SQUAMOSA promoter-binding protein-like (SPL) proteins play crucial roles in plant growth, development, and responses to environmental stressors. The peanut (Arachis hypogaea L.) is a globally important oil crop. In this study, we cloned the full-length cDNA of 15 SPLs in the peanut by transcriptome sequencing and rapid amplification of cDNA ends, and analyzed their genomic DNA sequences. cDNA lengths varied significantly, from 369 to 3102 bp. The SBP domain of the peanut SPL proteins was highly conserved compared to SPLs in other plant species.

Crossability of Arachis valida and B genome Arachis species

D. C. Wondracek-Lüdke, Custodio, A. R., Simpson, C. E., and Valls, J. F. M., Crossability of Arachis valida and B genome Arachis species, vol. 14, pp. 17574-17586, 2015.

The peanut (Arachis hypogaea) is an important food crop in much of the tropical and semi-tropical parts of the world. The peanut is an allotetraploid with an AABB genome formula derived from diploids A. duranensis (A genome) and A. ipaënsis (B genome). The success of an introgression program that aims to improve cultivated varieties of the peanut depends on whether the chosen B genome species is homologous with the B genome of the peanut.

Performance of peanut mutants and their offspring generated from mixed high-energy particle field radiation and tissue culture

J. S. Wang, Qiao, L. X., Zhao, L. S., Wang, P., Guo, B. T., Liu, L. X., and Sui, J. M., Performance of peanut mutants and their offspring generated from mixed high-energy particle field radiation and tissue culture, vol. 14, pp. 10837-10848, 2015.

To develop new ways to breed peanut, we irradiated seeds of the Luhua 11 cultivar with a mixed high-energy particle field at different doses. The embryonic leaflets were extracted as explants and incubated on somatic embryo induction medium and then on somatic embryo germination and regeneration medium. After being grafted, the M1-generation plants were transplanted, and seeds from each M1-generation plant were harvested. In the following year, the M2-generation seeds were planted separately.
