Catalytic Domains. The catalytic domain of CenB (amino acids 1 - 608) shows 35% sequence identity with an endoglucanase from Persea americana (avocado) it has therefore been placed in family E, subfamily 2 (2,3). The CenC catalytic domain (amino acids 299-809) shows 28% sequence identity with Clostridium thermocellum endoglucanase D (EGD) and 43% identity with P. fluorescens endoglucanase A (End A), both members of family E, subfamily 1 (2,3). 

Alkyl furans are another class of naturally occurring compounds with insecticidal activity (Fig. 13)- This group of compounds, commonly referred to as avocado furans is present in avocados, Persea americana (Lau-raceae) and related plants. When tested against beet armyworm, Spodoptera... 

Certain crops require a special climate and soil. Plants native to the American tropical rain forest give coca (Erythroxylum cocoa), avocado (Persea americana), the American counterpart of the mango (Spondias mombin), guava (Psidium guqjava), papaya (Carica papaya), the Brazilian nut (Bertholletia excelsa), and chewing-gum (latex om Achras sapota).

The cell walls of the vessels in Persea wood have reacted to the coalifying processes in a way that is different from the response of the fiber-tracheid walls, even though the two wall types may lie in juxtaposition. Microscopic study of thin sections, cut on a microtome, show that the vessel walls are yellow-tan in color, anisotropic, and morphologically intact though often deformed. In contrast, the fiber-tracheid walls have been converted to a yellow-brown to orange-brown, isotropic material that exhibits little of the original...

Note that these peats varied considerably in their botanical compositions. The Minnesota peat consisted predominantly of Sphagnum (peat moss) debris with some grasses and conifers. The Maine peat was composed mostly of algal material with some Sphagnum and Nymphaea (water lily) debris. The North Carolina peat was dominated by bay tree (Magnolia, Persea, Gordonia) and gum tree (Nyssa) debris while the Georgia Nymphaea peat consisted predominantly of Nymphaea debris.
