Rapid progress in genomic research and the development of genome-wide molecular markers for various crops significantly improved our knowledge on plant domestication and evolution. Molecular markers and other genomic tools have been used to understand the evolutionary changes that converted wild plants into domesticated crops, and the identification of loci behind domestication syndrome traits will have significant importance in the fast-track domestication of new plants. The application of genomics-assisted selection in plant breeding programs has significantly contributed to efficient plant breeding for desirable traits. Genomic tools also facilitated the efficient identification of progenitors of crops as well as centers of domestication. Multiple genomic regions with signature of selection during plant domestication have been found in various crops. Extensive analyses of plant genomes revealed that genes underlying domestication syndrome traits show a significant loss of diversity, for example, up to 95% of genetic diversity in wild relatives has been lost during domestication process in extreme cases. Genomic research revealed repeated occurrence of polyploidization during plant evolution and various interesting events that occurred following polyploidization such as gene loss and silencing. The loss of most replicated genes through time and nonrandom retention of some duplicated genes that serve as signatures of polyploidy are among interesting changes in polyploid plant genomes. Further insights into the advances in our knowledge on plant domestication and evolution made through the use of DNA markers and genomic tools is provided in this paper.

Abstract: The coffee industry produces a wide range of organic wastes, some in large amounts, and most of them do not have a well-defined final disposal. The agricultural use of these wastes can be based on the recycling of nitrogen, but their chemical characterization and evaluation with soil under controlled conditions are mandatory. The aim of this work was to evaluate the use of coffee silverskin and expired coffee grounds as organic fertilizers. The wastes were chemically characterized according to CONAMA?S resolution No. 375 and passed through Brazil?s Agriculture Ministry regulation for organic fertilizers and soil conditioners. A greenhouse experiment with Rhodic Ferralsol soil and maize was performed to obtain the agronomic efficiency index (AEI) for nitrogen. The treatments were control (without residue), ammonium nitrate as a mineral reference, and both organic wastes, at a dose of 450 mg of Kjeldahl nitrogen per pot, in triplicate. The data obtained in the characterization were favorable to the wastes as nitrogen sources for agriculture. However, the AEIs obtained were low (0.5 and 7.9% for the expired coffee grounds and the coffee silverskin, respectively) compared to that of the mineral reference (92%). Based on these results, the use of coffee silverskin and expired grounds as organic fertilizers is not recommended but can improve soil attributes and serve as a complementary source of nitrogen and potash. ? Resumo: A indústria de café produz uma série de resíduos, sendo alguns em grande quantidade, a maioria dos quais sem uma disposição final bem definida. O uso agrícola destes resíduos pode se basear na reciclagem do nitrogênio (N), porém a caracterização química e a avaliação destes materiais em condições controladas no solo são obrigatórias. Portanto, o objetivo desse trabalho foi avaliar o uso agrícola da película de café e pó de café vencido como fertilizantes orgânicos. A caracterização química foi realizada segundo a resolução 375 do CONAMA e os resultados comparados com a legislação para fertilizantes do Ministério da Agricultura. Um experimento em casa de vegetação com amostras de um Latossolo Vermelho distrófico, utilizando o milho como planta teste, foi realizado para obtenção do Índice de Eficiência Agronômica (IEA) para nitrogênio. Três tratamentos foram utilizados: controle (sem resíduo), nitrato de amônio como referência mineral e os ambos os resíduos, na dose de 450 mg de nitrogênio Kjeldahl por vaso, em triplicata. Os dados da caracterização química calcularam-se os desvios padrões. Os resultados de caracterização foram favoráveis ao uso agrícola desses resíduos como fonte de nitrogênio, porém os IEAs obtidos foram baixos (0.5 e 7.9% para o pó e película de café respectivamente) quando comparados com a referência mineral (92%). Embora a película e o pó de café apresentem teores de nitrogênio acima do mínimo exigido pela instrução normativa (0,5% m/m), o uso como fertilizantes orgânicos (como fonte exclusiva de N) não é recomendada, visto que menos de 10% do N estava disponível como mostrado pelo IEA.
