Plant lodging resistance is an important integrative agronomic trait of grain yield and quality in crops. Although extensin proteins are tightly associated with plant cell growth and cell wall construction, little has yet been reported about their impacts on plant lodging resistance. In this study, we isolated a novel extensin-like (OsEXTL) gene in rice, and selected transgenic rice plants that...

To regulate levels of holophytochrome in a spatial-specific manner and investigate the major sites of action of phytochromes during seedling development, we constructed transgenic Arabidopsis (Arabidopsis thaliana) plant lines expressing plastid-targeted mammalian biliverdin IXalpha reductase (pBVR) under regulatory control of CAB3 and MERI5 promoters. Comparative photobiological and phenotypic...

Ginkgolides are key pharmaceutical components in Ginkgo biloba. Using the cDNA sequence of the MECP and MECT genes to design primers, we obtained the promoters of these genes from Ginkgo genomic DNA using the genome walking method. The two promoters were 744 and 982 bp in length, respectively. The cis-elements of the GbMECPs and GbMECT promoters were predicted and analyzed using the plant cis-a...

The roles of multiple promoters in the synthesis of rRNA under different conditions of growth were investigated, using two mycobacterial species as model organisms. When Mycobacterium smegmatis was grown under optimal conditions, its two rRNA operons contributed equally, with two promoters, one from each operon, being responsible for most transcripts. In stationary-phase growth or balanced grow...

Humic acids (HA) stimulate the growth of several plant species by regulating their hormonal and redox metabolisms. Nevertheless, studies on relationship with plant-associated microbiota are almost nonexistent. Here, we hypothesized that HA effect occurs in parallel regulation bacterial community. Rice was grown for 264 h nutrient solution supplied or not (80 mg L−1). Plant evaluated every 24 sa...

rosa hybrida l. is an important commercial cut flower. salicylic acid (sa) and calcium chloride (cacl2) act as endogenous signal molecules responsible for growth parameters in plants. the aim of this study was to evaluate the effects of preharvest sa and cacl2 treatments in extending the vase life of cut rose flowers. therefore, a factorial experiment based on completely randomized design with ...

Abstract Plants are sessile organisms that evolve with a flexible signal transduction system in order to rapidly respond environmental changes. Drought, common abiotic stress, affects multiple plant developmental processes especially growth. In response drought an intricate hierarchical regulatory network is established survive from the extreme environment. The transcriptional regulation carrie...

Coordinated transcriptional and metabolic reprogramming ensures a plant's continued growth and survival under adverse environmental conditions. Transcription factors (TFs) act to modulate gene expression through complex cis-regulatory element (CRE) interactions. Genome-wide analysis of known plant CREs was performed for all currently predicted protein-coding gene promoters in grapevine (Vitis v...
