Effect of salt stress (NaCl) on biomass and K+/Na+ ratio in cotton

A pot experiment was conducted to evaluate performance of five Upland cotton (Gossypium hirsutum L.) varieties, Aleppo118 (A118), Aleppo33/1 (A33/1), Aleppo90 (A90), Raqqa5 (Raq5) and Deir-Ezzor22 (DE22), grown under different salinity concentration 0, 50, 100 and 200 mM NaCl for 56 days. Results indicated that increasing salinity decreased fresh and dry leaf and root weights. Also, leaf K+/Na+ ratio was decreased as increasing salinity levels in all tested varieties. This reduction for the all indicators tested was relatively more pronounced in A118 than DE22. Thereby, DE22 variety relatively performed better under salinity compared to the other tested varieties. Based on this investigation, it can be concluded that DE22 and Raq5 are relatively characterized as salt tolerant, while A90 as moderate salt tolerant. On the other hand, A118 and A33/1 could be considered as salt sensitive

TU-DAMD employment for molecular characterization of Salvia judaica and Salvia palaestina species

Genetic diversity in perennial Salvia judaica Boiss (Judean sage) and Salvia palaestina Benth (Palestinian sage) species using touch-up directed amplifi cation of minisatellite region DNA (TU-DAMD) has been performed in two separated sets; in the fi rst set (set A) the initial annealing temperature was increased from 50 °C to 55 °C, whereas, in the second one (set B), it increased from 55 °C to 60 °C by 0.5 °C/cycle during the fi rst 10 PCR amplifi cation cycles. Fifteen DAMD primers have been tested for each set. Set (A) produced 89.39% polymorphism level (P%) with polymorphic information content (PIC) average of 0.33 and marker index (MI) average of 3.96. Whereas, in set (B) these values were recorded to be 94.02%, 0.34 and 3.98 for P%, PIC and MI, respectively. Data showed that the two mentioned sets successfully highlighted high polymorphism level between the two studied Salvia sp. This work studies genetic diversity of S. judaica and S. palaestina species using TU-DAMD test as a novel molecular marker

Genetic diversity of Salvia tomentosa Miller (Lamiaceae) species using Touch-down Directed Amplification of Minisatellite DNA (Td-DAMD) molecular markers

Salvia tomentosa Miller (Lamiaceae) a Mediterranean species has an important role in various pharmacological applications. To reveal genetic relationships among S. tomentosa natural populations, 35 samples were collected from different regions of Syria. Touch-down Directed Amplification of Minisatellite DNA (Td-DAMD) markers have been investigated for this goal. Td-DAMD assay produced 158 total bands of which 131 (82.911%) were polymorphic with a mean polymorphic information content (PIC) value of 0.264 and a mean marker index (MI) value of 2.269. Clustering profile based on TdDAMD data showed that samples were grouped into two main clusters; the first cluster included Lattakia samples which split into two subclusters regardless their altitudes over the sea level. Whereas, the second cluster included Tartous and Hama samples. Td-DAMD assay successfully discriminate among the tested 35 samples belonged to the S. tomentosa natural population

GC/MS Analysis of Hypericum perforatum L. (Hypericaceae) Species

Hypericum perforatum L. aerial parts have been extracted with tetrahydrofuran solvent and their chemical composition has been investigated by Gas Chromatography-Mass Spectrometry (GC/MS) analysis. GC/MS chromatogram of the 4 tetrahydrofuran studied H. perforatum genotypes (HP) revealed that the main constituents for HP1 were: 9-Octadecenamide (Z)-(Oleic acid) (65.551%), Hexadecenamide (20.681%) and Dodecenamide (5.595%). Whereas, for HP2, they were 9-Octadecenamide (Z)- (Oleic acid) (63.117%), Hexadecenamide (19.107%) and Dodecenamide (5.585%). As for HP3, they were 9-Octadecenamide (Z)-(Oleic acid) (63.496%), Hexadecenamide (18.891%) and Dodecenamide (5.961%). Whereas, they were 9-Octadecenamide (Z)-(Oleic acid) (62.048%), Hexadecenamide (19.325%) and Dodecenamide (5.914%) for HP4. Thereby, isolation of these constituents and investigation of their biological activity is requested

Ion partitioning and Mg2+/Na+ ratio under salt stress application in cotton

The response of five cotton (Gossypium hirsutum L.) varieties Aleppo118 (A118), Aleppo33/1 (A33/1), Aleppo90 (A90), Raqqa5 (Raq5) and Deir-Ezzor22 (DE22) to salt stress (0, 50, 100 and 200 NaCl) was studied in a pot experiment, in terms of their ionic distribution for 56 days. Leaves and roots of DE22 exhibited the lowest Na+ and Cl- and the highest leaf Mg2+ contents conversely to A118. based on this investigation, there was no relationship between Ca2+ content and salt tolerance of different cotton varieties. Leaf and root Mg2+/Na+ ratios were decreased as salinity level increased for all tested varieties. In this respect, the highest value for the previous indicators was recorded in DE22 while the lowest one was recorded in A118. Thereby, among all tested varieties, DE22 variety relatively performed better under salinity compared to the other varieties

Multifunctional Nanoparticles for Imaging Guided Interventions

We describe multifunctional magnetic nanoparticles (MNPs) encapsulated in thermosensitive, drug-bearing shells and delivered to the tumor site by genetically modified and non-pathogenic strains of bacteria with known affinity to tumors for an effective and minimally invasive protocol for tumor management. The magnetic nanoparticles also serve as a non-invasive imaging contrast agent, heating agent as well as thermometry monitoring agents. We have shown an efficient tumor management on a mouse model utilizing the MNPs. Our studies showed that these novel MNPs significantly reduce the progress of tumor and prolong the animal life and function as an imaging contrast to visually monitor the tumor treatment and evolution

Transcriptomic VvPHO1 Gene Profiles Relation with Abscisic Acid (ABA) and Salicylic Acid (SA) in Grapevine (Vitis vinifera L.) under Salt Stress

Expression profile of VvPHO1 gene, abscisic acid (ABA) and salicylic acid (SA) were investigated in Baladi grapevine cultivar and B41 grapevine rootstock after different times (24, 48, 72 and 96 hours) of exposure to 2 dS/m sea water (SW). Quantitative RT-qPCR test revealed that the VvPHO1 gene, showed up-regulation from 0.27 to 2.61-fold in Baladi cv. and from 0.5 to 6.1-fold in B41 rootstock when exposure time increased from 24 to 96 h. Moreover, SW treatment caused decrease in total ABA content from 419.15 to 128 ng/g (3.274 fold) in Baladi cv. and from 1674.95 to 1559 ng/g (1.074 fold) in B41 rootstock when exposure time increased from 24 to 96 h. As for total SA, this parameter followed inverse tendency in Baladi cv. and B41 rootstock; it decreased from 126.45 to 25.6 ng/g (4.94 fold) in Baladi cv. and increased from 9.54 to 147 ng/g (15.41 fold) in B41 rootstock when exposure time increased from 24 to 96 h. Overall, data showed that VvPHO1 transcript pattern was closely related with SA level in B41 rootstock; referring that SA phytohormone could be implicated in VvPHO1 genes pathway mediates salt tolerance in grapevines

Android CompCache Based on Graphics Processing Unit

Android systems have been successfully developed to meet the demands of users. The following four methods are used in Android systems for memory management: backing swap, CompCache, traditional Linux swap, and low memory killer. These memory management methods are fully functioning. However, Android phones cannot swap memory into solid-state drives, thus slowing the processor and reducing storage lifetime. In addition, the compression and decompression processes consume additional energy and latency. Therefore, the CompCache requires an extension. An extended Android CompCache using a graphics processing unit to compress and decompress memory pages on demand and reduce the latency is introduced in this paper. This paper characterizes each data compression and decompression utility by measuring compression ratio, compression and decompression throughput, and energy efficiency to validate the process. Experimental results prove that data compression and decompression utilities can be beneficial to reduce the latency and perform faster compression and decompression compared with existing approache
