Summary
Cultivated peanut (Arachis hypogaea) is a major oil and
protein crop, which is proposed to be formed by a crossing between Arachis duranensis and Arachis ipaensis. To date, several Arachis genomes have been de novo
assembled, including A. duranensis, A. ipaensis, A. monticola, A. hypogaea cv. Tifrunner, A.
hypogaea cv. Shitouqi, and A.
hypogaea cv. Fuhuasheng. However, the studies on mining functional genes
are tardily processing. In addition, cultivated peanut has a lower genetic
diversity relative to wild species. The genetic bottleneck leads to cultivated
peanuts with lower biotic and abiotic stresses. It is important to identify
tolerant/resistant genes in wild resources for cultivated peanut breeding in
the future.
More phenotypes have
been changed in cultivated peanuts after polyploidization compared to wild
peanuts. The phenotypes include chlorophyll content, stomatal size, and
follower color. Now, it has a reality to reveal the phenotypic changes at the
molecular level using genomic datasets in Arachis.
The scopes of the
special issue include:
1.
heredity basis and QTL mapping of the agronomy traits in Arachis.
2.
comparison of phenotypic variation and related genes analysis in Arachis.
3.
comparative genomics and gene family evolution analysis in Arachis.
4.
functional genes identification related to
growth and development in Arachis.
5.
functional genomics and genetic improvement studies
related to abiotic and biotic stress tolerance in Arachis.
