Abstract/Contents: | "The endosperm balance number (EBN) theory states that genomic contribution ratio should be kept at 2:1 maternal/paternal (m:p) ratio for normal endosperm development. However, the endosperm formation in apomictic Paspalum notatum Flu^D"gge′does not depend on the EBN. The aim of this work was to characterize gene expression during seed formation from apomictic and sexual P. notatum using complementary DNA-amplified fragment length polymorphism methodology. To induce the formation of seeds with different m:p genomic ratios, crosses were made between genotypes with different ploidy levels and reproductive modes. RNA was isolated from ovaries 24 h after pollination, when maximum endosperm growth rate was expected. Some of the 49 differentially expressed transcript-derived fragments (DETDFs) provided relevant information. Three of those were found in ovaries of apomictic plants with an EBN different from 2:1. A DETDF was predicted to be involved in sucrose metabolism during the accumulation of hexose and starch in the endosperm and might be related to EBN insensitivity. Twenty-two DETDFs were found in crosses where sexual plants were used as the female parent and the predicted m:p ratio was not 2:1. One of those was related to the failure of fusion of the polar nuclei in Arabidopsis thaliana (L.) Heynh. Finally, three transcripts presented similarity with a casein kinase II that regulates the accumulation of storage products in seeds of A. thaliana. Both processes might be involved in endosperm development in P. notatum." |
