“…The other cytoplasmic type is found in T. aestivum (AABBDD), T. turgidum (AABB), T. timopheevi (AAGG) and only two species of the Sitopsis section, T. speltoïdes and T. aucheri. This finding is consistent with the hypothesis on the origin of the cultivated wheats where the cytoplasmic and B genome donor of AB and ABD wheats is closer to T. speltoïdes and T. aucheri than to any other Sitopsis species [43].…”

Proteomics for genetic and physiological studies in plants

Proteomics is becoming a necessity in plant biology, as it is in medicine, zoology and microbiology, for deciphering the function and role of the genes that are or will be sequenced. In this review we focus on the various, mainly genetic, applications of the proteomic tools that have been developed in recent years: characterization of individuals or lines, estimation of genetic variability within and between populations, establishment of genetic distances that can be used in phylogenetic studies, characterization of mutants and localization of the genes encoding the revealed proteins. Improvements in specifically devoted software have permitted precise quantification of the variation in amounts of proteins, leading to the concept of “protein quantity loci” which, combined with the “quantitative trait loci” approach, results in testable hypotheses regarding the role of “candidate proteins” in the metabolism or phenotype under study. This new development is exemplified by the reaction of plants to drought, a trait of major agronomic interest. The accumulation of data regarding genomic and cDNA sequencing will be connected to the protein databases currently developed in plants.

“…Comparison of alloplasmic lines (the same nuclear genome introduced by backcrosses in different cytoplasms) led to the detection of three cytoplasmically encoded proteins [43]: the large subunit of Rubisco and two forms of the beta subunit of chloroplast ATPsynthase, i.e. three products of two chloroplast genes.…”

“…The data obtained on the cytoplasmically encoded proteins were non ambiguous: only T speltoides and T aucheri have the polyploid AABB, AAGG and AABBDD cytoplasmic type (Bahrman et al, 1988). The analysis reported here on more than a thousand gene products, whereas leading to the same conclusion, is less clear cut.…”

“…Among the 14 spots present only in CS and in speltoides-aucheri, at least three are cytoplasmically encoded, the large subunit of Rubisco and two other proteins that are likely two forms of the beta subunit of the chloroplastic ATP synthase (Bahrman et al 1988). Three other spots, specifically absent in CS and speltoides-aucheri, are the allelic forms of these same three chloroplastic gene products.…”

“…However the origin of the cytoplasm and of the B genome of Triticum turgidum and T aestivum is still a subject of active controversy. We recently took into consideration the variability of 3 cytoplasmically encoded proteins in the genus Triticum (Bahrman et al, 1988). According to these experiments only T speltoides and T aucheri, both from the Sitopsis section, have the same cytoplasmic type as T turgidum, T timopheevi and T aestivum.…”

Genetic relationships in the Sitopsis section of Triticum and the origin of the B genome of polyploid wheats

1988

The proteins extracted from etiolated seedlings of 10 accessions, representatives of the species of the Sitopsis section of Triticum were analyzed by two-dimensional (2D) gel electrophoresis. The 2D patterns were compared and similarity indices were computed between all accessions. From the similarity matrix a dendrogram was deduced, that gave interesting information concerning the genetic relationships between the species of the Sitopsis section. The 2D pattern obtained from the Chinese Spring variety of Triticum aestivum was then included in the analysis. From the dendrogram obtained and also from the number of species-specific proteins shared between Chinese Spring and each of the Sitopsis species, it is proposed that the B genome donor of the cultivated wheats originated from a species closer to the T. speltoides-T. aucheri group than to any other diploid Sitopsis species.

Comparative proteomics to establish genetic relationships in the Brassicaceae family

et al. 2001

The comparisons of the same proteome (aerial part of etiolated seedlings) in different species and genus of the plant family Brassicaceae (cabbages, mustards, rapes, radishes and Arabidopsis) was undertaken to establish genetic proximities between them. Genetic distances were calculated on the basis of common and distinct spots. The construction of phenetic trees and factorial correspondence analysis that were performed are in very good agreement with our actual knowledge of the taxonomy of the Brassicaceae. The position of the tetraploids, for instance, is in between the positions of their constitutive genome donor representatives. Comparative proteomics may be helpful to shorten the transfer between model and agronomic target species.
