“…Transcription factors (TFs) play important roles in regulating of different genes to the response to stress and in coordinating developmental regulation (Mizoi et al 2012;Rushton et al 2012). Plant-specific ERF family proteins are well-known to improve the tolerance to abiotic stresses such as high salinity, cold, drought, disease or excess water, and to adapt to various environmental conditions (Mizoi et al 2012;Rehman and Mahmood 2015;Thirugnanasambantham et al 2015). The best-known ERF family members are Dehydration Responsive Element Binding1 (DREB1/CBF) and DREB2 genes (Sakuma et al 2002).…”

RELATED TO AP2.12 (RAP2.12) is one of the Ethylene Response Factors (ERF) transcription factor and plays a key role in controlling plant root bending and responding to multiple abiotic stresses including hypoxia stress. In this study, FmRAP2.12 gene was isolated and characterized from Fraxinus mandshurica Rupr. The open reading frame (ORF) of FmRAP2.12 was 1170 bp and encoded a protein of 389 amino acids. The conserved domains, three-dimensional phylogenetic relationship of FmRAP2.12 was also investigated. Quantitative real-time (qRT-PCR) analyzed the expression of FmRAP2.12 in different tissues. The expression level of FmRAP2.12 was highest in roots followed by leaves, and lowest in male flowers. Abiotic stress and hormone signal-induced expression was established using qRT-PCR. Salt stress induced FmRAP2.12 to a double peak pattern: the first peak value was at 6 h and the second at 72 h. Drought stress also induced FmRAP2.12 to a double peak pattern: the first at 6 h and the second at 48 h. FmRAP2.12 was up-regulated after initiation of gibberellic acid (GA3) treatment, with a one peak pattern at 24 h. FmRAP2.12 may not respond to cold stress and Abscisic acid (ABA) treatment. The transient overexpression of FmRAP2.12 caused the up-expression of downstream key genes of abiotic stress response and gibberellin pathway. Our research reveals the molecular characteristic and expression patterns under abiotic stress and hormone condition of FmRAP2.12, providing support for the genetic improvement of F. mandshurica at a molecular level.

“…Plant stress-tolerance is regulated through a network of signal transduction pathways, some of which may converge on ERF proteins through complex interactions (Zhang et al, 2004; Rehman and Mahmood, 2015). For example, AtERF4 is thought to be a key factor in the regulation of ET/ABA-dependent defense pathways and could modulate the transcription of many ET/ABA-dependent defense genes (Yang et al, 2005); GmERF3 may connect the ET, JA, and SA signaling pathways, which mediate biotic and abiotic stress responses (Zhang et al, 2009); Dong (2001) determined that two well-defined signaling pathways involved in pathogen-defense responses make use of the plant hormones SA or ET/JA, respectively; Kamsvågmagnusson et al (2014) also reported that the expression of genes encoding ERFs is regulated in both an ET-dependent and -independent manner; while jasmonates (JAs) also play central signaling roles, using MeJA as an elicitor, in a wide range of plant resistance responses (Thagun et al, 2016). Our present study demonstrated that levels of GmERF113 mRNA transcripts were significantly enhanced by P. sojae , ET, and MeJA stress; however, the observed changes elicited in response to SA and ABA stress were relatively minor.…”

Phytophthora root and stem rot of soybean caused by the oomycete Phytophthora sojae, is a destructive disease worldwide. Ethylene response factors (ERFs) play important roles in regulating plant biotic and abiotic stress tolerance. In this study, a new ERF gene, GmERF113, was isolated from the highly resistant soybean ‘Suinong 10.’ Sequence analysis suggested that the protein encoded by GmERF113 contained a conserved AP2/ERF domain of 58 amino acid and belonged to the B-4 subgroup of the ERF subfamily. Expression of GmERF113 was significantly induced by P. sojae, ethylene, and methyl jasmonate. GmERF113 protein localized to the nucleus when transiently expressed in Arabidopsis protoplasts, could bind to the GCC-box, and acted as a transcription activator. In addition, a region of the full-length GmERF113, GmERF113-II, interacted with a basic helix-loop-helix transcription factor (GmbHLH) in yeast cells. Full-length GmERF113 also interacted with GmbHLH in planta. GmERF113-overexpressing transgenic plants in susceptible cultivar ‘Dongnong 50’ soybean exhibited increased resistance to P. sojae and positively regulated the expression of the pathogenesis-related genes, PR1 and PR10-1. These results indicate that GmERF113 may play a crucial role in the defense of soybean against P. sojae infection.

“…The two morphs may have different genes expressed in response to stress or one morph may have a stronger response to stress than the other. Some of the DE genes involved in stress response are influenced by hormones known to be involved in this type of process, including ethylene and abscisic acid, and these genes include various ethylene-responsive transcription factors, abscisic acid receptor pyr1-like, and others (Thirugnanasambantham et al, 2015; Wang et al, 2015) (Table 7). Future research can investigate variation in hormones or hormone response between morphs, which may influence the observed morph-specific responses to stress.…”

Genes controlling the morphological, micromorphological, and physiological components of the breeding system distyly have been hypothesized, but many of the genes have not been investigated throughout development of the two floral morphs. To this end, the present study is an examination of comparative transcriptomes from three stages of development for the floral organs of the morphs of Lithospermum multiflorum. Transcriptomes of flowers of the two morphs, from various stages of development, were sequenced using an Illumina HiSeq 2000. The floral transcriptome of L. multiflorum was assembled, and differential gene expression (DE) was identified between morphs, throughout development. Additionally, Gene Ontology (GO) terms for DE genes were determined. Fewer genes were DE early in development compared to later in development, with more genes highly expressed in the gynoecium of the SS morph and the corolla and androecium of the LS morph. A reciprocal pattern was observed later in development, and many more genes were DE during this latter stage. During early development, DE genes appear to be involved in growth and floral development, and during later development, DE genes seem to affect physiological functions. Interestingly, many genes involved in response to stress were identified as DE between morphs.
