Lack of conservation of bacterial type promoters in plastids of Streptophyta [PDF]
Biology Direct, 2010 We demonstrate the scarcity of conserved bacterial-type promoters in plastids of Streptophyta and report widely conserved promoters only for genes psaA, psbA, psbB, psbE, rbcL. Among the reasonable explanations are: evolutionary changes of sigma subunit paralogs and phage-type RNA polymerases possibly entailing the loss of corresponding nuclear genes ...

Can Repeated Reductive Genome Evolution Across Archaeplastida Explain Volatility in Traits? [PDF]
Adv Genet (Hoboken)Genome evolution in Archaeplastida is often framed around gene gains and increasing complexity. Yet ancestral reconstructions reveal recurrent genome contraction, with ancestors frequently harboring larger gene repertoires than descendants. Across red algae, land‐plant ancestry, and embryophyte diversification, repeated expansion and reduction cycles ...

A clade uniting the green algae
BMC Biology, 2007 Background The Viridiplantae comprise two major phyla: the Streptophyta, containing the charophycean green algae and all land plants, and the Chlorophyta, containing the remaining green algae.

Circadian Oscillations in Branchlet Angle and Irradiance‐Dependent Acclimation in Chara braunii Under Continuous Light [PDF]
Plant DirectABSTRACT Endogenous biological rhythms are central to temporal organization in land plants, yet their evolutionary origins in streptophyte algae remain unresolved. We investigated whether rhythmic morpho‐physiological processes in Chara braunii are consistent with endogenous regulation and how continuous light intensity modulates these responses. In C.

Hidden genetic diversity in the green alga
BMC Evolutionary Biology, 2012 Background The unbranched filamentous green alga Spirogyra (Streptophyta, Zygnemataceae) is easily recognizable based on its vegetative morphology, which shows one to several spiral chloroplasts.
