Q.63

ICAR AIEEA PG Plant Biotechnology 14 July 2023 Shift-1 Paper

MCQ (Single Correct)

Universally required vitamin in tissue culture medium is:

ऊतक संवर्धन माध्यम में सार्वभौमिक रूप से आवश्यक विटामिन है:

Nicotinic acid निकोटीन अम्ल Glutamic Acid ग्लूटामिक अम्ल Thiamine HCl थायमिन हाइड्रोक्लोराइड Sucrose सुक्रोज

Vitamin requirements in plant tissue culture media (e.g., MS, White's, Gamborg B5 media):

Thiamine hydrochloride (Vitamin B1) is the only universally essential vitamin required by plant cells in vitro for carbohydrate metabolism and cellular growth (acting as the coenzyme thiamine pyrophosphate for pyruvate dehydrogenase and transketolase).
While other vitamins like nicotinic acid (niacin) and pyridoxine (B6) are beneficial supplements in MS medium, cultured plant tissues can synthesize them, making Thiamine HCl the only indispensable vitamin.

Therefore, Thiamine HCl is universally required.

पादप ऊतक संवर्धन माध्यम में विटामिन की आवश्यकता:

थायमिन हाइड्रोक्लोराइड (विटामिन B1) एकमात्र ऐसा विटामिन है जो संवर्धन माध्यम में पादप कोशिकाओं की वृद्धि और कोशिकीय श्वसन के लिए अनिवार्य रूप से आवश्यक होता है।
हालांकि निकोटिनिक अम्ल और पाइरिडोक्सिन भी माध्यम में डाले जाते हैं, लेकिन पौधे उनका स्वयं संश्लेषण कर सकते हैं, जबकि थायमिन के बिना संवर्धन संभव नहीं होता।

अतः थायमिन हाइड्रोक्लोराइड (Thiamine HCl) सार्वभौमिक रूप से आवश्यक विटामिन है।
