Plastid genomics in horticultural species: Importance and applications for plant diversity, evolution and biotechnology

Frontiers in Plant Science, 2015
During the evolution of the eukaryotic cell, plastids and mitochondria arose from an endosymbiotic process, which determined the presence of three genetic compartments into the incipient plant cell. After that, these three genetic materials from host and

Petrocodon gracilis (Gesneriaceae) is a synonym of P. mirus based on morphological and molecular data

Nordic Journal of Botany, EarlyView.
Petrocodon gracilis T.Ding & B.Pan and P. mirus X.Z.Shi, J.X.Fu & Li H.Yang are two recently described species exhibiting nearly identical morphology. To determine whether they represent the same taxon, we compared their type localities, type materials, and morphological features and conducted phylogenetic analyses using the nuclear internal ...

A functional RNase P protein subunit of bacterial origin in some eukaryotes [PDF]

, 2011
RNase P catalyzes 5′-maturation of tRNAs. While bacterial RNase P comprises an RNA catalyst and a protein cofactor, the eukaryotic (nuclear) variant contains an RNA and up to ten proteins, all unrelated to the bacterial protein.

Secrets within stems: The cryptic Apodanthes caseariae (Apodanthaceae), a rare neotropical holoendoparasite

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.

The complete plastid genome sequence of the parasitic green alga Helicosporidium sp. is highly reduced and structured

BMC Biology, 2006
Background Loss of photosynthesis has occurred independently in several plant and algal lineages, and represents a major metabolic shift with potential consequences for the content and structure of plastid genomes.

Comparative Plastome Analysis of <i>Artocarpus</i> Species in China: Insight Into Adaptive Evolution and Mutational Hotspot Regions. [PDF]

Ecol Evol
The initial comparative plastome analysis of 10 Artocarpus species in China lays the groundwork for regional evolutionary research. Investigated of inverted repeat (lR) boundary variations, particularly the incomplete duplication of the ycf1 gene, elucidating mechanisms underlying genomic divergence.

Plastid redox state and sugars: Interactive regulators of nuclear-encoded photosynthetic gene expression [PDF]

, 2001
Feedback regulation of photosynthesis by carbon metabolites has long been recognized, but the underlying cellular mechanisms that control this process remain unclear.

First genome sequence of a European Alternaria brassicae isolate and genes involved in early development of alternaria leaf spot on Brassica juncea

Pest Management Science, EarlyView.
This article reports the first genome sequence of a UK Alternaria brassicae isolate. Dual RNA‐sequencing profiling of A. brassicae‐infected Brassica juncea leaves identified differentially expressed genes involved in pathogenicity and host response pathways in moderately resistant Sej‐2 (2) and moderately susceptible Pusa Jaikisan cultivars.

Degradation of key photosynthetic genes in the critically endangered semi-aquatic flowering plant Saniculiphyllum guangxiense (Saxifragaceae)

BMC Plant Biology, 2020
Background Plastid gene loss and pseudogenization has been widely documented in parasitic and mycoheterotrophic plants, which have relaxed selective constraints on photosynthetic function.

Strategies for complete plastid genome sequencing

Molecular Ecology Resources, 2016
Plastid sequencing is an essential tool in the study of plant evolution. This high‐copy organelle is one of the most technically accessible regions of the genome, and its sequence conservation makes it a valuable region for comparative genome evolution ...
