“…Moreover, the Arabidopsis GRAS‐type SCL28 transcription factor has been recently identified as controlling gene expression dynamics in the mitotic cell cycle [127]. Similarly, three AP2 genes have been upregulated in Arabidopsis during the G1 phase of the cell cycle [128].…”

Proteomics as a tool to decipher plant responses in arbuscular mycorrhizal interactions: a meta‐analysis

et al. 2023

The beneficial symbiosis between plants and arbuscular mycorrhizal (AM) fungi leads to a deep reprogramming of plant metabolism, involving the regulation of several molecular mechanisms, many of which are poorly characterized. In this regard, proteomics is a powerful tool to explore changes related to plant–microbe interactions. This study provides a comprehensive proteomic meta‐analysis conducted on AM‐modulated proteins at local (roots) and systemic (shoots/leaves) level. The analysis was implemented by an in‐depth study of root membrane‐associated proteins and by a comparison with a transcriptome meta‐analysis. A total of 4262 differentially abundant proteins were retrieved and, to identify the most relevant AM‐regulated processes, a range of bioinformatic studies were conducted, including functional enrichment and protein‐protein interaction network analysis. In addition to several protein transporters which are present in higher amounts in AM plants, and which are expected due to the well‐known enhancement of AM‐induced mineral uptake, our analysis revealed some novel traits. We detected a massive systemic reprogramming of translation with a central role played by the ribosomal translational apparatus. On one hand, these new protein‐synthesis efforts well support the root cellular re‐organization required by the fungal penetration, and on the other they have a systemic impact on primary metabolism.

“…TFs involved in cell cycle regulation/or stress response belong to AP2/EREBP, bZIP, C2H2, C3H, MYB, bHLH, HD‐ZIP, WRKY, NAC, MADS‐box, LOB, DOF, HB, GATA, HSF, YABBY, ABI3/VP1, and other TF families. The most overrepresented TFs in plants are members of the AP2/EREBP, C2H2, MYB, WRKY, and bHLH families (Dehghan Nayeri, 2014). The role of MYBs in trichome formation was reported by Zhou et al.…”

Transcriptome differential display of a drought‐tolerant early flowering spineless mutant of safflower (Carthamus tinctorius) and identification of candidate genes

One of the best candidates to face the increasing environmental stresses is safflower (Carthamus tinctorius L.) with natural tolerance to multiple abiotic stresses including drought. In the present study, transcriptome profile of a spineless drought-tolerant mutant of safflower with early flowering was compared to its spiny wild type. In differential RNA-Seq analyses more than 400 differentially expressed genes (DEGs) were identified in spineless drought-tolerant mutant. The expression of 8 top DEGs, mostly related to the contrasting traits, was confirmed by real-time quantitative reverse transcription PCR. Transcription factors (TFs) followed by protein kinases had the highest frequency among the identified DEGs. TF families involved in the regulation of cell cycle, development, and environmental responses were prevalent in DEGs of spineless drought-tolerant mutant, including NAC, bHLH, MYB, HD-ZIP, and ERF. Three Kyoto Encyclopedia of Genes and Genomes pathways with direct or indirect role in cell/tissue development and metabolic processes were enriched for DEGs. Our results suggest that phenotypic differences between the two contrasting genotypes can be governed via regulation of hormone signal transduction/or cell cycle and stress-related pathways. Several candidate genes for spine formation, early flowering, and drought tolerance were introduced, important instances are ZHD8 and TBL21 (candidates for spininess), three novel transcripts, respectively, encoding a CCT type protein, a MADS-box TF and a CCA1 (candidates for early flowering), and CAT2, ZAT10, and CAMTA (candidates for drought response). These findings facilitate the isolation of key genes controlling drought-tolerance, spininess, and early flowering in safflower and can be applied for developing value-added varieties through genome-based breeding programs.

“…However, in most case, we found that the expression level of genes related to cell mitosis is not affected by PMO application. This might be attributed to two reasons: 1) most of cell mitosis genes are constitutively expressed [58] and 2) PMO might affect these genes at the post transcription level which is of interest for future studies. Overall, our results suggest that PMO could be a good candidate to promote cell mitosis activities, especially under drought stress.…”

Poly (acrylic) acid coated Mn3O4 nanoparticles (PAA@Mn3O4 nanoparticles (PMO, 11.02 nm, −28.93 mV)) are synthesized to investigate whether they can help to improve maize drought tolerance and the relevant mechanisms behind this. In planta experimental results show that under drought (15% PEG 6000, polyethylene glycol, mimicking drought stress, 96 h), compared with the control plants, 500 mg L−1 PMO (root application, 96 h) improves maize drought tolerance, showing an increase of root length (21.6%), shoot length (21.2%), fresh weight (7.8%) and total protein (67.2%) content. In addition, PMO significantly decreases the malondialdehyde (MDA) content by 74.7% in maize under drought, compared with the control group. Further, PMO treated maize root apex shows significantly increased mitotic index (MI, 35.5%), and decreased hydrogen peroxide (40.9%). Compared with the control under drought (15% PEG, 96 h), thr root apex of maize plants treated with PMO (500 mg L−1, root application, 96 h) have significantly lower level of H2O2. Overall, the results show that PMO can alleviate drought‐inhibited cell mitosis activities via maintaining ROS (reactive oxygen species) homeostasis. In this study, it is not only shown that PMO can be a good nano‐regulator candidate to improve maize drought tolerance, but also that PMO has potential to modulate plant cell mitosis activities.
