Disease relevance of Genome, Plant

• Right 25 bp terminus sequence of the nopaline T-DNA is essential for and determines direction of DNA transfer from agrobacterium to the plant genome [1].
• Flanked by recombination sites from the bacteriophage P1 Cre/lox recombination system, the hpt gene was subsequently excised from the plant genome by the Cre recombinase [2].
• Two ylm homologues are also found in algal and plant genomes. cdv3 has low but significant similarity to divIVA, suggesting that minE and cdv3 both mediate division-site determination in cyanobacteria [3].

High impact information on Genome, Plant

• Genome analyses typically identify individual delangin or Nipped-B-like orthologs in diploid animal and plant genomes [4].
• NSF urged to increase plant genome sequencing effort [5].
• Plant genomes encode large numbers of receptor kinases that are structurally related to the tyrosine and serine/threonine families of receptor kinase found in animals [6].
• The plant genome also has 5-methylcytosine at CpG dinucleotides, which is maintained by METHYLTRANSFERASE1 (MET1), a homolog of Dnmt1 [7].
• Incorporation of the S1 fragment into plant genomes as well as its transcription was confirmed by PCR and RT-PCR analyses [8].

Chemical compound and disease context of Genome, Plant

• Plant signal molecules such as acetosyringone and certain monosaccharides induce the expression of Agrobacterium tumefaciens virulence (vir) genes, which are required for the processing, transfer, and possibly integration of a piece of the bacterial plasmid DNA (T-DNA) into the plant genome [9].

Biological context of Genome, Plant

• The octopine tumor-inducing (Ti) plasmid pTiA66 has an insertion mutation in its T region (the DNA region incorporated into the plant genome) that results in the slow growth of crown gall tumors [10].
• DNA sequence analysis of 29 cloned PCR products and of a maize retrotransposon cDNA confirmed the identity of these sequences as copia-like reverse transcriptase sequences, thereby demonstrating that this class of retrotransposons is a ubiquitous component of plant genomes [11].
• This can be interpreted as a consequence of a difference in mutation pressure related to spontaneous deamination of 5mC to thymine between the different compartments of plant genomes [12].
• Moreover, this elevated expansion rate of plant TF is not simply due to higher duplication rates of plant genomes but also to a higher degree of expansion compared to other plant genes [13].
• This paper describes expression profiles of the Arabidopsis HSP18.2 heat-shock gene promoter by using three different reporter genes, and the application of this promoter to a method we have developed to drive heat-shock-dependent transcription of plant genome DNA flanked by T-DNA insertions [14].

Anatomical context of Genome, Plant

• Based on the definition of these major and minor PTS and on the recognition of additional conserved properties, the accuracy of predicting peroxisomal proteins can be raised and plant genomes can be screened for novel proteins of peroxisomes more successfully [15].

Associations of Genome, Plant with chemical compounds

• Cyanobacterial and plant genomes encode proteins with some similarity to the folate and biopterin transporters of the trypanosomatid parasite Leishmania [16].
• We found that, in contrast with most known metazoan and plant genomes, splice signals contain, little information other than the canonical GT-AG dinucleotides [17].
• Intron-containing tRNA genes are exceptional within nuclear plant genomes [18].
• Stable integration of the genes into the plant genome was demonstrated by Southern analysis of DNA, isolated from hygromycin-resistant callus lines [19].
• It was shown that cytosine methylation at CpG dinucleotides and CpNpG trinucleotides occurred in all plant genomes examined [20].

Gene context of Genome, Plant

• Only unique homologs of SPO11 are found in animals and fungi whereas three distantly related SPO11 copies are present in plant genomes [21].
• To help resolve this conflict, we used parsimony and likelihood methods to analyze a 6, 095-character data set composed of four genes (chloroplast rbcL and small-subunit rDNA from all three plant genomes) from all major land plant lineages [22].
• This fusion has not been retained in plant genomes, which solely express unfused SCP-2 domains [23].
• Gene for proliferating-cell nuclear antigen (DNA polymerase delta auxiliary protein) is present in both mammalian and higher plant genomes [24].
• The virulence protein VirD2 of A. tumefaciens is tightly linked to the T-DNA and is thought to direct it to the plant genome [25].

Analytical, diagnostic and therapeutic context of Genome, Plant

• Six octopine tumour lines incited by pTiB6S3, pTiAch5 and pTiA6 on tobacco, Arabidopsis and Petunia were studied by the Southern blotting hybridisation technique in order to define accurately the dimensions of the segments of plasmid origin transferred to the tumourous cell and their organisation in the plant genome [26].
