Linear I-V for bare silver nanowire suggests metallic behavior but high tunnel resistance indicates presence of insulating layer on the surface. Identical I-Vs obtained for isolated gold nanoparticle and heterostructure suggests that electron transport across nanowires in the latter is governed by gold nanoparticles in contrast to expected ballistic or diffusive transport along their length.(c) 2006 American Institute of Physics.</p>1 aSharma, J.1 aVivek, J., P.1 aVijayamohanan, K., P.1 aSingh, P.1 aDharmadhikari, C., V.  uhttps://library.ncl.res.in/content/directed-organization-gold-nanoclusters-silver-nanowires-step-forward-heterostructure-101988nas a2200349   4500008004100000022001400041245009800055210006900153260008900222300001200311490000800323520087500331100001401206700001501220700001601235700002001251700001501271700002401286700002001310700001401330700002101344700001601365700001601381700001301397700001601410700001401426700001701440700001901457700002001476700001901496856012301515       2013                        eng d  a0036-807500aBiosynthesis of antinutritional alkaloids in solanaceous crops is mediated by clustered genes0 aBiosynthesis of antinutritional alkaloids in solanaceous crops i  a1200 NEW YORK AVE, NW, WASHINGTON, DC 20005 USAbAMER ASSOC ADVANCEMENT SCIENCEcJUL  a175-1790 v3413 a<p>Steroidal glycoalkaloids (SGAs) such as alpha-solanine found in solanaceous food plants-as, for example, potato-are antinutritional factors for humans. Comparative coexpression analysis between tomato and potato coupled with chemical profiling revealed an array of 10 genes that partake in SGA biosynthesis. We discovered that six of them exist as a cluster on chromosome 7, whereas an additional two are adjacent in a duplicated genomic region on chromosome 12. Following systematic functional analysis, we suggest a revised SGA biosynthetic pathway starting from cholesterol up to the tetrasaccharide moiety linked to the tomato SGA aglycone. Silencing GLYCOALKALOID METABOLISM 4 prevented accumulation of SGAs in potato tubers and tomato fruit. This may provide a means for removal of unsafe, antinutritional substances present in these widely used food crops.</p>1 aItkin, M.1 aHeinig, U.1 aTzfadia, O.1 aBhide, Amey, J.1 aShinde, B.1 aCardenas, Pablo, D.1 aBocobza, S., E.1 aUnger, T.1 aMalitsky, Sergey1 aFinkers, R.1 aTikunov, Y.1 aBovy, A.1 aChikate, Y.1 aSingh, P.1 aRogachev, I.1 aBeekwilder, J.1 aGiri, Ashok, P.1 aAharoni, Asaph  uhttps://library.ncl.res.in/content/biosynthesis-antinutritional-alkaloids-solanaceous-crops-mediated-clustered-genes-0
