“…On the placental surface of the peach, alterations in pollen tube growth were first seen associated with the obturator (Arbeloa & Herrero 1987), which strongly suggested that a secretion by this structure was required for the pollen tube to progress. Further, in plants where a delayed penetration of the ovule was recorded (Herrero & Arbeloa 1989), it was later discovered that the delay coincided precisely with the time required for the ovules to produce a secretion at the exostome and micropyle (Herrero 2000).…”

“…The timing of these events is crucial for, far from been a passive structure, the pistil continues to develop along a pathway that can both favour and discourage growth of the pollen tube. This is particularly apparent in the ovary, which owing to the basipetal maturation of the pistil (Herrero & Arbeloa 1989), develops last. Of course, the pollen tube itself is following its own developmental pathway as it passes through the stigma and into the ovary, and the synchrony of these parallel pathways is clearly a key to successful fertilization and seed formation.…”

Successful mating clearly requires synchronous development of the male and female sexual organs. Evidence is accumulating that this synchrony of development also persists after pollination, with both pollen and pistil following complex, but highly integrated developmental pathways. The timing of the malefemale interaction is crucial for the pistil, which, far from being a mature passive structure, is engaged in a continuing programme of development: only being receptive to the advances of the pollen for a relatively short window of time. This developmental programme is most conspicuous in the ovary, and this review focuses on the interaction between the male and female tissues in this structure. The review first considers pollen tube development in the ovary, concentrating of the mechanisms by which its growth is modulated at various control points associated with structures within the ovary. Second, alterations to this 'normal' developmental programme are reviewed and considered in the context of a breakdown of developmental synchrony. Finally, the consequences of male-female developmental synchrony and asynchrony are explored. Clearly, a synchronous male-female relationship leads to a successful fertilization. However, lack of synchrony also occurs, and could emerge as a powerful tool to investigate the regulation of mating.

“…The pollen-style and pollen-pollen interactions are known to play an important role in the reproductive success of single male gametophytes (Sari-Gorla et al, 1976;Ottaviano & Sari-Gorla, 1979; Sari- Gorla & Rovida, 1980;Herrero & Arbeloa, 1989), and are expected to operate in natural populations.…”

“…The most comprehensive analysis of the genetic control of pollen fitness components was carried out in maize (Ottaviano et a!., 1988): grain germinability and tube growth revealed a large amount of variability and high heritability; a signi-ficant response to gametophytic selection for tube growth rate and a correlated response for sporophytic traits were detected, proving genetic overlap in the control of the pollen tube growth and the vigour of sporophytic tissues. Moreover, the fertilization ability of a given pollen genotype is modulated by intergametophytic effects (Sari-Gorla & Rovida, 1980), by environmental effects (Young, 1992) and by interactions with the stylar tissue (Pfahler, 1967;HeslopHarrison, 1975;Sari-Gorla et a!., 1976;Herrero & Arbeloa, 1989).…”

Pollen competition and variability in pollen fitness can produce non-random fertilization with respect to pollen genotypes, and, owing to the large extent of genetic overlap between the gametophytic and sporophytic phases of the life-cycle, can affect the latter. Differences in pollen fitness are due to many factors, of which pollen grain germinability and pollen tube growth rate are the main components. The identification and chromosomal localization of the genes that mainly affect pollen fitness variability were carried out by RFLP analysis, applied to a recombinant inbred population that had been characterized for about 200 restriction loci. Germination ability and pollen tube growth rate were evaluated by means of the pollen mixture technique. Both traits revealed a large variability and high heritability (0.71 0.05 for tube growth rate and 0.77 0.04 for grain germinability). Analysis of the association between the expression of the characters and the allelic composition at each of the restriction loci revealed a significant regression on 29 loci in the case of pollen tube growth rate and on 26 in the case of pollen grain germinability. However, considering only uncorrelated loci, in order to avoid false assignments, the minimum number of quantitative trait loci (QTL)s with major effects was five for the tube growth rate and six for grain germinability. The amount of genetic variability of the characters explained by the molecular markers was 0.89 (tube growth rate) and 0.79 (grain germinability), signifying that almost all the genetic variability for these traits is due to QTL located in the chromosomal regions indicated by the analysis. Most of the QTL identified relate to either one trait or the other, which suggests that they are genetically controlled by specific sets of genes.

“…In peach, pollen tube growth has been related to changes in the pistil structures which the pollen tube has to pass through on its way from the stigma to the ovule: starch, present all along the stylar tract at anthesis, vanishes as the pollen tubes pass by, indicating that the pollen tube growth is heterotrophic (Herrero & Arbeloa, 1989).…”

Detection of genetic factors controlling pollen–style interaction in maize

et al. 1995

In order to detect loci specifically related to pollen-style interaction in maize, linkage analysis to RFLP markers was performed on a population of recombinant inbred lines, the pollen of which was used to pollinate female plants of two different genotypes: the F1 from which the recombinant inbred population was derived ('self female') and a genetically unrelated hybrid genotype ('cross female'). Besides pollen grain germinability and pollen tube growth rate on the two females, pollen general competitive ability and pollen specific competitive ability for both traits were evaluated, following the procedure used to estimate general and specific combining ability, applied to the pollen-style genetic combination instead of to the hybrid genetic combination. A clear advantage of recombinant inbred line pollen, in terms of germination and early growth, was revealed on self female tissues whereas an inverse effect was detected for tube growth rate: tube growth, until fertilization, was faster on the female of unrelated genotype. Linkage analysis to molecular markers (RFLP) of germinability and of tube growth rate on the two stylar genotypes identified nine QTLs for the first trait on the self and eight on the cross female; four chromosome regions for tube growth rate were detected on the self and 11 on the cross style. Most of the general competitive ability effects were localized in the regions where QTLs for germinability or pollen tube growth were detected, in particular on the cross female; on the contrary, most of the loci for pollen specific competitive ability effects proved to be localized in different chromosome regions.
