The roots nodules present in the legume plants are characteristically formed as a result of a mutualistic relationship with bacteria involved in nitrogen fixation ( Bradyrhizobium and Rhizobium ). The relationship is formed as the nod gene products of the bacteria that permits it to infect the cells of root cortex and then proliferate.

In this activity you will analyze the results of experiments that investigate nutritional requirement of several mutant strains of yeast. The mutations in these strains cause a nutritional requirement for an amino acid, such that the strains will not grow in media that lack one specific amino acid. Any mutant that has a nutritional requirement is called an auxotroph, and is incapable of growing in a "minimal medium" containing only a carbon source (e.g., glucose), a simple nitrogen source (e.g., ammonium sulfate), and various salts and minerals. Such strains can be supported on a medium supplemented with only the missing nutrient or on a "rich" medium that contains amino acids, vitamins, nitrogenous bases, etc. (often in the form of an extract from yeast). The wild-type individual that can synthesize the metabolic component is a prototroph, and is capable of growth on minimal medium. The mutant strains in this activity are unable to synthesize tryptophan, lysine, or histidine; one…

According to data from genome sequences, cytoplasmic dynein is absent in some plants (e.g.,Arabidopsis) and present in others (e.g.,rice).Does this ﬁnding surprise you? What else might you do to conﬁrm or refute such a statement? How is it possible that higher plant cells could operate without cytoplasmic dynein?

The figure below shows the life cycle of the fungus Neurospora. The adult stage of the Neurospora is a multicellular haploid: a. Between which two stages of the Neurospora life cycle do most mitotic cell divisions occur? b. Neurospora has an arginine amino acid synthesis pathway shown below: Suppose I have a neurospora strain that has a mutation such that it will not grow unless I supplement the media (food) with arginine (but not with citrulline or ornithine). What gene is mutated? Explain your reasoning. c. Suppose I take the strain above that only grows with arginine supplements and cross it to a different mutant Neurospora strain that grows with arginine and citrulline supplements but not ornithine supplements. Assming genes A, B and C are unlinked and there is only one mutation per strain: i) What percentage of the progeny will grow on ornithine? ii) What percentage on citrulline? iii) What percentage on arginine? Show your work for i), ii) and iii). [Can be answered in less…
