Inoculation Stimulates Endophytic Population and Induces Systemic Resistance to Bacterial Wilt.

Bacterial communities in the rhizosphere play an important role in sustaining plant growth and the health of diverse soils. Recent studies have demonstrated that microbial keystone taxa in the rhizosphere microbial community are extremely critical for the suppression of diseases. However, the mechanisms involved in disease suppression by keystone species remain unclear.

First Report of Bacterial Rot Caused by Pantoea endophytica on Tobacco in Liuyang, China.

Tobacco, Nicotiana tabacum L., is produced largely in China (~1/3 of the global market). In the monsoon summer of 2020, tobacco plant petioles, where axillary buds were removed, became black-rotten, and thick ooze appeared, when squeezed.

Combined effects of elevated CO concentration and on (Araneae: Linyphiidae).

The increasing concentration of carbon dioxide in atmosphere is not only a major cause of global warming, but it also adversely affects the ecological diversity of invertebrates. This study was conducted to evaluate the effect of elevated CO concentration (ambient, 400 ppm and high, 800 ppm) and (-infected, W and -uninfected, W) on . The total survival rate, developmental duration, carapace width and length, body weight, sex ratio, net reproductive rate, nutrition content, and enzyme activity in were examined under four treatments: W 400 ppm, W 800 ppm, W 400 ppm, and W 800 ppm.
