A major mechanism of abortive interspecific crosses inAvena appears to be well explained by a hypothesis of polar-nuclei activation (Nishiyama and Yabuno, 1978, 1979). Under the hypothesis, activating value (AV) or response value (RV) of the six following species was estimated, 0.45 being assigned toA. clauda (2x), 0.8 toA. canariensis (2x) andA. prostrata (2x), 0.95 toA. damacena (2x), 1.4 toA. murphyi (4x) and 2.7 toA. byzantina (6x). AV and RV represent the intensity of the mutual reaction… Expand
Endosperm Balance Number and the polar-nuclei activation hypotheses for endosperm development in interspecific crosses of Solanaceae and Gramineae, respectively
TLDR
It is proposed that EBN and PNA be considered as the same concept, based on the stimulative strength of themale nuclei to initiate mitotic divisions in the primary endosperm nucleus and is idependent on a 2∶1 ratio between the RV of the polar nuclei and the AV of the male gamete. Expand
Phylogenetic inferences in Avena based on analysis of FL intron2 sequences
TLDR
Phylogenetic analysis of the FL int2 sequences resulted in topologies that contained four major groups; these groups reemphasize the major genomic divergence between the A and C genomes, and the close relationship among the A, B, and D genomes. Expand
Genome and species relationships in genus Avena based on RAPD and AFLP molecular markers
TLDR
The AB genome tetraploids were found to form a subcluster within the As-genome diploids (AFLPs), indicating their near-autoploid origin and the major genomic divergence between the A and C genomes in Avena. Expand
The evolution pattern of rDNA ITS in Avena and phylogenetic relationship of the Avena species (Poaceae: Aveneae).
TLDR
The major divergence between the A and C genomes is demonstrated whereas the distinction among the A/D genomes was generally not possible and the elimination of C-genome rRNA sequences and the resulting evolutionary inference of hexaploid species are discussed. Expand
Evolutionary insights inferred by molecular analysis of the ITS1-5.8S-ITS2 and IGS Avena sp. sequences.
In an attempt to clarify phylogenetic and genome relationships among 35 diploid (A and C genomes), 13 tetraploid (AB and AC genomes) and 6 hexaploid (ACD genome) Avena taxa, 71 clones of theExpand
Phylogenetic investigation of Avena diploid species and the maternal genome donor of Avena polyploids.
TLDR
The species and genome relationships among 82 Avena accessions representing thirteen diploid species, six tetraploids (AB and AC genomes) and four hexaploid genomes are investigated to infer the evolutionary pathways in Avena using the plastid matK gene and the trnL-F region. Expand

Causal Relationships between the Polar Nuclei in Double Fertilization and Interspecific Cross-incompatibility in Avena
TLDR
In double fertilization of angiosperms the triple fusion of two polar nuclei with a secondary male nucleus is apparently a biological isolation mechanism and may be the most effective barrier to hybridization on occasion. Expand
A mechanism of the alteration of crossability in artificial Avena polyploids
TLDR
It can be said that AV is nearly doubled if the chromosome number is duplicated, or nearly the sum of both parents′ in amphiploids. Expand
Triple fusion of the primary endosperm nucleus as a cause of interspecific cross-incompatibility in Avena
TLDR
The triple fusion of two polar nuclei with a secondary male nucleus is apparently a sexual isolation mechanism, being a barrier to interspecific hybridization in Avena or probably angiosperms. Expand
The significance of genic balance to endosperm development in interspecific crosses
TLDR
This hypothesis brings most intraspecific-interploidy and interspecific crossing data under a single concept with respect to endosperm function, and the implications to isolating mechanisms, 2n gametes, the evolution of disomic polyploids, and reciprocal differences in seed development are discussed. Expand
Somatoplastic Sterility as a Cause of Seed Failure after Interspecific Hybridization.
TLDR
The histological changes leading to failure of fertile ovules of this kind are described and it is shown that essentially the same changes attend seed failure following certain interspecific and intergeneric matings. Expand
Support of the endosperm balance number hypothesis utilizing some tuber-bearingSolanum species
TLDR
The EBN hypothesis is proposed to reconcile the two female genomes: one male genome ratio proposal and the anomalous crossing behavior of some species and its usefulness in predicting the success or failure of a cross and the ploidy of the offspring is demonstrated. Expand
CHROMOSOME RELATIONSHIPS BETWEEN THE CULTIVATED OAT AVENA SATIVA (6x) AND A. VENTRICOSA (2x)
TLDR
The amount of chromosome pairing observed in complex interamphiploid hybrids demonstrates further that A. ventricosa is related to the C. genome of A. sativa and this is readily apparent in the meiotic behaviour of both the F1 hybrid and the amphiploid. Expand
Somatoplastic sterility in reciprocal crosses between 2x- and 4x- plants in Capsicum.
TLDR
Cross pollinations were reciprocally tried between diploid and tetraploid plants of Capsiculee annuum L, the latter having been artificially induced 12 years ago, but the fruits were usually more or less poorly developed. Expand

TLDR
Temperature, rainfall and sunshine are evidently associated with flowering, but temperature, however, seems to exert the most important meteorological influence. Expand
