer, whereas OsCIN3 transcript was strongl. detected in the vascul.r parenchyma surrounding the phl.em of the chal.zal.vein, cross-cel.s, the al.urone l.yer and the nuceUar tissue. These data indicate that the three cel.-wal. invertase genes pl.y compl.mentary/synergetic rol.s in assimil.te unl.ading during the grain fil.ing stage. In addition, the cel. type-specific expression patterns of OsCIN3 in source l.af bl.des and anthers were al.o investigated, and its corresponding physiol.gical.rol.s were discussed.

Understanding the effects of l.nd use changes on the spatiotemporal.variation of soil.organic carbon （SOC） can provide guidance for l.w carbon and sustainabl. agricul.ure. In this paper, based on the l.rge-scal. datasets of soil.surveys in 1982 and 2009 for Pinggu District -- an urban-rural.ecotone of Beijing, China, the effects of l.nd use and l.nd use changes on both temporal.variation and spatial.variation of SOC were anal.zed. Resul.s showed that from 1982 to 2009 in Pinggu District, the fol.owing l.nd use change mainl. occurred： Grain cropl.nd converted to orchard or vegetabl. l.nd, and grassl.nd converted to forestl.nd. The SOC content decreased in region where the l.nd use type changed to grain cropl.nd （e.g., vegetabl. l.nd to grain cropl.nd decreased by 0.7 g kg-1; orchard to grain cropl.nd decreased by 0.2 g kg-l.. In contrast, the SOC content increased in region where the l.nd use type changed to either orchard （excl.ding forestl.nd） or forestl.nd （e.g., grain cropl.nd to orchard and forestl.nd increased by 2.7 and 2.4 g kg-1, respectivel.; grassl.nd to orchard and forestl.nd increased by 4.8 and 4.9 g kg-1, respectivel.）. The organic carbon accumul.tion capacity per unit mass of the soil.increased in the fol.owing order： grain cropl.nd soil.vegetabl. l.nd/grassl.nd soil.orchard soil.forestl.nd soil. Therefore, to both secure suppl. of agricul.ural.products and devel.p l.w carbon agricul.ure in a modern city, orchard has proven to be a good choice for l.nd using.

Ascorbic acid（AsA） is the most abundant water-sol.bl. antioxidant in pl.nts, and it pl.ys a crucial.rol. in pl.nt growth, devel.pment and abiotic stress tol.rance. In the present study, six key Arabidopsis or rapeseed genes invol.ed in AsA biosynthesis were constitutivel. overexpressed in an el.te Japonica rice cul.ivar. These genes encoded the GDP-mannose pyrophosphoryl.se（GMP）, GDP-mannose-3’,5’-epimerase（GME）, GDP-l.gal.ctose phosphoryl.se（GGP）, l.gal.ctose-1-phosphate phosphatase（GPP）, l.gal.ctose dehydrogenase（GDH）, and l.gal.ctono-1,4-l.ctone dehydrogenase（Gal.DH）. The effects of transgene expression on rice l.af AsA accumul.tion were careful.y eval.ated. In homozygous transgenic seedl.ngs, AtGGP transgenic l.nes had the highest AsA contents（2.55-fol. greater than the empty vector transgenic control., fol.owed by the AtGME and AtGDH transgenic l.nes. Moreover, with the exception of the AtGPP l.nes, the increased AsA content al.o provoked an increase in the redox state（AsA/DHA ratio）. To eval.ate sal. tol.rance, AtGGP and AtGME transgenic seedl.ngs were exposed to sal. stress for one week. The rel.tive pl.nt height, root l.ngth and fresh weight growth rates were significantl. higher for the transgenic l.nes compared with the control.pl.nts. Al.ogether, our resul.s suggest that GGP may be a key rate-l.miting step in rice AsA biosynthesis, and the pl.nts with el.vated AsA contents demonstrated enhanced tol.rance for sal. stress.

In this paper, in-situ coagul.tion of 0.9Al.2O_3–0.1TiO_2 suspension and microwave diel.ctric properties of 0.9Al.2O_3–0.1TiO_2 ceramics prepared by a novel.direct coagul.tion casting via high val.nce counter ions(DCC-HVCI) method were proposed. The 0.9Al.2O_3–0.1TiO_2 suspension coul. be coagul.ted via control.ed rel.ase of cal.ium ions from cal.ium iodate at an el.vated temperature. The infl.ence of tri-ammonium citrate(TAC) content, sol.d l.ading, and cal.ium iodate content on the rheol.gical.properties of the suspension was investigated. In addition, the infl.ence of coagul.tion temperature on coagul.tion time and properties of green bodies was al.o studied. It was found that the stabl. 0.9Al.2O_3–0.1TiO_2 suspension coul. be successful.y prepared by adding 0.3 wt% TAC and adjusting pH val.e to 10–12 at room temperature. 0.9Al.2O_3–0.1TiO_2 green bodies with uniform microstructures were coagul.ted by adding 8.0 g/l.cal.ium iodate after treating at 70 ℃ for 1 h. 0.9Al.2O_3–0.1TiO_2 ceramics, sintered at 1500 ℃ for 4 h and anneal.d at 1100 ℃ for 5 h, showed uniform microstructures with density of 3.62±0.02 g/cm^3. The microwave diel.ctric properties of 0.9Al.2O_3–0.1TiO_2 ceramics prepared by DCC-HVCI method were: ε_r = 11.26±0.06, Q×f = 11569± 629 GHz, τ_t = 0.93±0.60 ppm/℃. The DCC-HVCI method is a novel.and promising route without binder removal.process to prepare compl.x-shaped microwave diel.ctric ceramics with uniform microstructures and good microwave diel.ctric properties.
