“…These two transport proteins showed higher abundance in response to cold stress. They were induced in Arabidopsis thaliana and Ananas comosus (Kinoshita et al 2011;Mirvat et al 2016). As such, A. aphylla seedlings appear to adapt to the cold environments, in part, through alterations in their amino acid metabolism and membrane transport proteins.…”

Cold stress is one of the major environmental factors that affects plant growth, development, and species distributions. In order to study the molecular mechanism of cold-stress responses in Anabasis aphylla seedlings, we used the isobaric tags for relative and absolute quantification (iTRAQ) technique to identify differential protein expression under cold stress. In total, 211 differentially expressed proteins were identified, including 109 up-accumulated proteins and 102 down-accumulated proteins, these cold-stress response proteins were mainly identified as proteins involved in carbohydrate and energy metabolism, protein metabolism and translation, stress response, transcription-related, amino acid metabolism, signal transduction, and membrane and transport. GO and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analyses indicated that most of the proteins related to cold-stress response were involved in carbohydrate and energy metabolism, indicating A. aphylla seedlings adapted to cold conditions mainly through changes in energy metabolism pathways. Additionally, the correspondence between mRNA transcript levels and protein abundance levels for nine accumulated proteins were also tested by qRT-PCR, only one protein did not show consistent trends in mRNA and protein levels. These data clarify our current understandings of stress responses in seedlings of species such as A. aphylla and identify the molecular mechanisms of the cold-stress responses.

“…The key to salt tolerance in plants is to successfully balance osmotic adjustment, ion requirements, the energy pool and the amount of Na + entering or effluxing from root cells in order to maintain a low Na + :K + ratio in the cytosol ( Redwan et al, 2016 ). To achieve this, many different processes need to be integrated to remove or compartmentalize excesss ions, to synthesize organic osmolytes to maintain osmotic balance, and to provide sufficient energy for plant growth and seed production.…”

Gene Expression Patterns in Roots of Camelina sativa With Enhanced Salinity Tolerance Arising From Inoculation of Soil With Plant Growth Promoting Bacteria Producing 1-Aminocyclopropane-1-Carboxylate Deaminase or Expression the Corresponding acdS Gene

Camelina sativa treated with plant growth-promoting bacteria (PGPB) producing 1-aminocyclopropane-1-carboxylate deaminase (acdS) or transgenic lines expressing acdS exhibit increased salinity tolerance. AcdS reduces the level of stress ethylene to below the point where it is inhibitory to plant growth. The study determined that several mechanisms appear to be responsible for the increased salinity tolerance and that the effect of acdS on gene expression patterns in C. sativa roots during salt stress is a function of how it is delivered. Growth in soil treated with the PGPB (Pseudomonas migulae 8R6) mostly affected ethylene- and abscisic acid-dependent signaling in a positive way, while expression of acdS in transgenic lines under the control of the broadly active CaMV 35S promoter or the root-specific rolD promoter affected auxin, jasmonic acid and brassinosteroid signaling and/biosynthesis. The expression of genes involved in minor carbohydrate metabolism were also up-regulated, mainly in roots of lines expressing acdS. Expression of acdS also affected the expression of genes involved in modulating the level of reactive oxygen species (ROS) to prevent cellular damage, while permitting ROS-dependent signal transduction. Though the root is not a photosynthetic tissue, acdS had a positive effect on the expression of genes involved in photosynthesis.

“…In such greenhouses, nutrient salts gradually accumulate in the soil because of fertilizer overuse and the absence of leaching with rainfall (Shi et al, 2009). This has been shown to negatively influence crop growth through an excess of nutrients and/or an osmotic effect (Fujimaki and Kikuchi, 2010;Redwan et al, 2016). In Japan, to overcome this problem in greenhouse horticulture, the field is typically flooded during a fallow period (generally in the summer) after cultivation of commercial crops to leach the accumulated salts downwards.…”

A b s t r a c t. A new methodology for comprehensive analysis of the characteristics of nitrogen (N) removal from greenhouse soil by catch crop was proposed in relation to its growth and water use. The N removal is expressed as the product of five parameters: net assimilation rate, specific leaf area, shoot dry weight, water use efficiency for N removal, and water requirement for growth. This methodology was applied to the data of a greenhouse experiment where corn was cultivated under three plant densities. We analyzed the effect of plant density and examined the effectiveness of the methodology. Higher plant densities are advantageous not only for total N removal but also for water use efficiency in N removal and growth because of the large specific leaf area, shoot dry weight, and decreased soil evaporation. On the other hand, significant positive or negative linear relationships were found between all five parameters and N removal. This should improve the understanding of the N removal mechanisms and the interactions among its components. We show the effectiveness of our analytical methodology, which can contribute to identifying the optimum plant density according to the field situations (available water amount, soil N quantity to be removed) for practical catch crop cultivation.
