  • Putrescine Enhances Seed Germination Tolerance to Heat Stress in Arabidopsis thaliana
  • 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 of HT on seed…

  • Antagonistic Potential of Bacterial Species against Fungal Plant Pathogens (FPP) and Their Role in Plant Growth Promotion (PGP): A Review
  • Abstract

    Since the 19th 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 and eco-friendly in nature.…

  • Age-Related Alterations in DNA Methylation and APETALA2 (AP2) Levels in Herbaceous Peony (Paeonia lactiflora Pall.)
  • 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. Based on…

  • Effect of Paclobutrazol Application on Plant Growth and Flower Quality in Herbaceous Peony
  • 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 application…

  • The Primacy of Moringa (Moringa oleifera Lam.) in Boosting Nutrition Status and Immunity Defence Amidst the COVID-19 Catastrophe: A Perspective
  • Abstract A severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) led novel coronavirus disease (COVID-19) outbreak spread through China has become the biggest global public health challenge today. The virus upon several mutations has led to the resurgence of more infectious and lethal variants infecting over 298 million people with more than 5.46 million deaths worldwide by the end of December, 2021. Though vaccines are available, various preventive measures particularly a high body immunity is still extremely important which determines the likelihood of disease severity and subsequent recovery in the current and future pandemics. This review acknowledges the potentiality of miraculous Moringa oleifera

  • G × E Analysis of Growth Traits of Betula platyphylla Clones at Three Separated Sites in Northeastern China
  • 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. Additive main effects…

  • Analysis of Seed Phenotypic and Metabolic Characteristics of Diploid and Tetraploid Tartary Buckwheat
  • 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 water absorption rate was higher…

  • Optimization of Callus Induction Conditions from Immature Embryos of Maize under Stress
  • 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). Interestingly,…

  • Effect of Cadmium Stress on the Growth, Physiology, Stress Markers, Antioxidants and Stomatal Behaviour of Two Genotypes of Chickpea ( Cicer arietinum L.)
  • 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 decline in…
