The phylogeny of baobab trees was analyzed using four data sets: chloroplast DNA restriction sites, sequences of the chloroplast rpl16 intron, sequences of the internal transcribed spacer (ITS) region of nuclear ribosomal DNA, and morphology. We sampled each of the eight species of Adansonia plus three outgroup taxa from tribe Adansonieae. These data were analyzed singly and in combination usin...

Diel (24 h) courses of CO(2) and water-vapor exchange of Ceiba pentandra (L.) Gaertn. (Bombacaceae) were studied under natural tropical conditions in the semi-evergreen moist forest of Barro Colorado Island, Panama. Measurements were conducted from early February 1991 (dry season), shortly after new leaves emerged, until mid-October 1991 (wet season), when leaves were shed. Rates of net CO(2) u...

Isolation of high quality RNA and DNA from plants especially cotton (Gossypium hirsutum; family Malvaceae) is notoriously difficult. This problem has been attributed to high content of phenolic terpenoids and tannins present in cotton cells (Katterman, and Shattuck, 1983). These compounds bind to RNA and DNA upon cell lysis and cannot be removed by conventional extraction procedures. Such RNA i...
