 Abstract
-
Backfat thickness (BF) is an important indicator of fat deposition
capacity and lean meat rate in pigs and is very important
in porcine genetics and breeding. Intestinal microbiota
plays a key role in nutrient digestion and utilization with a
profound impact on fat deposition of livestock animals. To
investigate the relationship between the pig gut microbiome
and BF, 20 low-BF (L-BF) and 20 high-BF (H-BF) pigs were
selected as two groups from Yunong Black pigs in the present
study. Fecal samples from pigs were analyzed for microbial
diversity, composition, and predicted functionality using 16S
rRNA gene sequencing. The results showed that there were
significant differences in microbial β diversity between the
two groups. LEfSe analysis revealed a number of bacterial features
being differentially enriched in either L-BF or H-BF pigs.
Spearman correlation analysis identified the abundance of
Oscillospira, Peptococcus, and Bulleidia were significantly
positive correlations with BF (P < 0.05), while Sutterella and
Bifidobacterium were significantly negatively correlated with
BF (P < 0.05). Importantly, the bacteria significantly positively
correlated with BF mainly belong to Clostridium, which can
ferment host-indigestible plant polysaccharides into shortchain
fatty acid (SCFA) and promote fat synthesis and deposition.
Predictive functional analysis indicated that the pathway
abundance of cell motility and glycan biosynthesis were
significantly widespread in the microbiota of the H-BF group.
The results of this study will be useful for the development of
microbial biomarkers for predicting and improving porcine
BF, as well as for the investigation of targets for dietary strategies.

Abstract
-
Infection by Sclerotium rolfsii will cause serious disease and
lead to significant economic losses in chili pepper. In this
study, the response of pepper during S. rolfsii infection was
explored by electron microscopy, physiological determination
and integrated proteome and metabolome analyses. Our results
showed that the stomata of pepper stems were important
portals for S. rolfsii infection. The plant cell morphology
was significantly changed at the time of the fungal hyphae just
contacting (T1) or surrounding (T2) the pepper. The chlorophyll,
carotenoid, and MDA contents and the activities of
POD, SOD, and CAT were markedly upregulated at T1 and
T2. Approximately 4129 proteins and 823 metabolites were
clearly identified in proteome and metabolome analyses, respectively.
A change in 396 proteins and 54 metabolites in
pepper stem tissues was observed at T1 compared with 438
proteins and 53 metabolites at T2. The proteins and metabolites
related to photosynthesis and antioxidant systems in
chloroplasts and mitochondria were disproportionally affected
by S. rolfsii infection, impacting carbohydrate and amino
acid metabolism. This study provided new insights into the
response mechanism in pepper stems during S. rolfsii infection,
which can guide future work on fungal disease resistance
breeding in pepper.

Abstract
-
Reactive oxygen species (ROS) produced by NADPH oxidases
can serve as signaling molecules to regulate a variety of
physiological processes in multi-cellular organisms. In the
nematophagous fungus Arthrobotrys oligospora, we found
that ROS were produced during conidial germination, hyphal
extension, and trap formation in the presence of nematodes.
Generation of an AoNoxA knockout strain demonstrated
the crucial role of NADPH oxidase in the production
of ROS in A. oligospora, with trap formation impaired in
the AoNoxA mutant, even in the presence of the nematode
host. In addition, the expression of virulence factor serine
protease P186 was up-regulated in the wild-type strain, but
not in the mutant strain, in the presence of Caenorhabditis
elegans. These results indicate that ROS derived from AoNoxA
are essential for full virulence of A. oligospora in nematodes.
