Acesso restrito. p. 699-711The mating system of seven sympatric taxa of Chamaecrista occurring in the Chapada Diamantina Mountains, northeastern Brazil, was studied to determine the occurrence of self-incompatibility and interspecific genetic isolation mechanisms within the group. Self- and cross-pollination experiments and inter-taxon bidirectional crosses were performed. All of the populations were selfcompatible and showed high percentages of spontaneous seed abortion on both self- and cross-pollinated fruits. The inter-incompatibility among the taxa of Chamaecrista is directed by different mechanisms depending on their degrees of phylogenetic proximity. In the crosses between closely related taxa (same clade), seed inviability was observed in the crossing pairs C. desvauxii var. graminea 9 C. desvauxii var. latistipula, and C. chapadae 9 C. glaucofilix. Inter-compatibility between species of the same clade occurred in C. blanchetii and C. confertiformis, with the formation of viable seeds. Pre-zygotic gametophytic reproductive isolation was observed among taxa of different clades, without penetration of the pollen tube into the ovule, or post-zygotic isolation through embryo or endosperm inviability, with abortion of the seeds. Interincompatibility represents an important factor in reproductive isolation and thus in the maintenance of the genetic identity of sympatric taxa that flower in synchrony and share pollinators.Submitted by Santiago Fabio (fabio.ssantiago@hotmail.com) on 2013-06-25T16:37:32Z No. of bitstreams: 1 33333333333.pdf: 472016 bytes, checksum: c9c815cc8ec5a1f86d09669c000ef5b3 (MD5)Approved for entry into archive by Rodrigo Meirelles (rodrigomei@ufba.br) on 2013-11-16T13:07:09Z (GMT) No. of bitstreams: 1 33333333333.pdf: 472016 bytes, checksum: c9c815cc8ec5a1f86d09669c000ef5b3 (MD5)Made available in DSpace on 2013-11-16T13:07:09Z (GMT).
