(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.
Gamic
Definition:
(a.) Pertaining to, or resulting from, sexual connection; formed by the union of the male and female elements.
Example Sentences:
(1) Then pronuclei (gamic nuclei) developed directly into macronuclear anlagen (primordial macronuclei), inducing amicronucleate cells with two anlagen, or, rarely, cells with one anlagen and one micronucleus.
(2) During Tetrahymena conjugation gamic nuclei (pronuclei) are produced, reciprocally exchanged, and fused in each mate.
(3) The ethnographic evidence shows that three of the four subgroups studied belong to the same gamic unity, with the fourth subgroup belonging to another gamic network.
(4) This is why you'll see a lot of what Rawlings calls "gamic" elements on news sites these days.
