EST-SSRs as a resource for population genetic analyses
It is concluded that half of all suitable EST databases could be exploited for the population genetic analysis of species of conservation concern and the advantages and disadvantages of EST-SSRs in the context of population genetic applications are discussed.

It is revealed that more than one-third of all plant-derived EST collections of sufficient size could conceivably serve as a source of EST-SSRs for the analysis of rare, endangered, or invasive plant species worldwide.

This study uses nuclear and chloroplast SSRs (simple sequence repeats) to investigate the population genetics of an extremely rare sunflower, Helianthus verticillatus Small, which is known from only three locations in North America and concludes that it is not of hybrid origin.
Chloroplast Division and DNA Synthesis in Light-grown Wheat Leaves.
Light-grown 7-day-old wheat seedlings (Triticum aestivum, var. Maris Dove) showed an increase of 200% in plastids per cell between 1.7 and 4.5 centimeters from the leaf base, and [(3)H]Thymidine was incorporated into plastid DNA throughout the zone ofplastid division, but not above it.
Cell size and chloroplast size in relation to chloroplast replication in light-grown wheat leaves
The results indicate that the proportion of the cell surface area covered by chloroplast is precisely regulated, and that this is achieved during cell development by growth and replication of the chloroplasts.
Structural Differentiation of the Nucellar Epidermis in the Caryopsis of Rice (Oryza sativa)
It is proposed that the geometry of the nucellar cells and the ribs of wall-thickening are structural adaptations to resist the compressional force which is placed on thenucellar epidermis during the latter stages of grain filling.
Phenotypic differentiation in fitness related traits between populations of an extremely rare sunflower: Conservation management of isolated populations
Detection of rare paternal chloroplast inheritance in controlled crosses of the endangered sunflower Helianthus verticillatus
The findings of occasional paternal transmission of the chloroplast genome are discussed in the framework of using these markers in studies of population and evolutionary biology both in Helianthus and other angiosperms.
Molecular Modeling Indicates that Two Chemically Distinct Classes of Anti-Mitotic Herbicide Bind to the Same Receptor Site(s)
A three-dimensional molecular analysis revealed remarkable electrostatic similarity between dinitroaniline and phosphorothioamidate herbicides, and it is proposed that these two classes of herbicides share common binding site in the plant cell.
Tissue-specific expression of a pea legumin gene in seeds of Nicotiana plumbaginifolia
A 3.4-kilobase genomic DNA fragment from Pisum sativum L. containing the LegA gene, which encodes a major legumin storage protein, was transferred to Nicotiana plumbaginifolia using an Agrobacterium…
