“…They can expand the absorption range and area of plant roots [4] and improve plant uptake of water and nutrients in soil (e.g. N), resulting in enhanced plant resistance to drought [5] . Studies have reported that arbuscular mycorrhizal fungi can promote the nodulation in leguminous plants and N fixation by N-fixating bacteria [6] , thus improving the supply of N essential for plant growth.…”

Precision diagnosis of leaf nitrogen (N) content in arbuscular mycorrhizal inoculated crops under drought stress, using hyperspectral remote sensing technology, would be significant to evaluate the mycorrhizal effect on crop growth condition in the arid and semi-arid region. In this study, soybean plants with inoculation and non-inoculation treatments were grown under severe drought, moderate drought and normal irrigation conditions. Leaf spectral reflectance and several biochemical parameters were measured at 30 d, 45 d and 64 d after inoculation. Correlation analyses were conducted between leaf N content and the original and first derivative spectral reflectance. A series of first-order differential area indices and differential area ratio indices were proposed and explored. Results indicated that arbuscular mycorrhizal fungi improved leaf N content under drought stresses, the spectral reflectance in visible to red edge regions of inoculated plants was lower than that of non-inoculated plants. The first-order differential area index at bands of 638-648 nm achieved the best estimation and prediction accuracies in leaf N content inversion, with the determination coefficient of calibration of 0.72, root mean square error of prediction and relative error of prediction of 0.46 and 11.60%, respectively. This study provides a new insight for the evaluation of mycorrhizal effect under drought stress and opens up a new field of application for hyperspectral remote sensing.

“…Reverse transcription-PCR (RQRT-PCR) analysis showed that G. versiforme induced a defensive response against RKN, that involved the transcriptional control of VCH3 (the class III chitinase gene) expression throughout the root tissue. An AM association in monoxenic culture was successfully established between Glomus sinuosum and transformed Ri T-DNA carrot (Daucus carota L.) roots [238]. Spores, arbuscules and vesicles were produced after roots were colonized by hyphae, and the newly-produced sporocarps were capable of germination in growth medium after six months [238].…”

The significance of mycorrhizas (fungal roots in 90% of land plants) in plant nutrient acquisition and growth, element biogeochemical cycling and maintaining of terrestrial ecosystem structures has been globally established for more than 120 years. Great progress in mycorrhizal research in the past 60 years (1950-2009, 1981-2009 in particular) has also been made across China, particularly in the mainland, Hong Kong and Taiwan. For instance, a total of 20 new and approximately 120 records of arbuscular mycorrhizal (AM) fungal species, 30 new and approximately 800 records of ectomycorrhizal (EM) fungal species, a dozen of new and approximately 100 records of orchid mycorrhizal (OM) fungal species have been isolated by morphological observation and/or molecular identification in China since the 1950s. Great accomplishment has also been made in the following area, including fungal species richness and genetic structure, relationships between species composition and plant taxa, effects of mycorrhizal fungi on plant nutrient uptake and growth, resistances to pathogens and interactions with other soil microorganisms, potential of mycorrhizal fungi in phytoremediation and/or land reclamation, alterations of enzymatic activities in mycorrhizal plants, and elevated CO(2) and O(3) on root colonization and species diversity. Unfortunately, the international community cannot easily appreciate almost all Chinese mycorrhizal studies since the vast majority of them have been published in Chinese and/or in China-based journals. The aim of this review is to make a comprehensive exposure of the past and present China's major mycorrhizal research to the whole world, and then to suggest potential directions for the enhancement of future mycorrhizal research within and/or between the Chinese and international mycorrhizal community.

“…With the increase of coal production, a large quantity of solid wastes such as coal fly ash emerged in China and thus the treatment and ecological reconstruction of mine soil has attracted more and more attention of Chinese scientists. For example, Bi et al [37,38] in China University of Mining and Technology (Beijing) have been developing bioremediation technology of coal fly ash-polluted soil, fo-cusing on symbiosis effect of plant and arbuscular mycorrhizal fungus.…”

Biotechnology could be widely applied in the technological development of environmental protection. This report gives a brief Chinese review on the major progress of environmental biotechnology in the following fields: Monitoring technology and treatment of dioxin-like chemicals and cyanobacterial toxins, biofiltration for air pollution control, solid waste treatment and reutilization, bioremediation of soil pollution, risk assessment and control of endocrine disturbing substances in environment, wastewater treatment, clean production and recycling economy. The effect of government policy and fund on the progress of environmental biotechnology is also discussed.
