Apomixis, asexual reproduction through seed, enables breeders to identify and faithfully propagate superior heterozygous genotypes by seed without the disadvantages of vegetative propagation or expense complexity hybrid production. The availability new tools such as genotyping sequencing bioinformatics pipelines for species lacking reference genomes now makes construction dense maps possible in apomictic species, despite complications including polyploidy, multisomic inheritance,...
Adaptation to replicate environments is often achieved through similar phenotypic solutions. Whether selection also produces convergent genomic changes in these situations remains largely unknown. The variable groundsel, Senecio lautus, an excellent system investigate the genetic underpinnings of evolution, because morphologically forms plants have adapted same along coast Australia. We compared range-wide patterns divergence natural populations this plant and searched for regions putatively...
The independent and repeated adaptation of populations to similar environments often results in the evolution forms. This phenomenon creates a strong correlation between phenotype environment is referred as parallel evolution. However, we are still largely unaware dynamics evolution, well interplay genotype within natural systems. Here, examined phenotypic genotypic multiple parapatric Dune-Headland coastal ecotypes an Australian wildflower, Senecio lautus. We observed clear...
The Catharanthus roseus plant is the exclusive source of valuable anticancer terpenoid indole alkaloids, vinblastine (VB) and vincristine (VC). recent availability transcriptome genome resources for C. necessitates a fast reliable method studying gene function. In this study, we developed an Agrobacterium-mediated transient expression to enable functional study genes rapidly in planta, conserving compartmentalization observed VB VC pathway. We focused on 1) improving transformation (syringe...
Abstract Background Bacterial leaf blight causes significant yield losses in rice crops throughout Asia and Africa. Although both the Asian African strains of pathogen, Xanthomonas oryzae pv. ( Xoo ), induce similar symptoms, they are nevertheless genetically different, with being more closely related to X. oryzicola Xoc ). Results Changes gene expression strain MAI1 susceptible cultivar Nipponbare were profiled, using an SSH DNA microarray. Microarray hybridization was performed comparing...
Abstract Motivation: We developed a technique and tool for degenerate primer design based on multiple local alignments employing the MEME algorithm supported with electronic PCR. The objective is to find adequate primers starting from sequences poor global similarity. show an example of its application in our laboratory Brachiaria similarity ESTs related apomixis.
