RFLP mapping in maize is described. Neither the order of the translocation breakpoints nor the order of the RFLP loci need be known, since presence/absence information will determine unambiguously the order of both. Correlations with the physical map are possible and a definitively ordered RFLP map can be developed - a map whose order is not based on the observation of recombinational events. Because of the numerous translocations which exist in maize, it is anticipated that the physical resolution currently exceeds the density of the RFLP map. Thus, the majority of the RFLP loci should be ordered using this technique. Currently, all 879 translocation stocks are being crossed to a standard r-x1 containing line and the appropriate tester stocks derived to provide the progeny for future screening for double hemizygotes. |

We used an expert system for soil classification to curate soil data and improve its quality.
The system is the first to accurately classify soil profiles to the fourth level of the current
version of the Brazilian Soil Classification System (SiBCS). We analyzed 94 soil profiles
using the expert system, which guided the necessary changes on soil data to make it
consistent with the corresponding classifications. About 45% of soil profiles did not require
data treatment, and most changes were related to horizon symbols. Even after data
treatment, changes in classification were necessary for almost 40% of the profiles on at least
one categorical level. Therefore, using an expert system for soil classification can help
identify inconsistencies in data and classifications of soil profiles, in addition to guiding the
necessary changes. It can also help improve the SiBCS. |
