“…Only the biological processes were used for GO term analysis Table 1 Annotation of genes up-regulated or down-regulated in AsHSP26.8a overexpressing transgenic (TG) Arabidopsis compared to wild type (WT) controls. Significant differences were corrected with FDR < 0.01 and expression ratio ≥ 2, (FC, fold change) Overexpression of CmERF053 of chrysanthemum could enhance drought tolerance [102]. In Tamarix hispida, constitutive expression of an ERF transcription factor, ThCRF1, increased biosynthesis of trehalose and proline and the activities of SOD and POD, resulting in an altered osmotic potential and an enhanced reactive oxygen species (ROS) scavenging, and therefore significantly improved salt tolerance in transgenic plants.…”

Background: Small heat shock proteins (sHSPs) are critical for plant response to biotic and abiotic stresses, especially heat stress. They have also been implicated in various aspects of plant development. However, the acting mechanisms of the sHSPs in plants, especially in perennial grass species, remain largely elusive. Results: In this study, AsHSP26.8a, a novel chloroplast-localized sHSP gene from creeping bentgrass (Agrostis stolonifera L.) was cloned and its role in plant response to environmental stress was studied. AsHSP26.8a encodes a protein of 26.8 kDa. Its expression was strongly induced in both leaf and root tissues by heat stress. Transgenic Arabidopsis plants overexpressing AsHSP26.8a displayed reduced tolerance to heat stress. Furthermore, overexpression of AsHSP26.8a resulted in hypersensitivity to hormone ABA and salinity stress. Global gene expression analysis revealed AsHSP26.8a-modulated expression of heat-shock transcription factor gene, and the involvement of AsHSP26.8a in ABA-dependent and-independent as well as other stress signaling pathways. Conclusions: Our results suggest that AsHSP26.8a may negatively regulate plant response to various abiotic stresses through modulating ABA and other stress signaling pathways.

“…The poplar gene EBB1 is known to encode an AP2/ERF transcription factor; plants over-expressing it exhibit early budbreak and those under-expressing it suffer from delayed budbreak [45]. The chrysanthemum ERF transcription factor CmERF053 has been shown to regulate shoot branching [46], while the product of the Larix kaempferi AP2/ERF gene LkAP2L2 exerts a pleiotropic effect on both branching and seed development [47]. The A. thaliana gene EBE encodes an AP2/ERF transcription factor, which has a notable effect on shoot architecture [48].…”

Background: Producers of cut flower chrysanthemum are obliged to manually remove lateral buds, a procedure which consumes one third of the total production cost. The formation of lateral buds in 'SEI NO ISSEI' is suppressed when the plants are exposed to high temperatures, but the molecular basis of this phenomenon is not well understood. Here, the transcriptome of buds formed by decapitated chrysanthemum plants grown under a high temperature regime was characterized with a view to revealing which genes known to be involved in a pathway determining shoot branching were induced/repressed by the treatment. Results: The transcriptomic data was acquired using RNA-Seq technology, based on the Illumina HiSeq™ 2000 platform. Four libraries were generated from pooled lateral buds of decapitated 'SEI NO ISSEI'. To predict the potential functions of unigenes in the 'SEI NO ISSEI' buds, after assembly, we performed seven functional database annotations. 132,396 unigenes were assembled, of which 79,116 unigenes were annotated in the seven functional databases. The percentage of unigenes annotated in the NR, NT, Swiss-Prot, KEGG, COG, Interpro, and GO databases were 54.59%, 42.96%, 39.05%, 41.84%, 20.72%, 37.25%, and 13.01%, respectively. Multiple differentially expressed transcription factors and auxin-related genes were identified in buds of decapitated 'SEI NO ISSEI' under 28°C/23°C or 38°C/33°C. Constitutively expressing CmERF110 in wild type Arabidopsis thaliana produced a bushy plant. A quantitative analysis of gene expression changes in the CmERF110 transgenic A. thaliana plants showed that the presence of the transgene altered the abundance of transcript produced by TIR1, ARF2, ARF16, IAA3 and IAA9 (encoding auxin signaling proteins) and PIN1, AUX1, LAX1, LAX2 and ABCB1 (auxin transport). Conclusions: This study reported a highly complete transcriptome from the buds of decapitated 'SEI NO ISSEI'. Differential abundant transcripts during high temperature treatments were identified and validated by qPCR, many of these differentially abundant transcripts as key players in bud outgrowth. These include known members of the AP2/ERF, MYB, WRKY, bHLH families and auxin-related genes. CmERF110 regulated shoot branching when its encoding gene was heterologously expressed in A. Thaliana. The regulation acted through the auxin-related genes. Background 4 The ability of the plant shoot to form branches has a major effect on the plant's architecture, a trait of major importance in the context of crop domestication and improvement [1, 2]. Axillary meristems are composed of a group of cells which have retained their meristematic potential [3]. Following their initiation, these structures develop into axillary buds, which either remain dormant or develop into a new branches, depending a number of both internal and/or external cues [4]. Three forms of bud dormancy have been recognized: paradormancy occurs when growth ceases because of physiological factors external to the bud; endodormacy when growth is regulated by internal physiologi...

“…Many studies have proved that plant root development could be regulated by ERF [40], WRKY [41,42], bHLH [43][44][45], MYB and MYB-like [46][47][48][49], NAC [50,51], AP2 [52,53] as well as MADS-box [54,55] TF genes.

Background: To explore the effects and molecular mechanism of graphene on the growth and development of Zea mays L., the seeds were randomly divided into the control and experimental groups in this study, the roots of Zea mays L. seedlings were watered by different concentrations (0~100 mg/L) graphene. Results: By evaluating the root growth indices of maize, 50 mg/L graphene increased significantly the total root length, root volume, the number of root tips and root forks of maize seedlings compared with the control group. The contents of nitrogen and potassium in the soil around the roots were elevated after the treatment of 50 mg/L graphene. Then, we compared the transcriptome changes of Zea mays roots in response to 50 mg/L graphene treatment. Transcriptional factor regulation, plant hormone signal transduction, nitrogen and potassium metabolism as well as secondary metabolism in maize roots subjected to graphene showed significant up-regulated expressions, all of which might be related to mechanisms underlying graphene response. Based on qPCR validations, we proposed several candidate genes that might be responded to the graphene treatment in maize roots. Conclusion: The transcriptional profiles presented here provide a foundation for deciphering the mechanism between the graphene and maize roots interaction.
