Is genetic diversity enhanced by a supergene?

Genetic Transformation of Oat Mediated by Agrobacterium is enhanced with Sonication and Vacuum Infiltration

Background: Oat (Avena sativa) with high nutritive value and fiber content is used as the main food grain in many countries for human diet as well as animal feed. Recently, it became difficult to transfer new genes through the conventional breeding due to the lack of desirable traits. Objectives: The current study aimed at achieving a st...

Jack-of-All-Trades “Supergene” Controls Butterfly Wing Pattern Diversity

October 2006 | Volume 4 | Issue 10 | e359 | e364 Fusion of two plasma membranes is central to exocytosis, the process by which a cell secretes neurotransmitters, digestive enzymes, and other products. If you believe the simple diagrams in introductory biology textbooks, you’d think this fusion occurs as soon as two membranes touch. Not so—in fact, membrane fusion requires interaction among a co...

Genetic diversity of Iranian melon cultigens revealed by AFLP markers

Iran is a part of the secondary centre of origin of melons, and therefore, there is a wealth of genetic variation of these species in this country. The Amplified Fragment Length Polymorphism (AFLP) marker was applied to investigate the genetic variations among five major Iranian melon cultigens (Cucumis melo) and ‘Ananasi’ as a general well-known cultivar. Ten primer pairs were used on 90 indiv...

A high genetic diversity revealed between commercial rose cultivars by RAPD-PCR technique

Genetic diversity between fifteen commercial cultivars of rose were evaluated, using Ten decamer primers (A-J). All primers detected polymorphism among the cultivars. In total, 126 bands were produced, 73 of which were polymorphic. Primers E and F produced the highest, while primer H produced the lowest number of bands. The percentage of polymorphic bands ranged from 37% to 81% with an average ...
