Auto‐Downregulation of the Florigen FT Production Prevents Precocious Flowering in Plants

open access: yesAdvanced Science, EarlyView.
This study shows that the leaf vein‐expressed FD complexes with the florigen FT to bind DNA motifs in FT promoter, which antagonizes CONSTANS‐mediated FT activation to feedback down‐regulate FT expression. This prevents an excessive induction of FT expression by inductive photoperiods, thereby precluding precocious transition to flowering in ...

Identification and characterisation of behavioural genes of agrobacterium tumefaciens. [PDF]

open access: yes, 2000
Three behavioural mutants (fla-8, mot-6 and cheL) generated by transposon Tn5 mutagenesis and localised on cosmid pDUB1905 were studied. The cosmid pDUB1905, from a representative genomic library of the Agrobacterium tumefaciens C58C1 chromosome has ...

Molecular Identification of Gall-forming Bacteria in Stone and Pome Fruits using the recA Gene Sequence [PDF]

open access: yesپژوهش‌های حفاظت گیاهان ایران
IntroductionCrown gall is an economically important plant disease that affects dicotyledonous and a few monocotyledonous plants in orchards, farms, and nurseries, worldwide. The disease is caused by Agrobacterium tumefaciens (Smith & Townsend, 1907) Conn

Dual Cytoplasmic and Chloroplastic Mechanisms Fine‐Tune Chloroplast Division through ARC3 Protein Stability

open access: yesAdvanced Science, EarlyView.
ARC3 levels are controlled by cytosolic and chloroplast proteolytic systems. PUB52 mediates ARC3 precursor ubiquitination and degradation in the cytosol, while CLPC1 promotes ARC3 degradation in chloroplasts, where ARC2 protects ARC3 from excessive breakdown. Disrupting these components causes chloroplast division defects, placing them upstream of ARC3.

Heterologous expression from Agrobacterium virulence promoters [PDF]

open access: yes, 1991
The aim of this work was twofold: to construct plasmids with a gene encoding a pesticidal protein expressed from an Agrobacterium tumefaciens virulence promoter and to determine, in planta, the sites of Agrobacterium vir-induction.

Transformation of HBsAg (hepatitis B surface antigen) gene into tomato mediated by Agrobacterium tumefaciens

open access: yesCzech Journal of Genetics and Plant Breeding, 2011
The plant expression vector pBRSAg was constructed as suitable for transformation via Agrobacterium-mediated approach. It contains all elements for plant expression, such as CaMV 35S promoter, both left and right border sequence for transferred DNA (T ...

Transposase‐Assisted Donor Tethering Boosts Large‐Fragment HDR in Plants

open access: yesAdvanced Science, EarlyView.
A transposase‐assisted donor tethering strategy is developed to enhance homology‐directed repair in plants. By recruiting donor DNA to double‐strand breaks and synergizing with repair pathway reprogramming and transcription‐coupled donor design, this system markedly improves large‐fragment targeted insertion efficiency, providing a robust platform for ...

Investigating the role of chemotaxis operon genes in agrobacterium tumefaciens [PDF]

open access: yes, 2003
A 1.7 Kb chromosomal DNA of A. tumefaciens C58C1 downstream of chemotaxis operon was sequenced completely in both directions. The comparison of this sequence with sequence databases revealed one open reading frame with strong sequence identity to MCP ...

Characterization and host range of five tumorigenicAgrobacterium tumefaciens strains and possible applicationin plant transient transformation assays [PDF]

open access: yes, 2014
Agrobacterium tumefaciens is a Gram-negative bacterium. It causes plants to produce crown gall disease because of the transfer, integration and expression of oncogenes encoded by the T-DNA (transferred DNA) region of the tumour-inducing (Ti) plasmid.

Plasmid required for virulence of Agrobacterium tumefaciens [PDF]

open access: yesJournal of Bacteriology, 1975
The irreversible loss of crown gall-inducing ability of Agrobacterium tumefaciens strain C-58 during growth at 37 C is shown to be due to loss of a large plasmid (1.2 X 10-8 daltons). The gene responsible for this high rate of plasmid loss at elevated temperatures seems to be located on the plasmid. In addition, another spontaneous avirulent variant, A.
