“…Proteomic [255] and transcriptome analysis [116,188,256,257] have shown that the activity of cytosolic glycerol 3-phosphate dehydrogenase (GPDH) is positively correlated with TAG accumulation in algae. Moreover, overexpression of GPDH in P. tricornutum [258] and C. reinhardtii [259] increased lipid production. A multiple gene engineering strategy, including overexpression of glycerol kinase, GPDH and acetyl-CoA carboxylase, in Scenedesmus quadriauela increased the G3P pool and was paralleled by an increase in oil content [260].…”

“…In order to understand the allelopathic effect of combined materials and to receive a more reactive natural herbicide, binary mixtures of seven natural molecules (containing a variety of functional groups), namely R -(+)-limonene ( A ) [ 23 , 24 , 25 ], vanillin ( B ) [ 26 , 27 , 28 , 29 , 30 ], xanthoxyline ( C ) [ 11 ], vanillinic acid ( D ) [ 28 , 31 , 32 , 33 , 34 , 35 ], linoleic acid ( E ) [ 36 , 37 , 38 , 39 ], methyl linoleate ( F ) [ 40 , 41 , 42 , 43 ], and (±)-odorine ( G ) [ 12 , 13 ] ( Figure 1 ), were investigated using Chinese amaranth ( Amaranthus tricolor L.) as the test plant and Tween ® 80 as a surfactant. Chinese amaranth was chosen as a representative dicot plant because it has a high percentage of germination.…”

Seven allelochemicals, namely R-(+)-limonene (A), vanillin (B), xanthoxyline (C), vanillic acid (D), linoleic acid (E), methyl linoleate (F), and (±)-odorine (G), were investigated for their herbicidal activities on Chinese amaranth (Amaranthus tricolor L.). At 400 μM, xanthoxyline (C) showed the greatest inhibitory activity on seed germination and seedling growth of the tested plant. Both vanillic acid (D) and (±)-odorine (G) inhibited shoot growth, however, apart from xanthoxyline (C), only vanillic acid (D) could inhibit root growth. Interestingly, R-(+)-limonene (A) lightly promoted root length. Other substances had no allelopathic effect on seed germination and seedling growth of the tested plant. To better understand and optimize the inhibitory effects of these natural herbicides, 21 samples of binary mixtures of these seven compounds were tested at 400 μM using 0.25% (v/v) Tween® 80 as a control treatment. The results showed that binary mixtures of R-(+)-limonene:xanthoxyline (A:C), vanillin:xanthoxyline (B:C), and xanthoxyline:linoleic acid (C:E) exhibited strong allelopathic activities on germination and seedling growth of the tested plant, and the level of inhibition was close to the effect of xanthoxyline (C) at 400 µM and was better than the effect of xanthoxyline (C) at 200 µM. The inhibition was hypothesized to be from a synergistic interaction of each pair of alleochemicals. Mole ratios of each pair of allelochemicals ((A:C), (B:C), and (C:E)) were then evaluated, and the best ratios of the binary mixtures A:C, B:C and C:E were found to be 2:8, 2:8, and 4:6 respectively. These binary mixtures significantly inhibited germination and shoot and root growth of Chinese amaranth at low concentrations. The results reported here highlight a synergistic behavior of some allelochemicals which could be applied in the development of potential herbicides.

“…Thin layer chromatographic technique was adopted to separate the lipids extracted from different nutrient conditions, using the developing solvent (hexane; diethyl ether; acetic acid in the ratio of 70:30:1) (Herrera-Valencia et al, 2012). Triolein (HIMEDIA, Mumbai, India) was used as TAG standard.…”
