This approach would help track minimization effort effectiveness and would refine the characterization of DAW considerably Science. The design of the HST took into consideration its length of service and the necessity of repairs and equipment replacement by making the body modular. However, whether ALA can improve plant waterlogging tolerance is unknown. Directory of Open Access Journals Sweden Yuyan An Full Text Available 5-aminolevulinic acid ALA, a natural and environmentally friendly plant growth regulator, can improve plant tolerance to various environmental stresses. The HST program began as an astronomical dream in the s.
The new enzyme was created by the replacement of the Ser residue with acidic amino acids, as it was speculated to bind to the second D-Ala of D-Ala-D-Ala.
In addition, a replacement of the position with Glu performed better than that with Asp with Hourney spin-infarkt to specificity for D-AlaNH 2 production. The SE variant could catalyze the synthesis of 9.
This is the first report showing the enzymatic formation of amino acid amides from amino acids. Directory Hourney spin-infarkt Open Access Journals Sweden Yuyan An Full Text Available 5-aminolevulinic acid ALA, a natural and environmentally friendly plant growth regulator, can improve plant tolerance to various environmental stresses.
However, whether ALA can improve plant waterlogging tolerance is unknown. Here, we investigated the effects of ALA pretreatment on the waterlogging-induced damage of fig Ficus carica Linn.
ALA pretreatment significantly alleviated stress-induced morphological damage, increased leaf relative water content RWC, and reduced leaf superoxide anion [Formula: see text] production rate and malonaldehyde MDA content in fig leaves, indicating ALA mitigates waterlogging stress of fig plants. We further demonstrated that ALA pretreatment largely promoted leaf chlorophyll content, photosynthetic electron transfer ability, and photosynthetic performance index, indicating ALA significantly improves plant photosynthetic efficiency under waterlogging stress.
Moreover, ALA pretreatment significantly increased activities of leaf superoxide dismutase SOD and peroxidase POD, root vigor, and activities of root alcohol dehydrogenase ADH, and lactate dehydrogenase LDH, indicating ALA also significantly improves antioxidant ability and root function of fig plants under waterlogging stress.
Taken together, ALA pretreatment improves waterlogging tolerance of fig plants significantly, and the promoted root respiration, leaf photosynthesis, and antioxidant ability may contribute greatly to this improvement.
Our data firstly shows that ALA can improve plant waterlogging tolerance.
