Summary: BARLEY B-RECOMBINANT/BASIC PENTACYSTEINE (BBR/BPC) family members are plant-specific GAGA-motif binding factors (GAFs) controlling multiple developmental processes of growth and propagation. This study reveals the importance of BPCs in regulating growth and development by forming a meticulous repressor network. These findings provide insights into the molecular mechanisms controlling plant growth and development.

Summary: Seed size is controlled by complex molecular networks in Arabidopsis, with the MADS-domain transcription factor SEEDSTICK playing a key role in regulating it. STK acts as a maternal activator of growth in the earlier phases of seed development by positively regulating cell cycle progression via activating the expression of E2Fa.

Summary: In this study, a maize WRKY transcription factor gene, ZmWRKY70, was cloned and found to be accumulated under submergence stress in maize seedlings. ZmWRKY70 was localized in the nucleus and had transcriptional activation activity. Overexpression of ZmWRKY70 in Arabidopsis and maize increased the tolerance to submergence stress by upregulating the expression of key genes involved in anaerobic respiration. ZmWRKY70 enhanced the expression of ZmERF148 by binding to its promoter region. These findings suggest that ZmWRKY70 plays a significant role in submergence stress tolerance.

Summary: GLK1 is a key transcriptional regulator of photomorphogenesis, and, together with TCP15, it regulates the light-induced cotyledon opening and expression of related genes in plants. TCP15 forms a complex with GLK1 to coordinate the expression of cell expansion genes and genes involved in the development of the photosynthetic apparatus.

Summary: This study investigated the metabolic adjustments in plants under carbon starvation and the role of the transcription factor WRKY45. The results showed that overexpression of WRKY45 leads to early senescence and altered amino acid metabolism, and is associated with dysregulation of mitochondrial signaling and activation of alternative respiration.

Summary: In this study, the GmABR1 gene from soybean was investigated for its aluminum tolerance. The results showed that GmABR1 gene was constitutively expressed in root tip, stem, and leaf tissues, and its transcript increased significantly under aluminum stress. GmABR1 may regulate plant resistance to aluminum stress through genes related to aluminum stress response and ABA response pathways.

Summary: The SLIM1 transcription factor plays a crucial role in arsenic-induced gene expression and tolerance mechanisms. Mutant alleles in SLIM1 exhibit higher sensitivity to arsenic than cadmium, leading to increased oxidative stress and impaired sulfur assimilation. Enhanced arsenic accumulation in roots of slim1 mutants suggests altered redox status as a possible cause for their severe arsenic sensitivity.

Summary: ABI4 is a key player in the ABA signaling pathway and is involved in plant response to abiotic stress and development. ABI4 is tightly regulated both post-transcriptionally and post-translationally. Abiotic factors and plant hormones have similar effects on ABI4 transcripts and protein levels.
