Background and AimsOne of the key targets breeding programmes in rapeseed (Brassica napus) is to develop high-yield varieties. However, lack available phosphorus (P) soils seriously limits production. The aim this study was dissect genetic control seed yield yield-related traits B. napus grown with contrasting P supplies.
Maintaining an appropriate balance of carbon to nitrogen metabolism is essential for rice growth and yield. Glutamine synthetase a key enzyme ammonium assimilation. In this study, we systematically analyzed the phenotype, carbon-nitrogen metabolic status gene expression profiles in GS1;1-, GS1;2-overexpressing wildtype plants. Our results revealed that plants exhibited poor plant phenotype yield decreased carbon/nitrogen ratio stem caused by accumulation stem. addition, leaf SPAD value...
Allotetraploid rapeseed (Brassica napus L., An Cn , 2n = 4x 38) is extraordinarily susceptible to boron (B) deficiency, a ubiquitous problem causing severe losses in seed yield. The breeding of B-efficient germ plasm cost-effective and environmentally friendly strategy for the agricultural industry; however, genes regulating B efficiency allotetraploid have not yet been isolated. In this research, quantitative trait locus (QTL) fine mapping digital gene expression (DGE) profiling were...
Boron (B) is an essential micronutrient for plants, but the molecular mechanisms underlying uptake and distribution of B in allotetraploid rapeseed (Brassica napus) are unclear. Here, we identified a transporter rapeseed, BnaC4.BOR1;1c, which expressed shoot nodes involved distributing to reproductive organs. Transgenic Arabidopsis plants containing BnaC4.BOR1;1c promoter-driven GUS reporter gene showed strong activity roots, nodal regions shoots immature floral buds. Overexpressing wild...
Nitrogen (N) is a critical factor for crop growth and yield. Improving N use efficiency (NUE) in agricultural systems crucial sustainable food production. However, the underlying regulation of uptake utilization crops not well known. Here, we identified OsSNAC1 (stress-responsive NAC 1) as an upstream regulator OsNRT2.1 (nitrate transporter 2.1) rice (Oryza sativa) by yeast 1-hybridization screening. was mainly expressed roots shoots induced deficiency. We observed similar expression...
Transcription factors regulating crop uptake and translocation of the micronutrient Cu have not been identified. We isolated a novel R2R3-MYB transcription factor, OsMYB84, showed that it was positive regulator involved in transport via activation OsCOPT2 OsHMA expression. OsMYB84 highly expressed roots anthers induced by Cu. Overexpression promoted root-to-shoot rice, facilitated distribution into grain increased yield. In contrast, mutation reduced concentration xylem sap. bound to...
Oilseed rape (Brassica napus) is an important oil crop worldwide. The aim of this study was to identify the variation in nitrogen (N) efficiency new-type B. napus (genome ArArCcCc) genotypes, and characterize some critical physiological molecular mechanisms response N limitation. Two genotypes with contrasting (D4-15 D1-1) were identified from 150 lines, hydroponic pot experiments conducted. Root morphology, plant biomass, uptake parameters seed yield D4-15 D1-1 investigated. traditional...
Glutamine synthetase 2 (GS2) is a key enzyme involved in the ammonium metabolism plant leaves. In our previous study, we obtained GS2-cosuppressed plants, which displayed normal growth phenotype at seedling stage, while tillering stage they showed chlorosis phenotype. this to investigate mechanism, systematically analyzed growth, carbon-nitrogen and gene expressions between rice wild-type plants. The results revealed that plants exhibited poor nitrogen transport ability, led accumulation...
Phosphate (Pi) transporters play critical roles in Pi acquisition and homeostasis. However, little is known about these oilseed rape. Therefore, the aim of present study was to characterize members PHT1 gene family allotetraploid Brassica napus analyze their expression profiles response environmental stresses. In total, 49 were identified B. napus, including 27 genes A subgenome 22 C subgenome. Most proteins predicted localize plasma membrane. Phylogenetic analysis suggested that can be...
Abstract Considerable genetic variation in agronomic nitrogen (N) use efficiency (NUE) has been reported among genotypes of Brassica napus . However, the physiological and molecular mechanisms underpinning these differences remain poorly understood. In this study, factors impacting NUE were identified field trials hydroponic experiments using two B. with contrasting NUE. The results showed that N‐efficient genotype (D4‐15) had greater N uptake utilization efficiencies, more root tips, larger...
Breeding crops with ideal root system architecture for efficient absorption of phosphorus is an important strategy to reduce the use phosphate fertilizers. To investigate genetic variants leading changes in architecture, 405 oilseed rape cultivars were genotyped a 60K Brassica Infinium SNP array low and high P environments. A total 285 single-nucleotide polymorphisms associated traits at varying levels. Nine corroborate previous linkage analysis quantitative trait loci BnaTNDH population....
Phytohormones play pivotal roles in the response of plants to various biotic and abiotic stresses. Boron (B) is an essential microelement for plants, Brassica napus (B. napus) hypersensitive B deficiency. However, how auxin responds deficiency remained a dilemma many years little known about other phytohormones respond The identification B-efficient/inefficient B. indicates that breeding might overcome these constraints agriculture production. Here, we seek identify phytohormone-related...
Allotetraploid rapeseed ( Brassica napus L. A n C , 2 =4 x =38) is highly susceptible to boron (B) deficiency, a widespread limiting factor that causes severe losses in seed yield. The genetic variation the sensitivity B deficiency found genotypes emphasizes complex response architecture. In this research, B-inefficient genotype, 'Westar 10' ('W10'), responded deficiencies during vegetative and reproductive development with an over-accumulation of reactive oxygen species, lipid peroxidation,...
Brassinosteroids (BRs) are pivotal phytohormones involved in the control of root development. Boron (B) is an essential micronutrient for plants, and growth rapidly inhibited under B deficiency conditions. However, mechanisms underlying this inhibition still unclear. Here, we identified BR-related processes at physiological, genetic, molecular/cell biological transcriptomic levels found strong evidence that can affect BR biosynthesis signalling, thereby altering growth. RNA sequencing...
Phosphorus (P) deficiency is one of the major limitations for crop production. A significant relationship exists between plant P uptake from soils and accumulation other mineral elements in seeds. The aims this study were to identify characterize genetic loci (QTLs) controlling seeds Brassica napus grown with contrasting availabilities. population 124 recombinant inbred lines derived a cross P-inefficient 'B104-2' P-efficient 'Eyou Changjia' was used phenotypic investigation QTL analysis....
The importance of SPX domain-encoding proteins to phosphate (Pi) homeostasis and signaling pathways has been well-documented in rice Arabidopsis. However, global information responses members P stress allotetraploid Brassica napus, one the world's major oil crops that is sensitive deficiency, remain undefined. We identified a total 69 domain-containing genes B. napus genome. Based on domain organizations, these were classified into four distinct subfamilies—SPX (11), SPX-EXS (43), SPX-MFS...
