Abstract:
Coexpression of a plant NB-LRR-type resistance (R) gene and corresponding viral avirulent (Avr) gene introduced in Nicotiana benthamiana using Agrobacterium tumefaciens confers hypersensitive response (HR). Such Agrobacterium-mediated transient gene expression methods have contributed to the identification of new plant R genes and facilitated the analysis of their functions. Here we describe a model method, by which several tobamovirus R genes from Solanaceous plants have been successfully identified and characterized molecularly.

Loss of Tumor Suppressor Gene Functions
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

Overview of Advanced Functional Groups
Functional groups are groups of atoms with specific chemical properties that occur within organic molecules and are sometimes denoted as “R”. Functional groups can “functionalize” a compound by enabling it to adopt different physical and chemical properties.
Types of Advanced Functional Groups
The table below summarizes some of the major functional groups in organic chemistry.
