Abstract Chlorophyll meters are widely used to guide nitrogen (N) management by monitoring leaf N status in agricultural systems, but the effects of environmental factors and characteristics on estimations still unclear. In present study, we estimated relationships among SPAD readings, chlorophyll content per area for seven species grown multiple environments. There were similar between readings groups, relationship varied groups. A significant impact light-dependent chloroplast movement was...
Human selection has a long history of transforming crop genomes. Peach (Prunus persica) undergone more than 5000 years domestication that led to remarkable changes in series agronomically important traits, but genetic bases underlying these and the effects artificial on genomic diversity are not well understood.Here, we report comprehensive analysis peach evolution based genome sequences 480 wild cultivated accessions. By focusing set quantitative trait loci (QTLs), provide evidence...
To identify the effect of nitrogen (N) nutrition on photosynthetic efficiency and mesophyll conductance rice seedlings (Oryza sativa L., cv. 'Shanyou 63' hybrid indica China), hydroponic experiments with different concentrations N were conducted in a greenhouse. Although leaf concentration dry mass basis increased increasing supply N, no significant differences seedling biomass observed. A higher light-saturated CO2 assimilation rate (A) high supplied was associated carboxylation (CE), but...
Photosynthesis in C3 plants is significantly limited by mesophyll conductance (gm ), which can vary with leaf anatomical traits and nitrogen (N) supplements. Several studies have investigated the response of gm to N supplements; however, none examined implications supplements on rapid environmental changes. Here we effect supplement change CO2 , temperature irradiance rice. High (HN) increased cell wall surface area chloroplast exposed intercellular airspace per area, reduced thickness....
High nitrogen (N) supply frequently results in a decreased photosynthetic N-use efficiency (PNUE), which indicates less efficient use of accumulated Ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco). Chloroplasts are the location Rubisco and endpoint CO2 diffusion, they play vital important role photosynthesis. However, effects chloroplast development on photosynthesis poorly explored. In present study, rice seedlings (Oryza sativa L., cv. 'Shanyou 63', 'Yangdao 6') were grown...
Leaf hydraulic conductance (Kleaf) is a major determinant of photosynthetic rate in plants. Previous work has assessed the relationships between leaf morpho-anatomical traits and Kleaf with woody species, but there been very little focus on cereal crops. The genus Oryza, which includes rice (Oryza sativa) wild species (such as O. rufipogon cv. Griff), ideal material for identifying features associated gas exchange. traits, Kleaf, N content per area, CO2 diffusion efficiency were investigated...
Summary A host‐plant and its associated microbiota depend on one another. However, the assembly process functioning of host‐associated are poorly understood. Herein, rice was used as model plant to investigate assemblage bacterial microbiota, including those in seed, root endosphere rhizosphere. We also assessed degree which rhizosphere communities were influenced by vertical transmission through seed identified core microbes that potentially with phenotypic properties. Plant microhabitat,...
Stay-green, a key trait of wheat, can not only increase the yield wheat but also its resistance to heat stress during active photosynthesis. Cytokinins are most potent general coordinator between stay-green and senescence. The objectives present study were identify assess effects cytokinins on photosynthetic organ in wheat. Two winter cultivars, Wennong 6 (a cultivar) Jimai 20 control cultivar), subjected treatment from 1 5 days after anthesis (DAA). two cultivars sprayed daily with 10 mg...
Root system architecture is very important for plant growth and crop yield. It essential nutrient water uptake, anchoring, mechanical support. angle (RGA) a vital constituent of root used as parameter variety evaluation in breeding. However, little known about the underlying molecular mechanisms that determine rice (Oryza sativa). In this study, mutant large angle1 (lra1) was isolated shown to exhibit RGA reduced sensitivity gravity. Genome resequencing complementation assays identified...
Abstract The rapid response of stomatal conductance (gs) to fluctuating irradiance is great importance maximize carbon assimilation while minimizing water loss. Smaller stomata have been proven a faster rate than larger ones, but most these studies conducted with forest trees. In the present study, effects anatomy on kinetics gs and photosynthesis were investigated in 16 Oryza genotypes. Light-induced opening includes an initial time lag (λ) followed by exponential increase. had maximum...
Abstract Studies investigating the mechanisms underlying variation of photosynthesis along plant phylogeny and especially during domestication are great importance, may provide new insights to further improve crop photosynthesis. In present study, we compiled a database including 542 sets data leaf gas exchange parameters structural chemical traits in ferns fern allies, gymnosperms, non-crop angiosperms, crops. We found that was dramatically improved from allies increased The improvement...
Stigma and spikelet characteristics play an essential role in hybrid seed production. A mini-core of 90 accessions developed from USDA rice core collection was phenotyped field grown for nine traits stigma genotyped with 109 DNA markers, 108 SSRs plus indel. Three major clusters were built upon Rogers' genetic distance, indicative indicas, temperate tropical japonicas. mixed linear model combining PC-matrix K-matrix adapted mapping marker-trait associations. Resulting associations adjusted...
Previous studies demonstrated that ammonium nutrition results in higher water uptake rate than does nitrate under stress, and thus enhances the tolerance of rice plants to stress. However, process by which is related nitrogen form stress remains unknown. A hydroponic experiment with simulated induced polyethylene glycol (PEG6000) was conducted a greenhouse study relationship between root aerenchyma formation rate, such as xylem sap flow hydraulic conductance, two different cultivars (cv....
Abstract To identify the effect of nitrogen (N) nutrition on dynamic photosynthesis rice plants, a pot experiment was conducted under two N conditions. The leaf and chlorophyll levels, as well steady–state photosynthesis, were significantly increased high N. After transition from saturating to low light decreases in induction state ( IS %) A ) stomatal conductance g s more severe than supply. flecked irradiance, times 90% maximum (T longer Under max–fleck min–fleck both lower those uniform...
The present study was performed to evaluate the effects of seed priming. This done by soaking seeds two rapeseed cultivars, namely, ZY15 (tolerant low temperature and drought) HY49 (sensitive drought), for 12 h in varying solutions: distilled water, 138 mg/L salicylic acid (SA), 300 gibberellic (GA), 89.4 sodium nitroprusside (SNP), 3000 calcium chloride (CaCl2), 30 abscisic (ABA). Primed non-primed were left germinate at 15°C -0.15 MPa (T15W15) 25°C 0 (T25W0), respectively. results showed...
The environment has constantly shaped plant genomes, but the genetic bases underlying how plants adapt to environmental influences remain largely unknown. We constructed a high-density genomic variation map of 263 geographically representative peach landraces and wild relatives. A combination whole-genome selection scans genome-wide association studies (GWEAS) was performed reveal adaptation diverse climates. total 2092 selective sweeps that underlie local both mild extreme climates were...
