Wi-Fi Protected Access is a subset of and will be compatible with IEEE 802.11i (sometimes referred to as WPA2), a security standard under development. Software updates that will allow both server and client computers to implement WPA are expected to become widely available during 2003.
Most plant lectins are storage proteins and defence proteins when the plant or the seed is assaulted by insects or fungi (Janzen et al. Plant lectins are a unique group of proteins and glycoproteins with potent biological activities.
Pectin is a major component of the middle lamella, where it helps to bind cells together, but is also found in primary cell walls. The amount, structure and chemical composition of pectin differs among plants, within a plant over time, and in various parts of a plant. Pectin is an important cell wall polysaccharide that allows primary cell wall extension and plant growth. During fruit ripening, pectin is broken down by the enzymes pectinase and pectinesterase, in which process the fruit becomes softer as the middle lamellae break down and cells become separated from each other.
