Selection Of

The sweet potato (Ipomoea batatas (l.) Lam.) Lam) is a plant that produces tuberous root belonging to the family convolvulácea explored in practically all states of Brazil. The objective of this work was to select genotypes of the sweet potato as the efficiency of phosphorus use in cerrado soils with high and low availability of this nutrient. Were evaluated nine genotypes of sweet potato coming from the germplasm bank from the Federal University of the Tocantins, Brazil. The experimental design was in randomized block design with three replications being nine genotypes grown in two environments with low and high phosphorus availability, using doses of phosphorus fertilization from 20 and 120 kg ha-1 P2O5, applied at planting. To select genotypes suitable for environments proposed was used methodology for selection of the efficient use and response to phosphorus fertilization (efficiency and response). Genotype Amanda was classified as efficient and responsive, Barbara, Julia, Marcela and Carolina Vitoria as efficient, but not responsive and Livia, Duda, Ana Clara and Beatriz were classified as non-efficient, responsive but the absorption and utilization of phosphorus.

Sequence Variations

Knowledge of genetic variations can provide clues into the molecular mechanisms regulating key crop traits. Sweet potato (Ipomoea batatas (L.) Lam.) is an important starch-producing crop, but little is known about the genetic variations in starch biosynthesis and sucrose metabolism genes. Here, we used high-throughput sequencing of pooled amplicons of target genes to identify sequence variations in 20 genes encoding key enzymes involved in starch biosynthesis and sucrose metabolism in 507 sweet potato germplasms. After filtering potential variations between gene copies within the genome, we identified 622 potential allelic single nucleotide polymorphisms (SNPs) and 85 insertions/deletions (InDels), including 50 non-synonymous SNPs (nsSNPs) and 12 frameshift InDels. Three nsSNPs were confirmed to be present in eight sweet potato varieties with various starch properties using cleaved amplified polymorphic sequence (CAPS) markers. Gene copy with loss of the fifth intron was detected in IbAGPb3 genes, and loss of multiple introns were observed in IbGBSS1-1 genes and various among germplasms based on intron length polymorphism (ILP) markers. Thus, we identified sequence variations between germplasms in 20 genes involved in starch biosynthesis and sucrose metabolism, and demonstrated the diversity in intron-loss alleles among sweet potato germplasms. These findings provide critical genetic information and useful molecular markers for revealing regulatory mechanism of starch properties.
