“…As discussed above, this study clearly demonstrated that LT significantly decreased Pn and Fv/Fm (Fig 1B and 1C), which agrees with a previous study [25]. Moreover, this study showed that these decreases could be perfectly explained by both the significantly enriched GO terms and KEGG terms as indicated by transcriptome analysis.…”

“…Chlorophyll fluorescence analysis is one of the most powerful and popular techniques for the investigation of the influence of various stresses on the leaf gas exchange [23]. Several studies reported that LT significantly reduced net photosynthesis rate (Pn) and the ratio of variable to maximal fluorescence (Fv/Fm) [24][25][26][27] in plants; it also increased the activity of antioxidant enzymes such as superoxide dismutase (SOD, EC 1.15.1.1) and catalase (CAT, EC 1.11.1.6) [28] to resist possible injury. However, if the production rate of reactive oxygen species exceeds the scavenging ability of antioxidants, reactive oxygen species would excessively accumulate and damage plant tissues [29][30].…”

Low temperature induces changes in plants at physiological and molecular levels, thus affecting growth and development. The Lanzhou lily (Lilium davidii, var. unicolor) is an important medicinal plant with high economic value. However, the molecular mechanisms underlying its photosynthetic and antioxidation responses to low temperature still remain poorly understood. This study subjected the Lanzhou lily to the two temperatures of 20˚C (control) and 4˚C (low temperature) for 24 h. Physiological parameters related to membrane integrity, photosynthesis, antioxidant system, and differentially expressed genes were investigated. Compared with control, low temperature increased the relative electrical conductivity by 43.2%, while it decreased net photosynthesis rate, ratio of variable to maximal fluorescence, and catalase activity by 47.3%, 10.1%, and 11.1%, respectively. In addition, low temperature significantly increased the content of soluble protein, soluble sugar, and proline, as well as the activity of superoxide dismutase and peroxidase. Comparative transcriptome profiling showed that a total of 238,109 differentially expressed genes were detected. Among these, 3,566 were significantly upregulated while 2,982 were significantly downregulated in response to low temperature. Gene Ontology enrichment analysis indicated that in response to low temperature, the mostly significantly enriched differentially expressed genes were mainly involved in phosphorylation, membrane and protein kinase activity, as well as photosynthesis, light harvesting, light reaction, and alpha,alpha-trehalose-phosphate synthase activity. Kyoto Encyclopedia of Genes and Genomes enrichment analysis also indicated that the most significantly enriched pathways involved ribosome biogenesis in eukaryotes, phenylalanine metabolism, circadian rhythm, porphyrin and chlorophyll metabolism, photosynthesis of antenna proteins, photosynthesis, and carbon fixation in photosynthetic organisms. Moreover, the expression patterns of 10 randomly selected differentially expressed genes confirmed the RNA-Seq results. These results expand the understanding of the physiological and molecular mechanisms underlying the response of the Lanzhou lily to low temperature stress.

“…Our results revealed that Chl a, Chl b and total Chl contents were severely affected in maize by individual and concurrent drought and chilling stresses (Figure 7), nonetheless, the Chl a and total Chl contents were increased in XD889 under chilling stress (Figure 7a and 7c [37]. Drought and chilling stress could lead to excessive ROS production which deteriorate chlorophyll contents in plant [38,39].…”

Maize belongs to tropical environment and is extremely sensitive to drought and chilling stress, particularly at early developmental stages. The present study investigated the individual and combine effects of drought (15% PEG-Solution) and chilling stress (15C/12C) on the morpho-physiological growth, osmolyte accumulation, production and regulations of reactive oxygen species (ROS) and the activities of antioxidants in two maize hybrids i.e. XD889 and XD319 and two inbred cultivars i.e. Yu13 and Yu37. Individual and combined drought and chilling stresses stimulated the production of O 2 , H 2 O 2 , OH and enhanced malondialdehyde (MDA) contents which led to reduced photosynthetic pigments and morphological growth.Drought, chilling and drought + chilling stress conditions induced the compatible osmolytes, ROS detoxifying proteins and antioxidants to counterbalanced the oxidative damage. It was found that the concurrent occurrence of drought + chilling stress was more lethal for maize seedling growth than the drought and chilling individual stresses. However, the performance of hybrid maize cultivars (XD889 and XD319) was better than the inbred maize cultivars (Yu13 and Yu37). For improving tolerance to individual and concurrent drought and chilling stress in maize, future research focus should be on developing genetically engineer plants that have the ability to generate specific response against sub-optimal temperature and water deficit conditions.
