The DNA sequence properties of 5S DNA (5S RNA gene plus spacer) from a wide range of families of plants is reviewed with particular reference to the possibility of using the information for phylogenetic inference. Although the data-base is extremely limited, the available evidence suggests that within a subclass or tribe phylogenetic inference can be made,(More)
Although the matK gene has been used in addressing systematic questions in four families, its potential application to plant systematics above the family level has not been investigated. This paper examines the rates, patterns, and types of nucleotide substitutions in the gene and addresses its utility in constructing phylogenies above the family level.(More)
The use o f energy (calories) as the currency to be maximized per unit time in Optimal Foraging Models is considered in light o f data on several foraging groups. Observations on the Ache, Cuiva, and Yora foragers suggest men do not attempt to maximize energetic return rates, but instead often concentrate on acquiring meat resources which provide lower(More)
Random amplified polymorphic DNA fingerprinting was used to examine 31 mosquito-pathogenic and 14 nonpathogenic strains of Bacillus sphaericus. We verified that DNA bands that migrated the same distance in an agarose gel were homologous by using PCR-generated probes made from the random amplified polymorphic DNA bands. The band patterns obtained with eight(More)
Oryza L. (Poaceae) contains approximately 20 wild and two domesticated species and nine genomes. Major disagreements exist on its systematics and genome evolution. Sequence polymorphism in the gene that encodes the 10-kDa prolamin polypeptide (a seed storage protein) was used to determine phylogenetic relationships and evaluate current systematics for 19(More)
Prolamin is the dominant class of seed storage protein in grasses (Poaceae). Information on the 10 kDa multigene family coding for prolamins characteristic of the bambusoid-oryzoid grasses is limited. Two genes encoding 10 kDa prolamin were cloned and sequenced in the bambusoid species Phyllostachys aurea to assess the sequence diversity of this gene family(More)
