Hydrogen gas (H2) plays an important role in plant development and stress responses. Here, cucumber (Cucumis sativus L.) explants were used to investigate the roles of H2 adventitious root under cadmium (Cd) its physiological mechanism. The results showed that hydrogen-rich water (HRW) promoted rooting Cd 50% HRW obtained maximal biological response. Compared with treatment, + treatment significantly reduced content malondialdehyde (MDA), hydrogen peroxide (H2O2), superoxide radical (O2-),...

Introduction Desertification is a globally recognized ecological issue that poses severe threats to the environment, economic and social systems. Revegetation primary means combat desertification, yet effectiveness of revegetation practices requires reasonable quantification. Methods To identify appropriate planting patterns for in different deserts provide basis vegetation reconstruction deserts, we conducted comprehensive survey Ulan Buh Desert Kubuqi Northern China. Data on soil were...

Our previous studies suggested that both hydrogen gas (H₂) and nitric oxide (NO) could enhance the postharvest freshness of cut flowers. However, crosstalk H₂ NO during process is unknown. Here, lilies (Lilium "Manissa") were used to investigate relationship between identify differentially accumulated proteins freshness. The results revealed 1% hydrogen-rich water (HRW) 150 μM sodium nitroprusside (SNP) significantly extended vase life quality, while inhibitors suppressed positive effects...

The free radical nitric oxide (NO) is a critical regulator in modulation of wide range growth and developmental processes as well environmental responses plants. In most cases, NO interacts with plant hormones to regulate these processes. It clear that might work through either transcriptional or post-translational level. redox-based modification S-nitrosylation has been recognized NO-dependent regulatory mechanism recent years. general, can be understood product reversible reaction where...

Both nitric oxide (NO) and calcium ion (Ca2+)/calmodulin (CaM) have been shown to regulate the senescence of cut flowers. However, not much is known about crosstalk between NO Ca2+/CaM during In this study, Oriental × Trumpet hybrid lily "Manissa" were used investigate roles relationship postharvest freshness. The results show that effects CaCl2 or donor SNAP on vase life, maximum flower diameter hours until full opening dose-dependent, with an optimum concentration 20 mM 100 μM SNAP. Ca2+...

Abstract The growth and survival of woody plant species is mainly driven by evolutionary environmental factors. However, little known about the hydraulic mechanisms that respond to limitation enable desert shrub in arid habitats. To shed light on these mechanisms, 9-, 31-, 56-year-old Caragana korshinskii plants had been grown under different soil water conditions at southeast edge Tengger Desert, Ningxia, China were used this study. C. was limited rather than age non-watered habitats, which...

Desert shrubs play important roles in desertification control and vegetation restoration, which are particularly affected by droughts caused climate change. However, the hydraulic strategies associated with functional traits of desert remain unclear. Here, eight shrub species different life forms morphologies were selected for a common garden experiment at southeast edge Tengger northern China to study mediated leaf traits. Diurnal water potential change, efficiency safety, safety margin,...

Abstract Background Soil seed banks may offer great potential for maintaining and restoring desert ecosystems that have been degraded by climate change anthropogenic disturbance. However, few studies explored the year-to-year dynamics in species composition (richness abundance) of these soil banks. Thus, we conducted a 4-year study to assess effects environmental factors (meteorology microtopography) aboveground vegetation on bank Tengger Desert, China. Results We found was dominated annual...

Maintaining the water balance of soil-vegetation systems is necessary for ecological restoration desertified regions. However, major processes controlling after revegetation remains unclear. To quantify moving sand dunes, we performed an 18-year-long large-weighting lysimeter monitoring study in Tengger Desert, northern China. We measured daily precipitation, evapotranspiration (ET), and drainage loss (DL) on area revegetated with either Artemisia ordosica or Caragana korshinskii, two shrubs...

Desertification is one of the most important environmental problems in world. In arid and semi-arid regions, desert shrub reconstruction effective ways to prevent desertification promote ecological restoration. Recently, many studies have reported hydraulic trade-off, coordination, segmentation woody plants, however, mechanism how drives morphological adjustment response drought still largely unclear. Here, two-year-old seedlings Caragana korshinskii Artemisia ordosica as materials were...

Aims Water is the main limiting factor for revegetation and ecorestrotion in arid sandy areas.Soil available water content directly affects xylem transport capacity of plant.However, differences hydraulic traits leaf gas exchange different shrub species with ages under varied soil are still unclear. MethodsThe 10-year-old 30-year-old Caragana korshinskii C. liouana sand-binding area were employed to explore relationships between their photosynthetic during dry rainy season. Important...

Soil seed banks may offer great potential for restoring and maintaining desert ecosystems that have been degraded by climate change anthropogenic disturbance. However, few studies explored the annual dynamics in composition relative abundance of these soil banks. We conducted a long-term observational study to assess effects environmental factors (meteorology microtopography) aboveground vegetation on bank Tengger Desert, China. The was dominated herbs. found more rainfall growing season...
