N6549 Name: spr2-2 Price: £11.00
Donor
  • Nara Institute of Science and Technology (NAIST) Takashi Hashimoto
Locus Stock type: individual line
Material type: seed


Phenotype
Defective in directional cell elongation processes; abnormal cortical microtubule function; exhibits right-handed helical growth in longitudinally expanding organs such as roots, etiolated hypocotyls, stems, petioles, and petals; twisting phenotype is most apparent in lateral organs (cotyledons, rosette leaves, and petals), when the plant is viewed from above, these organs are twisted in a counterclockwise direction; the counterclockwise twisting of rosette leaves and cotyledones is caused by right-handed helical growth of epidermal cell files in petioles; epidermal cell files of hypocotyl and stem in dark-grown plants also form constitutive right-handed helices; allelic to two classic twisting mutants, tortifolia1 and convoluta.

Locus Stock type: individual line
Material type: seed


Description
confirmed line isolated from original SALK line SALK_004521; homozygous for the insertion
Phenotype
Defective in gibberellin 3-oxidase 1; involved in the production of bioactive GA for vegetative and reproductive growth and development; semi-dwarf plants with a 50% reduction in final height and a slightly reduced rosette size compared with wild type; roots are slightly shorter; germination percentages are similar to wild type in either the dark or the light; plants have the same number of leaves as wild type, but they flower 3 days later than wild type; no observable plant phenotype was noted in the flowers and the fertility (average number of seeds/silique on primary inflorescence stems). Relatively high levels of expression in all organs and stages of plant development; predominantly expressed in the stem, consistent with the requirement of bioactive GA for stem elongation and the semi-dwarf phenotype; expressed at relatively high levels in the cortex and endodermis of the embryo axis of germinating seeds; expressed in roots of 5-dayold seedlings; the bioactive level of GA4 in plants is decreased , while the level of GA9 is increased compared to wild type.
N6944 Name: ga3ox1/ga3ox2 Price: £11.00
Donor
  • Duke University Tai-ping Sun
Stock type: individual line
Material type: seed


Description
Double mutant generated by genetic crossing between ga3ox1-3 and ga3ox2-1; severe defect in seed germination and root growth; dwarf plants; severe root length growth phenotype similar to the ga1-3 mutant; reduced ability of seeds to germinate, in contrast to each single mutant, double mutant seeds fail to germinate in the dark and had only a 5% germination frequency in the light, this slight leakiness in germination of the double mutant is similar to the ga1-3 mutant; plants have the same number of leaves as wild type, but flowering is delayed for 7 days; no observable plant phenotype was noted in the flowers and the fertility (average number of seeds/silique on primary inflorescence stems). Although the ga3ox2 single mutant does not have any phenotype, plants are 30% smaller in leaf diameter and 37% shorter than ga3ox1; therefore, production of bioactive GA by GA3ox2 during early vegetative growth may be sufficient for transport to the stem to induce the partial stem elongation observed in the ga3ox1 mutant, the overall phenotype of the double mutant is consistent with expression patterns of these two genes. The bioactive level of GA4 is severely decreased; while the level of GA9 is drastically increased, compared to wild type plants; exogenous application of GA4, but not GA9, was able to induce seed germination in a dose-dependent manner.

Description
A line homozygous for the shoot apical meristem-expressed PSTM:GUS reporter (the promoter of the SHOOT MERISTEMLESS gene fused to beta-glucuronidase) was mutagenized with ethyl methanesulfonate and screened for embryo-defective mutants.
Phenotype
Weak allele. Embryos have altered placement of the root pole, slow embryonic development, longer cell cycles (~35%) and larger cells. Abnormal division of the hypophysis in the developing root of the embryo, generating a lens cell that is abnormal in shape or abnormally positioned; asymmetric development of the provasculature, this ultimately leads to an abnormal root pole which is displaced laterally causing the root-shoot axis to be at an angle to the long axis of the suspensor, giving the embryo a tilted appearance. Embryos are viable, have larger cells and nuclei than wild-type embryos but the same DNA content, mutant embryos are larger than wild-type embryos at the same developmental stage. Plants have slow growing roots, slightly delayed flowering, altered floral phyllotaxis, reduced number of ovules, abnormally developing ovules, and reduced fertility.

Description
Knockout line harboring a T-DNA insertion in intron 2 (at 506 bp) of the GCR1 gene, was found in a PCR screen of a collection of 72,960 T-DNA-inserted Arabidopsis lines (Arabidopsis Knockout Facility, University of Wisconsin, BASTA population) using a GCR1-specific primer and a T-DNA left border-specific primer; homozygous mutant line for At1g 48270 (GCR1 gene).
Phenotype
Plants exhibit hypersensitivity to abscisic acid (ABA) in assays of root growth, gene regulation, and stomatal response. Root growth of seedlings is markedly more sensitive to inhibition by ABA compared with wild-type. Plants have enhanced drought tolerance and lower rates of water loss (lower transpiration rates). Plants are hypersensitive to ABA and S1P regulation of stomatal responses: guard cells are hypersensitive to both inhibition of opening of preclosed stomata and promotion of closure of preopened stomata by ABA; plants respond to the lipid metabolite, sphingosine-1-phosphate (S1P), in an identical fashion as they do to ABA: guard cells are hypersensitive to S1P-induced inhibition of stomatal opening and S1P-induced promotion of stomatal closure compared with the wild-type.

Description
recessive mutant
Phenotype
Plants exhibit reduced lateral shoot meristems (LSMs) of rosette and cauline leaves, meristem-defective flowers, altered leaf morphology (size and shape) and leaf color. The percentage of absent LSMs is correlated with the severity of leaf morphology and color, the severity of leaf morphology and color is also correlated with the % of meristem-defective flowers; however, the % of absent LSMs is independent of the % of meristem-defective flowers.

Donor
  • University of Michigan Steven Clark
Locus Stock type: individual line
Material type: seed


Description
recessive mutant
Phenotype
Plants exhibit reduced lateral shoot meristems (LSMs) of rosette and cauline leaves; approximately 70% of cauline leaves lack a lateral meristem and 16% fail to produce meristems in the axils of any rosette leaves; decapitation of the primary shoot meristem (SAM) fails to stimulate axillary meristem formation; in the place of axillary meristems, the axils of affected leaves are usually bare, but occasionally develop a differentiated structure that is a leaf or a filamentous structure. Reduced flower meristem activity, while the majority of the flowers develop normally, 12% of the flowers initiate only a limited set of flower organs and appear to have a defective flower meristem; the inner organs are preferentially absent from flowers with defective meristems; in affected flowers, the floral meristem is reduced in size or nearly absent by stage 3 of flower development; other flowers are identical to wild-type. SAM size and the phyllotaxy of flanking primordia appear normal.

Altered leaf polarity; transformation of abaxial cell fates to adaxial cell fates in leaves & floral organs, altered organ shape; heterozygotes have leaves with adaxial epidermal characters (dark green, glossy, trichome-rich surfaces) around their circumference & exhibit varying degrees of radial symmetry & loss of blade outgrowth; some leaves rod like while others are shaped like trumpets (with adaxial tissue on outer surfaces & abaxial tissue on inside of 'bell' of trumpet), leaves grow nearly vertical rather than bending away from the plant; all four types of floral organs affected to some degree.

Description
An ethyl methanesulfonate mutagenesis was performed on clv1-1 mutant seeds to identify enhancers and/or suppressors of the Clv- phenotype. A strong modifier of clv1-1 plants was identified in this screen (pce5). The enhancing mutation was backcrossed to Landsberg erecta (Ler) and isolated. The modifier acted as a single, nuclear trait in all crosses. When combined with strong clv alleles, the enhancer led to the development of corona or ring-like meristems, leading to name the gene CORONA (CNA). The dominant-negative cna-1 allele was formerly known as pce5.
Phenotype
Plants appear superficially wild type in phenotype. Altered meristem size, organogenesis, and stem cell specification. Shoot meristems of 12 day old plants are significantly larger than wild-type meristems); the effect of cna-1 on shoot meristem size in 24 day old plants is reduced compared with earlier developmental time points.
