Arabidopsis DAL1 and DAL2, two RING finger proteins homologous to Drosophila DIAP1, are involved in regulation of programmed cell death

Abstract: Programmed cell death (PCD) is a precise, genetically controlled cellular process with important roles in plant growth, development, and response to biotic and abiotic stress. However, the genetic mechanisms that control PCD in plants are unclear. Two Arabidopsis genes, DAL1 and DAL2 (for Drosophila DIAP1 like 1 and 2), encoding RING finger proteins with homology to DIAP1 were identified, and a series of experiments were performed to elucidate their roles in the regulation of PCD and disease resistance.

“…Another study reported that SP1 (DAL1) and SPL1 (DAL2) are involved in the regulation of reactive oxygen species (ROS) accumulation and programmed cell death (52). A more recent study showed that SP1 promotes stress tolerance by depleting TOC components, leading to diminished ROS produced in photosynthesis (53).…”

“…This suggests that the turnover of TOC components was affected. Our previous studies have found that the sterile anther in 7365A displays delayed tapetal programmed cell death (PCD) Zhou et al, 2011;Song et al, 2016), and another study reported that SP1 is involved in the regulation of PCD (Basnayake et al, 2011). So, SP1 mediating UPS may be affected in 7365A.…”
