“…Phytohormones, such as ABA, IAA and GA, are involved in various stress signaling pathways, and play significant roles in alleviating adverse abiotic stresses in plants, along with multiple other biological functions [67][68][69][70][71][72][73]. To elucidate the potential functions of CaSTP genes in response to exogenous phytohormones, we analysed available data about the expression profiles of CaSTP genes in leaves and roots treated with these exogenous substances (Figure 8).…”

Sugar transporter proteins (STPs) play an important role in plant growth and development and stress resistance. Pepper (Capsicum annuum L.) is a significant economic crop and is widely cultivated worldwide. However, the evolution and the roles of STP genes in the growth and development and in coping with abiotic stresses in pepper are poorly known. Here, we characterized STP gene family in pepper through integration of chromosomal location, gene structure, conserved motif, phylogeny, expression patterns in different tissues and abiotic stresses. Using bioinformatics-based methods, we identified 17 putative STP genes in pepper. Chromosome mapping indicated that they are unevenly distributed on 9 chromosomes and there are tandem duplication events. Gene structure analysis revealed that intron numbers among these CaSTP genes ranged from 2 to 5, except that CaSTP12 and CaSTP13 genes contained no introns. The phylogenetic tree of STP genes from pepper and other plant species revealed that STP genes were grouped into 4 subfamilies, suggesting that these gene subfamilies may have diverged from a single common ancestor prior to the mono-dicot split. Gene expression analysis based on RNA-seq data showed that three genes were expressed constitutively in all the tissues analyzed, implying that these genes might have specific function in pepper. Stress data analysis showed that the expression profiles of some members of the CaSTP gene family were altered under cold, heat, salt and hormone stress conditions. The present results will provide valuable information into the evolutionary relationships and functional divergence of the STP family in the future. ARTICLE HISTORY

“…Digital expression profiling is a particularly powerful and efficient method for large-scale gene-expression analysis [48][49][50][51][52][53][54][55], and it contributes to understanding gene functions. We therefore analyzed the expression profiles of the CIN gene family at different types of tissue and developmental stages from S. lycopersicum and S. tuberosum on the basis of in silico analysis (Figure 8).…”

The invertase gene family in plants is composed of two subfamilies of enzymes, namely, acid-and neutral/alkaline invertases (cytosolic invertase, CIN). Both can irreversibly cleave sucrose into fructose and glucose, which are thought to play key roles in carbon metabolism and plant growth. CINs are widely found in plants, but little is reported about this family. In this paper, a comparative genomic approach was used to analyze the CIN gene family in Solanum, including Solanum tuberosum, Solanum lycopersicum, Solanum pennellii, Solanum pimpinellifolium, and Solanum melongena. A total of 40 CINs were identified in five Solanum plants, and sequence features, phylogenetic relationships, motif compositions, gene structure, collinear relationship, and expression profile were further analyzed. Sequence analysis revealed a remarkable conservation of CINs in sequence length, gene number, and molecular weight. The previously verified four amino acid residues (D188, E414, Arg430, and Ser547) were also observed in 39 out of 40 CINs in our study, showing to be deeply conserved. The CIN gene family could be distinguished into groups α and β, and α is further subdivided into subgroups α1 and α2 in our phylogenetic tree. More remarkably, each species has an average of four CINs in the α and β groups. Marked interspecies conservation and collinearity of CINs were also further revealed by chromosome mapping. Exon-intron configuration and conserved motifs were consistent in each of these α and β groups on the basis of in silico analysis. Expression analysis indicated that CINs were constitutively expressed and share similar expression profiles in all tested samples from S. tuberosum and S. lycopersicum. In addition, in CIN genes of the tomato and potato in response to abiotic and biotic stresses, phytohormones also performed. Overall, CINs in Solanum were encoded by a small and highly conserved gene family, possibly reflecting structural and functional conservation in Solanum. These results lay the foundation for further expounding the functional characterization of CIN genes and are also significant for understanding the evolutionary profiling of the CIN gene family in Solanum.

“…For instance, reactive oxygen species (ROS) derived from normal cellular metabolism could oxidize bases and make DNA breaks [27]. In addition to DNA damage stress, other stress conditions, such as salt stress, are frequently encountered by all species [28]; therefore, the ability to adapt to external and internal stresses is important for the survival and proliferation of C. albicans in the human host. Our results show that CaPpt1 in C. albicans is required for cellular tolerance to NaCl-induced salt stress, cell wall stress (Calcofluor white) and DNA damage agents (MMS, HU and 4-NQO) (Fig.…”

To study the function of CaPpt1, we deleted PPT1 gene from the Candida albicans genome by sequentially replacing the entire coding region with the selectable markers ARG4 and HIS1. The results showed that the deletion of Ppt1 did not affect the hyphal formation of C. albicans under serum induction and caused enhanced sensitivity to DNA damage, Calcofluor white and saltinduced stress. We also found that Ppt1 was not required for the phenotypic response of cells treated with the genotoxins, methylmethane sulfonate and hydroxyurea. Flow cytometric analyses indicated that ppt1D cells and wild-type cells showed similar G 2 /M arrest profiles when exposed to DNA damage stress. Ppt1 was not required for the activation of the DNA damage response pathway, as indicated by normal phosphorylation of Rad53 and Rfa2 in ppt1D cells under DNA damage stress. We suggest that Ppt1 plays important roles in response to various stress conditions in C. albicans.
