Abstract EARLY FLOWERING 3 (ELF3), a light zeitnehmer (time-taker) gene, regulates circadian rhythm and photoperiodic flowering in Arabidopsis, rice, and barley. The three orthologs of ELF3 (TaELF3-1AL, TaELF3-1BL, and TaELF3-1DL) have been identified in wheat too, and one gene, TaELF3-1DL, has been associated with heading date. However, the basic characteristics of these three genes and the roles of the other two genes, TaELF3-1BL and, TaELF3-1AL, remain unknown. Therefore, the present study obtained the coding sequences of the three orthologs (TaELF3-1AL, TaELF3-1BL, and TaELF3-1DL) of ELF3 from bread wheat and characterized them and investigated the role of TaELF3-1BL in Arabidopsis.

Abstract Tomato is an important field crop, and nutritional imbalances frequently reduce its yield. Diagnosis and Recommendation Integrated System (DRIS), uses ratios for nutrient deficiency diagnosis instead of absolute concentration in plant tests. In this study, local DRIS norms for the field tomatoes were established and the nutrient(s) limiting tomatoes yield were determined. Tomato leaves were analyzed for nutrients, to identify nutritional status using the DRIS approach. One hundred tomatoes fields were selected from Chatter Plain Khyber Pakhtunkhwa and the Sheikupura Punjab Pakistan. The first fully matured leaf was sampled, rinsed, dried and ground for analyzing P, K, Ca, Mg, Cu,… More >

Abstract Sulfur is an essential macronutrient for the growth of all photosynthetic organisms and plays important roles in different metabolic pathways. However, sulfur metabolism and its related research on macroalgae with important ecological value is rather limited. In this study, marine ecological valued macroalga Gracilariopsis lemaneiformis was used to study the general physiological responses and transcriptome profiling under the sulfate deficiency. The relative growth rate of algae under sulfate deficiency was statistically significantly lower than that of control after 6 days. However, no significant differences were observed in the pigments content and Fv/Fm value, indicating that the photosynthesis was not obviously… More >

Abstract As one of the basic theories of biodiversity conservation, island biogeography has been widely accepted in the past decades. Originally, island biogeography was put forward and applied in oceanic environments. But later on, it was found out that the application was not only limited to oceanic islands, but also in terrestrial environments with relatively isolated conditions. In terms of biodiversity level, island biogeography generally focuses on a small scale, such as species diversity and genetic diversity. The studies of biodiversity on a large-scale based on island biogeography, such as ecosystem and landscape scales, were seldomly conducted. Taking Poyang Lake, the… More >

Abstract Olive (Olea europaea L.) is one of the most important and widely cultivated fruit trees, with high economic, ecological, cultural and scientific value. China began introducing and cultivating olive in the 1960s, and Yunnan Province is one of the main growing areas. Improving the cultivation and productivity of this tree crop species is an important challenge. Olive is a typical mycotrophic species and the potential of arbuscular mycorrhizal fungi (AMF) for this plant is well recognized; nevertheless, studies of olive AMF in China are still very limited. Roots and rhizosphere soils of olive were sampled from five representative growing sites… More >

Abstract Alfalfa (Medicago sativa L.), when exposed to abiotic stress such as salinity, suffers significant losses in yield and productivity. The present study evaluated the salinity tolerance of 12 alfalfa cultivars in vitro using five concentrations of sodium chloride (NaCl), ranging from 0 to 250 mmol L⁻¹ . The results obtained in the current study revealed that the Saudi cultivars, Kasimi and Hassawi, and the German cultivar (Berlin) had the highest salinity tolerance in terms of germination percentage (GP), corrected germination rate index (CGRI), days to reach 50% germination (GT₅₀), and ability to form cotyledonary and true leaves. Under mmol L⁻¹… More >

Abstract Flower bud differentiation is a key component of plant blooming biology and understanding how it works is vital for flowering regulation and plant genetic breeding, increasing the number and quality of flowering. Red soil is the most widely covered soil type in the world, and it is also the most suitable soil type for crape myrtle planting. The flower buds of crape myrtle (Lagerstroemia indica) planted in red soil were employed as experimental materials in this study, and the distinct periods of differentiation were identified using stereomicroscopy and paraffin sectioning. We optimized the steps of dehydration, transparency, embedding, sectioning and… More >

Abstract In aquaculture, high-density seaweed farming brings higher economic benefits but also increases outbreaks of diatom felt. The effective control of diatom felt in high-density seaweed farming has always been a research hotspot. This study selected two potential allelochemicals 2-hydroxycinnamic acid and quinic acid to explore their effects on a diatom Nitzschia closterium and an economic seaweed Monostroma nitidum. The results showed that 2-hydroxycinnamic acid had better inhibitory effects than quinic acid on the growth, pigment content and photosynthetic efficiency of N. closterium. Their half-maximal inhibitory concentrations at 120 h (IC_{50–120 h}) were 0.9000 and 1.278 mM, respectively. Additionally, these allelochemicals… More >

Abstract Grain filling is a crucial process that affects yield in rice (Oryza sativa L.). Auxin biosynthesis and signaling are closely related to rice yield; therefore, it is important to understand the effects of auxin biosynthesis on rice grain filling to improve crop yield. In this study, we used physiological and molecular strategies to identify the roles of auxin in rice grain filling. Exogenous application of auxin (IAA) or auxin analogues (2, 4-D) to young spikelets and flag leaves improved the seed-setting rate and yield per spike. Furthermore, real-time quantitative PCR assays confirmed that nine members of the OsYUCCA family of… More >

Abstract GRAS transcription factors play important roles in plant abiotic stress response, but their characteristics and functions in cotton have not been fully investigated. A cotton SCL4/7 subgroup gene in the GRAS family, GhSCL4, was found to be induced by NaCl treatments. Nuclear localization and transactivation activity of GhSCL4 indicate its potential role in transcriptional regulation. Transgenic Arabidopsis thaliana over-expressing GhSCL4 showed enhanced resistance to salt and osmotic stress. What’s more, the transcript levels of salt stress-induced genes (AtNHX1 and AtSOS1) and oxidation-related genes (AtAPX3 and AtCSD2) were more highly induced in the GhSCL4 over-expression lines than in wild type after… More >
