spartina alterniflora salt tolerance

3) (Vasquez et al. The performance of P. australis significantly decreased along the salinity gradient (Fig. The greater salt tolerance of S. alterniflora compared with P. australis was due to its ability to use Na(+) for osmotic adjustment in the shoots. Spartina alterniflora produced new biomass up to 0.6 M NaCl, whereas P. australis did not grow well above 0.2 M NaCl. However, the molecular basis of its high salt tolerance remains elusive. 2006a, Medeiros et al. Tolerance between non-resource stress and an invader determines competition intensity and importance in an invaded estuary. A repeated measures ANOVA was used to analyze the effects of salinity and plant species on the RNE, Tukey's test was used as a post hoc comparison. This type of growth response has been described as a phalanx life strategy, which allows the plant to exclude other plants from invading by increasing the size of aboveground tissues and root per unit time, resulting in high capture rate for all resources due to a high growth rate (Grime 1977, Grace 1991, Vasquez et al. However, there are no published studies to date on intraspecific variation in salt toler-ance in P. hemitomon, and the information on intra-specific variation in salt tolerance in S. alterniflora is Elevated salinity and inundation will facilitate the spread of invasive Spartina alterniflora in the Yangtze River Estuary, China. 1). The Spartina transcriptome is closer to rice than Arabidopsis, and a higher proportion of transporter and transcription factor-encoding transcripts have been found in Spartina. In mid‐April, the collected ramets were planted. In each plot, one quadrat was planted with 16 ramets of P. australis spaced at 0.3‐m intervals, the second quadrat was planted with 16 ramets of S. alterniflora spaced at 0.3‐m intervals, and the third quadrat was planted with 16 ramets of P. australis and 16 ramets of S. alterniflora spaced 0.15 m apart. Moreover, the biomass of P. australis declined with increasing salinity but that of S. alterniflora did not (Fig. experiments.

Validation fonctionnelle du rôle des miARNs dans la tolérance au phénanthrène chez Spartina: Utilisation d’Arabidopsis en système hétérologue. 4–18‰ (see Results: Remote sensing and filed survey… and Fig. and you may need to create a new Wiley Online Library account. Capital letters indicate significant differences among salinity groups; lowercase letters indicate significant differences between two years at each salinity level. 3 and 5), the field transplant experiment showed that this invader displayed good performance and a high influence (NAI) on native P. australis in high salinity zones (Fig. As some planted P. australis died, we replaced the dead ramets with additional ramets; in late May, we found that all of the replacement plants of P. australis had survived. Rapidly spreading invasive plants in salt marshes are ideal subjects for studying the effects of non‐resource stress on plant distribution. Thus, the soil salinity of the estuaries has risen. Consumer driven pollen limitation of seed production in marsh grasses. Clipboard, Search History, and several other advanced features are temporarily unavailable. From the dike to the seaward side of Dongtan marsh, we chose 4 monoculture communities of P. australis and randomly set 16 quadrats in each community. This theory suggests that the physiological tolerance and competitive ability of new arrivals are important influences on community patterns. A t‐test was used to analyze the difference of performance between the native and the invader at each salinity level. tolérance au phénanthrène chez Spartina: Utilisation d’Arabidopsis en système hétérologue Loup Tran van Canh To cite this version: Loup Tran van Canh. We collected the aboveground parts of the plants in each quadrat and measured the soil pore water salinity. Synthesis. Yi Chuan. The ramets of one plant was surrounded by those of another plant species, with the exception of the ramets in the mixture quadrat edge row. All rights reserved. Changes of plant species in an investigated plot are indicated by different hatching patterns in the left and right columns. Data shown are the mean interspecific relative neighbor effects (RNE) in the aboveground dry biomass in the treatment of salinity level in two years. Because the image is small, the polynomial method was used for all correction models, followed by the acquisition of optimal bands through PCA analysis and false‐color processing (used for artificial interpretation). alterniflora and natives” in the middle zone, and the original “mudflat–sedge–P. Ecology, 73(5):1842-1851. National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. Bedre R, Mangu VR, Srivastava S, Sanchez LE, Baisakh N. BMC Genomics. 2), the interspecific competition between two the plant species did not arise in only low salinity habitats but also occurred in high salinity habitats (Fig. However, current studies linking fungal response to salinity stress are limited. The remaining eight quadrats served as the control. Dynamics of the vegetation pattern in Dongtan marsh. P. australis failed to flower at a salinity of 20‰ and thus the inflorescence dry biomass was 0. Due to S. alterniflora invasions, the effects of soil elevation and tide became less profound. 1 and 8). Relative importance of environmental variables for the distribution of the invasive marsh species Spartina alterniflora across different spatial scales. In this study and other studies conducted in the same period, only 7 of the 650 (1.1%) planted S. alterniflora died. Seedling Germination and Salinity Tolerance in cordgrass: Spartina foliosa and Spartina alterniflora x foliosa Hybrids Courtney W. Davis Abstract An exotic cordgrass species, Spartina alterniflora, hybridized with the native cordgrass, S. foliosa, after its 1970s introduction into the San Francisco (CA) estuary. 2010, Corbin and D'Antonio 2011). Therefore, their respective reflectivity of near‐infrared and mid‐infrared lights is significantly different. Spartina alterniflora was studied through its expression in rice. It grows in a wide range of salinities, from about 5 psu to marine (32 psu), and has been described as the "single most important marsh plant species in the estuary" of Chesapeake Bay. 2006a, Liu et al. A repeated‐measures ANOVA was used to analyze the effects of salinity on the performances and NAI of the transplanted S. alterniflora, and a Tukey's test was used as the post hoc comparison. 1 and 7). 2 Citations; 246 Downloads; Part of the Tasks for Vegetation Science book series (TAVS, volume 38) Abstract. This indicated that the community stability of native P. australis could be maintained in low salinity zones and that the rate of community succession from the native to the invader was improved with the increase of salinity. Each part of the plant was oven‐dried at 80°C until a constant weight was reached to determine the total dry biomass. Would you like email updates of new search results? alterniflora” and “mudflat–S. Moreover, in the same transect, salinity did not change significantly over time (North transect: F = 0.143, p = 0.708; South transect, F = 0.012, p = 0.915; one‐way repeated‐measures ANOVA). The collected plant materials were cut into similar‐sized plantlets ca. 2012), the effects of the tolerance of new arrivals to non‐resource factors on their performance and competitiveness have been relatively ignored. Then, we measured aboveground dry biomass, density and flower ratio. australis” zonation in the southern zone (Fig. (Li et al. 2). Moreover, the new arrival influences (NAI) at salinity of 4.9‰ did not substantially change over time, but those in salinities higher than 7.8‰ declined significantly over time (Table 4; Fig. 2006). 40–80 h/15 d, 40 h/15 d and 15 h/15 d, respectively (Tang et al.  |  These examples suggest the importance of environmental conditions on interspecific competition between new arrivals and native plants. Remote sensing has been conducted eight times since 1997, and image formats were uniformly Landsat‐5TM (except in 2001 and 2002, when the image format is Landsat 7 ETM+) transformed. Published by Elsevier Masson SAS. The mudflat was then divided into a high‐salinity zone and a low‐salinity zone, with salinities of 11.83‰ ± 0.21‰ and 7.03‰ ± 0.19‰ (mean ± SE), respectively (t‐test, P < 0.05, n = 10). 2010). It is important to note that there is a high possibility of colonisation by S. alterniflora. The competitor‐stress tolerator‐ruderal theory predicts that competitors exist in highly productive habitats and that stress tolerators persist in unproductive habitats (Grime 1977, Grace 1991). The plants were harvested after six months. Specifically, some scholars have reported that the photosynthesis of cordgrass does not significantly change in the salinity range of 0–510 mM (Mateos‐Naranjo et al. Journal of Geophysical Research: Biogeosciences. Many studies have shown that P. australis and S. alterniflora have a high tolerance to the anoxia caused by inundation (Maricle and Lee 2002, Wang et al. Use the link below to share a full-text version of this article with your friends and colleagues. SaADF2 differs from OsADF2 by a few amino acid residues, including a substitution in the regulatory phosphorylation site serine-6, which accounted for its weak interaction with OsCDPK6 (calcium … Spartina plants have a salt gland and thus can excrete excess salt on the leaf face (Levering and Thomson 1971, Wang et al. 2010). 2010). Remote‐sensing data were obtained in mid‐November, when P. australis was withered and yellowed and S. alterniflora was still green; sedges, including Scirpus triqueter, Scirpus mariqueter and Carex scabrifolia, were relatively short, yellowed and fallen over. Therefore, S. alterniflora suffers relatively little damage from high salinity. 2004). 1. Therefore, the distribution area of new arrivals increases as the distribution area of natives decreases. (2005) have shown that the increase of salinity can strongly inhibit the growth of three haplotypes (viz. Both at low and high salinity, the RNEs of P. australis and S. alterniflora were significantly greater than zero (Fig. eCollection 2020. Controlled S. alterniflora should not be allowed to recover.
