salicylic acid (sa) plays a key role in plant disease resistance and hyper-sensitive cell death but is also implicated in hardening responses to abiotic stress. the aim of this study is to examine the effects of salicylic acid on the growth, eco-physiological and biochemical characteristics in zinnia elegans plant exposed to copper stress. effects of copper (cu) on biomass, root length and shoo...

The development of type II clustered regularly interspaced short palindromic repeats (CRISPR) system has resulted in the revolution of genetic engineering and this technology has been applied in genome editing of various species. However, there is no report about the target-specific genome editing in shrimp. In this research, we developed the microinjection method for the ridgetail white prawn ...

The osmoregulatory ability and salinity tolerance of four species of decapod crustaceans (Decapoda: Natantia) were evaluated to test the degree of physiological adaptation to variations in salinity (2 d exposure to 10, 20, 25 and 32. The ecophysiological salinity tolerance of two penaeids (Metapenaeus joyneri and Penaeus semisulcatus) and two palaemonid species (Palaemon pacificus and Exopalaem...

background : 5-fluorouracil could lead to a decline in fertility in caenorhabditis elegans. the aim of this study was to describe the mechanisms underlying such an altered fertility phenotype and to illustrate the specific genes and path-ways that are involved in the related phenotypic changes in c. elegans. methods : we isolated total rna from the samples and used a new method called digital g...

We compare the genetic structuring and demographic history of two sympatric caridean shrimp species with distinct life history traits, one amphidromous species Palaemon capensis and one marine/estuarine species Palaemon peringueyi, in the historical biogeographical context of South Africa. A total of 103 specimens of P. capensis collected from 12 localities and 217 specimens of P. peringueyi co...
