TL;DR: A new perspective on the potential mechanism by which SFAs could modulate TLR4-induced inflammatory responses is provided, which plays a crucial role in the induction of inflammatory mediators implicated in the development and progression of many chronic diseases.

TL;DR: In this article, the effects of water deficit on photochemical parameters and activities of superoxide dismutase (SOD), catalase (CAT), and ascorbate peroxidase (APX), as well as, cellular damages were investigated in two clones of Coffea canephora differing in drought tolerance.

TL;DR: Genomic selection brings a new perspective to the understanding of quantitative trait variation in forest trees and provides a revolutionary tool for applied tree improvement, although population-specific predictive models will likely drive the initial applications of GS in forest tree breeding.
Abstract: Summary •Genomic selection (GS) is expected to cause a paradigm shift in tree breeding by improving its speed and efficiency By fitting all the genome-wide markers concurrently, GS can capture most of the ‘missing heritability’ of complex traits that quantitative trait locus (QTL) and association mapping classically fail to explain Experimental support of GS is now required •The effectiveness of GS was assessed in two unrelated Eucalyptus breeding populations with contrasting effective population sizes (Ne = 11 and 51) genotyped with > 3000 DArT markers Prediction models were developed for tree circumference and height growth, wood specific gravity and pulp yield using random regression best linear unbiased predictor (BLUP) •Accuracies of GS varied between 055 and 088, matching the accuracies achieved by conventional phenotypic selection Substantial proportions (74–97%) of trait heritability were captured by fitting all genome-wide markers simultaneously Genomic regions explaining trait variation largely coincided between populations, although GS models predicted poorly across populations, likely as a result of variable patterns of linkage disequilibrium, inconsistent allelic effects and genotype × environment interaction •GS brings a new perspective to the understanding of quantitative trait variation in forest trees and provides a revolutionary tool for applied tree improvement Nevertheless population-specific predictive models will likely drive the initial applications of GS in forest tree breeding

TL;DR: It is found that defaunation has the potential to significantly erode carbon storage even when only a small proportion of large-seeded trees are extirpated, a serious risk for the maintenance of tropical forest carbon storage.
Abstract: Carbon storage is widely acknowledged as one of the most valuable forest ecosystem services. Deforestation, logging, fragmentation, fire, and climate change have significant effects on tropical carbon stocks; however, an elusive and yet undetected decrease in carbon storage may be due to defaunation of large seed dispersers. Many large tropical trees with sizeable contributions to carbon stock rely on large vertebrates for seed dispersal and regeneration, however many of these frugivores are threatened by hunting, illegal trade, and habitat loss. We used a large data set on tree species composition and abundance, seed, fruit, and carbon-related traits, and plant-animal interactions to estimate the loss of carbon storage capacity of tropical forests in defaunated scenarios. By simulating the local extinction of trees that depend on large frugivores in 31 Atlantic Forest communities, we found that defaunation has the potential to significantly erode carbon storage even when only a small proportion of large-seeded trees are extirpated. Although intergovernmental policies to reduce carbon emissions and reforestation programs have been mostly focused on deforestation, our results demonstrate that defaunation, and the loss of key ecological interactions, also poses a serious risk for the maintenance of tropical forest carbon storage.
