The non-photosynthetic, pathogenic green alga Helicosporidium sp. has retained a modified, functional plastid genome [PDF]
, 2004 A fragment of the Helicosporidium sp. (Chlorophyta: Trebouxiophyceae) plastid genome has been sequenced. The genome architecture was compared to that of both a non-photosynthetic relative (Prototheca wickerhamii) and a photosynthetic relative (Chlorella ...

Taxonomy and diversity of Marcgraviaceae, north of the São Francisco river, northeast Brazil
Nordic Journal of Botany, EarlyView.This study provides a comprehensive assessment of Marcgraviaceae species diversity north of the São Francisco river in northeastern Brazil, analyzing species richness and distribution patterns across 384 000 km² of phytogeographic domains. Through field collections, herbarium studies (both physical and digital), and detailed morphological analyses, we ...

PLANTS, PEOPLE, PLANET, EarlyView.Holoendoparasites are extremely rare plants that live entirely hidden inside their hosts, with only flowers and fruits visible. We studied Apodanthes caseariae, found in central and South America, parasitizing Casearia sylvestris. Little is known about its life cycle.

Parallel evolution of highly conserved plastid genome architecture in red seaweeds and seed plants
BMC Biology, 2016 BackgroundThe red algae (Rhodophyta) diverged from the green algae and plants (Viridiplantae) over one billion years ago within the kingdom Archaeplastida.

PLANTS, PEOPLE, PLANET, EarlyView.Climate extremes threaten the sustainability of cranberry production, a culturally and economically important North American crop. This study demonstrates that wild cranberries (Vaccinium oxycoccos) harbor genetic variation that may enhance cold stress resilience when introduced into cultivated cranberry through hybridization.

Evidence for a role of Arabidopsis CDT1 proteins in gametophyte development and maintenance of genome integrity [PDF]
, 2012 Meristems retain the ability to divide throughout the life cycle of plants, which can last for over 1000 years in some species. Furthermore, the germline is not laid down early during embryogenesis but originates from the meristematic cells relatively ...
