Resistance by Enterobacter spp. towards several antimicrobial drugs and heavy metals: A review

Antimicrobial resistance developed in several pathogens poses an increasing threat to human health across the world. No country can escape from the medical and economic impacts from this serious problem. Although the antibiotic resistance is not a new phenomenon, the current magnitude and speed with which it is developing is a cause for the global concern including in India. There are so many common diseases resulting...

Colostrum immune quality of local sow breed in Benin: Growth, survival and acquisition of passive immunity in new-born piglet

The objective of this study was to evaluate husbandry practices of pregnant sows, immunoglobulin G (IgG) concentration in colostrum of sow from local breed of Benin, their transfer to litter and the survival and growth of piglets until 42 days of age within traditional farms pig. Results showed that sows were raised according to traditional practices characterized by sustainable or precarious housing without any hygiene...

Effect of growth regulators on indirect organogenesis of two grapevines (Vitis vinifera L.) cultivars

Establishment of efficient protocol for high-frequency of indirect regeneration of plantlets has a vital role in the analysis of genetic material in mass propagated plants. The optimal levels of growth regulators and light conditions were investigated on callus induction and organogenesis of cultured grapevine from in vitro tissues. Maximum calluses and shoots were produced by using medium supplemented with four...

Comparative effects of plant growth promoters and earthworms (Millsonia anomala) on rooting of cocoa orthotropic cuttings

Propagation of cocoa trees with high yield and disease resistance is envisioned for the renewal of the cocoa orchard. The dissemination of these elite varieties by orthotropic cuttings is strongly recommended to achieve quantitative and qualitative objectives. Some experiments reported that some Theobroma cacao clones produced by orthotropic cuttings do not root easily and the rate is very low, around 30 to 50% results....

Genetic diversity in quarin clover (T. quartinianum) accessions of Ethiopia using ISSR markers

Genetic diversity of Trifolium quartinianum accessions from Ethiopia were studied using Inter Simple Sequence Repeat (ISSR) markers. A total of 24 accessions, divided into three populations were used for the present study. DNA was extracted from a bulk of samples using a modified CTAB method. A total of 84 bands were amplified by the four di-nucleotid ISSR primers in the overall experimental materials. Genetic diversity...

Efficiency of sequence related amplified polymorphism (SRAP) and target region amplified polymorphism (TRAP) markers in detecting banana somaclonal variants

Screening of micropropagated banana (Musa spp.) cv. Grand Naine for somaclonal variants was carried out in the open field. The total detected variants were 26 somaclones (in addition to the normal plant) and were grouped into eight groups according to their morphological and yield characteristics. Sequence Related Amplified Polymorphism (SRAP) and Target Region Amplified Polymorphism (TRAP) techniques were used to study...

Genetic diversity of Ethiopian emmer wheat Triticum dicoccum Schrank landraces using seed storage proteins markers

Emmer wheat [Triticum dicoccum (Schrank)] cultivation in Ethiopia has been reducing and the genetic diversity maintained in the germplasm collection needs to be determined. The objective of this study was to assess the level of genetic diversity among populations of Ethiopian emmer wheat using seed storage protein analysis. Seeds of 85 accessions representing seven administrative regions of Ethiopia were obtained from...

Genetic diversity in Nepalese population of Swertia chirayita (Roxb. Ex Fleming) H. Karst based on inter-simple sequence repeats (ISSR) markers

Swertia chirayita is a highly valued but vulnerable medicinal plant species of Nepal. Its populations are declining in natural habitats due to over exploitation. Twenty-seven inter-simple sequence repeats (ISSR) primers were used to assess the genetic diversity and population genetic structure of 42 genotypes representing six natural populations of S. chirayita, from Nepal. Of the total 479 bands amplified by 27 ISSR...

Analysis of similarities within different date palm cultivars of Al-Ahsa oasis in Saudi Arabia

Date palm (Phoenix dactylifera L.) is widely cultivated in Saudi Arabia, with annual production estimated to be above one million tons. Of the 450 cultivars that are commonly used, 70 cultivars are found in the Eastern province and 20 cultivars are well known and common in the Al-Ahsa oasis. In this study, thirty seven date palm samples representing nine cultivars collected from six locations in the Al-Ahsa oasis, Saudi...
