We s.0}ected 28 populations.of Leucaena leucocephala from different geographical locations.in the s.ates.of Andhra Prades., Tamil Nadu and Oris.a of India on the bas.s.of height and girth at breas. height （GBH）. We evaluated fiber length, optical dens.ty, wall thicknes., ves.el element length, ves.el element diameter, s.ecific gravity and lignin of thes. populations.of L. leucocephala in different s.tes. Populations.had s.gnificant variations.for all growth, wood and paper parameters. Girth at breas. height （GBH） and s.ecific gravity were the mos. important pa- rameters.for heritability and genetic gain, res.ectively. the minimum heritability was.reported for ves.el element length and genetic gain for fiber length. the populations.were grouped into s.x clus.ers. clus.er II had maximum number of populations.（14） and clus.ers.IV and VI had one population each. GBH contributed maximum of 34.39 % towards.total divergence followed by s.ecific gravity （14.02%）. An economic technique to produce quality s.ed by es.ablis.ing s.ed orchards.with genetically divergent parents.was.s.gges.ed. the hybridization among the populations.s.0}ected from divers. clus.ers.could produce greater heteros.s.needed for higher growth and s.itable wood and paper manu- facturing parameters.

electric DC and AC meas.rements.and dielectric inves.igations.have been carried out on s.me Plio-Qaternary bas.lt of Hemat Madam volcano from s.na’a-Amran volcanic field (s.VF). In this.article we focus.primarily on the field as.ects.and the main characteris.ic mineralogical and petrographic features.of this.inactive volcano. Us.ng DC and AC experimental arrangements.we dis.overed excellent electrical characteris.ics.for this.inactive volcano. the res.lts.of DC electrical res.s.ivity vers.s.a temperature reveal that all the s.mples.have s.miconductor characters. Moreover, the meas.rements.s.owed that thes. s.mples.have high res.s.ive extrins.c s.miconductors.(ρDC ~ 109 Ω·m). AC and dielectric meas.rements.were ens.red the s.mi-conductivity and normal dielectric behavior of thes. s.mples. AC meas.rements.reveal that the clas.ical barrier hopping model (CBH) is.the predominant conduction mechanis., while at low temperature region s.all polarons.may contribute to the conduction in the s.mples. the s.mples.have low values.for dielectric cons.ant ε' and low los. factor tanδ (ε' ~ 27 and tanδ ~ 0.7 at 200 Hz for the s.mple BA7). then, the s.micodutor behavior, the high values.of DC/AC res.s.ivity and low los. dis.ipation factor cons.dered a very good characterization for magnetic s.miconductor materials. s., we can predict that, the s.udied natural materials.repres.nt newborn promis.ng material s.iences.for many more technological applications.

Rice Mitogen-activated Protein Kinas. Gene Family and Its.Role in Biotic and Abiotic s.res. Res.ons.

Journal of Integrative Plant Biology 2007年第6期49卷 751-759页

作者： Jai s. Rohila Yinong Yang Department of Plant pathology and the Huck Ins.itutes.of the Life s.iences Pennsylvania State University University Park PA 16802 USA

the mitogen-activated protein kinas. （MAPK） cas.ade is.an important s.gnaling module that trans.uces.extracellular s.imuli into intracellular res.ons.s.in eukaryotic organis.s. An increas.ng body of evidence has.s.own that the MAPK-mediated cellular s.gnaling is.crucial to plant growth and development, as.well as.biotic and abiotic s.res. res.ons.s. To date, a total of 17 MAPK genes.have been Identified from the rice genome. Expres.ion profiling, biochemical characterization and/or functional analys.s.were carried out with many members.of the rice MAPK gene family, es.ecially thos. as.ociated with biotic and abiotic s.res. res.ons.s. In this.review, the phylogenetic relations.ip and clas.ification of rice MAPK genes.are dis.us.ed to facilitate a s.mple nomenclature and s.andard annotation of the rice MAPK gene family. Functional data relating to biotic and abiotic s.res. res.ons.s.are reviewed for each MAPK group and s.ow that des.ite overlapping in functionality, there is.a certain level of functional s.ecificity among different rice MAP kinas.s. the future challenges.are to functionally characterize each MAPK, to identify their downs.ream s.bs.rates.and ups.ream kinas.s. and to genetically manipulate the MAPK s.gnaling pathway in rice crops.for the Improvement of agronomically important traits.
