Effect of homobrassinolide application on plant metabolism and grain yield under irrigated and moisture stress conditions of two wheat varieties. Arbuscular mycorrhizal (AM) fungi enhance plant salt tolerance. weights of leaves and roots (an average of 20% and 14%, respectively) than those without AM fungus inoculation, nificantly lower at 100-mM NaCl, but higher at 150-mM, cantly higher than that in the correspond, N and P contents by an average of 35% and 46% unde, conditions, and high salinity levels considerably increased, The Na contents in leaves and roots were significant-. Japanese Zelkova is a tough urban tree for residential shade and street plantings. Generally, 0.05 ppm either as a seed treatment or foliar spray was more effective than the 0.01 ppm treatment. Genes involved in the photosynthesis-antenna proteins pathway, isoquinoline alkaloid biosynthesis, zeatin biosynthesis and protein processing of endoplasmic reticulum pathway were enriched to the highest degree , indicating their significance and effects in response to salt stress in tomato seedlings. This study aimed to investigate the effects of AMF on G. sinensis salinity tolerance and reveal its underlying physiological mechanism.MethodsA greenhouse experiment was performed. Further, the antioxidant enzymes activity, soluble sugar and proline contents in leaf and stem were also effectively increased, and malondialdehyde (MDA) was decreased.

In the present study, we analyzed the effects of AM symbiosis and salt stress on photosynthesis, water status, concentrations of Na+ and K+, and the expression of several genes associated with photosynthesis (RppsbA, RppsbD, RprbcL, and RprbcS) and genes coding for aquaporins or membrane transport proteins involved in K+ and/or Na+ uptake, translocation, or compartmentalization homeostasis (RpSOS1, RpHKT1, RpNHX1, and RpSKOR) in black locust. Positive effects of F. mosseae on growth and the nutrient content of seedlings were higher than those of D. tortuosa, but no significant different effects on G. sinensis seedlings were observed between the two strains of F. mosseae. Salinity may limit plant growth especially in arid and semiarid regions. Notably, the effects of the AM fungus on, ), but only increased the activities of SOD, CA, ). rity of cell membranes under high salinity.

Antioxidants; Arbuscular mycorrhizal fungi; Ion balance; Nutrient uptake; Salt stress; Zelkova serrata (Thunb.) Growth, root vitality, leaf photosynthetic pigments, net photosynthetic rate, and dry weight were higher in seedlings with AM fungus inoculation. We aim to summarise these advances in this Volume, with special emphasis given to the ecological function of the mycorrhizal symbiosis. In saline conditions, AMF promoted lower decrease in photosynthesis, high shoot dry matter and low content of leaf and root Na+ and Cl-. These results suggest that AM fungus inoculation improved salinity tolerance of Z. serrata, but the physiological mechanisms differed between leaves and roots. 2014 Mar 15;171(6):421-8. doi: 10.1016/j.jplph.2013.10.023. Means topped by the same letter do not differ significantly (P < 0.05) by Tukey’s honestly significant difference test, of the roles of an arbuscular mycorrhizal fungus, Funneliformis mosseae, in alleviating salt-induced adverse effects on Z. serrata seedlings. Japanese zelkova is a deciduous shade tree or street tree that grows well in many parts of California. Tomato seedlings were exposed to different R: FR conditions (7.4, 1.2 and 0.8) under salinity stress (100 mM NaCl), and evaluated for their growth, biochemical changes, active reactive oxygen species (ROS) and ROS scavenging enzymes, pigments, rate of photosynthesis, and chlorophyll fluorescence. The left column indicates effects on leaves, the central column shows the major categories of effects, and the right column the effects on roots, Effects of NaCl levels and AM fungus inoculation treatments on the dry weight of Z. serrata seedlings. Tomato seedlings grown under the lower R: FR value and conditions of salinity showed a higher actual quantum yield of photosynthesis (ΦPSII), electron transport rate (ETR), and photochemical quenching (qP) than those exposed to a higher R: FR, indicating overall healthier growth.

Salt-stressed mycorrhizal seedlings produced greater root, stem, and leaf biomass than the uninoculated stressed seedlings. Plants with AMF under non-saline conditions presented a high photosynthesis and biomass. tive and growth-promoting effects of AMF under salt, stress have been reported on many tree species, decreased with increasing NaCl levels. KLBMP5084, Arbuscular Mycorrhizal Fungi Effectively Enhances the Growth of Gleditsia sinensis Lam. Co-inoculated maize plants also exhibited high K+/Na+ ratios in roots at 25 mM NaCl concentration. AMF effectively enhanced the salinity tolerance of G. sinensis seedlings by enhancing leaf gas exchanges inducing higher leaf net photosynthetic rates; improving peroxidase, catalase, and superoxide dismutase activities resulting in higher membrane stability indexes and lower malondialdehyde contents in leaves and roots; increasing P uptake and P/N ratio to mitigate P-limited biomass products; selectively absorbing less Na + and more Ca 2+ in their tissues to alleviate ion toxicity and maintain more favorable ion balances (e.g., K + /Na + ) in their tissues.Conclusions The tree can grow to 15 m but in practice usually reaches approx. Mycorrhizal colonization significantly positively altered the expression of ZmAKT2, ZmSOS1, and ZmSKOR genes, to maintain K+ and Na+ ion homeostasis. Salinity also impaired the non-enzymatic and enzymatic components of the antioxidant defense system. Seedlings of Z. serrata were exposed to four salt levels in a greenhouse with and without F. mosseae inoculation. Zelkova serrata – Japanese Zelkova, Keaki. Saline soil used had an electrical conductivity (EC) of 6.70 dS/m, while the garden soil had an EC of 0.29 dS/m. Spotted lanternfly is actually not a fly, but a planthopper of the family Fulgoridae, also referred to as “spot clothing wax cicada” or “Chinese blistering cicada” in the literature. Epub 2013 Jul 13. Root dry weight (b). The fruit of Ulmus are dry and winged, while Zelkova has drupes. Zelkova serrata, commonly called Japanese zelkova, is a medium to large deciduous tree, typically growing to 50-80’ tall with a spreading, generally upward-branching, vase-shaped crown.It is native to Japan, Taiwan and eastern China. Arbuscular mycorrhizal (AM) fungi enhance plant salt tolerance. Values are mean ± SE of three plants. Phonetic Spelling ULM-us par-vi-FO-li-ah Description. J Plant Physiol. | Makino were investigated in the model organism Caenorhabditis elegans. Therefore, the present study aimed to investigate the response of maize plants to co-inoculation of AMF and SAB under salinity stress. The two AMF strains mitigated salt-induced adverse effects on seedlings mainly by increasing the leaf photosynthetic ability and biomass accumulation by reducing Na+ content, increasing P, K+, and Mg2+ content, as well as by enhancing photosynthetic pigments content and the stomatal conductance of leaves. Zelkova carpinifolia 'Verschaffeltii' – Zelkova carpinifolia 'Verschaffeltii' Medium-size tree that at first sight resembles Z. carpinifolia, but is significantly smaller. Front Plant Sci. Homobrassinolide (BR) was applied either as a seed treatment or foliar spray to two contrasting wheat varieties, viz. Gleditsia sinensis Lam. These results suggest that AM fungus inoculation improved salinity tolerance of Z. serrata, but the physiological mechanisms differed between leaves and roots. Upward arrows indicate an increase and downward, Effects of F. mosseae on root colonization of Z. serrata seedling at different NaCl levels. The K content in roots showed a steeper, ). Foliage of ‘Drake’ Chinese Elm. To reveal the different mechanisms, our study utilized comprehensive analyses of leaves and roots to examine the effects of Funneliformis mosseae on the salinity tolerance of Zelkova serrata. The interaction between arbuscular mycorrhizal fungi (AMF) and AMF spore associated bacteria (SAB) were previously found to improve mycorrhizal symbiotic efficiency under saline stress, however, the information about the molecular basis of this interaction remain unknown. Named after a city within Tokyo, Japan, this narrow, upright tree is very symmetrical and a perfect candidate for formal settings. Synonyms Zelkova serrata ‘Green Vase’ Fast-growing tree that can grow to approx. However, knowledge regarding seedling cultivation (especially the use of arbuscular mycorrhizal fungi (AMF)) is scarce, which limits the developent of Gleditsia plantations. The second section deals with the eco-physiology of mycorrhizal plants. The tree is related to the elm (Ulmus) but is different in that the flowers of Zelkova are unisexual and of Ulmus are hermaphroditic. Therefore, different qualities of light can be used to efficiently develop abiotic stress tolerance in tomato cultivation. However, when compared with leaves, enhanced K contents in, AM roots might be attributed to the higher Na content, in roots than that in leaves, which requires more K to, AMF can selectively uptake elements such as K. these ratios were increased by AM fungus inoculation. The results showed that salinity reduced the net photosynthetic rate, stomatal conductance, and relative water content in both non-mycorrhizal (NM) and AM plants; the reductions of these three parameters were less in AM plants compared with NM plants. arrows a decrease relative to seedlings without mycorrhizas. These results indicate that arbuscular mycorrhization is beneficial for the growth of young G. sinensis plants. C306 (drought tolerant) and HD2329 (drought susceptible), to examine its effects on plant metabolism and grain yield under irrigated and moisture-stress/rainfed conditions. Zelkova, Japanese zelkova—Zelkova serrata. dry weight), where turgor weight was determined, ). 10 to 12 m tall. Under saline conditions, plants showed osmotic stress responses that included low leaf relative water content and high proline content. After 2 days in the normal nutrient solution, the plants showed improvements in antioxidant and glyoxalase system activities, followed by improvements in plant growth, water balance, and chlorophyll synthesis. The fruit of Ulmus are dry and winged, while Zelkova has drupes. Makino were investigated in the model organism Caenorhabditis elegans.The results revealed that the essential oil of Z. serrata heartwood exhibited great radical scavenging activities and high total phenolic content.
