“…We found that the rate of growth and metabolic for females was higher than males, so the root structure of females had an advantage over males. As shown above, AMF colonization significantly enhanced the RL, RSA, and RV when exposed to salt stress, which was consistent with Tian et al (2013). With the help of AM fungi, males could have a better root system, which is a key factor to help plants uptake water from soil.…”

The influence of arbuscular mycorrhizal fungi (AMF) Rhizophagus irregularis on biomass, root morphological characteristics, water status, gas exchange and ion contents of Populus cathayana Rehder males and females under salt stress was studied in a greenhouse experiment. Sex had no influence on AMF colonization. Salt stress decreased the biomass, modified root characteristics, inhibited photosynthesis, relative water content (RWC), while increased the water use efficiency (WUEi), the ratio of root/shoot (RSR) and salt ion contents within the plants. Males and females differed in response to the salt stress and AMF inoculation. AMF inoculation increased the biomass of root, the biomass of shoot, and decreased RSR, especially in males. The root length, root volume (RV), root surface area, and root tip numbers (RTN) were increased with AMF inoculation in males, while RV and RTN were decreased with AMF inoculation in females. AMF had positive effects on RWC and WUEi in both sexes. Mycorrhizal cuttings also had higher gas exchange capacity, lower salt ion contents than non-mycorrhizal cuttings. The principal component analysis showed that males exhibited a better salt tolerance than females, and AMF inoculation had positive effects on both sexes, especially in males.

“…Tian et al (2013) reported that inoculation with AMF significantly increased leaf CAT activity in Plukenetia volubilis seedlings, thus, alleviating oxidative damage by drought stress. Our results showed that although the Mg deficiency significantly restricted leaf and root CAT activity in AM and non-AM seedlings, CAT activity in mycorrhizal seedlings was 82 and 15% higher in leaf and root, respectively, under the Mg-D conditions, and 17 and 19% higher in leaf and root under the Mg-S conditions (Fig.…”

“…Studies have proved that the SOD activity of lettuce inoculated with Glomus mosseae was significantly higher than the un-inoculated plants under drought (Ruiz-Lozano et al, 1996). Tian et al (2013) showed that the Plukenetia volubilis plants colonized by G. versiforme increased guaiacol peroxidase (G-POD) and CAT activities, thus reducing the damage caused by ROS accumulation under drought. The Allium sativum plants colonized by G. fasciculatum had markedly higher leaf SOD and CAT and root POD activities under SWD, compared with the non-AMF colonized controls (Borde et al, 2012).…”

Arbuscular mycorrhizal fungi (AMF) can enhance tolerance of plants to soil water deficit, whereas morphological observations of reactive oxygen species and antioxidant enzyme system are poorly studied. The present study thereby evaluated temporal variations of the antioxidant enzyme system in citrus (Citrus tangerina) seedlings colonized by Glomus etunicatum and G. mosseae over a 12-day period of soil drying. Root colonization by G. etunicatum and G. mosseae decreased with soil drying days from 32.0 to 1.0% and 50.1 to 4.5% in 0-day to 12-day, respectively. Compared to the non-AM controls, the AMF colonized plants had significantly lower tissue (both leaves and roots) hydrogen peroxide (H 2 O 2 ) and superoxide anion radical (O 2•-) concentrations during soil water deficit, whereas 1.03-1.92, 1.25-1.84 and 1.18-1.69 times higher enzyme activity in superoxide dismutase, peroxidase (POD) and catalase. In situ leaf H 2 O 2 and root POD location also showed that AM seedlings had less leaf H 2 O 2 but higher root POD accumulation. Furthermore, significantly higher root infection and antioxidant enzymatic activities in plants colonized with G. mosseae expressed than with G. etunicatum during the soil drying. These results demonstrated that the AMs could confer greater tolerance of citrus seedlings to soil water deficit through an enhancement in their antioxidant enzyme defence system whilst an decrease level in H 2 O 2 and O 2•-.
