Pollen Tube Growth Rates in Zea mays: Implications for Genetic Improvement of Crops.

Science (New York, N.Y.)

Ottaviano E, Sari-Gorla M, Mulcahy DL.
PMID: 17837425
Science. 1980 Oct 24;210(4468):437-8. doi: 10.1126/science.210.4468.437.

Speed of pollen tube growth is positively correlated with the quality of the resultant sporophytic generation. Therefore, gametophytic competition may be an important adaptive mechanism. Furthermore, pollen tube growth rates may be used to predict the quality of F(1)...

Pollen competitive ability in maize: within population variability and response to selection.

TAG. Theoretical and applied genetics. Theoretische und angewandte Genetik

Ottaviano E, Sari-Gorla M, Villa M.
PMID: 24232283
Theor Appl Genet. 1988 Oct;76(4):601-8. doi: 10.1007/BF00260915.

Male gametophytic selection can play a special role in the evolution of higher plant populations. The main assumption - gametophytic-sporophytic gene expression of a large portion of a plant's genes - has been proven by a number of studies....

Pollen-pistil interaction in maize: effects on genetic variation of pollen traits.

TAG. Theoretical and applied genetics. Theoretische und angewandte Genetik

Sari-Gorla M, Mulcahy DL, Villa M, Rigola D.
PMID: 24169980
Theor Appl Genet. 1995 Nov;91(6):936-40. doi: 10.1007/BF00223903.

Various factors (pollen diameter, in vitro germination and tube length, in vivo growth rate in selfed and nonselfed styles) which could possibly contribute to the competitive ability of pollen were investigated on 30 Zea mays L. inbred lines. The...

Sporophytic response to pollen selection for Alachlor tolerance in maize.

TAG. Theoretical and applied genetics. Theoretische und angewandte Genetik

Sari-Gorla M, Ferrario S, Frascaroli E, Frova C, Landi P, Villa M.
PMID: 24186182
Theor Appl Genet. 1994 Aug;88(6):812-7. doi: 10.1007/BF01253990.

In order to assess the efficiency of male gametophytic selection (MGS) for crop improvement, pollen selection for tolerance to herbicide was applied in maize. The experiment was designed to test the parallel reactivity to Alachlor of pollen and plants...

Molecular markers (RFLPs and HSPs) for the genetic dissection of thermotolerance in maize.

TAG. Theoretical and applied genetics. Theoretische und angewandte Genetik

Ottaviano E, Sari Gorla M, Pè E, Frova C.
PMID: 24221430
Theor Appl Genet. 1991 Jun;81(6):713-9. doi: 10.1007/BF00224979.

Cellular membrane stability (CMS) is a physiological index widely used to evaluate thermostability in plants. The genetic basis of the character has been studied following two different approaches: restriction fragment length polymorphism (RFLP) analysis, and the effects of segregating...

Male gametophytic selection in maize.

TAG. Theoretical and applied genetics. Theoretische und angewandte Genetik

Ottaviano E, Sari Gorla M, Pe E.
PMID: 24270824
Theor Appl Genet. 1982 Sep;63(3):249-54. doi: 10.1007/BF00304004.

There is evidence that male gametophyte selection is a widespread phenomenon in higher plants. The pollen tube growth rate is one of the main components of gametophyte selective value; genetic variability for this trait, due to the effect of...

Genetic variability of gametophyte growth rate in maize.

TAG. Theoretical and applied genetics. Theoretische und angewandte Genetik

Sari Gorla M, Ottaviano E, Faini D.
PMID: 24420123
Theor Appl Genet. 1975 Jan;46(6):289-94. doi: 10.1007/BF00281151.

In order to measure differences in the pollen growth rate of numerous lines of maize and to investigate the main features of their genetic control, gametophyte growth was studied in vitro and in vivo. In vitro pollen tube growth...

The extent of gametophytic-sporophytic gene expression in maize.

TAG. Theoretical and applied genetics. Theoretische und angewandte Genetik

Sari Gorla M, Frova C, Binelli G, Ottaviano E.
PMID: 24247769
Theor Appl Genet. 1986 Apr;72(1):42-7. doi: 10.1007/BF00261452.

To determine the extent of gametophytic gene expression and the type of transcription, haploid or haplo-diploid, of the genes, isozymes were used as genetic markers. Fifteen enzymatic systems, including thirty-four isozymes, were studied. The determination of the type of...
