1. Atypical distyly in Psychotria goyazensis Mull. Arg. (Rubiaceae), an intramorph self-compatible species
Distyly is a genetically controlled floral dimorphism, characterized by the reciprocal positioning of pin and thrum morphs, a heteromorphic incompatibility system and a balanced morph ratio (isoplethy). This study aimed to investigate the phenology, features of distyly, reproductive biology, and floral visitors of Psychotria goyazensis Mull. Arg. (Rubiaceae)

2. VariaÃÃes florais e heterostilia em Palicourea rigida (Rubiaceae) nos cerrados do Brasil Central / Floral variations and heterostyly in Palicourea rigida H.B.K. (Rubiaceae) in the cerrados of Central Brazil
The distyly is a floral polymorphism controlled genetically, where the populations present individuals with pin flowers, that possess long styles and short stamens, and individuals with thrum flowers, that possess short styles and long stamens. Their populations tend to be isoplethyc and anomalies in the distribution of pin and thrum flowers in the populatio

3. Incompatibilidade heteromórfica em Eichhornia Azurea (Pontederiaceae) no Pantanal da Nhecolandia, Mato Grosso do Sul
In heterostylous plants pollination between anthers and stigmas of equivalent heights are often compatible, but any other type of cross or self-pollination result in partial or total incompatibility. Eichhornia azurea is a fluctuant aquatic macrophyte, fixed in the substrate that is generally found in lagoons, rivers and flooded areas in South America. Previ

4. Structural and transcriptional comparative analysis of the S locus regions in two self-incompatible Brassica napus lines.
Self-incompatibility (SI) in Brassica is controlled by a single locus, termed the S locus. There is evidence that two of the S locus genes, SLG, which encodes a secreted glycoprotein, and SRK, which encodes a putative receptor kinase, are required for SI on the stigma side. The current model postulates that a pollen ligand recognizing the SLG/SRK receptors i
