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 ... more

genetic relationships; Groundnut; Microsatellites; peanut; Simple sequence repeat

The Kayabi Indians who inhabit the Xingu Indigenous Park, located in West Central Brazil, have grown and managed peanuts for a long time. A great number of landraces are being maintained by these tribes and some of this germplasm has morphological traits that exceed the variation described in the taxonomic literature. Here, we analyzed the genetic variability of these landraces using a ... more

3-glucanase gene; Arachis hypogaea L.; Disease resistance; Genetic transformation; peanut; Vector construction; β-1

Plant β-1,3-glucanases are commonly involved in disease resistance. This report describes the cloning and genetic transformation of a β-1,3-glucanase gene from peanut. The gene was isolated from both the genomic DNA and cDNA of peanut variety Huayu20 by polymerase chain reaction (PCR) and reverse transcription PCR (RT-PCR), respectively. The DNA sequence contained 1471 bp including two ... more

Allene oxide cyclase gene; Gene cloning; Overexpression; peanut; Salt stress

In this study, the full-length cDNA encoding allene oxide cyclase (AhAOC) was isolated from peanut (Arachis hypogaea L.). The deduced amino acid sequence of AhAOC showed high homology with other plant AOCs. The transcript of AhAOC was found to be abundantly expressed in roots. Expression analysis demonstrated that AhAOC was induced by abscisic ... more

Hypoxia-inducible factor-2 alpha (HIF-2α) has been shown to regulate cell stemness, although the expression and effects of HIF-2α in lung cancer stem cells remained unclear. This study investigated HIF-2α expression in lung cancer stem cells, as well as the relationship between HIF-2α expression and radioresistance in lung cancer cells. Stem-like cells (CD133+) in the non- ... more

Callus; Fusarium graminearum crude toxin; In vitro culture; Superoxide dismutose; Wheat mature embryo

Five wheat varieties with different resistance to scab were used to study the effect of Fusarium graminearum crude toxin on culture characteristics of mature wheat embryos in vitro. The results showed that the rate of induction and differentiation of mature embryo callus differed significantly between varieties, toxin concentration, and concentration x varieties. A low ... more

Gene expression; peanut; Pod development; SQUAMOSA promoter-binding protein-like protein

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 ... more

Gynophore; MicroRNA sequencing; peanut

Peanut is one of the most important oilseed crops in the world that provides a significant amount of lipids and protein for many people. The gynophore plays an important role in gynophore development after fertilization of the peanut ovule. MicroRNAs (miRNAs) play an important role in numerous developmental and physiological plant ... more
