An enormous range of plant substances are covered by the term ‘Terpenoids’ which is used to indicate that all such substances have a common origin. This Terpenoids are a diverse group of naturally occurring organic compounds mostly found in plants. They are any of a class of hydrocarbons that consist …

ঢাকা বিশ্ববিদ্যালয়ের উদ্ভিদবিজ্ঞানের ছাত্রছাত্রীদের গাছের নাম জানা শুরু হয় কার্জনের গাছ দেখেই। কত হরেক রকম গাছ আছে আমাদের এই কার্জনে, আর উদ্ভিদবিজ্ঞানের বাগানে ঢুকলে তো কথাই নেই। তবুও বাস্তবতা হচ্ছে চোখের সামনের অধ্যয়নের বিষয় থাকলেও চার বছর ধরে দেখা এই গাছগুলোর নাম জিজ্ঞেস করা হলে হয়তো আমাদের উদ্ভিদবিজ্ঞানেরই অনেক ছাত্র …

INTRODUCTION Ascomycota is a phylum of fungi classification containing a compartmentalized mycelium, a dikaryotic life stage in the life cycle, plectenchymatous structures associated with spore production, conidia, and sometimes complex dispersal systems. The primitive morphological character that distinguishes members of Ascomycota from all other fungi is the Ascus (pl. asci, …

The male sterility which  is governed by both nuclear and cytoplasmic genes is known as Cytoplasmic Genetic Male Sterility or CGMS. While CMS is controlled by an extra-nuclear genome, nuclear gene may have the capability to restore fertility. When nuclear restoration of fertility genes (“Rf”) is available for a CMS …

Male sterility, as the name indicates, is the inability of a plant to produce a male reproductive organ, the viable pollen. Male sterility can occur due to extra-nuclear genetic or nuclear genetic conditions. Cytoplasmic Male Sterility (CMS) refers to the inability of a plant to produce viable pollens due to …
