SummaryUsing five diploid, two tetraploid and three hexaploid Avena species (x=7) 78 reciprocal crosses were made. Of these 74 were successfull, though the frequency of seed set varied greatly. The development of hybrid seeds differed widely between cross combinations, especially in reciprocal crosses. Hybrid seeds were grouped into four types, (1) normal kernels, well developed and germinative (designated as D+); (2) shrivelled-empty kernels, which do not germinate (E−); (3) small viable… 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
A gene block causing cross-incompatibility hidden in wild and cultivated rice.
TLDR
The results revealed that the death of young F(1) zygotes was controlled by the parental genotypes rather than by the genotype of the hybrid zygote itself since all three genes acted sporophytically, which strongly suggests an involvement of parent-of-origin effects. Expand
Two loosely linked genes controlling the female specificity for cross-incompatibility in rice
TLDR
The present results showed that CIF is controlled not only by Cif but also by an additional gene(s) loosely linked with it, which proposes here that Cif1 (formerly named as Cif) and Cif2 determine CIF. Expand

TLDR
The pattern of relationship between the crossability, including plumpness, germination and others of hybrid seeds, and the AI% was found to completely agree with that expected from the standard cross-compatibility system in Avena. Expand
The reproductive biology of the potato and its implication for breeding
TLDR
The use and manipulation of 2n gametes, stylar barriers and EBN have been used effectively in germplasm transfer from species to cultivated potato. Expand
Abortion and determination of stages for embryo rescue in crosses between sweet-potato, Ipomoea batatas Lam. (2n=6x=90) and its wild relative, I. trifida (H. B. K.) G. Don. (2n=2x=30)
TLDR
The results suggested that the appropriate time for embryo rescue in interspecific crosses is at the globular stage, and it would be possible to increase the number of surviving embryos up to 30 times in inter specific crosses and 0.02 times in intraspecific crosses with respect to natural conditions without embryo rescue.

Kin conflict in seed development: an interdependent but fractious collective.
  • D. Haig
  • Biology, Medicine
  • Annual review of cell and developmental biology
  • 2013
TLDR
Maternally expressed small-interfering RNAs (siRNAs) are predicted to associate with growth-enhancing genes and seed size is determined by an interplay between growth of maternal integuments, which limits seed size, and of filial endosperm, which promotes larger seeds. Expand
Seed evolution: parental conflicts in a multi-generational household
  • N. Pires
  • Biology, Medicine
  • Biomolecular concepts
  • 2014
TLDR
The evolutionary steps that resulted in the appearance of seeds and endosperm, and the epigenetic and genetic mechanisms that allow a harmonious coinhabitance of multiple generations within a single seed are discussed. Expand
The Mechanism of Polyembryonic Seed Set in Paspalum notatum
TLDR
It can be concluded that the first sac has temporal dominant in embryo sac formation, and has the positional dominant in fertilization and subsequent development of embryo sac when compared with the other sacs in polyembryonic ovules. Expand

Abnormalities of endosperm development inLilium hybrids
TLDR
Of 191 interspecific crosses attempted between 27 different species representing different subgenera of Lilium only 14 gave rise to seeds and only 6 of these were viable, suggesting that sterility results from genetic imbalance of the endosperm itself rather than interaction of theendosperm with either embryo or maternal tissue.

STUDIES IN BRITISH PRIMULAS
TLDR
Crosses between three diploid species Primula veris, P. vulgaris and P. elatior show marked seed incompatibility and the hypothesis that the degree of seed failure can be related to the difference in the genetic values of the paternal and maternal contributions to the tissues of the seed is tested. 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
Double Fertilization and Development of the Seed in Angiosperms
TLDR
The evidence on differential survival of seeds following self- and cross-fertilization, growth of endosperm and embryo, histological changes associated with collapse, and comparative lack of ovule food reserves are considered in relation to the role of double fertilization in seed formation. Expand

TLDR
It is desirable to find more data are desirable on the question whether seed failure following hybridization of distantly related forms follows a common basic pattern or differs significantly from group to group. 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

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