Abstract

Two genes recently identified in Arabidopsis thaliana may be involved in sequestering free copper ions in the cytoplasm and delivering copper to post-Golgi vesicles. The genes COPPER CHAPERONE and RESPONSIVE TO ANTAGONIST1 are homologous to copper-trafficking genes from yeast and humans. This plant copper-delivery pathway is required to create functional ethylene receptors. The pathway may also facilitate the transport of copper from senescing leaf tissue. In addition, several other genes have been identified recently that may have a role in copper salvage during senescence.

Bimodal retrograde signaling disrupts a suppressor network and activates a key transcriptional activator to direct stress responses.

Plastid-to-nucleus communication, crucial for regulating stress-responsive gene expression, has long intrigued researchers. This study reveals how the plastidial metabolite 2-C-methyl-D-erythritol-2,4-cyclopyrophosphate (MEcPP) orchestrates transcriptional reprogramming by modulating the rapid stress response element (RSRE), a conserved regulatory hub in the plant general stress response network. Yeast one-hybrid assays identified HAT1, a class II HD-Zip protein, as a negative regulator of RSRE. Genetic analyses, including HAT1 overexpression and knockdowns, confirmed its role in suppressing RSRE activity. Interaction assays uncovered a suppression network involving HAT1, the co-repressor TOPLESS (TPL), and the nuclear importin IMPα-9. Furthermore, HAT1 interacts with calmodulin-binding transcription activator 3 (CAMTA3), a calcium/calmodulin-binding transcription factor known to activate RSRE. AlphaFold modeling provided insights into the architecture of the HAT1-RSRE complex and HAT-CAMTA3 interaction, supported by conserved domains across plant species. Under stress condition, MEcPP accumulation promotes the 26S proteasomal degradation of TPL and IMPα-9 while reduces auxin-dependent HAT1 expression. Additionally, MEcPP enhances Ca2+ influx, activating CAMTA3 and enabling it to bind RSRE, thereby initiating the transcription of stress response genes. This dual mechanism-dismantling suppressors (HAT1, TPL, and IMPα-9) and activating CAMTA3-underscores MEcPP's central role in plastid-to-nucleus signaling. These findings emphasize MEcPP's pivotal function in dynamically regulating gene expression to maintain cellular homeostasis under environmental stress.

Conformational studies on Arabidopsis sulfurtransferase AtStr1 with spectroscopic methods.

Sulfurtransferases/rhodaneses (Str) are enzymes widely distributed in archaea, prokaryota and eukaryota, and catalyze the transfer of sulfur from a donor molecule to a thiophilic acceptor substrate. In this reaction, Str cycles between the sulfur-free and the sulfur-substituted form. Two-domain Str consist of two globular domains of nearly identical size and conformation connected by a short linker sequence, which is elongated in plant two-domain Str proteins compared to Str in other organisms. The two-domain Arabidopsis thaliana Str1 protein (At1g79230) was expressed in Escherichia coli as a mature protein, as a variant without the elongated linker sequence, and as AtStr1C332S and AtStr1C339V. The persulfuration state of the purified recombinant proteins was investigated in the presence and absence of sulfur donors by fluorescence spectroscopy. The secondary structure was analyzed by circular dichroism (CD) in the far-UV range, while overall changes in tertiary structure were determined by CD in the near-UV range. Finally, protein stability was analyzed by tryptic digestion. The elongated linker sequence is essential for correct conformation and stability, and thereby affects the catalytic activity of AtStr1. Replacement of the catalytic cysteine residue C332 leads to higher rigidity of the molecule, whereas replacement of C339 does not lead to any conformational changes, providing evidence of the direct involvement of C339 in catalysis.
