After ensiling for 60 days, TMR without additives were well preserved, but MTMR had...

ABSTRACT Two lactic acid bacteria (LAB) strains, Pediococcus pentosaceus SC1 and Lactobacillus paraplantarum SC2 isolated from king grass silage, were characterized their effectiveness to improve the silage fermentation quality of stylo ( Stylosanthes guianensis Sw.) was studied. Strain able grow at a high temperature 45°C, while did not. normally grew low pH 4.0, could These two strains commercial inoculant LAB L. plantarum , LP) used as additives preparation various temperatures (20°C,...

Weighted gene co-expression network analysis (WGCNA) is a research method in systematic biology. It widely used to identify modules related target traits multi-sample transcriptome data. In order further explore the molecular mechanism of maize response low-temperature stress at seedling stage, B144 (cold tolerant) and Q319 sensitive) provided by Maize Research Institute Heilongjiang Academy Agricultural Sciences were as experimental materials, both inbred lines treated with 5 °C for 0 h, 12...

Understanding changes in the distribution patterns and diversity of soil microbial communities from perspectives age-related changes, seasonal variations, interaction between two factors can facilitate management plantations. In Chinese fir plantations, we collected soils different depths over-mature forests, mature near-mature middle-aged young forests summer, autumn, winter China's subtropical regions. As developed, bacterial fungal communities' changed, reached a minimum value at then...

Background/Objectives: Abiotic stresses impose significant constraints on crop growth, development, and yield. However, the comprehensive characterization of maize (Zea mays) lipoxygenase (LOX) gene family under stress conditions remains limited. LOXs play vital roles in plant responses by mediating lipid oxidation signaling pathways. Methods: In this study, 13 ZmLOX genes were identified characterized to explore their functions abiotic stresses. Results: Phylogenetics revealed that share...

Hydroxytyrosol is a natural phenolic compound found in olives. Phenylacetaldehyde reductase (PAR) key enzyme the final step of hydroxytyrosol biosynthesis pathway However, genome-wide studies on PAR gene family olives have not been reported. In this study, 21 genes were identified through analysis. Phylogenetic analysis classified these into three subgroups: PAR, CCR (Cinnamoyl-CoA reductase), and DFR (Dihydroflavonol 4-reductase). Expression pattern suggested that within subfamilies may...

Chinese fir (Cunninghamia lanceolata (Lamb.) Hook) is one of the most important tree species for afforestation in China. First-, second-, and third-generation seed orchards have been established successively, rich germplasms accumulated process genetic improvement. It necessary to build a core collection from orchards. In this work, we constructed collections representing diversity orchard resources based on SSR data. A total 607 materials three generations were used determine best sampling...

Six wethers were used in a digestibility experiment arranged as replicated 3 x Latin square to evaluate the nutritive value of total mixed ration (TMR) silages that made from ensiling TMR containing 0, 6.5 and 13.0% (dry matter basis) spent mushroom substrate (SMS) for 45 days (treatments denoted CSMS, LSMS HSMS, respectively). The amount SMS replaced same timothy hay respective TMR. All well preserved indicated by their low pH, ammonia-N high lactic acid contents. Increasing levels silage...

Sea buckthorn is a typical drought-resistant tree species. However, there general lack of understanding the pattern DNA methylation linked with sea responses to drought, and its relationship drought tolerance mechanisms. In this study, we performed whole-transcriptome RNA sequencing methylome in response stress explore differentially expressed mRNAs, miRNAs, lncRNAs circRNAs leaves. Based on predicted DE pairs, constructed competitive endogenous network, which revealed potential...

Background The spruce forests are dominant communities in northwest China, and play a key role national carbon budgets. However, the patterns of stock distribution accumulation potential across stand ages poorly documented. Methods We investigated stocks biomass soil natural region by surveys on 39 plots. Biomass tree components were estimated using allometric equations previously established based height diameter at breast height, while understory (shrub herb) forest floor determined total...

Enhancing the aerobic stability of silage is very important in production. The objective this study was to compare roles a new bacterial strain Lactobacillus parafarraginis ZH1 with plantarum Chikuso-1 (LP) and buchneri NCIMB 40788 (LB) improving oat identify anti-yeast substances produced by them. After ensiled for 45 days, either inoculated silages or control were pH values lower than 4.2. LP had poorer LB ones (p < 0.05). more acetic acid, benzoic acid hexadecanoic one best In MRS medium,...

Abstract Background Filling silos generally takes much time in practice, which may negatively affect silage fermentation and feed intake. To clarify the effects of inoculating time, lactic acid bacteria (LAB) strains filling on microbes stylo ( Stylosanthes guianensis ) its silage, ensiling was quickly performed (quickly filling, QF) with or without LAB Lactobacillus plantarum SXC48, Lb. CCZZ1 Enterococcus faecalis XC124), after inoculated placed for 1 day (delayed DF1) 2 days (DF2). Results...

Whole-crop wheat ( Triticum aestivum , WCW) has a high nutritional value and digestibility. No-tillage (NT) can reduces energy labor inputs in the agricultural production process, thus decreasing costs. There are many studies on planting techniques of WCW at present, few being no-tillage planting. This study aimed to compare effects different tillage methods maturity stages yield, nutritive value, silage fermentation quality WCW. The experiment included two (NT; conventional tillage, CT),...
