Metabolic Acquisitions Through Laboratory Selection

“…An additional mutation observed in this strain was an apparently stable duplication of the previously evolved ACP-2 mutant acid phosphatase gene of strain M4, resulting in the synthe sis of incn:ased amounts of the enzyme (37,38).…”

Genetic Variability in Pecan Fruit Development

“…Productivity of young walnut orchards has been increased by the development of new precocious cultivars (2,4). This was accom plished by selecting clones which produced more pistillate flowers, especially on lateral branches.…”

“…1 ) control (nonsealed); 2) sealed in Clysar EH-60 (Du Pont) polyethylene film of 0.01 mm (0.6 mil) nominal thickness; 3) sealed in Clysar EHC-50 copolymer film of 0.013 mm (0.5 mil) nominal thickness; and 4) sealed in Clysar EHC-100 copolymer film of 0.025 mm (1.0 mil) nominal thickness. Refer to Hale et al (4) for properties of each film used. The plastic film was applied using a Weldotron sealer (model 6001), and it was shrunk tightly around the fruit using a Wel dotron heat tunnel (model 7001).…”
