Soil improvement methods can result in changes the microbial community blueberry soil. However, there have been few reports on impacts of different soil function, particularly endophytic microbe. In this study, we analyzed response composition, function and nitrogen (N) cycle to using high throughput sequencing. We aimed investigate best method from a perspective. The results showed that highest diversity was observed T4 treatment (peat combined with mushroom bran), followed by T2 acidified rice husk) both rhizosphere roots. dominant phyla were Proteobacteria Actinobacteria, which most abundance T1 sulfur) treatments soil, respectively, but opposite trend root bacterial community. Interestingly, Acidobacterium Paludibaculum, belonging Acidobacteria phylum, found influence according correlation network analysis. And these bacteria abundant communities clustered into two categories: one for treatments, another T3 (mushroom bran) treatments. Compared other had significant impact functional pathways promoted growth N fixation At module level, increased relative decreased assimilating nitrate reduction reaction (ANRA), dissimilating (DNRA), denitrification completed nitrification Additionally, microbes involved fixation. Overall, our findings suggest addition peat husk is optimal cultivation.

Cadmium (Cd) stress causes serious disruptions in plant metabolism, physio-biochemical processes, crop yield, and quality characters. Nitric oxide (NO) improves the features nutritional contents of fruit plants. However, how NO confers Cd toxicity fragrant rice plants, is sparse. Hence, present study investigated effects 50 µM donor sodium nitroprusside (SNP) on growth attributes, grain traits under (100 mg kg−1 soil). The results revealed that diminished growth, impaired photosynthetic apparatus antioxidant defense system, deteriorated traits. foliar application SNP mitigated by improving gas exchange attributes. Higher electrolyte leakage (EL) was accompanied with elevated levels malondialdehyde (MDA) hydrogen peroxide (H2O2) stress; however, exogenous reduced them. activities relative expression enzymatic antioxidants; superoxide dismutase (SOD), peroxidase (POD), catalase (CAT) ascorbate (APX) non-enzymatic antioxidants, glutathione (GSH) were stress, while regulated their activity transcript abundances. improved yield 2-acetyl-1-pyrroline content 57.68 % 75.54 respectively, which concomitant higher biomass accumulation, efficiency, pigment contents, an system. Collectively, our concluded characters Cd-affected soil.
