Wheat flours are used to produce bread, pasta, breakfast cereals, and biscuits; the various properties of these end-products are attributed to the gluten content, produced as seed storage proteins in the wheat endosperm. Thus, genes encoding gluten protein are major targets of wheat breeders aiming to improve the various properties of wheat flour. Here, we describe a novel compensating wheat-Th...

Isoenzyme variation of esterase, peroxidase and acid phosphatase was examined in individual plants from natural populations of A. cristatum, D. villosum and L. elongatum. Four indices of phenotypic similarity (SI, S, D, Ih) were calculated in an attempt to assess relationships among the taxa studied. All indices have their lowest estimates in the comparison between L. elongatum and D. villosum....

The abundance and distribution of nematodes in the soil is influenced by biotic and abiotic soil factors. A previous study based on soil samples collected over a large part of KwaZulu-Natal showed that numbers of Pratylenchus, Helicotylenchus and Paratrichodorus were inversely related to pH and positively related to iron levels in the soil. Weaker relationships occurred between both aluminium a...

The transcriptome of Thinopyrum elongatum under water deficit stress was analyzed using RNA-Seq technology. The results showed that genes involved in processes of amplification of stress signaling, reductions in oxidative damage, creation of protectants, and roots development were expressed differently, which played an important role in the response to water deficit. The Th. elongatum transcrip...

Lophopyrum elongatum is a highly salt-tolerant relative of wheat. A previous study showed that the abundance of a number of mRNA species is enhanced or reduced in the roots of the L. elongatum x Triticum aestivum amphiploid by salt stress. Eleven genes with enhanced expression in the roots of salt-stressed L. elongatum plants have been cloned as cDNAs. The clones were used as probes to characte...

Roseibacterium elongatum Suzuki et al. 2006 is a pink-pigmented and bacteriochlorophyll a-producing representative of the Roseobacter group within the alphaproteobacterial family Rhodobacteraceae. Representatives of the marine 'Roseobacter group' were found to be abundant in the ocean and play an important role in global and biogeochemical processes. In the present study we describe the feature...
