It is likely that the cultivated peanut derived from crossing of wild diploid species and underwent subsequent genome duplication [ 4, 5].
The name Peanuts is derived from the term "peanut gallery", which describes the cheap seats in a theatre.
Three mapping populations of recombinant inbred lines (RILs) of cultivated peanuts were derived from three crosses with a common female parent, Yueyou 13 (Y13), a Spanish bunch type with high yield.
The striking difference of polymorphism between the peanut SSRs derived from the two sources is consistent with differences reported in other crops.
In fact, autotetraploid-like tetrasomic recombination is surprisingly frequent in recombinant inbred lines generated from a cross of cultivated peanut and an induced allotetraploid derived from peanut's most probable ancestral species.
In peanut, differences in gene content were observed between the diploid A genome BAC (ADH35P21) and the tetraploid peanut BAC (AHF85I19) derived from the A genome (region between genes 5 7, 13 14, and 17 25 [ fig. 8]).
In contrast to the recurrent formation of several polyploid species, the allopolyploid structure of cultivated peanut is likely derived from a single hybridization between two wild diploid species followed by chromosome doubling [ 8].
To investigate the genetic behavior and genome structure of the peanut, we have over some years built up data sets centered around the two most probable diploid ancestral species of cultivated peanut, an induced allotetraploid derived from them, cultivated peanut, and RILs derived from a cross between them (Shirasawa et al. 2013; Bertioli et al. 2014; unpublished data).
Yams, plantains, and peanuts (groundnuts) are also important to the Yaunde economy, the latter so much so that the name Éwondo is derived from peanut.
He et al. developed a supercapacitor with mesoporous carbon derived from peanut biomass using ZnCl2 activation assisted microwave heating46.
Ding et al. recently reported both cathode and anode material of a hybrid sodium ion capacitor derived from peanut shell38.
