Abstract
AP2/ERF transcription factor genes play an important role in regulating the responses of plants to various abiotic stresses, such as cold, drought, high salinity, and high temperature. However, less is known about the function of oil palm AP2/ERF genes. We previously obtained 172 AP2/ERF genes of oil palm and found that the expression of EgAP2.25 was significantly up-regulated under salinity, cold, or drought stress conditions. In the present study, the sequence characterization and expression analysis for EgAP2.25 were conducted, showing that it was transiently over-expressed in Nicotiana tabacum L. The results indicated that transgenic tobacco plants over-expressing EgAP2.25 could have a stronger tolerance to salinity stress than wild-type tobacco plants. Compared with wild-type plants, the over-expression lines showed a significantly higher germination rate, better plant growth, and less chlorophyll damage. In addition, the improved salinity tolerance of EgAP2.25 transgenic plants was mainly attributed to higher antioxidant enzyme activities, increased proline and soluble sugar content, reduced H2O2 production, and lower MDA accumulation. Furthermore, several stress-related marker genes, including NtSOD, NtPOD, NtCAT, NtERD10B, NtDREB2B, NtERD10C, and NtP5CS, were significantly up-regulated in EgAP2.25 transgenic tobacco plants subjected to salinity stress. Overall, over-expression of the EgAP2.25 gene significantly enhanced salinity stress tolerance in transgenic tobacco plants. This study lays a foundation for further exploration of the regulatory mechanism of the EgAP2.25 gene in conferring salinity tolerance in oil palm.

Abstract
One of the strategies to overcome diseases or abiotic stress in crops is the use of improved varieties. Genetic improvement could be accomplished through different methods, including conventional breeding, induced mutation, genetic transformation, or gene editing. The gene function and regulated expression through promoters are necessary for transgenic crops to improve specific traits. The variety of promoter sequences has increased in the generation of genetically modified crops because they could lead to the expression of the gene responsible for the improved trait in a specific manner. Therefore, the characterization of the promoter activity is necessary for the generation of biotechnological crops. That is why several analyses have focused on identifying and isolating promoters using techniques such as reverse transcriptase-polymerase chain reaction (RT-PCR), genetic libraries, cloning, and sequencing. Promoter analysis involves the plant genetic transformation method, a potent tool for determining the promoter activity and function of genes in plants, contributing to understanding gene regulation and plant development. Furthermore, the study of promoters that play a fundamental role in gene regulation is highly relevant. The study of regulation and development in transgenic organisms has made it possible to understand the benefits of directing gene expression in a temporal, spatial, and even controlled manner, confirming the great diversity of promoters discovered and developed. Therefore, promoters are a crucial tool in biotechnological processes to ensure the correct expression of a gene. This review highlights various types of promoters and their functionality in the generation of genetically modified crops.

Abstract
The Translationally Controlled Tumor Protein (TCTP) is a conserved protein which expression was associated with several biochemical and cellular functions. Loss-of-function mutants are lethal both in animals and in plants, making the identification of its exact role difficult. Recent data using the model plant Arabidopsis thaliana provided the first viable adult knockout for TCTP and helped addressing the biological role of TCTP during organ development and the functional conservation between plants and animals. This chapter summarizes our up to date knowledge about the role of TCTP in plants and discuss about conserved functions and mechanisms between plants and animals.

Abstract
We have characterized four novel constitutive promoters ARP1, H3F3, HSP and H2BF3 that are active in all tissues/stages of transgenic plants and stable over two homozygous generations. Gene promoters that are active and stable over several generations in transgenic plants are valuable tools for plant research and biotechnology. In this study, we characterized four putative constitutive promoters (ARP1, H3F3, HSP and H2BF3) in transgenic rice plants. Promoter regions were fused to the green fluorescence protein (GFP) reporter gene and transformed into rice. Single-copy transgenic lines were then selected and promoter activity was analyzed in various organs and tissues of two successive homozygous generations. All four promoters showed a broad expression profile in most tissues and developmental stages, and indeed the expression of the ARP1 and H3F3 promoters was even greater than that of the PGD1 promoter, a previously described constitutive promoter that has been used in transgenic rice. This observation was based on expression levels in leaves, roots, dry seeds and flowers in both the T2 and T3 generations. Each promoter exhibited comparable levels of activity over two homozygous generations with no sign of transgene silencing, which is an important characteristic of promoters to be used in crop biotechnology applications. These promoters therefore have considerable potential value for the stable and constitutive expression of transgenes in monocotyledonous crops.

Abstract
Oil palm is a major economic crop for Malaysia. The major challenges faced by the industry are labor shortage, availability of arable land and unstable commodity price. This has caused the industry to diversify its applications into higher value products besides increasing its yield. While conventional breeding has its limitations, biotechnology was identified as one of the tools for overcoming the above challenges. Research on biotechnology of oil palm began more than two decades ago leveraging a multidisciplinary approach involving biochemical studies, gene and promoter isolation, transformation vector construction and finally genetic transformation to produce the targeted products. The main target of oil palm biotechnology research is to increase oleic acid in the mesocarp. Other targets are stearic acid, palmitoleic acid, ricinoleic acid, lycopene (carotenoid) and biodegradable plastics. Significant achievements were reported for the biochemical studies, isolation of useful oil palm genes and characterization of important promoters. A large number of transformation constructs for various targeted products were successfully produced using the isolated oil palm genes and promoters. Finally transformation of these constructs into oil palm embryogenic calli was carried out while the regeneration of transgenic oil palm harboring the useful genes is in progress.

Abstract
A plant-derived 0.3 kb constitutive promoter was obtained from AtTCTP expression analysis, and successfully applied to the expression of a selectable marker gene for production of transgenic creeping bentgrass plants. The isolation and use of an efficient promoter is essential to develop a vector system for efficient genetic transformation of plants, and constitutive promoters are particularly useful for the expression of selectable marker genes. In this study, we characterized a small size of the constitutive promoter from the expression analysis of Arabidopsis thaliana translationally controlled tumor protein (AtTCTP) gene. Histochemical and fluorometric GUS analyses revealed that a 303 bp upstream region from the start codon of the AtTCTP gene showed strong GUS expression throughout all plant tissues, which is approximately 55 % GUS activity compared with the cauliflower mosaic virus 35S promoter (35Spro). To examine the possible application of this promoter for the development of genetically engineered crops, we introduced pCAMBIA3301 vector harboring the 0.3 kb promoter of AtTCTP (0.3kbpro) that was fused to the herbicide resistance BAR gene (0.3kb pro ::BAR) into creeping bentgrass. Our transformation results demonstrate that transgenic creeping bentgrass plants with herbicide resistance were successfully produced using 0.3kb pro ::BAR as a selectable marker. Northern blot analysis revealed that the transgenic plants with 0.3kb pro ::BAR showed reduced but comparable expression levels of BAR to those with 35S pro ::BAR. Moreover, the transcription activity of the 0.3 kb promoter could be increased by the fusion of an enhancer sequence. These results indicate that the 0.3 kb AtTCTP promoter can be used as a plant-derived constitutive promoter for the expression of selectable marker genes, which facilitates its use as an alternative to the 35S promoter for developing genetically engineered crops.
