Cadmium-mediated toxicity in plant cells is associated with the DCD/NRP-mediated cell death response.

Article Synopsis
- Cadmium (Cd) negatively affects plant growth, causing issues such as leaf yellowing and chlorosis, particularly during the reproductive stage of soybean.
- Cd triggers programmed cell death (PCD) in plant cells, characterized by increased cell death, DNA damage, and specific signaling proteins (GmNAC81, GmNAC30, and VPE) that facilitate this process.
- The study suggests that overexpressing GmNAC81 worsens Cd stress effects, while overexpressing BiP can provide tolerance to Cd, highlighting the complex interactions in plant responses to cadmium toxicity.
Background: The Geminiviridae family encompasses a group of single-stranded DNA viruses with twinned and quasi-isometric virions, which infect a wide range of dicotyledonous and monocotyledonous plants and are responsible for significant economic losses worldwide. Geminiviruses are divided into nine genera, according to their insect vector, host range, genome organization, and phylogeny reconstruction. Using rolling-circle amplification approaches along with high-throughput sequencing technologies, thousands of full-length geminivirus and satellite genome sequences were amplified and have become available in public databases.

Among plant species and among cultivars within species a natural variation in uptake, translocation and distribution of trace elements occur. The transference of Cd and Zn, from soil to two lettuce (Lactuca sativa L.
