باب دوم: علمی خدمات

علمی منصوبے
پروفیسر عبد الحق کا کمال یہ ہے کہ وہ کبھی بھی علم و ادب کی بساط سے خالی نہیں رہے۔ جب 12 مارچ 2004ء کو شعبہ اردو دہلی یونیورسٹی کی ملازمت سے فارغ ہوئے تو ایک ہی ماہ کے اندر یعنی یکم اپریل 2004 ء سے اقبال انسٹی ٹیوٹ کشمیر میں مہمان پروفیسر (Visiting Professor) کے طور پر فائز ہوئے۔ وہاں پر وہ چند ماہ یعنی 31 دسمبر 2004 ء تک مقرر رہے۔ اسی دوران U.G.C نے انہیں ایک تحقیقی منصوبے پر کام کرنے کی اجازت دی۔ ان کے اس تحقیقی منصوبے کا موضوع تھا” بیسویں صدی کے اردو ادب میں تفکیری تصورات“ ۔ انہوں نے اس منصوبہ پر 3 جون 2005 ء تک کام کیا۔ جواہر لال نہرو یونیورسٹی نے انہیں مہمان پروفیسر ذمہ داری سونپی۔ اس دانش گاہ میں انہوں نے پورے تعلیمی سال یعنی 12 مئی 2007ء تک کام کیا۔ یکم جون 2007 ء سے کشمیر یونیورسٹی میں دوبارہ مہان پروفیسر کے طور پر بلا لیے گئے لیکن اس بار وہ کچھ ذاتی مجبوریوں اور مصروفیات کی بنا پر کشمیر نہ جاسکے۔ پروفیسر عبد الحق کے تلامذہ اور ان کی نگرانی میں تقریباً تیس (30) طلبا و طالبات نےایم فل اور پی۔ ایچ۔ ڈی کے مقالے لکھے ہیں۔ ہندوستان میں پروفیسر عبد الحق علامہ اقبال پر سب سے پہلے پی۔ ایچ۔ ڈی کرنےوالے طالب علم ہیں (1) اس لحاظ سے علامہ اقبال ان کا اختصاص اور ان کی شناخت بن گیا لیکن علمی، تحقیقی اور ادبی سرگرمیوں میں وہ تحقیق، تنقید، مخطوطات شناسی اور دوسرے زبانی و ادبی موضوعات پر بھی مہارت رکھتے ہیں۔ اس کا اندازہ ان کی نگرانی میں تحقیق کرنے والے طلبا و طالبات کے موضوعات سے بھی لگایا جاسکتا ہے جو حسب ذیل الف پائی ترتیب سے درج کیے گئے ہیں۔

جهود العلامة إحسان إلهي ظهير في الدفاع عن العقيدة وتفنيده على الفرق المنحرفة والعقائد القاديانية كنموزج

Faith in the context of religion has a key role in the life of a person. It places a person in a belief system that evolves into a way of life and provides a unique system of logic to explain the phenomena of life around us. Good deeds are the inevitable result of sincere faith, so God constantly emphasizes rewarding those "who have faith and do good". So ʻAqīdah is the foundation of the religion Islam and it is based upon the Book of Allah and the Sunnah of Allah’s Messenger (ﷺ). Scholars of this Ummah used to give great importance to the affair of ‘ʻAqīdah by explaining it in their lessons and whenever they had an opportunity. So, they refuted the false beliefs and the deviated thoughts, and they clearly explained how they were counterfeit and baseless. A great Scholar from Pakistan named ʻAllāma Eḥsān ’Ilāhī Ẓahīr earned his fair share in spreading the correct belief. He studied at various prestigious institutions in Pakistan and abroad. He was also a graduate from the department of Sharīʻah Medina University. He studied under distinguished scholars including Shaykh Al-Albānī and Shaykh Ibn Bāz. He wrote extensively on many deviant sects such as the Qādiyānīs, Bābīs, Bahā’īs, Bātinīs and the Shīʻah. Objective of this paper to highlight the different aspects of this personality especially his great work in the field of da’wah around the world.

Expression of Chloroplast Small Heat Shock Proteins of C. Album under Different Abiotic Stresses

Plant response to the altered environmental conditions usually includes initiations of several defense mechanisms. One of these mechanisms is the heat shock proteins (HSPs) production, a universal response. Chloroplast small heat shock proteins (Cp-sHSPs) are known to protect Photosystem II under stress conditions in plants. Cp-sHSPs production is positively correlated with the plant thermotolerance. While the protective role of HSPs has been greatly recognized against several physiological stresses such as heat, metals, cold and different developmental stages individually or in different combinations. Recent progress in this field has revealed unique aspects of regulations of these genes under stress. Cis-regulatory elements present in promoter regions with the combinations of several factors dictate the gene expression levels and specific patterns. Not much is known about the regulation and mechanism of action of Cp-sHSP genes in plant protection. We analyzed four novel promoters of Chenopodium album (two US ecotypes) Cp-sHSPs for the presence of putative cis-regulatory motifs (Shakeel et al., 2011). Interestingly we found more than one cis-regulatory elements in the promoter regions of these Ca-sHSPs and based on this unique promoter architecture, we proposed a differential regulation of a single Ca-sHSP gene under variety of different abiotic stresses including heat, metal, cold, drought and salt stresses individually. To analyze the Ca-sHSP gene expression patterns under different abiotic stress conditions, we treated C. album (Pakistani ecotype) plants at different abiotic conditions and initially studied the effect of above mentioned stresses on physiology of the plants. On the basis of physiological data, we decided the lower and upper limits of stress conditions for further analyses of Ca-sHSPs. Stress induced transcripts of Ca-sHSP genes were sequenced individually and analyzed; our data showed that one novel Cp-sHSP family member, CaHSP26.13p is regulated differently under different abiotic stresses. This observation was based on 100% amino acid sequence similarities among these transcripts. Expression of Chloroplast Small Heat Shock Proteins of C. album under Different Abiotic Stresses Relative abundance of transcript and protein levels was determined by real-time PCR analysis and immunoblotting of C. album leaf samples treated with and without stress conditions. Antibodies specific to methionine rich region were used for Cp-sHSPs detection by immunoblotting. Interestingly we detected 1-2 bands of precursor and processed Cp-sHSP proteins (~26 and 21KDa) depending upon the stress conditions, while only precursor protein (~26KDa) with differential expression was detected in all types of treatments suggesting the role of single Ca-sHSP in plant protection under heat, metal, cold, drought and salt stress. Due to the absence of correlation between transcript and protein levels in most of these cases, we speculate some role of post-transcriptional regulation in plant protection by this mechanism. This study demonstrates multiple roles of single C. album Cp-sHSP in variety of environmental conditions by differential regulation and can be used to develop stress tolerant plant species to face the challenge of next decade.
