Species of the temperate woody bamboo genus Kuruna Attigala, Kathriar. & L.G. Clark (Poaceae: Bambusoideae) distributed in Sri Lanka and southern India, are threatened due to deforestation and habitat fragmentation. The current study focused on the tetraploid woody bamboo Kuruna debilis (Thwaites) Attigala, Kathriar. & L.G. Clark, using twelve variable microsatellite loci to assess the genetic diversity and population structure in six known Sri Lankan populations. Due to the rarity of the…

Genetic diversity and structure of Dendrocalamus hamiltonii natural metapopulation: a commercially important bamboo species of northeast Himalayas
The study has revealed useful nSSR markers for D. hamiltonii, which were lacking earlier and the information generated herein is of paramount importance in devising programs for species conservation and genetic improvement.
Genetic diversity, population structure, and gene flow analysis of lowland bamboo [Oxytenanthera abyssinica (A. Rich.) Munro] in Ethiopia
Using inter‐simple sequence repeat markers, strong evidence is found that the genetic diversity of the lowland bamboo is associated with distinct geographic regions and that isolates of Gambella Region, with their unique genetic origin, are quite different from other bamboos found in the country.
Genetic structure and diversity of native Guadua species (Poaceae: Bambusoideae) in natural populations of the Brazilian Amazon rainforest.
It can be conclude that populations in natural populations in the Southwestern region of the Brazilian Amazon should be treated as having unique characteristics, mainly when accessed for management and for in situ and ex situ conservation studies.
Population genetic structure of the giant panda staple food bamboo (Fargesia spathacea complex) and its taxonomic implications
It is suggested that altitudinal differences might account for the distinct genetic divergence between the two major groups in the F. spathacea complex, and the identity of three species is confirmed and the invalidation of four other species is suggested.
It can be conclude that populations should be treated as having unique characteristics, mainly when accessed for management and for in situ and ex situ conservation studies.
Ecophysiology and genetic diversity in species of the bamboo Chusquea in the high Andes, Venezuela
ABSTRACT Background: Woody bamboos of the genus Chusquea grow along a broad range of elevations in the Venezuelan Andes. Their growth-form and density vary along the cloud forest – páramo gradient.
Morphologic and genetic variability of Chusquea fendleri Munro ( Bambusoideae : Poaceae ) in Venezuela
Based on the morphological and genetic analysis, two morphological phenotypes of C. fendleri are recognized and a potentially new, sister species is recognized.


A new genus and a major temperate bamboo lineage of the Arundinarieae (Poaceae: Bambusoideae) from Sri Lanka based on a multi-locus plastid phylogeny
Although the Kishino-Hasegawa test is unable to reject the alternative hypothesis of monophyly of the Sri Lankan clade plus Bergbambos tessellata from South Africa, Kuruna and Bergb Ambos are distinguishable by a combination of morphological characters.
Taxonomic Revision of the Temperate Woody Bamboo Genus Kuruna (Poaceae: Bambusoideae: Arundinarieae)
This revision includes an updated description of the genus Kuruna, detailed descriptions for all seven species, line illustrations for all species, and a morphological key for their identification.
Population genetic structure, genetic diversity, and natural history of the South American species of Nothofagus subgenus Lophozonia (Nothofagaceae) inferred from nuclear microsatellite data
The population genetics of three closely related, hybridizing species of Nothofagus allowed us to reconstruct the influence of the last ice age on the genetic structure of these species, suggesting several centers of genetic diversity for N. obliqua and N. alpina in the northern populations.
Relationship between population size, allozyme variation, and plant performance in the narrow endemic Cochlearia bavarica
It is concluded that at present population size reduces viability and also reduces allelic variation; but the reduced allelicVariation may in the longerterm have negative feed-backs on both population size and viability.
Microsatellite variation within and among North American lineages of Phragmites australis
Patterns of differentiation in 10 microsatellite loci among North American and European Phragmites individuals are compared with results obtained from sequencing of noncoding chloroplast DNA, emphasizing that native, introduced and Gulf Coast North American PhragMites lineages are genetically distinct.
RAPD variation in relation to population size and plant fitness in the rare Gentianella germanica (Gentianaceae).
It is concluded that gene flow among natural populations is very limited and that reduced plant fitness in small populations of G. germanica most likely has genetic causes, and management should aim to increase the size of small populations to minimize further loss of genetic variation.
Development of microsatellite markers for the dwarf bamboo species Sasa cernua and Sasa kurilensis (Poaceae) in northern Japan
Ten polymorphic microsatellite markers were isolated from the dwarf bamboo species Sasa cernua and Sasa kurilensis and will be useful in detailing the extent of clonal and sexual reproduction in these species.
Comparative results of RAPD and ISSR markers for genetic diversity assessment in Melocanna baccifera Roxb . growing in Mizoram State of India
The genetic similarity among 12 accessions of Melocanna baccifera from Mizoram in India was tested using RAPD and ISSR markers and the correlation coefficient (r) was found as r = 0.1902, which shows high polymorphism of DNA fragments.
Genetic Relationships Among 22 Taxa of Bamboo Revealed by ISSR and EST-Based Random Primers
The grouping of species based on Jaccard’s similarity matrix using UPGMA and principal coordinate analysis agreed with earlier published reports on molecular phylogenetic studies in bamboos with few deviations, but in the dendrogram, species of one genus were placed in different clusters.
Identifying Populations for Conservation on the Basis of Genetic Markers
The methods proposed to identify prior- ity areas for conservation of the genetic resources of the argan tree are compared to those sometimes advo- cated in the case of reserve design, where one of the goals is to maximize species richness.
