Chloroplast DNA evolves slowly in the palm family (Arecaceae).
A survey of cpDNA restriction-site variation for 22 species representing five of the six subfamilies of the palm family was conducted. Phylogenetic reconstructions based on the restriction-site data are in general agreement with conventional analyses based on morphological characters. Base-substitution estimates, derived from the restriction-site data, indicate a potential 5-13-fold decrease in...
متن کاملMicrosatellites in palm (Arecaceae) sequences
Microsatellites are the most promising co-dominant markers, widely distributed throughout the genome. Identification of these repeating genomic subsets is a tedious and iterative process making computational approaches highly useful for solving this biological problem. Here 38,083 microsatellites were localized in palm sequences. A total of 2, 97,023 sequences retrieved from public domains were...

15 صفحه اولStem anatomy in the spiny american palm Bactris (Arecaceae-Bactridinae)
(Stem anatomy in the spiny american palm Bactris (Arecaceae-Bactridinae)). Bactris trunks are made entirely by long sustained primary growth so that mechanical properties develop progressively as the trunk matures. Anatomical features vary throughout the stem so that one small sample is a limited representation. This limits the use for stem histology with systematic purposes. We examined stem a...
متن کاملDevelopmental features of the discontinuous stem vascular system in the rattan palm Calamus (Arecaceae-Calamoideae-Calamineae).
Calamus is a climbing palm marked by considerable internodal extension and limited stem-thickening growth, but with a surprisingly discontinuous axial vascular system. Stem bundles end blindly in a basipetal direction and are connected to each other only by narrow and late-developing transverse commissures. Vascular connection via leaf traces between stem and leaf is made over about nine plasto...
