Transcriptome and metabolome analyses reveal anthocyanins pathways associated with fruit color changes in plum ( Lindl.).

Plum ( Lindl.) is one of the most widely cultivated and important fruit trees in temperate and cold regions. Fruit color is a significant trait relating to fruit quality in plum.

Transcriptional regulation of bark freezing tolerance in apple (Malus domestica Borkh.).

Freezing tolerance is a significant trait in plants that grow in cold environments and survive through the winter. Apple (Malus domestica Borkh.) is a cold-tolerant fruit tree, and the cold tolerance of its bark is important for its survival at low temperatures.

Cloning, molecular and functional characterization by overexpression in Arabidopsis of MAPKK genes from grapevine (Vitis vinifera).

Background: The mitogen-activated protein kinases (MAPKs), as a part of the MAPKKK-MAPKK-MAPK cascade, play crucial roles in plant development as an intracellular signal transduction pathway to respond various environmental signals. However, few MAPKK have been functionally characterized in grapevine.

Results: In the study, five MAPKK (MKK) members were identified in grapevine (cultivar 'Pinot Noir'), cloned and designated as VvMKK1-VvMKK5.

Genome-wide identification and analysis of mitogen activated protein kinase kinase kinase gene family in grapevine (Vitis vinifera).

Background: Mitogen-activated protein kinase kinase kinases (MAPKKKs; MAP3Ks) are important components of MAPK cascades, which are highly conserved signal transduction pathways in animals, yeast and plants, play important roles in plant growth and development. MAPKKKs have been investigated on their evolution and expression patterns in limited plants including Arabidopsis, rice and maize.

Results: In this study, we performed a genome-wide survey and identified 45 MAPKKK genes in the grapevine genome.

Construction and validation of a gene co-expression network in grapevine (Vitis vinifera. L.).

Gene co-expression analysis has been widely used for predicting gene functions because genes within modules of a co-expression network may be involved in similar biological processes and exhibit similar biological functions. To detect gene relationships in the grapevine genome, we constructed a grapevine gene co-expression network (GGCN) by compiling a total of 374 publically available grapevine microarray datasets. The GGCN consisted of 557 modules containing a total of 3834 nodes with 13 479 edges.

Genome and transcriptome analysis of the grapevine (Vitis vinifera L.) WRKY gene family.

The plant WRKY gene family represents an ancient and complex class of zinc-finger transcription factors (TFs) that are involved in the regulation of various physiological processes, such as development and senescence, and in plant response to many biotic and abiotic stresses. Despite the growing number of studies on the genomic organisation of WRKY gene family in different species, little information is available about this family in grapevine (Vitis vinifera L.).
