Summary: Plant aerial development relies on meristem activity, with shoot apical meristem (SAM) formed in the embryo contributing to the main stem and axillary meristems (AMs) formed post-embryonically contributing to the branched structure. This review discusses recent findings on the de novo establishment of AMs and emphasizes the progressive process of stem cell formation, different from functional meristems.

Summary: In plant stem cells, noncell-autonomous transcription factors, such as AUXIN RESPONSE FACTOR3 (ARF3), play a crucial role in coordinating cell-cell communication. ARF3 regulates the expression of boundary-specific genes to control organ arrangement and represses cytokinin activity and WUSCHEL expression to regulate meristem activity through cell-cell communication.

Summary: Locules are the seed-bearing structure of fruits, and their number is controlled by the CLAVATA-WUSCHEL pathway. Disruption of this pathway can lead to larger floral meristems and increased locule number. A mutant allele in a CLAVATA 1 (CLV1) homolog was identified in Brassica rapa, which resulted in an increased number of locules as well as the formation of additional internal gynoecia.

Summary: The study investigated the spatial-temporal expression of six candidate genes in early developing seeds of Ginkgo biloba, revealing that the gene expression patterns are not entirely conserved between angiosperms and Ginkgo biloba. Additionally, through comparative transcriptome analyses, novel genes potentially involved in ovule development in Ginkgo biloba were identified. Furthermore, the expression analyses provided support for the synangial or neo-synangial hypotheses for the origin of the seed.

Summary: In this research, a toxin gene control system for plants based on dexamethasone (DEX) induction was constructed and utilized to successfully control the growth of tobacco axillary buds after topping. The DTA expression system under DEX induction was sensitive and efficient, indicating its potential for controlling axillary bud growth and development in tobacco. The study analyzed different DEX concentrations and application days to determine the optimal conditions for gene expression and growth control in tobacco plants.

Summary: A candidate gene Bndm1 related to determinate inflorescence was mapped to a specific region on C02 in Brassica napus. Plants with determinate inflorescence exhibited improved traits in field production and determinacy was regulated by a single recessive gene, Bndm1. Through genetic mapping and analysis, a possible candidate gene BnaC02.knu was identified, which plays an important role in determining inflorescence in B. napus. The findings of this study provide new insights for optimizing plant architecture and breeding novel canola varieties suitable for mechanized production.

Summary: CLE peptides control stem cell activity in meristems, with some CLE peptides promoting stem cells and others suppressing them. The CLV3 pathway, involving a negative feedback loop, plays a crucial role in maintaining stem cell population and regulating shoot growth and organogenesis. This paper proposes a model for the evolution of meristem zonation based on recent studies, suggesting that a stem cell limiting pathway evolved from a stem cell promoting pathway through gene duplication in angiosperms. Future genomic and developmental studies can verify this model.

Summary: Research has shown that the ESR1 gene interacts with genes related to WUS and STM, affecting their phenotypes in plant lateral organ development. The ESR2 gene can partially suppress the phenotype of the STM gene in the later nutritional stage, and this complex genetic interaction is related to the different expression patterns of ESR genes.

Summary: Distinct from animals, plants maintain organogenesis from specialized tissues called meristems throughout life. The shoot apical meristem (SAM) in the shoot apex produces all aerial organs, and cell signaling within functional domains is crucial for SAM functions. Recent studies on the WUSCHEL-CLAVATA feedback loop and polar auxin transport and signaling have expanded our understanding of SAM homeostasis and organogenesis. Furthermore, single-cell techniques have improved our knowledge of cellular functions in the shoot apex.

Summary: PtrWOX4a is a highly expressed stem vascular-cambium-specific gene in Populus, whose expression is regulated by PtrVCS2 gene encoding a zinc finger protein. PtrVCS2 binds to the PtrWOX4a promoter as part of a PtrWOX13a-PtrVCS2-PtrGCN5-1-PtrADA2b-3 protein tetramer. PtrVCS2 prevents the interaction between PtrGCN5-1 and PtrADA2b-3, leading to hypoacetylation of H3K9, H3K14 and H3K27 at the PtrWOX4a promoter and fewer cambium cell layers.

Summary: The research focuses on using root tips and young leaves from seedlings as alternative explants for plant regeneration, achieving high rates of embryogenic callus induction. Differences in callus induction rates among these explants may be closely related to the expression level of stem cell-related genes in the callus tissue.

Summary: A novel de novo missense mutation in the SP6 gene was identified, causing amelogenesis imperfecta. This mutation, located at the same nucleotide positions as a previous report but with a different insertion, resulted in a much more severe clinical phenotype. The mutant protein level was significantly decreased compared to the wild-type, despite similar mRNA levels.

Summary: Amelogenesis imperfecta (AI) is a rare genetic condition affecting tooth enamel, causing insufficient enamel quantity or altered quality. A mutation in ENAM was identified in a Caucasian family with hypoplastic AI, leading to abnormal translation and reduced protein expression. This study provides insights into how a mutation in the ENAM gene can cause hypoplastic AI while maintaining normal amino acid sequence.

Summary: In this study, a method called matrix-TE was used to comprehensively investigate the differentiation of LTR/TEs in plant genomes. The results showed that there were six LTR/TE superfamilies in Indica and Japonica rice genomes, and the divergence between the two genomes was mainly caused by Ty3/Gypsy insertion events.
