Adaptation to low temperatures in the wild tomato species Solanum chilense

et al. 2016

Molecular adaptation to abiotic stresses in plants is a complex process based mainly on the modifications of gene transcriptional activity and the alteration of protein-protein interactions. We used a combination of population genetic, comparative transcriptomic and plant physiology approaches to investigate the mechanisms of adaptation to low temperatures in Solanum chilense populations distributed along Andean altitudinal gradients. We found that plants from all populations have high chilling tolerance, which does not correlate with temperatures in their native habitats. In contrast, tolerance to freezing shows a significant association with altitude and temperature variables. We also observed the differences in expression patterns of cold-response genes between plants from high- and low-altitude populations. These results suggest that genetic adaptations to low temperatures evolved in high-altitude populations of S. chilense. At the transcriptional level, these adaptations may include high levels of constitutive expression of the genes encoding ICE1, the key transcription factor of the cold signalling pathway, and chloroplast ω-3 fatty acid desaturase FAD7. At the sequence level, a signature of selection associated with the adaptation to high altitudes was detected at the C-terminal part of ICE1 encoding the ACT regulatory domain.

To explore the effects of kelp waste extracts (KWE) on the growth and development of Brassia chinensis L., germination and greenhouse experiments were carried out under different concentrations of KWE. The results showed that a higher germination percentage (95%), associated with high germination index (8.70), germination energy (71.67%) and seedling vigor index (734.67), was obtained under a lower KWE concentration (2%) compared with the control. The radicle length (4.97 cm), fresh weight (0.32 g/10 seedlings) and dry weight (0.015 g/10 seedlings) were significantly increased in the treatment of 2% KWE. KWE also could enhance the root growth, the maximum leaf length × width and the fresh weight of plants, the optimal value of which increased by 8.37 cm, 58.14 cm2 and 7.76 g under the treatment of 10% KWE compared with the control respectively. Meanwhile, the contents of vitamin C and soluble sugars in pakchoi leaf were improved by 19.6 mg/100 g and 1.44 mg/g compared with the control, and the nitrate content was decreased by 212.27 mg/kg. Briefly, KWE could markedly stimulate the pakchoi seeds germination at a lower concentration (2%) and enhance the plant growth and quality at a higher concentration (10%).

The present findings on Glycine betaine provides significant perception on the dynamics of pearl millet by activating the host defense responses during its interaction with the pathogen. Glycine betaine treatment to seeds at 30 mg ml -1 concentration for 6 h significantly enhanced the seed germination and seedling vigor of pearl millet in comparison with the control. Significant inhibition of sporangial sporulation, zoospore release and motility was observed at 30 mg ml -1 , even though it failed to exhibit complete inhibition in all the concentrations tested. TTC assay confirmed the declined release of sporangiospores from sporangia by inhibiting the viability of sporangiospores. Inducer treated seedlings recorded an early and increased hypersensitive response as a reaction to Sclerospora graminicola inoculation compared to untreated. The effect of Glycine betaine was tested by seed treatment alone, seed treatment + foliar application and foliar application alone. Significant inhibition of disease control was noticed in seed treatment followed by foliar application with 19.2% disease incidence at 30 mg ml -1 . Spatio-temporal studies indicated that seed treatment with Glycine betaine increased disease protection three days after inoculation. With these results, Glycine betaine has been shown to be an effective compound for the control of downy mildew disease in pearl millet.
