Because plant mechanical strength influences growth and development, the regulatory mechanisms underlying cell-wall synthesis deserve investigation. Rice mutants are useful for such research. We have identified a novel brittle culm 25 (bc25) mutant with reduced partial sterility. BC25 encodes an UDP-glucuronic acid decarboxylase involved in cellulose belongs to UXS family. A single-nucleotide mutation accounts its altered cell morphology composition. Transmission electron microscopy analysis...
Abstract Resveratrol, a stilbene phytoalexin in plants, is believed to benefit human health. In this study, an optimized enzyme‐assisted method was developed extract the total content of trans ‐resveratrol (free or combined with glucose) peanut seeds, followed by detection using high‐performance liquid chromatography. The extraction process Box–Behnken design and response surface methodology. enzyme concentration, digestion time, pH, temperature were 3.02 g/L, 57.06 min, 5.88, 51.05°C,...
Two novel and adjacent genomics candidate genes for bacterial wilt resistance were identified on chromosome B02 in peanut variety Zhonghua 6 using both traditional QTL mapping QTL-seq methods. Peanut (Arachis hypogaea) is an important oilseed crop worldwide. Utilization of genetic the most economic effective approach to control wilt, one devastating plant diseases, production. To accelerate improvement (BWR) breeding programs, quantitative trait locus (QTL) has been conducted two resistant...
Grain size, grain number per panicle, and weight are key agronomic traits that determine yield in rice. However, the molecular mechanisms coordinately controlling these remain largely unknown. In this study, we identified a major QTL, SMG3, is responsible for rice, which encodes MYB-like protein. The SMG3 allele from M494 causes an increase of grains panicle but produces smaller size thousand weight. constitutively expressed various organs protein located nucleus. Microscopy analysis shows...
Summary The annual planting area of major inbred rice ( Oryza sativa ) cultivars reach more than half the total in China. However, how changed during decades genetic improvement and why they can be prevalently cultivated China remains unclear. Here, we investigated underlying changes contributions landraces introduced by resequencing a collection 439 accessions including cultivars, landraces, cultivars. results showed that were main contribution sources Xian Indica while Geng Japonica...
Accurately identifying varieties with targeted agronomic traits was thought to contribute genetic selection and accelerate rice breeding progress. Genomic (GS) is a promising technique that uses markers covering the whole genome predict genomic-estimated values (GEBV), ability select before phenotypes are measured. To choose appropriate GS models for work, we analyzed predictability of nine measured from population 459 diverse varieties. By comparison eight representative models, found...
Grain size and flag leaf angle are two important traits that determining grain yield in rice. However, the mechanisms regulating these remain largely unknown. In this study, a rice long 5 (lg5) mutant with large was identified, map-based cloning revealed single base substitution followed by 2 bp insertion LOC_Os05g40384 gene resulted larger grains, angle, higher plant height than wild type. Sequence analysis lg5 is novel allele of elongated uppermost internode-1 (EUI1), which encodes...
Using a field plot experiment method, the effects of intercropping three leguminous green fertilizer varieties (i.e., Chamaecrista rotundifolia (Pers.) Greene, Vigna sesquipedalis, and Indigofera hendecaphylla Jacq.) on fruit appearance, nutritional quality, soil erosion in topsoil layer, basic fertility navel orange orchard were studied, with no treatment as control. The results showed that those orchard, compared to control treatment, vertical diameter increased by 3.34%~11.35%, horizontal...
<p indent=0mm>Edible peanut is one of the important directions breeding in China and even world. However, lack efficient detection method soluble sugar content related to edible quality kernel limits progress breeding. In this study, a extracting from by 80% ethanol water bath was established. The simplified pre-treatment steps samples speeded up extraction compared with GB method. accuracy repeatability tests showed that had high effectiveness. Then, extracted were both tested HPLC-RID, it...
