What's the difference between agamic and parthenogenetic?
Agamic
Definition:
(a.) Produced without sexual union; as, agamic or unfertilized eggs.
(a.) Not having visible organs of reproduction, as flowerless plants; agamous.
Example Sentences:
(1) In agamous-1, stamens to petals; in apetala2-1, sepals to leaves and petals to staminoid petals; in apetala3-1, petals to sepals and stamens to carpels; in pistillata-1, petals to sepals.
(2) The spatial pattern of AGAMOUS expression remains unaltered in superman flowers as compared to wild-type flowers.
(3) To test this, the expression patterns of AGAMOUS and APETALA3 were examined in superman flowers.
(4) The paper is concerned with the first experience of intracavitary gamma-therapy of uterine cancer using the AGAM unit ensuring simultaneous delivery of Cs-137 sources along 3 channels.
(5) Essentially additive phenotypes are observed in superman agamous and superman apetala2 double mutants.
(6) Mutations in the homeotic gene agamous of the plant Arabidopsis cause the transformation of the floral sex organs.
(7) Mutations in the AGAMOUS (AG) gene cause transformations in two adjacent whorls of the Arabidopsis flower.
(8) These phenotypes are consistent with predictions from the genetic model, show that expression of AGAMOUS is sufficient to provide ectopic C function, and demonstrate that the structure of flowers can be manipulated in a predictable manner by altering the expression of a single regulatory gene.
(9) The agamous gene therefore probably encodes a transcription factor that regulates genes determining stamen and carpel development in wild-type flowers.
(10) The predicted products of floral homeotic genes, AGAMOUS (AG) from Arabidopsis thaliana and DEFICIENS A (DEF A) from Antirrhinum majus, have been shown previously to share strong sequence similarity with transcription factors from humans (SRF) and yeast (MCM1).
(11) We propose that the AP1 and AP2 gene products act in concert with the product of the agamous (AG) locus to establish a determinate floral meristem, whereas other homeotic gene products are required for cells to differentiate correctly according to their position.
(12) Similar regions are found in other proteins, such as ARG80, Deficiens and Agamous.
(13) ARG80 and Agamous exhibit similar DNA binding specificities but do not interact with either STE12 or p62TCF.
(14) Five genes with homology to the floral homeotic genes deficiens of Antirrhinum and agamous of Arabidopsis were isolated from tomato.
(15) To test the genetic model, we have generated transgenic tobacco plants that ectopically express the AGAMOUS gene from Brassica napus, which is necessary for the C function.
(16) The second maturation division starts immediately after the completion of the first division and is morphologically similar to agamic mitosis of the micronuclei of D. nasutum.
(17) We characterized the distribution of AGAMOUS (AG) RNA during early flower development in Arabidopsis.
(18) LEAFY expression procedes expression of the homeotic genes AGAMOUS and APETALA3, which specify organ identify within the flower.
(19) Cloning and sequence analysis of agamous suggest that it encodes a protein with a high degree of sequence similarity to the DNA-binding region of transcription factors from yeast and humans and to the product of a homeotic gene from Antirrhinum.
(20) Further, the phenotypes of multiple mutant lines indicate that the wild-type products of the AGAMOUS and APETALA2 genes interact antagonistically.
Parthenogenetic
Definition:
(a.) Of, pertaining to, or produced by, parthenogenesis; as, parthenogenetic forms.
Example Sentences:
(1) Interspecific hybridization between sexual species carrying different b-alleles and producing different B subunits may be responsible for the heterozygosity at the lactate dehydrogenase b-locus in diploid parthenogenetic Cnemidophours.
(2) The parthenogenetic controls were negative (1.4% and 0%).
(3) These findings demonstrate a new and simple method of inducing post-implantation parthenogenetic development in the mouse, and stress the necessity of taking into account the possible consequences of anaesthesia in the early post-ovulatory period.
(4) The postimplantation viability of parthenogenetic eggs was tested and the results showed that parthenogenetic rabbit embryos died at a similar stage of development to the parathenogenetic mouse embryos.
(5) The accumulating process and concentration ratios of ingested blood meals in the larvae and nymphs of Amblyomma testudinarium, Haemaphysalis campanulata, H. concinna, H. formosensis, H. hystricis, H. kitaokai, the bisexual and parthenogenetic strains of H. longicornis, H. megaspinosa, and Ixodes persulcatus on rabbits and Argas japonicus on chickens were comparatively investigated.
(6) However, the contribution of parthenogenetic cells to the brain does appear to be influenced by strain background, since a marked improvement in the survival of CFLP, 129 and perhaps SWR parthenogenetic cells in chimeric brains was observed compared with F2 cells.
(7) Prolonged in vitro culture of oocytes after parthenogenetic activation and diploidization treatment showed that formed pronuclei were able to fuse and single prometaphase to telophase mitotic cleavage figures developed in all oocytes fixed 28 h after activation, except one cytochalasin B-treated oocyte with two prometaphase sets of chromosomes.
(8) The presence of duplications in all of these parthenogens, but not among representatives of their maternal sexual ancestors, suggests that the duplications arose in the parthenogenetic form.
(9) Freshly ovulated rabbit oocytes were activated parthenogenetically by periodically repeated calcium stimuli generated by electric field pulses applied onto the plasma membrane.
(10) Two morphologically different generations of nematodes, gamagenetic and parthenogenetic ones, develop in the body cavity of the insects.
(11) Parthenogenetic embryos display a fairly normal development until implantation.
(12) We determined the morphological survival rate, the pattern of parthenogenetic activation, and the microtubular and chromosomal organization.
(13) A high frequency of parthenogenetic activation occurs when ovulated mouse oocytes are briefly exposed to a dilute solution of ethanol in vitro.
(14) By 6.5 days, however, in almost every embryo, parthenogenetically derived cells were not detected in the extraembryonic trophoblast tissue descended from the TE.
(15) Southern blot analysis of all populations shows that they can be grouped into three classes: a) American bisexuals; b) Eurasian bisexuals, and c) parthenogenetic organisms (all from Eurasia).
(16) Despite these losses there has been a large increase in fecundity in the parthenogenetic strain.
(17) Past experiments on teratocarcinoma induction by ectopic grafting of early rodent embryos or fetal germinal ridges have remained ambiguous because embryos ordinarily soon form germ cells, and parthenogenetic germ cells form "embryos."
(18) Oocytes exhibited isolated maturative changes almost exclusively in FSH-LH cultures, such as cortical granule synthesis, resumption of meiosis, polar body extrusion, and two-cell parthenogenetic cleavage.
(19) The parthenogenetic Haemaphysalis longicornis larvae engorged on cattle naturally infected with Theileria sergenti were reared at 24 degrees C. The resultant nymphal ticks were incubated at 37 degrees C to clear the effect of incubation on the development and maturation of sporozoites.
(20) Blebbing exists only in oocytes activated by sperm in vivo or in vitro, or parthenogenetically by treatment with ethanol or puromycin.
