موضوع 8: اردو زبان کے مختلف نام
اردو زبان کو مختلف ادوار میں مختلف ناموں سے پکارا گیا۔ مختلف ادوار میں اسے ہندی،ہندوی ، ہندوستانی کے ناموں سے پکارا جاتا رہا ہے۔ڈاکٹر سلیم اختر نے اپنی کتاب "اردو ادب کی مختصر تاریخ" میں کہا ہے:
"یہ نام بعض اوقات اس مخصوص عہد کے لیے ایک بلیغ استعارہ بھی بن جاتے ہیں۔"
اردو کا لفظ:
اردو کا لفظ وسط ایشیا یا بالائی یورپ سے برصغیر میں داخل ہوا۔وہاں ریوڑ کے معنی میں استعمال کیا گیا۔سندھی زبان میں ڈھیر اور ترکی زبان میں لشکر کے معنی میں ملتا ہے۔ مغل دور میں فوج اور چھتر شاہی کے معنی میں مستعمل رہا۔اسی لیے عساکر(عسکری) کی زبان کو زبان اردو کہا جاتا تھا۔
ہندی یا ہندوی:
اردو زبان کو ہندوستان کی مناسبت سے قدیم زمانے میں ہندی یا ہندوی کہا جاتا تھا۔بقول ڈاکٹر مرزا خلیل احمد بیگ :
"شروع شروع میں یہ زبان اپنی مقامی خصوصیات کی بنا پر ہندوی ، ہندوئی یا ہندی کہلائی۔"(اردو زبان کی لسانی تشکیل)
اس نام کی شہادت قدیم ادبی تصنیفات میں بھی ملتی ہیں۔ قاضی بدر سے لے کر میں سراج الدین خان آرزوتک قدیم لغت نویسوں نے اس زبان کو ہندی یا ہندوی لکھاہے۔ اس کے علاوہ صوفیا کرام کی تحریریں اور اقوال بھی کارآمد ہوتے ہیں۔میر تقی میر نے اپنا تذکرہ "نکات الشعراء میں بھی ہندی کا لفظ استعمال کیا تھا۔ڈاکٹر سہیل بخاری نے بھی اپنی کتاب " اردو کے روپ "میں ہندی یا ہندوی کی مثال دیتے ہوئے کہا :
" شاہ عبدالطیف نے بھی قرآن مجید کا جو ترجمہ کیا اسیزبان ہندی قرار دیا۔"
زبان دہلوی:
امیر خسرو نے اردو کے لیے زبان دہلوی کا نام استعمال کیا ہے۔ اپنی مثنوی "نئے سفر" میں انھوں نے ہندوستان میں تمام مروجہ زبانوں کا تذکرہ کیا ہے۔امیر خسرو کے300 سال بعد ابوالفضل...
Allah almighty has created Human beings, the angels, and jinn for His worship alone. To guide the human beings to the right path, Allah almighty has sent many messengers to all nations and pieces of lands. Hazrat Adam (A. S.) was the first human being as well as the first Prophet of Allah on the Earth, while the Prophet Muhammad (PBUH) was the last of all in this chain. There will be no prophet after him. Now, it is the duty of every Muslims to carry and spread this universal message to the whole humanity. In this context, the message of Islam is universal. This article deals with this issue through giving proofs from the Holy Qur'an and Sunnah.
Deciphering In Vitro Regeneration Capabilities of Wheat and Investigations of Genetic Transformation in Wheat and Barley An efficient and reliable genetic transformation system is imperative for the improvement of food grains such as wheat and barley. While wheat transformation is complex due to its larger genome and high ploidy level, the barley has a limiting factor of genotypic dependency. In addition, cereals are known to be recalcitrant towards callus induction and regeneration. The biological processes behind in vitro response are complex and poorly understood. Selection of responsive genotypes and suitable media for tissue culture are important for genetic transformation. Mature embryos of wheat cultivars, lines and special stocks were used to evaluate genotypic and chromosomal response to tissue culture with variable concentrations of 2, 4-D in MS-medium. Similarly, different concentrations of IAA, BAP and Kinetin were used to find optimum combinations for regeneration. Specific expression vector pBRACT 214-NDPK2 carrying NDPK2 gene was used to compare relative Agrobacterium mediated transformation efficiency in wheat and barley. Significant differences were found among mean values of calli obtained under different concentrations of 2, 4-D for the tested wheat cultivars and lines. Callus induction frequency varied widely with genotype and exogenous auxin source ranging from 21% (Chenab 2000) to 94% (Atta Habib) at 1 and 2 mg/L of 2, 4-D, respectively. Most responsive cultivars and lines were Atta Habib, Siran, Iqbal 2000, Inqalab 2000, Marvi 2000, CIITADSW2, CIITADSW4, CIITADSW5 and CIITADSW9 which yielded maximum calli in a minimum time period of four weeks. It was found that from genome A the chromosomes 1A, 2A showed marked effect on callus induction, while from B and D genome the chromosome 3B, 7B, 2D, 4D and 6D were found responsible for the callus induction response. Based on the information from the response of substitution lines, the gene responsible for tissue culture response can be marked on to the individual chromosomes. Most efficient regeneration response was shown in Atta Habib followed by Siran and Chenab 2000 respectively. Wheat line CIITADSW5 showed significantly highest regeneration potential of 31% followed by CIITADSW1, CIITADSW4, CIITADSW5 and CIITADSW9 each with 25%. Both wheat and barley showed different responses towards callus induction and regeneration. Both embryogenic and non embryogenic calli were found in wheat with significantly greater tendency for embryogenecity in barley. The barley transformed lines showed good response on the regeneration medium as compared to wheat. PCR analysis of putative transformants using genomic DNA analyses showed a promising transformation response in barley with 27% transformation efficiency opposed to wheat where no true transgenic was obtained in any cultivar used in this study. The protocol developed and optimized for wheat and barley transformation will greatly help in crop improvement programme through genetic engineering especially in diploid relatives of cereals. Findings of this study suggested that callus induction and regeneration were genotype and hormones dependent, but independent of each other.
