Miniature inverted-repeat transposable elements (MITEs) are expected to play important roles in evolution of genes and genome in plants, especially in the highly duplicated plant genomes.
Thus, CNV is likely to contribute to quantitative variation rather than qualitative defects in the complex and highly duplicated plant genome [ 30].
The deepest dichotomy shown in Figure 5 separates a group formed by several animal cullin genes (Cul1, Cul2, Cul5, Cul-Dros, Cul7/Parc) a single fungal cullin gene (Cul1, also known as Cdc53) and two recently duplicated plant cullin genes (Cul1 and Cul2) from two other groups which respectively include the cullin genes so far named Cul3 and Cul4 in animals, plants and fungi.
Duplicate plants were removed from hydroponic culture at different time points and roots were treated with hydrogen peroxide (15%, 10 min) to sterilize the root surface.
Indeed, further comparative functional analyses of such single-copy genes could be used to test whether natural selection culls duplicates from plant genomes following segmental or genome-wide duplication events.
Previous studies showed that structural divergences have played important role during the evolution of duplicates in plants [ 34, 35].
To test the hypothesis that pI changes occur in relocalized duplicates in plants, we estimated the pI difference (ΔpI) between duplicated pairs.
The goal of this study was to understand the frequency, causes, and effects of reciprocal expression patterns of WG duplicates and tandem duplicates in a plant in a broad range of developmental stages, organ types, and cell types.
The leaves were carefully seperated from the plant, duplicate samples prepared and authenticated by a botanist at the National Museums Herbarium.
I confirmed the presence of tandemly repeated Ariadnes (of both groups, A and B) in Arabidopsis, as first described in [16], and also found multiple tandem duplicates in the Plant II A group in that same species (Figure 4).
