Molecular and physiological characterization of bread wheat (Triticum aestivum L.) breeding lines for fungal diseases tolerance

Fungal diseases are one of the major causes of losses on wheat yield in the world. Recent studies on plant defense mechanisms have highlighted the role of amino acids and total polyphenols in disease tolerance. Thus, with the objective of identifying on the basis of morphological and physiological variables the high-performance wheat accessions in high and low altitude, we characterized sixteen wheat accessions via...

Some physicochemical properties of tyrosinase from sweet potato (Ipomea batatas)

Tyrosinase catalyzes formation of browning in plants, foods and vegetables. Sweet potato (Ipomea batatas) undergoes browning after harvesting or during post-harvest operations leading to spoilage and loss of economic value. The physico-chemical properties of purified tyrosinase from I. batatas are here described with a view to providing information on the suitability or otherwise of the enzyme for several industrial and...

Engineering of high production of salicylic acid in transgenic hairy roots of Marigold Calendula officinalis L. by Agrobacterium rhizogenes ATCC 13332

This study is directed to engineering the high production of salicylic acid from both genetically transformed hairy roots and callus cultures of Marigold, Calendula officinalis L., by pRi-DNA plasmid of the wild type Agrobacterium rhizogenes ATCC 13332, via "Direct injection" and "Co-cultivation" techniques. High frequency of transformed hairy roots was recorded as leaves were inoculated by mixture...
