Based on DNA sequence analysis of 5 clones of repetitive DNA from alfalfa (Medicago sativa), we propose the existence of a dispersed middle repetitive element about 3400 bp long with a copy number in the range of 2–3 × 103 per haploid genome. The average A + T content of the sequences was 54.6%, compared with 61.4% for the alfalfa genome. Sequence homologies between overlapping regions of the clones ranged from 85 to 89.5% with an average of 86.6%; sequence divergence was due largely to single base pair changes, with deletions or insertions occurring randomly across sequences. An open reading frame (ORF) in one clone, RPE15, contained homologies to cereal prolamin genes and a legumin box was located upstream of the coding region. A Northern blot of RNA from various alfalfa tissues, probed with the above clone containing this ORF, showed an extensive heterodispersed pattern of hybridization in the late stages of flower bud development but in no other tissues. Key words : lucerne, Medicago sativa, repetitive DNA, plant genomes.

Musical Context

This study compared musicians' responses while listening to the first movement of Haydn's Symphony no. 104 using a two-dimensional continuous response digital interface (CRDI). The two-dimensional CRDI uses a mouse cursor via a computer screen to indicate the interrelationship of two dimensions simultaneously. In the present investigation, 50 musicians were presented with the dimensions of arousal (i.e., relaxing-exciting) and affect (i.e., ugly-beautiful). The vertical dimension on the computer screen listed the word “Exciting” at the top and “Relaxing” at the bottom; the horizontal axis listed “Ugly” on the left side and “Beautiful” on the opposite side. Subjects moved the cursor as they tracked their response to the musk. Results indicated that there was an inverse relationship between the two dimensions as subjects tracked responses during this selection. The correlation between the two dimensions was r = −.58. Additionally, graphic analysis indicated almost a mirror-image relationship between the two dimensions. When analyzed within the musical context, both the arousal and the excitement dimensions evidenced many subtle characteristics shown graphically as peaks and valleys corresponding to variations in the music. It was apparent that these two dimensions represent different aspects of perceived listening; the exciting-relaxing dimension representing degrees of arousal that were most often the opposite from subjects' affective response. Additional comparisons were made with previous research that used this identical Haydn selection but measured each dimension separately.
