- Archaeplastida abstract "The Archaeplastida (or Plantae sensu lato (in the broad sense)) are a major group of eukaryotes, comprising the red algae (Rhodophyta), the green algae and the land plants, together with a small group of freshwater unicellular algae called glaucophytes. The chloroplasts of the glaucophytes are surrounded by two membranes, suggesting they developed directly from endosymbiotic cyanobacteria. In all other groups, the chloroplasts are surrounded by three or four membranes, suggesting they were acquired secondarily from red or green algae.Although many studies have suggested that the Archaeplastida form a monophyletic group, a 2009 paper argues that they are in fact paraphyletic. The enrichment of novel red algal genes in a recent study demonstrates a strong signal for Plantae (Archaeplastida) monophyly and an equally strong signal of gene sharing history between the red/green algae and other lineages. This study provides insight on how rich mesophilic red algal gene data is crucial for testing controversial issues in eukaryote evolution and for understanding the complex patterns of gene inheritance in protists.The cells of the Archaeplastida typically lack centrioles and have mitochondria with flat cristae. There is usually a cell wall including cellulose, and food is stored in the form of starch. However, these characteristics are also shared with other eukaryotes in the Kingdom Plantae. The main evidence that the Archaeplastida form a monophyletic group comes from genetic studies, which indicate that their plastids probably had a single origin. This evidence is disputed. Photosynthetic organisms with plastids of different origin (like brown algae, for instance) do not belong to Archaeplastida.The archaeplastidans fall into two main evolutionary lines. The red algae are pigmented with chlorophyll a and phycobiliproteins, like most cyanobacteria. The green algae and land plants – together known as Viridiplantae (Latin for "green plants") or Chloroplastida – are pigmented with chlorophylls a and b, but lack phycobiliproteins. The glaucophytes have typical cyanobacterial pigments, and are unusual in retaining a cell wall within their plastids (called cyanelles).".
