Th.ol-based.red.x post-translational mod.fications h.ve emerged.as important mech.nisms of signaling and.regulation in all organisms, and.th.ored.xin plays a key role by controlling th. th.ol-d.sulfid. status of target proteins. Recent red.x proteomic stud.es revealed.h.nd.ed. of proteins regulated.by glutath.o- nylation and.nitrosylation in th. unicellular green alga Ch.amyd.monas reinh.rd.ii, wh.le much.less is known about th. th.ored.xin interactome in th.s organism. By combining qualitative and.quantitative proteomic analyses, we h.ve compreh.nsively investigated.th. Ch.amyd.monas th.ored.xome and.1188 targets h.ve been id.ntified. Th.y participate in a wid. range of metabolic path.ays and.cellular pro- cesses. Th.s stud. broad.ns not only th. red.x regulation to new enzymes involved.in well-known th.ore- d.xin-regulated.metabolic path.ays but also sh.d. ligh. on cellular processes for wh.ch.d.ta supporting red.x regulation are scarce （aromatic amino acid.biosynth.sis, nuclear transport, etc）. Moreover, we ch.r- acterized.1052 th.ored.xin-d.pend.nt regulatory sites and.sh.wed.th.t th.se d.ta constitute a valuable resource for future functional stud.es in Ch.amyd.monas. By comparing th.s th.ored.xome with.proteomic d.ta for glutath.onylation and.nitrosylation at th. protein and.cysteine levels, th.s work confirms th. existence of a complex red.x regulation network in Ch.amyd.monas and.provid.s evid.nce of a tremend.us selectivity of red.x post-translational mod.fications for specific cysteine resid.es.

作者： B. K. Tiwari h. Tynsong M. M. Lynrah.E. Lapasam S. d.b d. Sh.rma d.partment of Environmental Stud.es North-Eastern Hill University Regional Centre National Afforestation and Eco-Development BoardNorth-Eastern Hill University

Most community forests in h.ll regions of north.ast Ind.a h.ve been managed.by trad.tional local institutions for centuries and.most of th.se institutions remain functional even tod.y. h.gh.r forest coverage on private and.community land. as compared.to government land.ind.cates th.t trad.tional institutions effectively manage community forests in th. region. Th. present stud. was cond.cted.th.ough.a survey of literature and.field.work using participatory research.tools viz., PRA exercises, group d.scussions and.questionnaire interviews with.key informants in north.ast Ind.a. We categorized.th. institutions involved.in conservation and.management of forests into th.ee major types： trad.tional, quasi-trad.tional and.mod.rn. Trad.tional institutions with.h.erarch.l structure were found.in all states and.are intact and.functional in th. state of Megh.laya. Quasi-trad.tional institutions, a blend.of trad.tional and.mod.rn institutions were prevalent in Nagaland.wh.le mod.rn institutions h.ve almost replaced.trad.tional institutions in Mizoram. We record.d.at least eleven types of community forests viz., group of village forest, village forest, restricted.forest, sacred.forest, clan forest, cemetery forest, regeneration forest, bamboo forest, recreation forest, village reserved.forest and.med.cinal plantation in villages of th.ee states. Th. tribal people, th.ough.long-term trial and.error experiments, h.ve d.veloped.an elaborate, functional and.generally d.mocratic system of conservation and.management of forests and.associated.natural ecosystems. Several forest and.natural resource management lessons can be learnt from th. institutional structure and.d.cision making system of th. evolving and.d.namic institutions of tribal communities of th. region.

ULTIMET (R) alloy is a cobalt-based.superalloy th.t und.rgoes a d.formation-ind.ced.ph.se transformation from a face-centered.cubic (fcc) ph.se to a h.xagonal-close-packed.(h.p) ph.se. Th. transformation was stud.ed.d.ring monotonic load.ng, stress-controlled.h.gh.cycle fatigue (h.F) and.strain-controlled.low-cycle fatigue (LCF). Th. h.F was performed.at a maximum stress of sigma(max) =840 MPa and.a minimum stress of sigma(min) =84 MPa, wh.le th. tensile experiment was terminated.after reach.ng sigma(max) =890 MPa. Th. LCF was performed.at. a maximum strain of sigma(max) =1.25% and.a minimum strain Of sigma(min) =-1.25%. Th. monotonic-load.ng experiment results reveal th.t th. h.p ph.se forms after reach.ng th. yield.stress. d.ring h.F, th. h.xagonal ph.se forms immed.ately upon th. first fatigue cycle, with.no furth.r ch.nge in structure upon subsequent d.formation. In contrast to h.F, th. h.p ph.se forms grad.ally d.ring LCF. In fact, fatigue cycle 12 is reach.d.before th. h.p ph.se is resolved.by neutron d.ffraction. d.ffraction patterns from subsequent fatigue cycles reveal th.t th. h.p ph.se continues to accumulate as LCF progresses. Th.se observations can be related.to th. input of mech.nical energy d.ring d.fferent load.ng mod.s.

Th. time-d.pend.nt wave-packet meth.d.was employed.to calculate th. first full-d.mensional state-to-state d.fferential cross sections （d.S） for th. title reaction with.d.O in th. ground.and.th. first symmetric （100） and.asymmetric stretch.ng （001） excited.states. Th. calculated.d.Ss for th.se th.ee initial states are strongly backward.peaked.at low collision energies. With.th. increase of collision energy, th.se d.Ss become increasingly broad.r with.th. peak position sh.fting grad.ally to a smaller angle, consistent with.th. fact th.t th. title reaction is a d.rect reaction via an abstraction mech.nism. It is found.th.t th. （100） and.（001） states not only h.ve rough.y th. same integral cross sections, but also h.ve essentially id.ntical d.S, wh.ch.are very close to th.t for th. ground.state at th. same total energy of reaction. Th. reaction prod.ces a small fraction of Od.in th. v=1 state, with.th. population close to th. relative reactivity between th. ground.and.vibrationally excited.states, th.refore confirming th. experimental result of Zare et al. and.th. local mod. picture [J. Ph.s. Ch.m. 97, 2204 （1993）]. Unexpected.y, th. stretch.ng excitation red.ces th. rotation excitation of prod.ct h. at th. same total energy.

A biologically active antibacterial reagent, 2-amino-6-h.d.oxy-4-（4-N, N-d.meth.laminoph.nyl）-pyr- imid.ne-5-carbonitrile （Ah.MAPPC）, was synth.sized. It was employed.to investigate th. bind.ng in- teraction with.th. bovine serum albumin （BSA） in d.tail using d.fferent spectroscopic meth.d.. It ex- h.bited.antibacterial activity against Esch.rich.a cali and.Staph.lococcus aureus wh.ch.are common food.poisoning bacteria. Th. experimental results sh.wed.th.t th. fluorescence quench.ng of mod.l carrier protein BSA by Ah.MAPPC was d.e to static quench.ng. Th. site bind.ng constants and.number of bind.ng sites （n ≈ 1） were d.termined.at th.ee d.fferent temperatures based.on fluorescence quench.ng results. Th. th.rmod.namic parameters, enth.lpy ch.nge （Ah., free energy （AG） and.entropy ch.nge （AS） for th. reaction were calculated.to be 15.15 kJ/mol, -36.11 kJ/mol and.51.26J/mol K accord.ng to van＇t h.ff equation, respectively. Th. results ind.cated.th.t th. reaction was an end.th.rmic and.spontaneous process, and.h.d.oph.bic interactions played.a major role in th. bind.ng between d.ug and.BSA. Th. d.stance between d.nor and.acceptor is 2.79 nm accord.ng to Forster＇s th.ory. Th. alterations of th. BSA second.ry structure in th. presence of Ah.MAPPC were confirmed.by UV-visible, synch.onous fluorescence, circular d.ch.oism （Cd. and.th.ee-d.mensional fluorescence spectra. All th.se results in- d.cated.th.t Ah.MAPPC can bind.to BSA and.be effectively transported.and.eliminated.in th. bod.. It can be a useful guid.line for furth.r d.ug d.sign.
