Coumarinolignoid and Indole Alkaloids from the Roots of the Hybrid Plant Citrus x paradisi Macfad. (Rutaceae).
A phytochemical investigation of the roots of Citrus x paradisi Macfad. (Rutaceae) led to the isolation of two new compounds, namely 1-formyl-5-hydroxy-N-methylindolin-1-ium (1) and decyloxycleomiscosin D (2), along with ten known compounds: 1,1-dimethylpyrrolidin-1-ium-2-carboxylate (3), furan-2,3-diol (4), 5-methoxyseselin (5), umbelliferone (6), scopoletin (7), citracridone I (8), citracridone II (9), citracridone III... -

Phylogenetic, Developmental and Functional Aspects of Stomatal Patterning: Lessons from Magnoliids.
The magnoliid clade encompasses 18 extant families arranged in four orders, plus several extinct taxa, including some of the most ancient angiosperm fossils. The clade is characterized by paracytic stomata with a distinct pair of lateral subsidiary cells that flank the guard cells, though other stomatal types are also reported,...Rudall, Paula J.

Seed Longevity—The Evolution of Knowledge and a Conceptual Framework.
The lifespan or longevity of a seed is the time period over which it can remain viable. Seed longevity is a complex trait and varies greatly between species and even seed lots of the same species.

Genetic assimilation of ancestral plasticity during parallel adaptation to zinc contamination in Silene uniflora.
Phenotypic plasticity in ancestral populations is hypothesized to facilitate adaptation, but evidence is piecemeal and often contradictory. Further, whether ancestral plasticity increases the probability of parallel adaptive changes has not been explored. The most general finding is that ancestral responses to a new environment are reversed following adaptation (known as... -

The role of the tryptophan-NAD + pathway in a mouse model of severe malnutrition induced liver dysfunction.
Mortality in children with severe malnutrition is strongly related to signs of metabolic dysfunction, such as hypoglycemia. Lower circulating tryptophan levels in children with severe malnutrition suggest a possible disturbance in the tryptophan-nicotinamide adenine dinucleotide (TRP-NAD+) pathway and subsequently in NAD+ dependent metabolism regulator sirtuin1 (SIRT1). Here we show that...Hu, Guanlan ; Ling, Catriona ; Chi, Lijun ; Thind, Mehakpreet K. ; Furse, Samuel …

Characterisation of the Paternal Influence on Intergenerational Offspring Cardiac and Brain Lipid Homeostasis in Mice.

Metagenomics Shines Light on the Evolution of ‘Sunscreen’ Pigment Metabolism in the Teloschistales (Lichen-Forming Ascomycota).
Fungi produce a vast number of secondary metabolites that shape their interactions with other organisms and the environment. Characterising the genes underpinning metabolite synthesis is therefore key to understanding fungal evolution and adaptation. Lichenised fungi represent almost one-third of Ascomycota diversity and boast impressive secondary metabolites repertoires. However, most lichen... -

Morphological Continua Make Poor Species: Genus-Wide Morphometric Survey of the European Bee Orchids (Ophrys L.).
Despite (or perhaps because of) intensive multidisciplinary research, opinions on the optimal number of species recognised within the Eurasian orchid genus Ophrys range from nine to at least 400. The lower figure of nine macrospecies is based primarily on seeking small but reliable discontinuities in DNA ‘barcode’ regions, an approach... -

First evidence of a monodominant (Englerodendron, Amherstieae, Detarioideae, Leguminosae) .tropical moist forest from the early Miocene (21.73 Ma) of Ethiopia

But, dominance by a single canopy species can also occur in tropical wet climates and can remain stable for centuries. These are uncommon globally, with the African wet tropics supporting more such communities than the Neotropics or... -
