The plant sucrose nonfermenting 1 (SNF1)-related protein kinases (SnRKs) are key regulators in the interconnection of various signaling pathways. However, little is known about the SnRK family in strawberries. In this study, a total of 26 FvSnRKs including one FvSnRK1, nine FvSnRK2s and 16 FvSnRK3s were identified from the strawberry genome database. They were respectively designated as FvSnRK1.1, FvSnRK2.1 to FvSnRK2.9 and FvSnRK3.1 to FvSnRK3.16, according to the conserved domain of each subfamily and multiple sequence alignment with Arabidopsis. FvSnRK family members were unevenly distributed in seven chromosomes. The number of exons or introns varied among FvSnRK1s, FvSnRK2s and FvSnRK3s, but highly conserved in the same subfamily. The FvSnRK1.1 had 10 exons. Most of FvSnRK2s had nine exons or eight introns, except FvSnRK2.4, FvSnRK2.8 and FvSnRK2.9. FvSnRK3 genes were divided into intron-free and intron-harboring members, and the number of introns in intron-harboring group ranged from 11 to 15. Moreover, the phylogenetic analysis showed SnRK1, SnRK2 and SnRK3 subfamilies respectively clustered together in spite of the different species of strawberry and Arabidopsis, indicating the genes were established prior to the divergence of the corresponding taxonomic lineages. Meanwhile, conserved motif analysis showed that FvSnRK sequences that belonged to the same subgroup contained their own specific motifs. Cis-element in promoter and expression pattern analyses of FvSnRK1.1 suggested that FvSnRK1.1 was involved in cold responsiveness, light responsiveness and fruit ripening. Taken together, this comprehensive analysis will facilitate further studies of the FvSnRK family and provide a basis for the understanding of their function in strawberry.

Abstract Background: Adenylate kinase (ADK) is widely distributed in organisms and plays an important role in cellular energy homeostasis. In plants, ADK has important functions in plant growth and development regulation as well as adaptation to the environment. However, little information is available about the ADK genes in tomato (Solanum lycopersicum), an important economic crop.Results: To investigate the characteristics and functions of ADK genes in tomato, a total of 11 ADK genes were identified and named according to their chromosomal locations. The ADK family was divided into five groups and motif analysis revealed that each SlADK protein contained five to eight conserved motifs. Sequence analysis revealed 4-19 exons in all SlADKs and most members possessed four. The 11 SlADKs were randomly distributed on nine of the 12 tomato chromosomes. A cis-element analysis inferred that several stress response elements were found on the promoters of SlADKs. The online TomExpress platform prediction revealed that SlADKs were expressed in various tissues and organs, basically consistent with the data obtained from real-time quantitative PCR (qPCR). The qPCR verification was also used to determine the expression level of SlADKs and demonstrated that the genes responded to multiple abiotic stresses, such as drought, salt and cold. For example, almost all SlADKs contained two expression peaks at 9 and 48 h following salt treatment. The qPCR results showed that SlADK transcription was responsive to most of the applied hormone treatment: methyl jasmonate, ethylene, salicylic acid, indole 3-acetic acid and abscisic acid. Notably, SlADK2 and 4 exhibited significant changes under multiple stress treatments.Conclusions: These results provide valuable information for clarifying the evolutionary relationship of the tomato ADK family and in aiding functional characterization of SlADKs in further research.

Abstract Background Teosinte branched1/Cycloidea/Proliferating cell factor (TCP) proteins are plant-specific transcription factors, which widely involved in leaf development, flowering, shoot branching, and circadian rhythm. So far, TCP proteins function in tumorous stem mustard has not been reported. . Here we identified and characterized the entire TCP protein family members in the tumorous stem mustard. Results We identified fifty-four TCP genes in Brassica juncea var. tumida, containing thirty-three Class I subfamily members and twenty-one Class II subfamily members. Fifty-three TCP genes are distributed on 15 chromosomes. Gene structure and conserved motif analysis showed that the same clade genes have similar gene intron/exon structure and conserved motifs. Cis-acting element results showed that the same clade genes also have similar cis-element, however subtle differences also imply the different regulated pathway. More than twice paralogs genes relation to diploid species in some members imply gene duplication events in evolution. The members of BjTCP18s are low expressed in DY strains and un-swelling stage of YA strains. After treatment with GA and SA, it was detected that the expression levels of multiple TCP genes were affected by these two hormones. Conclusion In this study, we perform the first genome-wide analysis of the tumorous stem mustard TCP gene family. The results provide valuable information for understanding the classification and functions of TCP genes in tumorous stem mustard.

And Function

Eggplant (Solanum melongena L.) is an important vegetable cultivated in Asia, Africa and southern Europe and, following tomato and pepper, ranks as the third most important solanaceous vegetable crop. The Dof (DNA-binding with one finger) family is a group of plant-specific transcription factors that play important roles in plant growth, development, and response to biotic and abiotic stresses. The genes in the Dof family have been identified and analysed in many plant species, but the information remains lacking for eggplant. In the present study, we identified 29 SmeDof members from the eggplant genome database, which were classifed into nine subgroups. The phylogeny, gene structure, conserved motifs and homologous genes of SmeDof genes were comprehensively investigated. Subsequently, we analysed the expression patterns of SmeDof genes in six different eggplant subspecies. The results provide novel insights into the family of SmeDof genes and will promote the understanding of the structure and function of Dof genes in eggplant, and the role of Dof expression during stress.

Carrot (Daucus carota L.) is a crop with rich nutritional value and is one of the most important economical horticulture crops worldwide. The TEOSINTE BRANCHED 1, CYCLOIDEA, PROLIFERATING CELL FACTORS (TCP) transcription factor (TF) family plays important roles in several physiological processes; However, TCP TFs in carrot are rarely reported. In this study, 36 D. carota TCP (DcTCP) TFs were identified from the carrot genome database. On the basis of phylogenetic relationship with TCP TFs in Arabidopsis, the DcTCP family was divided into two classes, namely class I and class II (including CIN and CYC/TB1 subclass). The number of DcTCP TFs in classes I and II were 22 and 14, respectively. Motif analysis and chromosome location of DcTCP TFs were also conducted. All of the DcTCP genes were distributed on nine chromosomes of carrot. The distribution of TCP TFs in different species indicates that the number of TCP TFs is consistent with plant evolution. Quantitative real-time PCR assay was performed to further understand the expression patterns of DcTCP genes during the development of carrot. The expression levels of DcTCP33 and DcTCP36 increased with the germination of carrot seed. The CIN subclass of DcTCPs (DcTCP1, DcTCP4, and DcTCP5) was primarily expressed in leaf blades, whereas the DcTCP26 gene was mainly expressed in roots. These results can provide potentially useful information about TCP TF identification and help explain the roles of TCP TFs in carrots.

Tcp Family

Background Teosinte branched1/Cycloidea/proliferating cell factors (TCPs) are plant-specific transcription factors widely involved in leaf development, flowering, shoot branching, the circadian rhythm, hormone signaling, and stress responses. However, the TCP function in Brassica juncea var. tumida, the tumorous stem mustard, has not yet been reported. This study identified and characterized the entire TCP family members in B. juncea var. tumida. Methods We identified 62 BjTCP genes from the B. juncea var. tumida genome and analyzed their phylogenetic relationship, gene structure, protein motifs, chromosome location, and expression profile in different tissues. Results Of the 62 BjTCP genes we identified in B. juncea var. tumida, containing 34 class I and 28 class II subfamily members, 61 were distributed on 18 chromosomes. Gene structure and conserved motif analysis showed that the same clade genes displayed a similar exon/intron gene structure and conserved motifs. Cis-acting element results showed that the same clade genes also had a similar cis-acting element; however, subtle differences implied a different regulatory pathway. The BjTCP18s members were low-expressed in Dayejie strains and the unswelling stage of Yonganxiaoye strains. Treatment with gibberellin (GA) and salicylic acid (SA) showed that GA and SA affect the expression levels of multiple TCP genes. Conclusion We performed the first genome-wide analysis of the TCP gene family of B. juncea var. tumida. Our results have provided valuable information for understanding the classification and functions of TCP genes in B. juncea var. tumida.
