Plants are unable to remove and predict different environmental stresses so they acquire number of mechanism to adjust these changes. Plants receive stimulations from external environment and pass these to the defense response genes, which show their responses, there are number of environmental stresses, which categorized into biotic and abiotic stresses. There are number of transcriptional factors, which control these stresses. Draught, salinity, water and UV radiations are some major stresses, which are reducing the productivity of plants in the world. The most important transcriptional factors are WRKY transcription factor in plants. These factors control number of development events and stresses responses in plants. These WRKY proteins consist of highly specific domain and they interact with other proteins due to these domains. WRKY domain act very important role against the environmental stresses and in the development of plants. WRKY protein has quick, short-lived and related to particular tissue expression under different environmental stresses. WRKY transcriptional factors carry out different function in plants like growth, development metabolism and transduction. WRKY are largest transcription factors which are highly plant-specific transcription factor and they are named due to highly preserved amino acid WRKYGQK in the N-terminus. The number of sequenced genome has been increased at very large amount which assist the evolution of WRKY protein family. Many species of plants have different numbers of WRKY genes which baised on their zinc finger motif. There are 97 WRKYs in Oryza nivara, 102 WRKYs in Oryza sativa, 171 WRKYs in Triticum aestivum, 116 WRKYs inZea mays species etc. Mosses contains 30-40 WRKY genes which were previously consisder as not plants species. Comparative genomic studies with bio-computational techniques show that these genes are present mostly in plant species. The evaluation and due to verities of plants species show that these transcription factors related to specific regulator families. Due to presence of SNPs in DNA sequence of different plants they show different mechanism for different transcriptional factors. In our present study we particularly focused on abiotic stresses and identified the SNPs which are present in plants due to which their stress mechanism changes. Our study reveals that SNPs are very important tools to show genetic relationship between different plants species.

مولوی عبدالحمید ندوی

مولوی عبدالحمید ندوی
یہ سطور ابھی پریس نہیں گئی تھیں کہ مولوی عبدالحمید ندوی کے انتقال کی خبر ملی، وہ بارہ بنکی کے ایک گاؤں جیسکھ پور کے رہنے والے تھے، بڑے مخلص، حق پسند اور بہی خواہ خلق تھے، ۱۹۱۹؁ء میں ندوہ میں داخل ہوئے، تحریک خلافت شباب پر تھی، حمید صاحب بھی اس سے متاثر ہوئے، اس کی وجہ سے سادگی طبیعت ثانیہ بن گئی، مولانا عبدالرحمن نگرامی کی صحبت نے ان کے اندر ندوہ کی محبت اور خاموش خدمت کا جذبہ پیدا کیا، تعلیم سے فراغت کے بعد قیام زیادہ تر وطن ہی میں رہا، لیکن ندوہ برابر آتے جاتے رہتے تھے، دوستوں کے اصرار کئی برس تک بھٹکل میں تعلیمی خدمت انجام دی، ان کے مخلص شاگردوں نے اس کام کو آگے بڑھایا اور ایک بڑا تعلیمی مرکز قائم ہوگیا، عرصہ سے دل کے مریض تھے، رمضان میں ندوہ آئے، مولانا ابوالحسن علی سے ملنے رائے بریلی جانے کا ارادہ تھا، دفعتہ دل کا دورہ پڑا اور تھوڑی دیر میں جان جان آفریں کے سپرد کردی، اﷲ تعالیٰ ان کی مغفرت فرمائے اور ان کے صاحبزادہ مولوی عبدالرشید ندوی اور دوسرے متعلقین کو صبر جمیل عطا فرمائے۔ (عبد السلام قدوائی، ستمبر ۱۹۷۸ء)

 

عالمی امن میں اسلام کا کردار

We live in a global village. The cyber world has brought together people and shurnk the distences, yet multi cultural, multi ethinic and multi national has become the norm of the day. There is virtually no such place, no town, no village, city or state where people from diverse backgrounds speaking diffirent lagnuages and professing diffirent creeds live. This diveristy and variety is the essence of life.  This paper analyzes various ways of establishing peace in the light of Islamic teachings. It finds out the causes of quarrels and disputes in different nations so that they may be prevented to make the world peaceful.

Spectrum Sharing in Cognitive Radio Based on Smart Antenna

In this thesis, spectrum sharing in cognitive radio based on smart antenna is considered. The thesis is divided into two parts. In first part, the convex optimization has been used for parallel spectrum sharing in cognitive radio environment with smart antenna. Three different algorithms are proposed in this domain. First algorithm maximizes cognitive user SINR subject to the constraint that interference level must kept below a predefined limit for primary user. This improves the quality of service of cognitive user at the same time by preventing the primary user from the interference. Second algorithm deals with the situation when primary and cognitive users are in the same direction. In this case cognitive user gain is optimized subject to the separation angle. This will minimize cognitive gain and the spectrum will be utilized by primary user. Third algorithm optimizes the power of cognitive user, based on the separation angle between cognitive user and primary users. This optimized power of cognitive user will have minimum interference affect on primary user. In second part of thesis, spectrum sharing in cognitive radio is achieved through side-lobe suppression by using the generalized side-lobe cancellation (GSC). For this purpose, multiple GSCs are used in parallel to suppress side-lobes. This result in reduced side-lobe level at the primary receiver, thus the interference of cognitive user towards primary user will be kept in limits. Similarly in case of reduction of side-lobes levels of cognitive receiver, the interference of primary towards cognitive user will be reduced. Hence, this thesis is supportive and effective to embed the smart antenna in cognitive radio. The simulation results have been generated in diversified environments to verify the validity of the proposed algorithms. Results have been compared with the existing classical techniques.
