Structural characterization of the members of a polymer series, compatible solutes in Anabaena cells exposed to salt stress

Horacio G. Pontis, Walter A. Vargas, Graciela L. Salerno

Plant Science > 2007 > 172 > 1 > 29-35

In response to salinity cyanobacteria synthesize different osmoprotective compounds. We had reported that Anabaena cells accumulate not only sucrose (Suc) but also fructose-containing oligosaccharides in the presence of NaCl and at stationary phase (Plant Sci. 167 (2004) 1003–1008). In the present study, using NMR and GC–MS we showed that the oligosaccharides previously described are members of a...

Functional characterization of a small auxin-up RNA gene in apical hook development in Arabidopsis

Jung-Eun Park, Youn-Sung Kim, Hae-Kyung Yoon, Chung-Mo Park

Plant Science > 2007 > 172 > 1 > 150-157

Auxin functions, at least in part, by regulating a set of early auxin response genes: Aux/IAAs, GH3s and small auxin-up RNAs (SAURs). The SAUR genes encode short transcripts that accumulate rapidly after auxin treatment. There are 72 SAUR genes in Arabidopsis. However, none of these genes have been functionally characterized, although some members have been implicated in calcium/calmodulin-mediated...

Clementine Vitte, Cristian Chaparro, Hadi Quesneville, Olivier Panaud

Plant Science > 2007 > 172 > 1 > 8-19

Transposable elements are the main components of complex genomes. Their impact on the genomes in terms of structural changes during evolution is thus one of the main focuses of today's structural genomics. Although non-autonomous transposable elements have been known for a long time, their contribution to genome evolution is poorly understood. Our present study describes two new non-autonomous LTR...
