AB  - Tomato cultivation is affected by high soil salinity and drought stress, which cause major yield losses worldwide. In this work, we compare the efficiency of mechanisms of tolerance to salinity, and osmotic stress applied as mannitol or drought, in three tomato genotypes: LA-2838 (Ailsa Craig), LA-2662 (Saladette), and LA-1996 (Anthocyanin  fruit  – Aft),  a  genotype  known  for  high  anthocyanin  content. Exposure  to  salinity  or   drought induced  stress  in  all three  genotypes,  but the  LA-1996 plants displayed  superior tolerance to stress compared with the other two genotypes. They were more efficient in anthocyanin and proline accumulation, superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT) activity, and leaf Na+, K+, and Ca2+ homeostasis. In addition, they suffered lesser oxidative damage as measured by chlorophyll (Chl) loss and malondialdehyde (MDA) accumulation, and bioassays showed that they were less affected in terms of seed germination and root elongation. Exposure to stress induced the upregulation of stress-related genes SlNCED1, SlAREB1, SlABF4, SlWRKY8, and SlDREB2A more efficiently in LA-1996 than in the two susceptible genotypes. Conversely, the upregulation of the NADPH oxidase gene SlRBOH1 was more pronounced in LA-2838 and LA-2662. Principal component analysis showed obvious distinction between the tolerant genotype LA-1996 and the susceptible LA- 2838 and LA-2662 in response to stress, and association of leaf and stem anthocyanin content with major stress tolerance traits. We suggest that anthocyanin accumulation can be considered as a marker of stress tolerance in tomato, and that LA-1996 can be considered for cultivation in salinity- or drought-affected areas.

AB  - Dung beetles have been used to enhance soil health and crop growth and yields, but their effects on
soil enzymology and microbial diversity are seldom reported. The present work reports on beneficial
effects of dung beetles on soil enzyme activity, bacterial diversity and growth and antioxidant content
of Chinese cabbage (Brassica rapa ssp. pekinensis). The soil amended with cow dung only (CD), or
with dung broken down by dung beetles (DB), was compared with untreated control (CO). Soil
bacterial diversity was determined through 16S rRNA gene sequencing, and enzymological tests were
used for soil enzyme activity. Dung beetles significantly increased acid phosphatase, urease,
cellulase, catalase and β-glucosidase activities in the soil compared with CD or control. Bacterial
alpha-diversity significantly increased in DB when compared with CD or control. Microbial carbon
(C) and nitrogen (N) were significantly higher in DB than in CD and in CD than control. The DB and
CD treatments also significantly enhanced plant growth and the content of antioxidants (total
flavonoids, polyphenols and vitamin C) and phytohormones indole-3-acetic acid (IAA), trans-zeatin
riboside (ZR) and gibberellic acid (GA3) compared with control, while a significant reduction was
noted in abscisic acid (ABA) in DB compared with CD or control plants. Correlation analysis
confirmed that the enzyme activities are pH dependent, as pH was significantly lowered by DB
compared with CD or control. Our results suggest that use of dung beetles in conventional practices
could be an effective strategy to improve soil nutrient availability and microbial activity and
antioxidant content of Chinese cabbage.
