The blueberry is an important economic fruit crop in China and has played a key role in increasing agricultural income. The county of Majiang in Guizhou is an important blueberry production region, but water shortages and low fertilizer utilization rates hamper blueberry production. Therefore, it is very urgent to take appropriate irrigation and fertilization strategies to increase the yield of blueberries. Thus, In this study, two factors of water and fertilizer, 4 irrigation levels, 3 fertilization levels and a control field experiment design were used to study the effects of different water and nitrogen treatments on blueberry plant physiology and fruit yield. The research showed that low N and moderate water treatments resulted in high fruit yields and reduced nitrate N retention in the soil. The findings provide a scientific basis and practical Guidance for using appropriate water and N management to obtain high yields of blueberries in this region. The results also provide practical and technical guidance for Minimizing environmental degradation and improving farmers’ incomes.

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 >

Abstract
Continuous cropping (CC) obstacle is a major threat in legume crops production; however, the underlying mechanisms concerning the roles allelochemicals play in CC obstacle are poorly understood. The current 2-year study was conducted to investigate the effects of different kinds and concentrations of allelochemicals, p-hydroxybenzoic acid (H), cinnamic acid (C), phthalic acid (P), and their mixtures (M) on peanut root growth and productivity in response to CC obstacle. Treatment with H, C, P, and M significantly decreased the plant height, dry weight of the leaves and stems, number of branches, and length of the lateral stem compared with control. Exogenous… More >

Abstract Tartary buckwheat (Fagopyrum tataricum) is an important pseudocereal feed crop with medicinal and nutritional value. Drought is one of the main causes of reduced growth and yield in these plants. We investigated the growth, physiological, and metabolic responses of the widely promoted Tartary buckwheat variety Chuan Qiao No. 1 to polyethylene glycol (PEG)-mediated drought stress. Drought significantly decreased shoot length, shoot biomass and relative water content. Root length, malondialdehyde content, electrolyte leakage, activities of superoxide dismutase, peroxidase, catalase and amylase, and contents of soluble sugar, soluble protein and proline were increased by PEG-mediated drought. Untargeted metabolomics analysis identified 32 core… More >

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

Abstract
To evaluate the effects of nitrogen (N) and irrigation coupling on the soil N distribution, plant N utilization, and fruit yield of rabbiteye blueberries (Vaccinium virgatum), a field experiment was designed using two factors (water and fertilizer application) with four levels of irrigation and three levels of fertilization, and a control. Under the different water and fertilizer combinations, N primarily accumulated in the leaves. Irrigation and N application within appropriate ranges (pure N ≤ 29 g/plant and irrigation volume ≤ 2.5 L/plant) significantly improved the blueberry fruit yield. Increases in water and N within these ranges promoted the effective accumulation… More >
