Nucleic Acids and Related Products

Examples of nucleic acids usually represent pathological situations - e.g., virus suspected in blackline disease of walnuts (Juglans nigra). Roles of extracellular calcium, ATPases and nucleotides are uncertain. No good evidence exists that nucleic acids or nucleotides are found extracellular to cell walls except under stress or injury (Sect. 5.1.3.4). 

Nevertheless, to the molecular geneticist, the field of lignin biodegradation is now open for study through the use of enzymes and nucleic acids. Gene sequences of cellobiohydrolase and the cloning of hydrolytic cellulases have been reported (Sect. 5.1.3.5).

The natural occurrence and the role of free and bound amino acids, proteins, nucleic acids, and related products (e.g., 8, 42, 116) are described in relation to factors determining the composition of the lignocellulosic cell wall. The biosynthesis of extraneous nitrogenous compounds involves a sequence of events that stem from molecular reactions inside cells, on the surfaces of cells, and in the soluble component of plant cell walls.
