Evaluating approaches to the conservation of rare and endangered plants and their impacts on threatened and endangered species in the wild is a good place to start.
Molecular systematics and evolution of Arabidopsis and Arabis
: We provide a phylogenetic analysis of the genera Arabidopsis and Arabis based on nuclear ribosomal DNA sequences. We show that traditional taxonomical concepts within tribe Ara-bideae, which…

It is shown that nonsynonymous substitution rates in plant class I chitinase often exceed synonymous rates in the plant genus Arabis (Cruciferae) and in other dicots, indicating a succession of adaptively driven amino acid replacements, suggesting that fungi directly defend against chitinolytic activity through enzymatic inhibition or other forms of chemical resistance.
Trophic Interactions during Primary Succession: Herbivores Slow a Plant Reinvasion at Mount St. Helens
It is found that removing insect herbivores increased both the areal growth of individual l upine plants and the production of new plants in the edge region, thereby accelerating the lupine’s intrinsic rate of increase at the front of the lUPine reinvasion.
Plant-pathogen arms races at the molecular level.

This work demonstrates that populations of the rare endemic plant Arabis fecunda are physiologically adapted to the local microclimate and provides empirical evidence that setting conservation priorities based exclusively on molecular marker diversity may lead to the loss of locally adapted populations.

Causes and Consequences of Herbivory on Prairie Lupine (Lupinus lepidus) in Early Primary Succession
Primary succession, the formation and change of ecological communities in locations initially lacking organisms or other biological materials, has been an important research focus for at least a…
In vitro growth inhibition of mastitis-causing coliform bacteria by bovine apo-lactoferrin and reversal of inhibition by citrate and high concentrations of apo-lactoferin

Results are compatible with the hypothesis that coliform bacteria respond to low-iron environments by production of iron-sequestering agents that complete effectively with apo-Lf for free iron and suggest that the ratio of citrate to Lf would be important in evaluating Lf as a nonspecific protective factor of bovine mammary secretions.
Identification of target amino acids that affect interactions of fungal polygalacturonases and their plant inhibitors
The results complement existing molecular and biochemical studies of resistance specificity, and suggest new target amino acids for manipulating PG-inhibition, which are likely to evolve adaptively in response to natural selection.
