1.	Anoxia (Hypoxia) 07/01/2013 - "To expand the annotation of genes with unknown function involved in the response of Arabidopsis to different environmental stress conditions, we selected 1007 such genes and tested the response of their corresponding homozygous T-DNA insertional mutants to salinity, oxidative, osmotic, heat, cold and hypoxia stresses. " 06/01/2010 - "Overexpression of RAP2.2 resulted in improved plant survival under hypoxia (low-oxygen) stress, whereas lines containing T-DNA knockouts of the gene had poorer survival rates than the wild type. " 01/01/2008 - "neoformans, we screened T-DNA insertional mutants for hypoxia-mimetic cobalt chloride (CoCl(2))-sensitive mutants. " 10/01/1992 - "The results obtained with reduced trypanothione at low concentrations suggest that radioprotection of t-DNA in hypoxia occurs predominantly by H atom donation and slightly by .OH radical scavenging, and the protection is greater than that by GSH or spermidine because the polyamine moiety in trypanothione allows a greater concentration of GSH near the DNA molecule."
2.	Infection 04/01/2013 - "In our current study, we characterized the response of a rice osrar1 T-DNA insertion mutant to infection by Magnaporthe oryzae, the causal agent of rice blast disease. " 06/01/2010 - "A panel of seven SR1 tobacco mutants (ATER1 to ATER7) derived via T-DNA activation tagging and screening for resistance to a microtubule assembly inhibitor, ethyl phenyl carbamate, were used to study the role of microtubules during infection and spread of tobacco mosaic virus (TMV). " 01/01/2015 - "To verify the effect of secreted factors, we exposed the plants to different Agrobacterium strains, including wild type (Ach5), its derivatives lacking vir genes, oncogenes or T-DNA, and the heat-killed form for 48 h post-infection; also, for a smaller set of strains, we examined the rates of three types of mutations at multiple time-points. " 01/01/2015 - "Agrobacterium infection, which is widely used to generate transgenic plants, is often accompanied by T-DNA-linked mutations and transpositions in flowering plants. " 01/01/2015 - "Overexpression of the RFA complex in tobacco resulted in decreased T-DNA expression, as determined by infection with A. "
3.	Neoplasms (Cancer) 03/01/1996 - "As these data correlate with earlier tumorigenesis studies, we propose that tumor suppression at higher temperatures results from a T-DNA transfer machinery which does not function properly." 05/01/2015 - "One of the T-DNA genes, 6b, can also by itself induce reprogramming of differentiated cells to generate tumors and is therefore recognized as an oncogene acting in plant cells. " 01/01/2014 - "Gene 6b in the T-DNA affects tumor morphology and this gene alone is able to induce small tumors on certain plant species. " 01/01/2013 - "Crown gall tumors develop after integration of the T-DNA of virulent Agrobacterium tumefaciens strains into the plant genome. " 10/01/2012 - "Agrobacterium tumefaciens is a soilborne pathogen that causes crown gall disease in many dicotyledonous plants by transfer of a portion of its tumor-inducing plasmid (T-DNA) into the plant genome. "
4.	Hypersensitivity (Allergy) 10/01/2015 - "In the present study, we isolated an Arabidopsis thaliana T-DNA insertion mutant that exhibited hypersensitivity to Zn depletion. " 01/01/2013 - "By combining sequence capture, next-generation sequencing and 2D-PCR pooling, we developed a new method that allowed the rapid localization of T-DNA insertion sites in 55 out of 64 mutant plants isolated in a screen for gyrase inhibition hypersensitivity. " 11/01/2012 - "Complementation test indicated that BnNAC5 could recover the defects such as salt-hypersensitivity and accelerated-leaf senescence of vni2 T-DNA insertion mutant. " 02/01/2011 - "Upon screening T-DNA mutants of DWD genes for ABA responses we obtained several candidates that exhibited ABA-hypersensitivity, and one was named DWA3 (DWD hypersensitive to ABA 3). " 07/01/2010 - "T-DNA insertion into the ZTP29 gene led to NaCl hypersensitivity in seed germination and seedling growth, leaf etiolation, and widening of cells in the root elongation zone. "
5.	Infertility (Sterility) 10/01/2012 - "The objectives of our study were to molecularly map the gene responsible for sterility in the soybean genome, to determine if the MSFS gene is a result of T-DNA insertion during Agrobacterium-mediated transformation, and to map the region that showed distorted segregation. " 12/01/2011 - "These analyses revealed that the aberrant growth and sterility phenotype of homozygous AtBT1::T-DNA mutants was complemented when expressing both the dual-targeted AtBT1 and AtBT1 specifically delivered to mitochondria. " 12/01/2011 - "It has been shown that homozygous AtBT1::T-DNA Arabidopsis mutants display an aberrant growth and sterility phenotype, and that AtBT1 is a carrier that is exclusively localized to the inner plastidial envelope and is required for export of newly synthesized adenylates into the cytosol. " 07/01/2009 - "Two independent alleles, designated pair3-1 and pair3-2, were identified in our T-DNA insertional mutant library which could not form bivalents due to failure of homologous chromosome pairing and synapsis at diakinesis, resulting in sterility in both male and female gametes. " 03/01/2005 - "Phenotypic analysis of the arp4-1 mutant allele, which has a T-DNA insertion in the promoter region and a moderate reduction in the level of AtARP4 protein expression, revealed partial sterility due to defects in anther development.
