In connection with the vast accumulation of facts concerning reproduction, our morphological categories are in danger of becoming too rigid. Emphasis is laid upon secondary features, and the fundamental features common to all reproduction escape attention.

In recent years there has been a growing awareness of the importance of reproductive biology to crop production and there has been a tremendous increase in research on reproductive structures of higher plants. Presented here is a wide information of different aspects of micro- and macrosporogenesis, pollen-stigma interaction and recognition, pollen ...

Plant Reproductive Development during Spaceflight
2003Reproductive development in microgravity has now been studied in a variety of plants; Arabidopsis, Brassica, and Triticum have been especially well studied. Earlier indications that gravity might be required for some stage of reproductive development have now been refuted.

Abstract This collection of reviews by leading investigators examines plant reproduction within a framework of evolutionary ecology. The contributors discuss conceptual issues, showing the importance of sex allocation, sexual selection and inclusive fitness, and the dimensions of paternity and maternity in plants.

In the period since the first B symposium in 1997 (Bell and Rerkasem 1997; Dell et al., 1997), progress in defining either structural or metabolic roles for B in reproductive parts of seed plants has been disappointing. However, better control of B in solution (Huang et al., 1999) has allowed B effects on anther and pollen development in wheat to be ...
