Between Wishes and Beliefs in Wild Grapes

Among the desires and beliefs for wild grapes in 'wild grapes', Robert Frost shows the complex thoughts and fighting of women living in their lives. . At the same time, she wants to maintain an exciting way in her life. Through role explanation, metaphor, symbol, and terminology, Robert Frost knows that readers should prepare for their own life, but they are still listening to their heart, so they are ready to tell a lie Indicates that it is not. Before them.

We collected genome-wide re-sequencing data from table grapes, wine grapes, and putative wild grape samples to investigate group structure and demographic history. These analyzes lead to our initial conclusion that our Pinus sylvestris samples represent genuine wild grapes, not wild escapes. This conclusion can be confirmed from the population structure analysis of the Pinus sylvestris population presumed to be different from the cultivated grapes (Fig. 1), and the selected genes are presumed to be in grape seeds and hazelnuts (Fig. 2). There was a significant difference between pine samples (FIG. 3A). However, the difference between wild and cultivated samples is that of our Pinus sylvestris var. It suggests that mongolica does not represent the ancestral group of grapes probably tamed.

We will generate genome data to estimate the history of the population of grapes, the world's most economically important horticultural crops. Domesticated grapes experienced a long-term decline of 22000 years before acclimating; we think that this reduction reflects the low-intensity culture of humans before adaptation. Domestication changed the grape breeding system. The sex determination area can be detected as a region where the genetic difference between the wild type and the cultivated germplasm is increased. Based on gene expression analysis, we propose candidate genes that alter sex determination. Finally, grapes contain more harmful mutations in their heterozygous state than their wild ancestors. Accumulation of deleterious mutations is in part due to clonal expansion, which avoids harmful recessive mutations.
