Papain-like cysteine proteases in Carica papaya: Lineage-specific gene duplication and expansion

tailieu.vn

Lineage-specific expansions of PLCP genes are mostly derived from tandem duplication. To examine whether lineage- specific expansions of PLCP genes are driven by genome-wide duplication or tandem duplication events, we carefully looked at the chromosome locations of PLCP genes for two monocot (O. We also used MCScanX to classify the gene duplication events that led to lineage-specific expansions of PLCP genes in the seven selected plant species..

Gene duplications in the E. coli genome: Common themes among pathotypes

tailieu.vn

We then analyzed the map positions of the hha2/hha3 genes and the flu yeeR irmA (aec69) aec70 aec71 gene cluster in the chromo- somes of seven E. This study also showed that in most of the viru- lent E. three copies of hns-like genes (hns, stpA and hns2) [27], two copies of yeeR and irmA (aec69), three copies of flu and four copies of the aec71 gene suggests that gene duplication may play a relevant role in this and perhaps other patho- genic E. Gene duplications in the EAEC strain 042 genome.

GATC: A genetic algorithm for gene tree construction under the Duplication-Transfer-Loss model of evolution

tailieu.vn

For the Most Parsimonious Reconciliation model (MPR), this score corresponds to the optimal number of gene gain and loss events, weighted by their costs, explaining the incongruence between a gene tree and a species tree.. Most integrative methods for gene tree reconstruc- tion assume a simplified model of gene family evo- lution where gene gain events are reduced to gene duplication (e.g.

New insights into the evolution and functional divergence of the CIPK gene family in Saccharum

tailieu.vn

Figure 2 showed the phylogeny of the SsCIPK gene family, which may have undergone six gene duplication events from the LCA of SsCIPK. Except for WGDs, single-gene duplicates also play an important role in the formation of gene families [51].. These observations suggest that single- gene duplication events play important roles in the ex- pansion of SsCIPK gene family in sugarcane.

Genome-wide analysis and characterization of F-box gene family in Gossypium hirsutum L

tailieu.vn

To elucidate the evolutionary genome re- arrangement and duplication patterns of the F-box protein encoding genes in Gossypium hirsutum, we performed a gene duplication event analysis includ- ing whole genome duplication (WGD), tandem duplication (TD), proximal duplication (PD) and transposed duplication (TRD) (Fig.

Genome-wide identification of the class III POD gene family and their expression profiling in grapevine (Vitis vinifera L)

tailieu.vn

Intriguingly, the integrated analysis of chromosomal mapping and gene collinearity analysis proposed that both dispersed and tandem duplication events contributed to the expansion of PODs in grapevine.. Also, the gene duplication analysis suggested that most of the genes (20) were dispersed followed by (15) tandem, (9) segmental or whole-genome duplication, and (3) proximal, respectively.

Genome-wide characterization of the WAK gene family and expression analysis under plant hormone treatment in cotton

tailieu.vn

The phylogenetic tree of the WAK gene family contains WAK gene members from four species: G. The GhWAK genes that clustered together in Fig. This phenomenon indicated that GhWAK genes may originate from gene duplication.. Therefore, we fur- ther analyzed the gene duplication types of the WAK gene family in G.

Expanding dynamics of the virulencerelated gene variations in the toxigenic Vibrio cholerae serogroup O1

tailieu.vn

These results suggest that gene duplication obviously increased the gene se- quence types of core virulence-related genes. Considering the above results, there may be a balance for core virulence-related genes between the diversity driving by gene duplication and the maintenance of functional stability..

Genome-wide identification and expression profiling of trihelix gene family under abiotic stresses in wheat

tailieu.vn

Conclusions: In this study, we identified trihelix genes in wheat and its close relatives and found that gene duplication events are the main driving force for trihelix gene evolution in wheat. Our expression profiling analysis demonstrated that wheat trihelix genes responded to multiple abiotic stresses, especially salt and cold stresses.

Genome-wide identification, expression profiles and regulatory network of MAPK cascade gene family in barley

tailieu.vn

Genome-wide identification, expression profiles and regulatory network of MAPK cascade gene family in barley. Gene duplication analysis revealed that segmental and tandem duplication events contributed to the expansion of barley MAPK cascade genes and the duplicated gene pairs were found to undergone strong purifying selection.

Comparative genomics revealed the gene evolution and functional divergence of magnesium transporter families in Saccharum

tailieu.vn

It is inter- esting that the gene expression correlates with the evolutionary history of the 4 MGTs in Saccharum, as demonstrated by the results that rank the expression levels as SsMGT10 >. In clade D, SsMGT7 and SsMGT8 originated from the LCA of the second-round gene duplication in angiosperms by a recent gene duplication event which occurred after the divergence of monocots and dicots.

Comparative analysis of plant MKK gene family reveals novel expansion mechanism of the members and sheds new light on functional conservation

tailieu.vn

Multiple duplication events were identified in each group The major force of the evolution of different species comes from gene duplication, which causes the gene to generate the gene families. In order to further understand the dupli- cation and evolution events of the MAPKK genes, we also investigated the duplicated genes in plant genome from each orthology group (Additional file 9).

Comprehensive genomic analysis of the CNGC gene family in Brassica oleracea: Novel insights into synteny, structures, and transcript profiles

tailieu.vn

We investigated gene duplication events to clarify the genome expansion mechanism of the B. An evaluation of the physical distance between BoCNGC gene loci revealed that eight genes (i.e., BoCNGC18 / BoCNGC19 , BoCNGC21/BoCNGC22/BoCNGC24 , and BoCNGC20/BoCNGC25/BoCNGC26 ) were tandemly du- plicated. The BoCNGC gene clusters likely formed via tandem and segmental duplication events may have expanded and enhanced the functional diversity of the gene family..

Identification, evolution and expression analyses of whole genome-wide TLP gene family in Brassica napus

tailieu.vn

In conclusion, we comprehensively analyzed the evolution- ary pattern, gene structure, orthologous and paralogous genes, duplication type, gene synteny, gene duplication or losses, and gene expression pattern of TLP genes in B.. Therefore, this is the first comprehensive and systematic analyses of TLP gene family in B. This study provides useful resources for future studies on the structure and function of TLP genes in B.

tailieu.vn

Monocot-specific gene duplication events have also been detected in the MKK family. gene duplication was also observed here in the Triticeae tribe. 4 of each of the three wheat genomes (A, B and D). In wheat, there were no major differences in the abundance of the TaMPK4 transcript compared with other MPKs in the spikelet during anthesis (54 DAS) or post-anthesis (72 DAS) (Fig.

Genome-wide identification and functional characterization of the Camelina sativa WRKY gene family in response to abiotic stress

tailieu.vn

Segmental duplication contributed critically to the expansion of the CsWRKY gene family in evolution Increasing numbers of reports have indicated that gene duplication (e.g., tandem duplication, segmental duplica- tion, and genome duplication) was the key force for gene family expansion in plant genomes [50]. Here, the genome-wide identification and analysis of the WRKY gene family in C.

Identification of CBL and CIPK gene families and functional characterization of CaCIPK1 under Phytophthora capsici in pepper (Capsicum annuum L.)

tailieu.vn

In the gene duplication analysis, we found that the CaCBL family underwent two segmental duplication events (CaCBL1. These results suggested that segmental duplications may have contributed to the com- plexity and diversity of both gene families. AtCBL5-AtCIPK24 proteins are lo- calized to the plasma membrane.
