The wild relatives of rice are a valuable source of desirable agronomic traits, but prefertilization barriers operate in crosses of Oryza sativa L. with the wild Oryza species and related genera. Pollen germination was normal in crosses with O. brachyantha, O. eichingeri, O. officinalis, and O. ridleyi and slightly inhibited in crosses with Rhynchoryza subulata. Stigmal penetration of O. brachyantha and R. subulata pollen tubes was inhibited, while O. ridleyi pollen tubes showed both incompatible and weakly compatible reactions. Pollen tubes of O. eichingeri, O. officinalis, and O. ridleyi penetrated the stigma, but growth was frequently inhibited in the style or ovary wall, particularly in O. eichingeri crosses. The effect of postpollination application of boric acid, the immunosuppressant ε-aminocaproic acid (EACA), and gibberellic acid (GA3) and of ambient temperature (29 and 35 °C) on germination and pollen tube growth was investigated. Boric acid, EACA, and GA3 inhibited germination of O. brachyantha pollen, and boric acid and EACA inhibited pollen tube growth of O. brachyantha, O. eichingeri, O. ridleyi (35 °C), and R. subulata (29 °C). Pollen tube growth in the control and GA3 treatments was similar. Temperature had no effect on pollen germination and pollen tube growth was stimulated in O. ridleyi crosses at 35 °C only. The nature of incompatibility operating in these crosses is discussed.Key words: incompatibility, pollen tube growth, fertilization, Oryza, interspecific cross, intergeneric cross.

Abstract Mutant analysis represents one of the most reliable approaches to identifying genes involved in plant development. The screening of the Versailles collection of Arabidopsis thaliana T-DNA insertion transformants has allowed us to isolate different mutations affecting male gametophytic functions and viability. Among several mutated lines, five have been extensively studied at the genetic, molecular, and cytological levels. For each mutant, several generations of selfing and outcrossing have been carried out, leading to the conclusion that all these mutations are tagged and affect only the male gametophyte. However, only one out of the five mutations is completely penetrant. A variable number of T-DNA copies has integrated in the mutant lines, although all segregate at one mutated locus. Two mutants could be defined as “early mutants”: the mutated genes are presumably expressed during pollen grain maturation and their alteration leads to the production of nonfunctional pollen grains. Two other mutants could be defined as “late mutant” since their pollen is able to germinate but pollen tube growth is highly disturbed. Screening for segregation ratio distortions followed by thorough genetic analysis proved to be a powerful tool for identifying gametophytic mutations of all phases of pollen development.
