“…Bermudagrass is the most widely used warm‐season turfgrass species on golf courses in the southern US due to aggressive growth and high recuperative capacity following traffic/wear (6,24,30). Recent improvements in the cold tolerance of several new bermudagrass cultivars have extended its use further north (3,23). Although less tolerant of cold temperatures than zoysiagrass and buffalograss, bermudagrass may be successfully cultivated in the southern and central regions of the transition zone (3,30).…”

Field experiments were conducted in Texas to examine the recovery of a bermudagrass [Cynodon dactylon × C. transvaalensis (L.) Pers.] fairway from spring dead spot (SDS) disease following preemergence (PRE) herbicide applications. In 2011 and 2012 bermudagrass recovery from SDS in the non‐treated check plots (46 and 59%, respectively) was similar to bermudagrass recovery in response to oxadiazon at 3.4 kg/ha (55 and 57%, respectively) 14 weeks after treatment (WAT). Pendimethalin at 2.5 kg/ha resulted in 33 to 38% bermudagrass recovery from SDS 14 WAT. In 2011, oryzalin (1.68 kg/ha), dithiopyr (0.56 kg/ha), prodiamine (0.73 kg/ha), and dimethenamid (1.68 kg/ha) applications resulted in 21 to 25% bermudagrass recovery from SDS 14 WAT. In 2012, bermudagrass exhibited similar recovery in response to prodiamine and oryzalin (24 and 26%, respectively), while response to dithiopyr and dimethenamid was 33 and 34%, respectively, 14 WAT. Bermudagrass exhibited the least amount of recovery (13 to 14%) in response to indaziflam at 0.035 kg/ha, regardless of year. Oxadiazon can be safely used as a PRE option when bermudagrass is recovering from SDS, while the use of oryzalin, prodiamine, dithiopyr, dimethenamid, pendimethalin, and indaziflam may limit recovery and further contribute to a weakened turfgrass system.

“…Bermudagrass, Cynodon dactylon (L.) Pers., is an important perennial grass species in the botanical family Poaceae [26]. Originally native to Africa, C. dactylon has become naturalized in many places around the world and is widely distributed in tropical, subtropical, and temperate coastal areas [27].…”

Background: Geographical variation in morphological traits may reflect evolutionary patterns of morphological adaptability along environmental gradients. Comprehensive information on longitudinal patterns of morphological trait variation is very meaningful to explore morphological diversity and evolutionary trends in widespread bermudagrass. Methods: To explore the spatial patterns of morphological traits, we investigated 10 morphological traits of bermudagrass and 10 soil nutrient indexes and collected local climate data for 13 different regions from 119°E to 105°E along the latitude 34°N. Results: Considerable variations in morphological traits were observed at different longitudes, and the variations in most of the evaluated traits within populations were lower than those among populations. All of the 13 different longitudinal sites were divided into three groups based on morphological traits by cluster analysis. The major sources of diversity at the different longitudes were leaf length of the erect shoot, leaf width of the erect shoot, and the internode lengths of the erect shoot and stolon as determined by principal component analysis. Pearson correlation analysis also indicated that longitude was significantly and negatively correlated with these traits as well. Mean average rainfall was significantly correlated with leaf length of the erect shoot and the internode lengths of the erect shoot and stolon, while mean average temperature was only significantly correlated with internode length of the erect shoots. Available sulfur was significantly correlated with internode length of the erect shoot, plant height, and reproductive branch height, while the exchangeable Ca was significantly correlated with internode lengths of the erect shoot and stolon. Soil pH was significantly correlated with the internode length of the stolon. Longitude is an important factor that affects morphological trait variation in wild bermudagrass, and the leaves of the erect shoot and the internode length enlarged significantly with the collection sites moving from east to west.Conclusion: Different combinations and interactions of environmental factors (soil and climate) along a longitudinal gradient may have strong effects on one or more morphological traits of bermudagrass.

“…Although previous research identified several physiological and metabolic changes by cold stress in bermudagrass, including protein synthesis, chitinase and dehydrin expression, amino acid metabolism, etc. (Gatschet et al 1994(Gatschet et al , 1996Anderson et al 2002;Zhang et al 2006Zhang et al , 2011aZhang et al , 2011bMunshaw et al 2011), the early signal transduction of cold stress responses in bermudagrass are largely unknown.…”

As an important second messenger, calcium is involved in plant cold stress response, including chilling (<20°C) and freezing (<0°C). In this study, exogenous application of calcium chloride (CaCl 2 ) improved both chilling and freezing stress tolerances, while ethylene glycol-bis-(baminoethyl) ether-N,N,N,N-tetraacetic acid (EGTA) reversed CaCl 2 effects in bermudagrass (Cynodon dactylon (L.) Pers.). Pysiological analyses showed that CaCl 2 treatment alleviated the reactive oxygen species (ROS) burst and cell damage triggered by chilling stress, via activating antioxidant enzymes, non-enzymatic glutathione antioxidant pool, while EGTA treatment had the opposite effects. Additionally, comparative proteomic analysis identified 51 differentially expressed proteins that were enriched in redox, tricarboxylicacid cycle, glycolysis, photosynthesis, oxidative pentose phosphate pathway, and amino acid metabolisms. Consistently, 42 metabolites including amino acids, organic acids, sugars, and sugar alcohols were regulated by CaCl 2 treatment under control and cold stress conditions, further confirming the common modulation of CaCl 2 treatment in carbon metabolites and amino acid metabolism. Taken together, this study reported first evidence of the essential and protective roles of endogenous and exogenous calcium in bermudagrass response to cold stress, partially via activation of the antioxidants and modulation of several differentially expressed proteins and metabolic homeostasis in the process of cold acclimation.Keywords: Antioxidant; bermudagrass; calcium; chilling; freezing; metabolite; proteomic Citation: Shi H, Ye T, Zhong B, Liu X, Chan Z (2014) Comparative proteomic and metabolomic analyses reveal mechanisms of improved cold stress tolerance in bermudagrass (Cynodon dactylon (L.)
