Hydrogen sulfide enhances cadmium tolerance in oilseed rape roots by augmenting glutathione-mediated antioxidant defense and ROS homeostasis.

Hydrogen sulfide (HS) plays a crucial role in regulating plant development and stress responses. Here, the potential role of HS in enhancing cadmium (Cd) tolerance by modulating the antioxidant defense system and reactive oxygen species (ROS) homeostasis was investigated. The results shown that Cd (II) exposure significantly inhibited the growth and chlorophyll content of rapeseed seedlings.

Multiomics and biotechnologies for understanding and influencing cadmium accumulation and stress response in plants.

Cadmium (Cd) is one of the most toxic heavy metals faced by plants and, additionally, via the food chain, threatens human health. It is principally dispersed through agro-ecosystems via anthropogenic activities and geogenic sources. Given its high mobility and persistence, Cd, although not required, can be readily assimilated by plants thereby posing a threat to plant growth and productivity as well as animal and human health.

Identification and Expression Analysis of Gene Family in L.

Dihydroflavonol 4-reductase () is a key enzyme in the flavonoid biosynthetic pathway and is essential for the formation of plants' color. In this study, 26 genes were identified using 6 genes as reference. The physicochemical properties, subcellular localization, and conserved structure of proteins were analyzed; the evolutionary relationship, collinearity analysis, and expression characteristics of genes were studied; and the correlation between the expression level of genes and anthocyanin content in rape petals were analyzed.

Nitrate reductase is required for sclerotial development and virulence of .

, the causal agent of Sclerotinia stem rot (SSR) on more than 450 plant species, is a notorious fungal pathogen. Nitrate reductase (NR) is required for nitrate assimilation that mediates the reduction of nitrate to nitrite and is the major enzymatic source for NO production in fungi. To explore the possible effects of nitrate reductase SsNR on the development, stress response, and virulence of , RNA interference (RNAi) of was performed.

Sodium hydrosulfide alleviates aluminum toxicity in Brassica napus through maintaining HS, ROS homeostasis and enhancing aluminum exclusion.

Hydrogen sulfide (HS) is a gaseous mediator that plays versatile roles in plant growth and stress responses. However, the regulatory functions of HS in plant responses to aluminum (Al) stress remain elusive. We observed that application of 20 μM of NaHS (HS donor) or 0.

Alleviating dormancy in Brassica oleracea seeds using NO and KAR1 with ethylene biosynthetic pathway, ROS and antioxidant enzymes modifications.

Background: Seed dormancy is a prevailing condition in which seeds are unable to germinate, even under favorable environmental conditions. Harvested Brassica oleracea (Chinese cabbage) seeds are dormant and normally germinate (poorly) at 21 °C. This study investigated the connections between ethylene, nitric oxide (NO), and karrikin 1 (KAR1) in the dormancy release of secondary dormant Brassica oleracea seeds.

Sodium Hydrosulfide Mitigates Cadmium Toxicity by Promoting Cadmium Retention and Inhibiting Its Translocation from Roots to Shoots in Brassica napus.

The association between hydrogen sulfide (HS) and cell wall composition with regard to the mitigation of cadmium (Cd) toxicity in Brassica napus L. was investigated. Cd caused growth retardation, leaf chlorosis, and decreased endogenous HS content in Brassica napus roots.
