Introduced plants can become invasive when they escape the insect and microbial enemies that control native plant populations. Legumes benefit from symbiotic relationships with nitrogen-fixing bacteria called rhizobia, which colonize nodules in legume roots. We have found that three invasive leguminous plant species (French broom, Spanish broom, and Scotch...

Until recently there was still the idea that when it comes to the microbial world, since it is so small, everything must be everywhere. Much current research is showing this claim does not hold water. Few things are truly everywhere and most things, even on the micro scale, have very...

Bacteriophages (phages, for short) are viruses that attack and kill bacteria. Phages tend to be host specific (specialize on particular bacteria), which allows them to influence bacterial community composition. Legumes are plants that benefit from symbiotic relationships with nitrogen-fixing bacteria called rhizobia, which colonize nodules in legume roots. Rhizobia...

High temperature is an abiotic stress that impedes the growth and productivity of all crops irrespective of their heat tolerance. High temperature affects the development of both vegetative and reproductive structures. It arrests cell proliferation arrest, increases vacuolization, causes over-development of chloroplasts, certain abnormalities in other organelles, and comprehensively...
