Abstract

Since the 19^th century to date, the fungal pathogens have been involved in causing devastating diseases in plants. All types of fungal pathogens have been observed in important agricultural crops that lead to significant pre and postharvest losses. The application of synthetic fungicide against the fungal plant pathogens (FPP) is a traditional management practice but at the same time these fungicides kill other beneficial microbes, insects, animal, and humans and are harmful to environment. The antagonistic microorganism such as bacteria are being used as an alternate strategy to control the FPP. These antagonistic species are cost-effective

Abstract Putrescine (Put) as the compound of plant polyamines is catalyzed by arginine decarboxylase (ADC), which is encoded by two members, ADC1 and ADC2 in Arabidopsis, and ADC2 is mainly responsible for Put biosynthesis. Accumulated evidence demonstrates the important function of Put in plant growth and development, but its role in regulating seed germination under high temperature (HT) has not been reported yet. SOMNUS (SOM) is the negative regulator for seed germination thermoinhibition by altering downstream gibberellin (GA) and abscisic acid (ABA) metabolism. In this study, we found exogenous application of Put obviously alleviated the inhibition effect… More >

Abstract Allantoin as the metabolite of purine catabolism can store and remobilize nitrogen for plant growth and development. However, emerging evidence suggests it also contributes to plant tolerance to stress response through altering abscisic acid (ABA) and reducing reactive oxygen species (ROS) level. 1-CYS PEROXIREDOXIN (PER1) is a seed-specific antioxidant that enhances seed longevity through scavenging ROS over-accumulation. High temperature (HT) suppresses seed germination and induces seed secondary dormancy, called as seed germination thermoinhibition. However, the mechanism that allantoin and PER1 regulate seed germination thermoinhibition remains unknown. In this study, we reported that allantoin treatment enhances seed… More >

Abstract Bacterial leaf blight (BLB) caused by Xanthomonas oryzae pv. oryzae (Xoo) is one of the most damaging diseases to rice across the world. Various chemicals have been employed so far for the management of bacterial leaf blight. On the other hand, these compounds are damaging to the ecosystem and have an impact on non-target species such as humans and animals. As a result, there is a need to create a new natural inhibitor for BLB management. Deformylase (PDF) enzyme is present in all eubacteria and its necessity in bacterial protein synthesis reveals it as an attractive target… More >

Abstract Indoleacetic acid (IAA) is an important regulator that plays a crucial role in plant growth and responses to abiotic stresses. In the present study, a sand cultivation experiment was carried out to investigate the effects of IAA at different concentrations (0, 0.01, 0.1, 0.5, 1, and 2.5 mmol/L) on maize growth, root morphology, mineral elements (Ca, Mg) and Cd uptake under 20 mg/kg Cd stress. The results showed that 0.01 mmol/L is the optimal IAA concentration for enhancing the Cd tolerance of maize. Compared with the control treatment, 0.01 mmol/L IAA promoted maize growth, with… More >

Abstract

The embryos of maize (Zea mays L.) inbred lines GS02, GS07, GS08, GS11 and GS15 were used as receptor materials to optimize the receptor system from the aspects of genotype, medium components and stress (PEG6000, mannitol, salt and low phosphorus). The results showed that GS07 had the highest induction rate (95.2%). Orthogonal test analysis showed that the best combination of medium components in induction was A₂B₃C₁D₃₍₂₎, namely, the concentration of 2, 4-dichlorophenoxy acetic acid (2,4-D) was 4 mg·mL^-1, the concentration of L-Proline (L-Pro) was 0.8 mg·mL^-1, and the concentration of silver nitrate (AgNO₃) was 10 mg·mL^-1 (or 5 mg·mL).

Abstract Due to the unpredictable climate change, drought stress is being considered as one of the major threats to crop production. Wheat (Triticum aestivum L. cv. BARI Gom-26) being a dry season crop frequently faces scarcity of water and results in a lower yield. Therefore, this experiment aims to explore the role of different organic amendments (OAs) in mitigating drought stress-induced damage. The pot experiment consisted of different organic amendments viz. compost, vermicompost and poultry manure @0.09 kg m⁻² soil, biochar @2.5% w/w soil and chitosan @1% w/w soil which was imposed on the plants grown under both… More >

Abstract Polyploid plants grow well, are stress tolerant, and are rich in nutrients and bioactive compounds. Thus, they are useful for improving crop quality and yield. In this study, we compared the seed characteristics and metabolite profiles of diploid and tetraploid tartary buckwheat, which was developed via an artificially induced chromosome doubling event. The length, width, area, and thousand-grain weight were greater for the tetraploid seeds than for the diploid seeds. However, the germination rate decreased for the tetraploid seeds. Additionally, there was a gap between the shell and kernel of the tetraploid seeds. Moreover, the… More >

Abstract

The current work was performed to know the impact of cadmium (Cd) toxicity on two different genotypes of chickpea (Cicer arietinum L.) namely Pusa-BG1053 and Pusa-BG372. Cadmium was applied in the form of cadmium chloride (CdCl₂), in varying levels, 0, 25, 50, 75, and 100 mg Cd kg^-1 soil. Plant growth as well as physiological attributes were decreased with increasing concentration of Cd. Both genotypes showed the maximum and significant reduction at the maximum dose of Cd (100 mg Cd kg^-1 soil). Results of this study proved that the genotype Pusa-BG1053 was more tolerant and showed a lower

Abstract The ornamental and commercial values of herbaceous peony (Paeonia lactiflora Pall.) are directly related to its flower pattern. However, the molecular mechanisms underlying the type formation of P. lactiflora flowers have not been studied in great detail. Previous studies identified, using integrated multipleomics analysis, revealed that APETALA2 (AP2) is an important candidate gene that modulates type formation of P. lactiflora flowers. To further reveal the expression mechanism of AP2 in P. lactiflora petals, we examined the profile of AP2 expression in the inner and outer petals of ‘ZiFengyu’ at various developmental stages using qRT-PCR and BSP+Miseq methylation analysis.

Abstract Herbaceous peony (Paeonia lactiflora Pall.) is an important ornamental plant worldwide. In its natural state, P. lactiflora often manifests traits like rapidly elongating internodal growth, loose plant types, and soft inflorescence stems. However, very little has been known about the measures for controlling these traits. This study investigated the effect of applying paclobutrazol (PBZ) on the plant growth and flower quality in P. lactiflora. The results indicated that PBZ application reduced the plant height (8.05%), plant crown width (14.72%), and leaf area (10.90%), but increased the leaf thickness (18.18%) and stem diameter (over 11%) in P. lactiflora. Meanwhile, PBZ… More >

Abstract To select elite materials, the growth traits of 32 Betula platyphylla clones at three separated northern sites in Northeast China were investigated and analyzed. The results showed that there were significant differences among all variation sources in the different investigated traits (P < 0.01). Except for the carbon contents, all the coefficients of phenotypic variation of the other investigated traits were higher than 10%. The repeatability of different traits ranged from 0.760 to 0.998. Correlation analysis showed that tree height were significantly correlated with diameter at breast height, but neither was significantly correlated with leaf traits nor element contents. More >

Abstract The decomposition of soil organic carbon (SOC) plays a critical role in regulating atmospheric CO₂ concentrations and climate dynamics. However, the mechanisms and factors controlling SOC decomposition are still not fully understood. Here, we conducted a 60 days incubation experiment to test the effects of physical disturbance and nitrogen (N) addition on SOC decomposition. N addition increased the concentration of NO₃^- by 51% in the soil, but had little effect on the concentration of NH₄⁺. N addition inhibited SOC decomposition, but such an effect differed between disturbed and undisturbed soils. In disturbed and undisturbed soils, application of… More >
