Oppositional Alleles Causing Cross-Incompatibility in Trifolium Repens.
N SEVERAL species in which cross-incompatibility is determined by I multiple oppositional alleles, different types of tests have shown that these series of alleles are very extensive. The test yielding the most decisive results and involving the fewest crosses consists of making all possible reciprocal combinations (that is, diallel crosses) between plants which have one S factor in common. Thi...
متن کاملNatural antisense transcripts of Trifolium repens dehydrins
Dehydrins (group 2 LEA proteins) tend to accumulate late in embryogenesis and in response to stress leading to cell dehydration (e.g., drought, low temperature, and salinity). The expression pattern of group 2 LEA genes is frequently associated with higher tolerance of crop plants to abiotic stresses such as cold and drought. All dehydrins have at least one conserved, lysine-rich 15-amino acid ...
متن کاملNatural antisense transcripts of Trifolium repens dehydrins
The recently described complex nature of some dehydrin-coding sequences in Trifolium repens could explain the considerable variability among transcripts originating from a single gene.1 For some of the sequences the existence of natural antisense transcripts (NAT s), which could form sense-antisense (SAS) pairs, was predicted. The present study demonstrates that cis-natural antisense transcript...
متن کاملMutations of Self-Incompatibility Alleles in Trifolium Pratense and T. Repens.
HE existence of several allelomorphs at the S locus has been demonstrated in T Nicotiana spp. (EAST and YARNELL 1929), Veronica syriaca (LEHMANN 1926), Antirrhinum glutinosum ( GRUBER 1932), Trifolium pfatense (WILLIAMS 1939; and WILLIAMS and WILLIAMS 1947), Oenothera organensis (EMERSON 1939, 1940) and Trifolium repens (ATWOOD 1944). In Trifolium pratense, BATEMAN (1947) calculated that the nu...
متن کاملCyanotypic frequencies in adjacent and mixed populations of Trifolium occidentale Coombe and Trifolium repens L. are regulated by different mechanisms.
The cyanogenic polymorphism in Trifolium repens is caused by the variation in two genes, the interaction of which produces four distinct cyanotypes. Along the Atlantic coasts of Bretagne, T. repens is sometimes found in populations mixed with the related species Trifolium occidentale, although the latter species usually occurs only in a narrow fringe along the coast, whereas T. repens is a more...
