Article Synopsis
- There are different biotypes of the soybean aphid, Aphis glycines, in North America that can survive on soybeans with varying resistance traits known as Rag, but the genetic reasons for their virulence are not fully understood.
- A study using whole genome sequencing identified between 167,249 and 217,750 single nucleotide polymorphisms (SNPs) differentiating an avirulent biotype (B1) from three virulent biotypes (B2, B3, B4), highlighting specific regions associated with virulence.
- Findings suggest that a small number of genomic regions may play a significant role in the virulence of A. glycines, particularly those
Article Synopsis
- The soybean aphid (Aphis glycines) is a significant pest affecting soybeans, an important global crop; researchers sequenced the genome of a North American biotype to understand its biology.
- About 20.4% of its proteins are duplicated, with many related to apoptosis, suggesting adaptations to environmental stressors, with some duplicated genes also found in other aphid species.
- Population studies reveal that North American aphids are genetically similar to those from China and South Korea, with reduced diversity over time, and specific populations exhibit a greater ability to infest resistant soybean varieties.
The complete mitochondrial genome of the soybean aphid (Aphis glycines Matsumura), a major agricultural pest in the world, is described for the first time, which consists of 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, as well as a large repeat region between tRNA-Glu and tRNA-Phe, and an AT-rich control region. The 17,954 bp mtgenome is the largest reported from the family Aphididae, and its gene order follows the ancestral insect mtgenome except for the repeat region, which contains a 195 bp unit repeated 11.9 times, representing the highest reported repeats among the known aphid mtgenomes to date.
