Background: Electronic cigarettes (ECs) are handheld electronic vaping devices that produce an aerosol by heating an e-liquid. People who smoke, healthcare providers, and regulators want to know if ECs can help people quit smoking, and if they are safe to use for this purpose. This is a review update conducted as part of a living systematic review.

The degree of this sensitivity is crucial for determining the optimal planting regions for specific varieties, as well as for improving the quality and yield of tobacco leaves. However, the precise mechanisms underlying the development of photothermal sensitivity in tobacco remain unclear.

Tobacco is an economic crop that primarily relies on nitrate (NO) as its nitrogen source, and tobacco aphid is one of the significant pests that harm its growth. However, the impact of NO supply on the resistance of tobacco to aphids remains unclear. Present study investigated the effects of different NO concentrations supply on the reproductive capacity of tobacco aphids, impact of aphid infestation on tobacco growth, secondary metabolic and transcription changes.

Tomato yellow leaf curl virus (TYLCV) is a significant threat to tomato cultivation globally, transmitted exclusively by the whitefly Bemisia tabaci. While previous research suggests that the TYLCV C2 protein plays a role in fostering mutualistic interactions between the virus and its insect vectors, the specific mechanisms remain unclear. In this study, we show that the C2 protein interferes with the salicylic acid (SA) defence pathway by disrupting TCP7-like transcription factor-mediated regulation of TGA2 expression.

Introduction: Pregnant people who smoke constitute a uniquely vulnerable population likely to be impacted by a menthol cigarette (MC) ban. However, there are no published reports of prevalence of prenatal MC use in a nationally-representative US sample including racial-ethnic disparities and associated characteristics.
Methods: Participants were 1245 US pregnant people who smoked MC or non-MC (NMC) in the past 30-days from the 2010-2019 National Survey on Drug Use and Health.
