The diploid origin of early calluses in soybean anther culture was recorded by some authors. Since the somatic tissues of mature soybean are known to be highly recalcitrant, it was assumed that, it was unlikely that embryos were derived from anther diploid tissues. However, in the course of our studies, embryo-like structures (ELS) originated from connective calluses were observed. That ELS were similar to those obtained from anthers, indicating the embryogenic ability of connective. The Satt418 microsatellite locus was examined in order to investigate the origin of ELS obtained from soybean anther culture. Four heterozygous plants derived from the cross BRQ96-3065 x BRSMG-Liderança were used as anther donors. A total of 7000 anthers were placed on the induction medium under culture conditions recommended to trigger androgenic response. After 60 days of culture, upper portion of 216 ELS were carefully cut and transferred to a proliferation medium, in order to obtain sufficient tissue for DNA extraction. Callogenic masses originated from 114 ELS were screened for the Satt418 microsatellite locus. ELS originated from plants number 1 and 2 were exclusively heterozygous. In plants 3 and 4, heterozygous and homozygous ELS were identified, suggesting occurrence of somatic embryogenesis and androgenesis in the same system. This unexpected morphogenic response seems to be genotype-dependent and confirm that anther culture is a limited system to trigger androgenesis in soybean, since ELS can be originated from diploid tissue (Supported by CNPq, FAPERGS and CAPES).
