Promoters are the important regulation factors/elements in gene expression. In this paper, the structure and function of promoters are analyzed and reviewed. Plant gene promoters are classified into constitutive promoters, inducible promoters, tissue (spatial) and developmental (temporary) specific promoters. The bi-directional promoters existed in nature and reconstructed artificially by some strategies are introduced and their applications in plant genetic engineering are prospected.

In the present study, the taxonomic position of Salinisphaera halophila (NZ_AYKF00000000) and Salinisphaera orenii (NZ_AYKH00000000) was re-evaluated. In addition, their metabolic potentials and mechanisms for mitigating stress conditions were determined. Comparisons of 16S rRNA gene sequences, analysis of the phylogenetic tree, phylogenomic tree, average nucleotide identity (ANI), and digital DNA-DNA hybridization (dDDH) values were conducted.

Despite years of progress in biotechnology, altering the genetic makeup of many plant species, especially their plastids, remains challenging. The existence of a cell wall poses a significant obstacle to the effectual transportation of biomolecules. Developing efficient methods to introduce genes into plant cells and organelles without causing harm is an ongoing area of research.

Phytoglobin1 promotes Arabidopsis somatic embryogenesis through the mediation of ethylene and the ERFVII HRE2. Generation of somatic embryos in Arabidopsis (Arabidopsis thaliana) is a two-step process, encompassing an induction phase where embryogenic tissue (ET) is formed followed by a developmental phase encouraging the growth of the embryos. Using previously characterized transgenic lines dysregulating the class 1 Phytoglobin (Pgb1) we show that suppression of Pgb1 decreases somatic embryogenesis (SE).

Plant breeding needs to embrace genetic innovations to ensure stability in crop yields under fluctuating climatic conditions. Development of commercial hybrid varieties has proven to be a sustainable and economical alternative to deliver superior yield, quality and resistance with uniformity in a number of food crops. Cytoplasmic male sterility (CMS), a maternally inherited inability to produce functional pollen, facilitates a three-line system for efficient hybrid seed production strategies in crops.

Production of secreted leaf bud resin is a mechanism for temperate trees to protect dormant leaf buds against frost damage, dehydration, and insect herbivory. Bud resins contain a wide variety of special metabolites including terpenoids, benzenoids, and phenolics. The leaf bud resins of Populus trichocarpa and P.
