In intercropping systems shading conditions significantly impair the seed yield and quality of soybean, rarely someone investigated minimum amount light requirement for soybean growth development. Therefore, it is an urgent need to determine threshold intensity ensure sustainable production under these systems. An integrated approach combining morphology, physiology, biochemistry genetic analysis was undertaken study effects on A pot experiment set up in a chamber increasing treatments 100...
Significance Overapplication of nitrogen (N) fertilizer causes delayed flowering and negatively impacts the function composition natural ecosystems climate. In this study, we demonstrate that time variations regulated by altered levels are mediated two key factors: ferredoxin-NADP + -oxidoreductase (FNR1) blue-light receptor cryptochrome 1 (CRY1). Nitrogen regulates FNR1 expression, thereby contributing to changes in NADPH/NADP ATP/AMP ratios, which turn activates adenosine...
The intensity and quality (red to far-red (R/Fr) ratio) of light directly affect growth plant under shading. Gibberellins (GAs) auxin [indole-3-acetic acid (IAA)] play important roles in mediating the shading adaptive responses plants. Thus, uncoupling from were assessed identify influence each component on morphology matter distribution leaf, stem, petiole. This assessment was based changes endogenous Gibberellin 1 (GA1) IAA levels. Soybean plants grown a chamber with four treatments...
Different planting patterns affect the light interception of intercrops under intercropping conditions. Here we revealed that narrow-wide-row relay-intercropping improves across maize leaves in wide rows (60cm) and narrow (40cm), accelerated biomass production intercrop-species compensated slight yield loss by considerably increasing soybean yield. In a two-year experiment, was planted with different (1M1S, 50:50cm 2M2S, 40:60cm) relay-intercropping, both were compared sole cropping (M) (S)....
Abstract Background Shading includes low light intensity and varying quality. However, a red/far-red (R/Fr) ratio of is signal that affects plant growth in intercropping close- planting systems. Thus, the R/Fr uncoupling from shading conditions was assessed to identify effect quality on photosynthesis CO 2 assimilation. Soybean plants were grown chamber with natural solar radiation under four treatments, is, normal (N, sunlight), N + Fr, Low (L) L light. Results significantly increased total...
Abstract Intercropping advantage occurs only when each species has adequate time and space to maximize cooperation minimize competition between them. A field experiment was conducted for two consecutive years 2013 2014 investigate the effects of maize soybean relay strip intercropping systems on uptake utilization nitrogen, phosphorus, potassium. The treatments included “40:160” (T1, narrow wide row spacing 40 160 cm, where rows with a cm were planted in rows. area occupation ratio both 50%...
Soybean is an important oilseed crop grown globally. However, two examples of environmental stresses that drastically regulate soybean growth are low light and high-temperature. Emerging evidence suggests a possible interconnection between these stimuli. Low high-temperature as individual factors have been reported to plant hypocotyl elongation. their interactive signal effect on development remains largely unclear. Here, we report gibberellins (GAs) auxin required for elongation under...
Soybean production under maize–soybean relay-intercropping system (MSICS) is vulnerable to shading. A study was initiated investigate the effects of three sowing-times: ST1, 90; ST2, 70; and ST3, 50 days co-growth period two phosphorus-rates: P0, 0; P60, 60 kg P ha−1 on soybean MSICS. Results revealed that ST3 significantly increased photosynthetically active radiations, leaf area index, photosynthetic rate by 72% 58%, 61% 38%, 6% 8%, respectively, at full-flowering full-pod stage than ST1....
The effect of shading during seed development on subsequent germination remains largely unknown. In this study, two soybean (Glycine max) production systems, monocropping (MC) and maize-soybean intercropping (IC), were employed to examine the effects mother plant germination. Compared MC seeds, which received light, developing IC seeds exposed shade resulting from taller neighboring maize plants. germinated faster than although there was no significant difference in thickness coat....
Melatonin (MT) regulates several physiological activities in plants. However, information on how MT soybean growth under low-temperature (LT) stress is lacking. To better understand promotes plant and development LT stress, we designed this study to evaluate the role of pretreatment seedlings exposed stress. Our results showed that increased oxidative damage by increasing reactive oxygen species (ROS) accumulation, which affected seedlings. application 5 µmol L-1 significantly decreased...
Nitric oxide (NO) is extensively involved in various growth processes and stress responses plants; however, the regulatory mechanism of NO-modulated cellular sugar metabolism still largely unknown. Here, we report that NO significantly inhibited monosaccharide catabolism by modulating metabolic enzymes through S-nitrosylation (mainly oxidizing dihydrolipoamide, a cofactor pyruvate dehydrogenase). These modifications led to decrease glycolysis ATP synthase activities as well declines content...
Oilseed rape (Brassica napus) is a Cadmium (Cd) hyperaccumulator. However, high-level Cd at the early seedling stage seriously arrests growth of rape, which limits its applications. Brassica juncea had higher accumulation capacity, but biomass was lower, also limiting Previous studies have confirmed that Selenium (Se) can alleviate toxicity. regulatory mechanism Se in different valence states unclear. In this study, we investigated ameliorating effects three states, Na2SeO4 [Se(VI)], Na2SeO3...
Plants use shade avoidance strategy to escape the canopy when grown under natural conditions. Previous studies showed that Arabidopsis receptor-like kinase ERECTA (ER) is involved in syndrome. However, mechanisms of ER modulating SAR by promoting hypocotyl elongation are unknown yet. Here we report regulated requires auxin and gibberellins (GAs). The T-DNA insertional mutant er-3 shows a less length than Col-0 wild type. Promoter::GUS staining analysis its paralogous genes ERECTA-LIKE1...

The relationship between Mg-protoporphyrin IX (Mg-Proto IX) signals and plant's tolerance to cold stress is investigated. Arabidopsis seedlings grown for 3 weeks were pretreated with 2 mM glutamate MgCl2 48 h at room temperature induce Mg-Proto accumulation. Then was performed 4 °C additional 72 h. Glutamate + pre-treatments alleviated the subsequent significantly by rising leaf through inducing signals. protective role of treatment greatly compromised in mutants synthesis, signaling...
After nitrogen treatments, plant leaves become narrower and thicker, the chlorophyll content increases. However, molecular mechanisms behind these regulations remain unknown. Here, we found that changes in leaf width thickness were largely compromised shade avoidance 3 (sav3) mutant. The SAV3 gene encodes an amino-transferase auxin biosynthesis pathway. Thus, crosstalk between Arabidopsis development was investigated. Both hypocotyl elongation expansion promoted by treatment reduced high-N...
Leaf veins constitute the transport network for water and photosynthetic assimilates in vascular plants. The class III homeodomain-leucine zipper (HD-Zip III) gene family is central to regulation of development. In this research, we performed an overall analysis HD-Zip genes soybean (Glycine max L. Merr.). Our included phylogeny, conservation domains cis-elements promoters these genes. We used quantitative reverse transcription-polymerase chain reaction characterize expression patterns leaf...
