AhASRK1, a peanut dual-specificity kinase that activates the Ca-ROS-MAPK signalling cascade to mediate programmed cell death induced by aluminium toxicity via ABA.

Aluminium (Al)-induced programmed cell death (PCD) is thought to be a main cause of Al phytotoxicity. However, the underlying mechanism by which Al induces PCD in plants is unclear. In this study, we characterized the function of AhASRK1 (Aluminum Sensitive Receptor-like protein Kinase1), an Al-induced LRR-type receptor-like kinase gene.

Host-Induced Gene Silencing of the -Methyl Transferase Gene Enhanced Maize Aflatoxin Resistance.

Maize is one of the major crops that are susceptible to infection and subsequent aflatoxin contamination, which poses a serious health threat to humans and domestic animals. Here, an RNA interference (RNAi) approach called Host-Induced Gene Silencing (HIGS) was employed to suppress the -methyl transferase gene (, also called ), a key gene involved in aflatoxin biosynthesis. An RNAi vector carrying part of the gene was introduced into the B104 maize line.

Resistance to Aflatoxin Accumulation in Maize Mediated by Host-Induced Silencing of the Alkaline Protease () Gene.

is a fungal pathogen that infects maize and produces aflatoxins. Host-Induced Gene Silencing (HIGS) has been shown to reduce host infection by various fungal pathogens. Here, the alkaline protease () gene was targeted for silencing through HIGS.

Host Induced Gene Silencing Targeting Reduced Aflatoxin Contamination in Transgenic Maize Under Field Conditions.

Maize ( L.) is one of the major crops susceptible to infection and subsequent contamination with aflatoxins, the most potent naturally produced carcinogenic secondary metabolites. This pathogen can pose serious health concerns and cause severe economic losses due to the Food and Drug Administration (FDA) regulations on permissible levels of aflatoxins in food and feed.
