Evolutionary studies in sub-families of Leguminosae family based on
matK
gene
6
Vigna aconitifolia
doesn’t share common node with
any species of
Vigna
species. While there is no change
if we compare two figures 5 and 5.1 and we observed
that there are many species of same genus which have
not changed in both results and their sequential order
remains unchanged. So, there might be strong sequence
similarity between species that they remain unchanged
in two different results which are done with two
different methods.
B. Results of
PROTEIN MATK
Gene Sequences
2.1 Caesalpiniaceae Subfamily
Figure 6. Result by Max.Likelihood Bootstrap Method
In Figure 6, species of
Cassia, Caesalpinia, Delonix
and
Bauhinia
genus are related as per morphological
characters or botanical classifications but
Parkinsonia
aculeata
found between species of
Delonix
genus, so it
may be closely related with species of
Delonix
genus.
Figure 6.1 Result by NJ Bootstrap Method
In Figure 6.1, it shows that even single species of
Cassia
,
Caesalpinia, Delonix
and
Bauhinia
genus are
not distantly related; they are all related very closely
and their sequential order also remain unchanged when
we compare these two results which follow different
methods of analysis.
So, the NJ method gives the more accurate result of
evolutionary relationship of Caesalpiniaceae subfamily
as per morphological or taxonomical classification
where the results were based on
matK
protein
sequences and species remain unchanged and fall
within their genus which is true as per their
taxonomical classification.
2.2 Mimosaceae Subfamily
As shown in Figure 7, species of genus
Albizia
and
species of
Acacia
genus are related as per morphological
characters or botanical classifications except
Albizia
lebbeck
which is not closely related with
Albizia,
whereas species of
Albizia
genus are correctly related
with each other as per botanical classification
.
As shown in Figure 7.1,
Albizia
and
Acacia
genus are
related as per morphological characters or botanical
classifications except
Acacia senegal
and but
Pithecellobium dulce
fall within
Albizia
genus which is
homologous with other species of
Albizia
. If we
compare Figures 4 and 4.1, it was observed that species
like
Acacia farnesiana and Acacia nilotica;
their
