The Genetics of Vivipary in Maize.

REMATURE germinating seeds have been observed in various plants, including P lemons, oranges, melons, wheat and rye. However, in none of these is there any good indication that the premature germination is the result of changes in the germ plasm. Only in maize has the genetic control of this phenomenon been clearly demonstrated. Such mutants have been described by MANGELSDORF (1923,1926, and 19...

Effects of Irradiance on Crassulacean Acid Metabolism in the Epiphyte Tillandsia usneoides L. (Bromeliaceae).

Spanish moss (Tillandsia usneoides L.) was collected in South Carolina, maintained in a greenhouse, then exposed to five levels of photosynthetic photon flux density (PPFD) for 3 weeks. Following this treatment, plants were sampled for chlorophyll concentrations, nocturnal acid accumulations, and photosynthetic responses to subsequent exposure at a range of PPFD. No acclimation to PPFD was obse...

Facultative Vivipary is a Life-History Trait in Caenorhabditis elegans.

Organisms partition their resources among growth, maintenance, and reproduction and, when resources become limiting, the allocation to one process necessitates reduced allocation to others. When starved, Caenorhabditis elegans adults retain progeny internally which then consume the parent body contents, and some of those larvae use the resources to reach the resistant, long-lived dauer stage. I...

Absorbable phenylpropenoyl sucroses from Polygala tenuifolia.

Three phenylpropenoyl sucroses--sibiricose A5, A6 and 3',6-disinapoyl sucrose--were isolated from the 30% EtOH extract of Polygala tenuifolia, which displayed antidepressant-like action. HPLC analysis indicated that the three phenylpropenoyl sucroses could be absorbed into serum. From the serum pharmacochemistry point of view, these three phenylpropenoyl sucroses might prevent or relieve depres...
