Developmental Changes in Peanut Root Structure during Root …
Peanut (Arachis hypogaea) forms root nodules in a unique process. Structures of various peanut root types were studied with emphasis on insufficiently characterized lateral roots, changes in roots during their ontogenesis and root modification by nodule formation. Peanut plants were grown in the field, in vermiculite or in filter paper.
Transcriptome profiles reveal gene regulation of peanut
2017年1月6日 · In this study, the downstream symbiosis signaling pathway genes, NSP2, NIN, and ERN1 were found differentially expressed in nod+ lines, which indicated their role in peanut nodulation.
Nodule INception‐independent epidermal events lead to bacterial …
2022年9月13日 · Arachis hypogaea (peanut) is an economically important allotetraploid legume. Peanut can form root nodules with cognate Bradyrhizobium spp. Rhizobia enter peanut roots using developmental cracks, and generate aeschynomenoid-type nodules containing a uniform infection zone (Boogerd & van Rossum, 1997).
The genome of cultivated peanut provides insight into legume ... - Nature
2019年5月1日 · High oil and protein content make tetraploid peanut a leading oil and food legume. Here we report a high-quality peanut genome sequence, comprising 2.54 Gb with 20 pseudomolecules and 83,709...
Novel digital assessment technique used to describe peanut nodulation ...
2021年9月1日 · To provide an updated method of nodulation assessments, peanut (Arachis hypogaea L.) nodules were sampled from a two-year field trial and quantified using scanned images of excised nodules, allowing digital assessment of nodule number and size.
Transcriptomic and Metabolomic Analyses Reveal the Roles of …
2023年6月15日 · Peanut (Arachis hypogaea) is a leguminous crop whose nodulation mechanism requires further elucidation. In this study, comprehensive transcriptomic and metabolomic analyses were conducted to assess the differences between a non-nodulating peanut variety and a nodulating peanut variety.
The application of CRISPR/Cas9 in hairy roots to explore the …
2020年9月7日 · In this study, we conducted hairy root mediated CRISPR knockout of peanut AhNFR1 and AhNFR5 genes to characterize their functions in nodulation symbiosis. The results not only approved that CRISPR/Cas9 in coupled with hairy root transformation system is a rapid approach in characterizing gene functions in roots, but also improved our ...
Comparison of SNP Calling Pipelines and NGS Platforms to Predict …
2020年3月24日 · Results of this study mainly provide the pros and cons of NGS and SNP genotyping platforms for genetic mapping in peanut, and also provide potential genetic resources to narrow down the genomic regions controlling peanut nodulation, which would lay the foundation for gene cloning and improvement of nitrogen fixation in peanut.
Identified through a forward genetics approach, natural mutations in a pair of NSP2 homoeologs can cause loss of nodulation in peanut. Downloaded from...
