| inheritance of factors affecting floral primordia initiation in cestrum; hybrids of c. elegans and c. nocturnum. | photoperiod patterns of hybrids of cestrum elegans (brongn.) schlect., a day neutral plant, and c. nocturnum l., a long-short day and long day plant, were investigated. plants of the f(1) generation, f(2) generation, and backcrosses to each parent were tested on short day, long day, continuous light, long-short day and short-long day for floral primordia initiation. the data recorded suggest 2 independent genes or gene groups controlling floral primordia initiation in c. nocturnum, a single domi ... | 1966 | 16656219 |
| differential effects of naa and 2,4-d in reducing floret abscission in cestrum (cestrum elegans) cut flowers are associated with their differential activation of aux/iaa homologous genes. | a previous study showed that the relative effectiveness of 2,4-dichlorophenoxyacetic acid (2,4-d) compared with that of 1-naphthaleneacetic acid (naa) in reducing floret bud abscission in cestrum (cestrum elegans) cut flowers was due to its acropetal transport. the aim of the present study was to examine if the differential effect of these auxins on floret abscission is reflected in the expression of aux/iaa genes in the floret abscission zone (az). | 2008 | 17591611 |
| characterisation of an unusual telomere motif (ttttttaggg)n in the plant cestrum elegans (solanaceae), a species with a large genome. | the characterization of unusual telomere sequence sheds light on patterns of telomere evolution, maintenance and function. plant species from the closely related genera cestrum, vestia and sessea (family solanaceae) lack known plant telomeric sequences. here we characterize the telomere of cestrum elegans, work that was a challenge because of its large genome size and few chromosomes (1c 9.76 pg; n = 8). we developed an approach that combines bal31 digestion, which digests dna from the ends and ... | 2015 | 25828846 |
