Drought stress is an important abiotic factor limiting common bean yield, with great impact on the production worldwide. Understanding the genetic basis regulating beans? yield and seed weight (SW) is a fundamental prerequisite for the development of superior cultivars. The main objectives of this work were to conduct genome-wide marker discovery by genotyping a Mesoamerican panel of common bean germplasm, containing cultivated and landrace accessions of broad origin, followed by the identification of genomic regions associated with productivity under two water regimes using different genome-wide association study (GWAS) approaches. A total of 11,870 markers were genotyped for the 339 genotypes, of which 3,213 were SilicoDArT and 8,657 SNPs derived from DArT and CaptureSeq. The estimated linkage disequilibrium extension, corrected for structure and relatedness (r2sv), was 98.63 and 124.18 kb for landraces and breeding lines, respectively. Germplasm was structured into landraces and lines/cultivars. We carried out GWASs for 100-SW and yield in field environments with and without water stress for 3 consecutive years, using single-, segment-, and gene-based models. Higher number of associations at high stringency was identified for the SW trait under irrigation, totaling ~185 QTLs for both single- and segment-based, whereas gene-based GWASs showed ~220 genomic regions containing ~650 genes. For SW under drought, 18 QTLs were identified for single- and segment-based and 35 genes by gene-based GWASs. For yield, under irrigation, 25 associations were identified, whereas under drought the total was 10 using both approaches. In addition to the consistent associations detected across experiments, these GWAS approaches provided important complementary QTL information (~221 QTLs; 650 genes; r2 from 0.01% to 32%). Several QTLs were mined within or near candidate genes playing significant role in productivity, providing better understanding of the genetic mechanisms underlying these traits and making available molecular tools to be used in marker-assisted breeding. The findings also allowed the identification of genetic material (germplasm) with better yield performance under drought, promising to a common bean breeding program. Finally, the availability of this highly diverse Mesoamerican panel is of great scientific value for the analysis of any relevant traits in common bean.

Os ecossistemas amazônicos são ricos em plantas com propriedades inseticidas e piscicidas, e as mais usadas na região pertencem ao gênero Derris. Desta forma, considerou-se importantes, neste trabalho, estudar as influencias e os efeitos de fatores relacionados as técnicas de cultura de tecidos vegetais, associados a nutrição mineral e a produção de metabolitos secundários, em duas especies de timbós. Vários experimentos foram conduzidos no Laboratório de Cultura de Tecidos Vegetais do Departamento de Agricultura da Universidade Federal de Lavras - UFLA, em Lavras, Minas Gerais. Os resultados obtidos permitiram a elaboração de protocolos para produção de calos a partir de explantes foliar e radical e de regeneração de plântulas de timbó. Calos oriundos de explante radical e Derris urucu, cultivados em meios nutritivos formulados com variações de concentrações dos sais de nitrogênio e de fósforo de 'MS', apresentaram respostas positivas para biossíntese de compostos rotenoides, os quais foram determinados por cromatografia liquida de alta eficiência (CLAE). Estes metabolitos secundários também foram determinados em sistema radicular de plântulas de D. urucu em condições de cultivo in vitro. Também são discutidos alguns aspectos da nutrição mineral de D. urucu de técnicas de diagnose por subtração. |
