| rotylenchulus reniformis on greenhouse-grown foliage plants: host range and sources of inoculum. | two sources of inoculum of reniform nematodes, rotylenchulus reniformis, were identified for infestation of ornamental foliage plants in commercial greenhouses. these were water from a local canal system and rooted cuttings purchased from other sources. eight ornamental plant species were identified as good hosts for the reniform nematode, with each species supporting a reniform population density equal to or greater than that supported by 'rutgers' tomato and a reproduction factor of greater th ... | 1991 | 19283176 |
| compound leaf development in the palm chamaedorea elegans is knox-independent. | how a leaf acquires its shape is a major and largely unresolved question in plant biology. this problem is particularly complex in the case of compound leaves, where the leaf blade is subdivided into leaflets. in many eudicots with compound leaves, class i knotted1-like homeobox (knox) genes are upregulated in the leaf primordium and promote leaflet initiation, while knox genes are restricted to the shoot apical meristem in simple-leaved plants. in monocots, however, little is known about the ex ... | 2011 | 21911452 |
| [bionomics data and descriptions of the immatures of calyptocephala gerstaeckeri boheman (coleoptera: chrysomelidae), pest of the oil palm (elaeis guineensis j.) and camedor palm (chamaedorea elegans mart.) (arecaceae) in tabasco, mexico]. | characters of the external morphology of egg, larval instars and pupae of calyptocephala gerstaeckeri boheman, insect pest of oil palm (elaeis guineensis j.) and camedor palm (chamaedorea elegans mart.) in the state of tabasco, mexico, are described and illustrated. some bionomics data are also presented. the specie was reared in the laboratory on young oil palm plants. | 2009 | 19169555 |
| permanent genetic resources: development of microsatellite markers of the mexican understorey palm chamaedorea elegans, cross-species genotyping, and amplification in congeners. | with striking morphological diversity and adaptability, chamaedorea palms constitute an ecologically and economically important understorey component of neotropical forests. nine loci developed for chamaedorea elegans evaluated in three veracruz populations resulted in a large number of alleles (8-18), and high expected heterozygosity (0.49-0.92), but low observed (0.27-0.65) heterozygosity. deviations from hardy-weinberg and high inbreeding suggest a lack of panmixia. eight loci optimized for c ... | 2008 | 21585780 |
