Autophagy is a major and conserved pathway for delivering recycling unwanted proteins or damaged organelles to be degraded in the vacuoles. AuTophaGy-related (ATG) protein 18a has been established as one of essential components autophagy occurrence Arabidopsis thaliana. We previously cloned ATG18a homolog from Malus domestica (MdATG18a) monitored its responsiveness various abiotic stresses at transcriptional level. However, it still unclear what function under stress apple. Here, we found...
Abstract. The current understanding of the responses soil respiration (Rs) to temperature (Ts) and moisture is limited for desert ecosystems. Soil CO2 efflux from a shrub ecosystem was measured continuously with automated chambers in Ningxia, northwest China, June October 2012. diurnal Rs Ts were affected by moisture. diel variation strongly related at 10 cm depth under moderate high volumetric water content (VWC), unlike low VWC. typically lagged 3–4 h. However, lag time varied relation...
Abstract Nitrogen (N) availability is an essential factor for plant growth. Recycling and remobilization of N have strong impacts on crop yield quality under deficiency. Autophagy a critical nutrient‐recycling process that facilitates starvation. We previously showed important AuTophaGy (ATG) protein from apple, MdATG18a, has positive role in drought tolerance. In this study, we explored its biological response to low‐N. Overexpression MdATG18a both Arabidopsis apple improved tolerance...
High temperature is an abiotic stress factor that threatens plant growth and development. Autophagy in response to heat involves the selective removal of heat-induced protein complexes. Previously, we showed a crucial autophagy from apple, MdATG18a, has positive effect on drought tolerance. In present study, treated transgenic apple (Malus domestica) plants overexpressing MdATG18a with high found protected them stress. Overexpression enhanced antioxidase activity contributed production...
Abstract. The carbon (C) cycling in semiarid and arid areas remains largely unexplored, despite the wide distribution of drylands globally. Rehabilitation practices have been carried out many desertified areas, but information on C sequestration capacity recovering vegetation is still lacking. Using eddy-covariance technique, we measured net ecosystem CO2 exchange (NEE) over a shrub northwest China throughout 2012 order to (1) quantify NEE its components (2) examine dependence fluxes...
During the last decade, widely distributed shrublands in northern China have shown significant signs of recovery from desertification, result widespread conservation practices. However, to support current efforts conservation, more knowledge is needed on surface energy partitioning and its biophysical controls. Using eddy-covariance measurements made over a semi-arid shrubland northwest 2012, we examined how energy-balance components vary diurnal seasonal scales, factors control bulk...
Egg white ovomucin (OVM) is homologically related to MUC2, the key component of colonic mucous layer. This study investigated effects orally administered OVM from egg on mucosal barrier and development colitis using a C57BL/6J mice model. The results showed that daily supplementation 125 250 mg/kg BW partially relieved villous destruction loss intestinal integrity, hence decreased epithelial permeability. also reduced secretion proinflammatory cytokines TNF-α IL-6. Besides, administration...
The extent to which key factors at the global scale influence plant biomass allocation patterns remains unclear. Here, we provide a theory about how biotic and abiotic evaluate its predictions using large database for forested communities. Our analyses confirm theoretical that temperature, precipitation, height density jointly regulate quotient of leaf total biomass, they have much weaker effect on shoot (leaf plus stem) fractions scale. Moreover, larger effects than factors. Climatic...
Although the temperature response of soil respiration (Rs) has been studied extensively, several issues remain unresolved, including hysteresis in Rs–temperature relationship and differences long- vs. short-term Rs sensitivity to temperature. Progress on these will contribute reduced uncertainties carbon cycle modeling. We monitored CO2 efflux with an automated chamber system a Pinus tabulaeformis plantation near Beijing throughout 2011. Soil at 10-cm depth (Ts) exerted strong control over...
Nutrient deficiencies restrict apple (Malus sp.) tree growth and productivity in Northwest China. The process of autophagy, a conserved degradation pathway eukaryotic cells, has important roles nutrient-recycling helps improve plant performance during periods nutrient-starvation. Little is known about the functioning autophagy-related genes (ATGs) apple. In this study, one ATG8 gene family members MdATG8i was isolated from Malus domestica. putative tubulin binding sites ATG7 interaction...
Marssonina apple blotch, caused by Diplocarpon mali, is one of the most serious diseases apple. Autophagy plays a key role in pathogen resistance. We previously showed that MdATG18a has positive influence on drought tolerance. Herein, we describe how overexpression (OE) enhances resistance to D. mali infection, probably because less H2O2 but more salicylic acid (SA) accumulated leaves OE plants. Expression chitinase, β-1,3-glucanase, and SA-related marker genes was induced strongly lines....
Abstract Water deficit is one of the major limiting factors for apple ( Malus domestica ) production on Loess Plateau, a cultivation area in China. The identification genes related to regulation water use efficiency (WUE) crucial aspect crop breeding programs. As conserved degradation and recycling mechanism eukaryotes, autophagy has been reported participate various stress responses. However, relationship between WUE not explored. We have shown that protein apple, MdATG8i , plays role...
