The evolution of female gametophyte development provides an example of how minor ontogenetic modifications can impact the functional biology of seeds. Mature Peperomia-type female gametophytes are normally depicted as 16-nucleate, nine-celled structures. However, recent ultrastructural data have demonstrated that many previous reports were incorrect, suggesting that our understanding of the Peperomia-type ontogeny is incomplete. In this investigation, female gametophyte and early seed…

Female gamete competition in an ancient angiosperm lineage
TLDR
It is posited that prefertilization female gametophyte (egg) competition within individual ovules in addition to male gametic competition and maternal mate choice may have been key features of the earliest angiosperms.
Megasporogenesis and programmed cell death in Tillandsia (Bromeliaceae)
TLDR
The decision on which of the four megaspores will be the supernumerary megaspore in angiosperms, and hence destined to undergo programmed cell death, appears to be linked to the callose layer deposition around the tetrad.
Ovule ontogeny in Billbergia nutans in the evolutionary context of Bromeliaceae (Poales)
TLDR
This study aims to characterise ovule ontogeny in B. nutans and to review the literature concerning ovules at a family level, to verify useful data for taxonomy and identify the evolutionary scenario of embryological characters within the family.
Reproductive biology and success of invasive Australian acacias in Portugal
TLDR
Acacia spp. were shown to be predominantly self-incompatible, but a low level of spontaneous selfing enabled the production of viable offspring, and self-progeny had lower viability than progeny from outcrossing for A.’sdealbata and A.melanoxylon.
Phenological dynamics of the invasive plant Acacia longifolia in Portugal.
TLDR
Among climatic factors, temperature and irradiance were the most significant predictors of the phenological cycle of A. longifolia, but precipitation also exerted a greater influence on budding and flowering of the species.
Genome Features of the Endophytic Actinobacterium Micromonospora lupini Strain Lupac 08: On the Process of Adaptation to an Endophytic Life Style?
TLDR
The genome sequence of Micromonospora lupini Lupac 08 isolated from a nitrogen fixing nodule of the legume Lupinus angustifolius was analysed to identify genomic traits that provide information on this new plant-microbe interaction and suggests that a beneficial effect is produced on the host-plant.
Direction of illumination controls gametophyte orientation in seedless plants and related algae
The environmental influences that determine dorsiventral or axial gametophyte orientation are unknown for most modern seedless plants. To fill this gap, an experimental laboratory system was employed

The developmental basis of an evolutionary diversification of female gametophyte structure in Piper and Piperaceae.
TLDR
Detailed hypotheses indicate that the common ancestor of Piperaceae minus Verhuellia had a Drusa-type female gametophyte, and that evolutionary transitions to derived tetrasporic female gamETophyte ontogenies in Piperaceae are the consequence of key nuclear migration and patterning events at the end of megasporogenesis.
Female gametophyte development in Aristolochia labiata Willd. (Aristolochiaceae)
TLDR
Detailed analyses of female gametophyte development in Aristolochia labiata that combine light and confocal microscopy with three-dimensional computer reconstruction demonstrate that, at the two-nucleate stage of development, separation of nuclei to opposite poles of the female gamete does not appear to be dependent on vacuolar expansion as generally hypothesized.
Embryology of Manekia naranjoana (Piperaceae) and the origin of tetrasporic, 16-nucleate female gametophytes in Piperales.
TLDR
The data suggest the common ancestor of Piperaceae was tetrasporic and retained a plesiomorphic bipolar body plan, producing a "functionally bisporic" form of triploid endosperm derived from the lineal descendants of two megaspores and a sperm.
An embryological study of Kava, Piper methysticum
TLDR
It is suggested that, although the lack of fruit formation in this species is not because of any deficiencies in its embryological development, it may be due to a simple self-incompatibility mechanism.
New perspectives on the angiosperm female gametophyte
  • D. Haig
  • Biology
    The Botanical Review
  • 2008
TLDR
A new classification of developmental algorithms is presented that emphasizes the fate of the germinal spore and its derivatives, and builds upon previous classifications of angiosperm female gametophytes.
The four-celled female gametophyte of Illicium (Illiciaceae; Austrobaileyales): implications for understanding the origin and early evolution of monocots, eumagnoliids,and eudicots.
TLDR
A character analysis based on more than 250 embryological studies indicates that a transition from an ancestrally four-celled/four-nucleate Illicium-like female gametophyte to a seven-CElled/eight-n nucleate female gamETophyte occurred in the common ancestor of the sister group to Austrobaileyales.
Embryology of Zippelia begoniaefolia (Piperaceae) and its systematic relationships
TLDR
By comparison with the other piperaceous taxa using embryological and botanical features, Zippelia is referred to as a basal taxon and a more isolated evolutionary line or a blind branch in the Piperaceae.
Recent Investigations Upon the Embryo Sac of Angiosperms
Peperomia, in regard to the embryo sac, probably represents the most primitive form yet described among the angiosperms. The absence of a definite egg apparatus and antipodals, and especially the
Megasporogenesis and programmed cell death in Tillandsia (Bromeliaceae)
TLDR
The decision on which of the four megaspores will be the supernumerary megaspore in angiosperms, and hence destined to undergo programmed cell death, appears to be linked to the callose layer deposition around the tetrad.
