The independent transition to a heterotrophic lifestyle in plants drove remarkably convergent evolutionary trajectories, characterized by morphological modifications and reductions their plastomes. characteristics of the minimum plastome required for survival, if they exist, remain topic debate. holoparasitic family Balanophoraceae was initially presumed have entirely lost plastids, however, recent reports revealed presence reduced aberrant plastids with odd genomes. Among outstanding...
Although horizontal gene transfer (HGT) is common in angiosperm mitochondrial DNAs (mtDNAs), few cases of functional foreign genes have been identified. The one outstanding candidate for large-scale HGT the holoparasite Lophophytum mirabile, whose mtDNA has lost most native but contains intact homologs acquired from legume host plants. To investigate extent to which this situation results replacement by genes, nucleus, and/or loss biochemical function context extreme parasitism, we examined...
Abstract Multichromosomal mitochondrial genomes (mtDNAs) in eukaryotes exhibit remarkable structural diversity, yet intraspecific variability and the origin of individual chromosomes remain poorly understood. We focus on a holoparasitic angiosperm with an mtDNA consisting 65 largely composed foreign DNA acquired by horizontal gene transfer (HGT) from its mimosoid hosts. The frequency, timing population dynamics these HGT events have not been examined. Here, we sampled different individuals...
Mitonuclear incompatibility results from a breakdown of the coordinated function between co-evolved genes located in nuclear and mitochondrial compartments. Horizontal Gene Transfer (HGT), involving acquisition unrelated species, can trigger mitonuclear incompatibilities when foreign gene products interact with native ones, particularly multisubunit complexes. Recent findings highlighted rampant HGT genomes holoparasitic plants genus Lophophytum (Balanophoraceae). In Lophophytum, some...
Helosis cayennensis (Balanophoraceae s.str.) is a holoparasite characterised by aberrant vegetative bodies and tiny, reduced unisexual flowers. Here, we analysed the development of female flowers to elucidate their morpho-anatomy historical controversy on embryo sac formation. We also studied developmental origin inflorescences ontogeny fruits, endosperm discussed in phylogenetic framework. Inflorescences were optical, fluorescence scanning electron microscopy. H. arise endogenously. Female...
The objectives of this work were to study the structure vegetative body Lophophytum mirabile subsp. bolivianum (Wedd.) B. Hansen, analyze change on roots Anadenanthera colubrina var. cebil (Griseb.) Altschul when they are infected by parasitic plant, and identify anatomical changes produced that parasitism. L. plants formed a spheroidal-narrower underground or tuber, externally has dark warty surface;epidermis, stomata trichomes lacking. central matrix tuber consists reserving parenchyma...
En el marco de la tendencia global hacia accesibilidad las bases datos, reseñamos los protocolos diseñados para confección del muestrario y colección histológica utilizados en estudio arqueobotánico patrimonio culinario Centro-Surandino, así como su sistematización puesta a disposición digital. El herbario etnoarqueológico, e histoteca que integran Herbario JUA están compuestos, por un lado, ejemplares cultivos andinos provenientes agricultura familiar pequeña escala sector centro centro-sur...
Lophophytum species are holoparasites that grow on tree roots. The objectives of the work were to explore chemical composition tubers two and analyze antioxidant, anti-inflammatory antilithiatic activity their extracts using in vitro methods. was determined by histochemical, phytochemical TLC tests. In addition, profile phenolic compounds HPLC-MS. presence secondary metabolites recognized demonstrated. results HPLC-MS/MS allowed tentative identification catechin, luteolin glycosides...
Pilostyles, an endoparasitic genus within the Apodanthaceae family, grows inside host stems with flowers and fruits being only external manifestations. Previous studies of P. berteroi growing on Adesmia trijuga provided limited details endophyte omitted origin sinker structure. This study, using classical methods optical microscopy applied to analysis scanning electron confocal laser microscopy, expands understanding berteroi/A. complex. We find that develops isophasically its host, forming...
