As a family of transcription factors, DNA binding with one figure (Dof) proteins play important roles in various biological processes in plants. Here, a total of 60 putative apple (Malus domestica) Dof genes (MdDof) were identified and mapped to different chromosomes. Chromosomal distribution and synteny analysis indicated that the expansion of the MdDof genes came primarily from segmental and duplication...
The RNA-Seq platform was used to characterize the high-temperature stress response of Chrysanthemum nankingense. A set of 54,668 differentially expressed unigenes was identified. After a threshold of ratio change ≥2 and a q-value of <0.05 were applied, the number of differentially transcribed genes was reduced to 3955, of which 765 were up-regulated and 3190 were down-regulated in response to heat...
Transcriptional regulation in response to environmental challenges is crucial for survival of many organisms. In this study, we characterized structural and functional properties of CgAP1, a Saccharomyces cerevisiae YAP1 ortholog, which encodes a transcription factor involved in various stress responses. Deletion of CgAP1 led to decreased resistance to hydrogen peroxide, 4-nitroquinoline-N-oxide (4-NQO),...
Diapause prepares insects and other arthropods to survive in harsh environments. To explore the molecular basis of winter (WD) and summer diapauses (SD), we screened for diapause-specific genes in the onion maggot, Delia antiqua, that diapauses as a pupa in both summer and winter. A diapause-induced transcript, DaTrypsin, was identified through differential display, and examined by Northern blot,...
Here, we report the identification and characterization of a new hsp40 family member, heat shock cognate 40 (hsc40), which may be a specific functional partner for hsc70. The hsc40 gene consists of five exons and four introns. The previously characterized hsp40 gene contains only three exons and two introns. Despite this difference in the numbers of exons and introns, the structures of these two genes...
