Genus and System
Methods and Conclusion
Reference
Geonoma genus PRK
RPB2
11 taxa of Central America, 4 from French Guiana,
1 from Bolívia, 1 of Peruvian Andes analyzed
sequence variations of intron 4 of PRK and
intron 23 of RPB2 and range map data and 12
environmental factors for all Geonoma species
[17]
Geonoma—ISSR
31 individuals of 2 varieties of
G. macrostachys
at 4 locations of western Amazon (acaulis,
macrostachys); 27 ISSR primers—99 bands-52
polymorphic; 2 main groups seen by geographical
provenance
[18]
Geonomae tribe—
PRK & RPB2
46 species of 6 genera of geonomae, 14 of Arecoideae,
2 of Ceroxyloideae, 1 of Phytelephantoideae
analysed by PRK, RPB2 sequence variations;
Geonoma is monophyletic with 2 main clades
[19]
Howea—AFLP
48 primer pairs initially and pairs B13, G7, and Y1
gave 274 AFLP bands on 2 species; high degree of
homogeneity in 2 species
[20]
Johannesteijsmannia—
SSR
24 samples
of J. lanceolata
using 31 polymorphic
microsatellite markers helped understand mating
system, heterozygosity. These markers are also
cross transferrable to
J. altifrons, J. magnifica,
and
J. perakensis
[21]
Livistona
L. carinensis
is a vulnerable species in Africa limited
to yemen, Djibouri, and Somalia. Nine SSR loci
screened in 3 populations of Djibouri, Yemen, and
Somalia. Djibouri monomorphic across all loci; other
populations in botanic gardens as few individuals
display heterozygosity and diverse than Djibouri
[22]
Livistona & Licuala-
six-locus cpDNA
data, MS intron
18 Australian Livistona species & other taxa across tribe
Trachycarpeae analyzed by 1 nDNA (malate synthase,
MS) and 6 cpDNA loci (total of 4000 kb); Livistona
is a monophyletic genus and sister to Licuala grandis
based on 6 cp loci psbB-psbF, rpl20-
rps
12, trnT-
trnD, trnS-P-trnfM-M (psbZ), trnL intron, and trnL-
trnF exons and intergenic spacer, and MS; MS proved
as a fast evolving locus in Livistona
[23]
Lodoicea—AFLP
180 trees of
L. maldivica
at 1 population each of 2
islands (Praslin and Curieuse) of Seychelles Indian
Ocean; weak genetic differentiation between 2
populations
[24]
Metroxylon—AFLP
76 accessions of
M. sagu
, collected in 7 wild and
semi-wild stands in Papau New Guinea; showed
a significant correlation between genetic and
geographical distances
[25]
