}SummaryMany aberrant somatic sectors on the corollas of heterozygous Antirrhinum majus can be related to a number of genetic causes while twin-spots are attributed to somatic crossing-over, hitherto, considered a relatively rare occurrence in higher plants. The administration of caffeine increases the frequency of single aberrant sites and also of twin-spots. The inclusion of the unstable genes nivea-recurrens and pallida-recurrens has no effect on the frequency of twin-spots. Homozygosity…

HOMOEOLOGOUS CHROMOSOME PAIRING AND RESTRICTED SEGREGATION IN THE FERN CERATOPTERIS
- Biology
- 1978
An inbreeding study of the polyploid fern Ceratopteris shows segregation of a marker characterized by pale green gametophytes, and a model based upon a duplicated locus and homoeologous chromosome pairing can explain the segregational behavior.
Somatic Mosaicism inPlants with Special Reference toSomatic Crossing
- Biology

Theability of plant systems inanalyzing a host ofgenetic endpoints, including chromosome aberrations lkedeletions, somatic crossing over, numerical inequality, geneconversion, paramutations and point mutations is shown.
Characterization of X-ray induced increase of mitotic cross-overs in Glycine max
- Biology, MedicineTheoretical and Applied Genetics

It is ascertained that Mitomycin C is more specific for Db spot induction than X-rays, and the frequency of light green spots on normal dark green, Y/Y, seedlings was tabulated and, as with all other spot types, increased with increasing X-ray dosage.
Somatic hybridization between Lycopersicon esculentum and Solanum tuberosum
- Biology

This thesis describes an analysis of the possibilities and limitations of asymmetric somatic hybridization between tomato and potato and shows that two nitrate reductase-deficient tomato mutants could be used as selectable markers in somatic Hybridization experiments with potato.
Somatic mosaicism in plants with special reference to somatic crossing over
- Biology, MedicineEnvironmental health perspectives

A case is presented here which shows the ability of plant systems in analyzing a host of genetic end points, including chromosome aberrations like deletions, somatic crossing over, numerical inequality, gene conversion, paramutations and point mutations, in analyzing mutagenicity.
Effect of colchicine on somatic crossing over induced by mitomycin C in soybean (Glycine max)
- BiologyGenetica

The results suggest that there is a colchicine specific effect which results in reduction in somatic crossing over in interphase nuclei.
Evidence for gene transfer by the use of sublethally irradiated pollen in Zea mays and theory of occurrence by chromosome repair through somatic recombination and gene conversion
- BiologyMolecular and General Genetics MGG
- 2004
It is suggested that in divisions during early embryogeny following normal fertilisation by pollen treated with near-lethal doses of radiation, there is selection of cells in which irradiation damaged segment of paternal chromosomes are repaired, through homologous somatic recombination and gene conversion, by segments from the normal maternal chromosomes.
Evolution of Reproductive Systems in the Gramineae
- Biology
- 1981
The review of Evans (1964) elegantly reveals data on the interplay of daylength, temperature, and vernalization on inflorescence development, and a survey of the breeding systems known in the Gramineae is presented.

Instability at the Pal locus in Antirrhinum majus
- BiologyHeredity
- 1964
There has always been uncertainty as to whether genetic changes which are sufficiently frequent to give obvious somatic variegation can be regarded as in the same category as gene mutations happening at more ordinary frequencies, but recent developments tend to strengthen the belief that such differences do exist.
INDUCED PREMEIOTIC EXCHANGE OF LINKED MARKERS IN THE ANGIOSPERM ARABIDOPSIS.
- BiologyGenetics

This report demonstrates induced premeiotic exchange of linked markers in an angiosperm, simulating crossing over, and indicates a different mechanism, possibly a translocation between homologous chromatids.
Evocation of instability at the pal locus in Antirrhinum majus
- BiologyHeredity
- 1976
A new type of genetic instability in two Antirrhinum plants is investigated, associated with a special allele of Pal, an anthocyanin-producing gene, which is denoted as palrec-low to distinguish it from the hitherto characterised “standard” palrec, which has a much higher mutation frequency.
A comparison of the instabilities at the Nivea and Pallida loci in Antirrhinum majus

Somatic paramutation in homozygous nivrec regularly occurs and varies with plant development, and depends on the direction of the cross; paramutagenic female parents induce a higher frequency of paramutants.

Observations indicate that it is not the mere inhibition of DNA synthesis, but some rather more specific event in DNA repair which is responsible for complementary exchanges in somatic crossing over.
