Characterization and molecular mapping of drought tolerance in kabuli chickpea (Cicer arietinum L.)
Abstract
Drought is the most common abiotic stress limiting chickpea production in the world. Ninety percent of the world’s chickpea is produced in areas relying upon conserved, receding soil moisture, therefore, crop productivity is largely dependent on efficient utilization of available soil moisture. Because of the variability in drought pattern from year to year, trait based selection could have an advantage over selection on the basis of grain yield alone. Trait based breeding, however, requires trait dissection into components. Successful marker identification would facilitate integration of MAS procedures in breeding programs enabling the pyramiding of favourable alleles.
The genetic map produced in this study was based on a population of recombinant inbred lines of a cross of ILC 588 x ILC 3279 containing 52 SSR markers spanned 335 cM of the chickpea genome at an average density of 6.4 cM. A total of 13 genomic regions were shown to be associated with drought tolerance traits. Some of these genomic regions showed pleiotropic effect on multiple traits. This was also supported by the analysis of phenotypic data where these traits were found to be correlated. For example, early flowering and maturity had a strong association with high grain yield. High grain yield was also associated with better portioning ability between biomass and grain yield, i.e. harvest index. Drought tolerance score (DTS) was associated with various important traits including biomass, early flowering, early maturity.
This study also concluded that chickpea genotypes differed in terms of root length, root length density, root weight density and root length to weight ratio at every 20 cm soil layer up to 100 cm depth in response to water deficits. Consideration of an efficient root system vs. a larger root system is also important, since in this research, large root systems were offset by low harvest index, presumably due to the lack of assimilate available for grain growth. A restricted root system is important in environments like Western Canada, where crop growth termination is usually required prior to fall frost. This study also reported significant associations of stomatal conductance (gs) with each of HI, grain yield under drought, drought susceptibility index and drought tolerance score (DTS). Stomatal conductance can also be used to assess plant stress due to drought. Values of gs less than 250 mmol m-2s-1 during flowering indicated drought stress under greenhouse conditions. A higher degree of plant stress due to drought was shown by increased stomatal closure at midday (g

N-{4-[(3-Methylphenyl)sulfamoyl]phenyl}benzamide
In the title compound, C20H18N2O3S, the dihedral angle between the central benzene ring and the amide group is 24.1 (3)° and that between this ring and the aromatic ring of the tolyl group is 68.2 (16)°. In the crystal, adjacent molecules are linked by N—H⋯O hydrogen bonds into a linear chain running along [100]. Weak C—H⋯O contacts also occur. Extensive weak π–π interactions exist from both face-to-face and face-to-edge interactions occur between the aromatic rings [centroid–centroid distances = 3.612 (2) and 4.843 (2) Å]
IS JHRM Style Can Be Effectively Implemented In Developing Nations of ASIA (The Case of five Pakistan, Bangladesh, Afghanistan, Nepal, Vietnam,)
In this research work Impact of JHRM Japanese Human recourse Management practices were trying to implement on different countries among developing nation in Asian continent. The countries for this research study were Pakistan, Afghanistan .Nepal, Vietnam, and Bangladesh. The reason for selecting these countries among Asian continent is because of their response rate, information in hand from different sources, and most importantly their ranking among developing nation as well as their importance to international community. As all of the above mention countries facing serious threat on its national as well as international front in order to solve these problem we are trying to evaluate the importance of HR from Japanese prospective as the same circumstances were there before WWII but when there concentrate on their HR Japanese become the leading country for other nations. For this purpose we select 20 firms from each countries and data was collected through published material as well as their HDI and HR departments. In order to get more comprehensive data .A well designed questioners was sent to respective department via email. The main concept was derived from (JSM) and it is implemented to all the above mention countries.Chai square test was used for testing the hypothesis. The result shows different attributes after analyzing the data in all of the above mention countries. As in case of Afghanistan, Pakistan and Bangladesh the major problems in order to implement these JHRM practices was bureaucratic nature of government, centralized government, top to down decision making style, and institutiolized corruption are the major problem in way of implanting JHRM style. While in case of Vietnam, Bangladesh when JHRM important feature regarding Quality was investigated the results shows that although there is great desire to implement it but the main problem is lack of knowledge and no training & development concept in this regard. Hence from the current research we can conclude that although there is a chance to implement JHRM style in these developing countries but first of all we should removed all the barriers in its effectiveness. Key words; JHRM, Developing nations, Quality, Human Recourse, Asian countries
Impact of Capital Asset Pricing Model (CAPM) on Pakistan (The Case of KSE 100 Index)
In this paper the estimated return on stock model i.e. Capital Asset Pricing Model (CAPM) is employed in order to get information whether it better estimates the return on stock in Pakistani capital market. For this purpose time series monthly data from secondary sources for a period of 2003 to 2007 has been taken. CAPM were tested for the five sizes and book to market portfolios from Karachi Stock Exchange. Pakistan T-bill rate is taken as risk free rate. However basic problem with (CAPM) was predictive power and Robustness of results. For this purpose capital asset pricing model was applied. Dependent variable portfolio represented by . The excessive return shows the return above that of the risk free rate that is required by the investor for taking additional risk. While independent variables were market risk premium. Research Findings show that CAPM better estimates the return in Pakistani capital market. In case of CAPM, it was able to show the existence of risk premium as the only factor affecting the stock return. Key Words: CAPM, Market portfolio, KSE, Risk Premiumii
Pakistan-India Relations: Peace through Bilateral Trade
The idea behind this study is to identify the importance of trade in Pak-India peace process. This study emphases that trade is instrumental in achieving and maintaining peace and stability in the Indian subcontinent. Economic interdependence promotes peace and mutual economic benefits preclude war between nations and this concept has been argued in the paper. Furthermore, considering Pakistan-India trade relations; barriers to bilateral trade; current trade volume; measures needed to be adopted for improving bilateral trade and its role in Indo-Pak peace negotiations, territorial and border disputes and peace settlement have been analyzed. It is, therefore, concluded that trade can play a soft and positive role in conflict resolution between the two long standing adversaries. Key Words: Trade Relations, Peace Process, Economic Factors, Most Favored Nation Status, Bilateral Ties
Surgical interventions for renal cell carcinoma with thrombus extending into the inferior vena cava: A multidisciplinary approach
Objective: To assess surgical strategies and the impact of a multidisciplinary approach on patients undergoing inferior vena caval thrombectomy for renal cell carcinoma and to evaluate perioperative morbidity and mortality associated with these procedures. Methodology: A retrospective audit for all adults who underwent nephrectomy and inferior vena caval thrombectomy from January 2008 till November 2018 at a University hospital. Patients with incomplete records were excluded from the study. Results: During the study period, 21 patients underwent inferior vena caval thrombectomy as a completion of radical nephrectomy. Most were males (19 : 2) with a mean age of 54±11.3 years. The most common surgical approach was the 11th rib flank approach (n=8) followed by midline abdominal (n=6) and Mercedes-Benz (n=5). Eight patients had level 1, 10 patients had level 2, and three patients had level 3 tumour thrombus. The cavotomy was closed primarily in 20 patients; one required inferior vena cava (IVC) reconstruction with a pericardial patch. The proximal clamp was applied below the hepatic veins for most patients. Two patients required suprahepatic clamping before thrombectomy. There was no intraoperative mortality. Five patients (24%) developed complications: two required cardiopulmonary resuscitation due to severe hypotension and were revived; one developed acute renal failure; and one patient required a damage control laparotomy for excessive oozing. There was no thirty-day mortality. Conclusion: The IVC thrombectomy, along with radical nephrectomy for renal cell carcinoma for 1-3 level thrombus, can be performed with acceptable morbidity in a multidisciplinary team approach
DOES CORPORATE GOVERNANCE MATTER FOR ASSET QUALITY OF ISLAMIC BANKS?
This study investigates the impact of corporate governance on asset quality of Islamic banks by employing data on 129 Islamic banks from 29 countries spanning the period from 2008 to 2017. The study shows that asset quality of Islamic banks is positively and significantly sensitive to an increase in board independence, Shariah board, and audit committee effectiveness. The study finds that female participation in management as CEOs seems to detract from good performance and that more board meetings can be harnessed to improve banks’ asset quality. These empirical findings have practical policy implications regarding asset quality management and board construction within the Islamic banking sector.This study investigates the impact of corporate governance on asset quality of Islamic banks by employing data on 129 Islamic banks from 29 countries spanning the period from 2008 to 2017.
