Genetic regulation of time to flower in Arabidopsis thaliana.
نویسنده
چکیده
In Arabidopsis thaliana, the initiation of flowering is carried out by four genetic pathways: gibberellin, autonomous, vernalization, and light-dependent pathways. These processes are integrated by the function of the genes FD, FE, FWA, PDF2, SOC1, and FT at the integration pathway. The integrated signal of the floral induction is transmitted to the floral meristem identity genes LFY and AP1, and floral morphogenesis is performed.

Differential Expression of Arabidopsis thaliana Acid Phosphatases in Response to Abiotic Stresses
The objective of this research is to identify Arabidopsis thaliana genes encoding acid phosphatases induced by phosphate starvation. Multiple alignments of eukaryotic acid phosphatase amino acid sequences led to the classification of these proteins into four groups including purple acid phosphatases (PAPs). Specific primers were degenerated and designed based on conserved sequences of PAPs isol...

Arabidopsis thaliana is a suitable model plant for genetic and molecular biology studies in higher plants. However, its hydroponic culture for biochemical and physiological studies is a challenge due to small size, capillary roots and little biomass at maturity. Several cultural systems have been suggested for Arabidopsis thaliana hydroponic culture, each having special advantages and disadvant...
متن کاملGene transcriptomic profile in arabidopsis thaliana mediated by radiation-induced bystander effects
Background: The in vivo radiation-induced bystander effects (RIBE) at the developmental, genetic, and epigenetic levels have been well demonstrated using model plant Arabidopsis thaliana (A. thaliana). However, the mechanisms underlying RIBE in plants are not clear, especially lacking a comprehensive knowledge about the genes and biological pathways involved in the RIBE in plants. Materials and...
متن کاملGA4 Is the Active Gibberellin in the Regulation of LEAFY Transcription and Arabidopsis Floral Initiation W
Flower initiation in Arabidopsis thaliana under noninductive short-day conditions is dependent on the biosynthesis of the plant hormone gibberellin (GA). This dependency can be explained, at least partly, by GA regulation of the flower meristem identity gene LEAFY (LFY) and the flowering time gene SUPPRESSOR OF CONSTANS1. Although it is well established that GA4 is the active GA in the regulati...

SETH4 coding sequence with 2013 bp is a member of gene family expressed in gametophytic tissues of Arabidopsis thaliana. This fragment was PCR amplified using Kod Hi Fi DNA polymerase enzyme. This fragment was cloned into pGBKT7 bate vector and transformed E. coli DH5? cells containing vector were selected on LB medium containing Kanamycin. Finally, pGBKT7-SETH4 bate was transformed into yeast ...
