Summary: YABBY is a specific transcription factor gene family in plants that play important roles in leaf and floral organ development. In this study, seven YABBY genes were identified in the mango genome, which were classified into three subfamilies. The expression of these genes showed significant changes under biotic and abiotic stresses. Additionally, the expression of MiYABBY genes was specific to different leaves and fruits. This study provides valuable insights into the biological functions and molecular mechanisms of YABBY genes.

Summary: This study aimed to systematically analyze the YABBY genes in lotus and provide insights into their response to salt stress. Nine YABBY genes were identified in the lotus genome, distributed on six different chromosomes and named from YABBY1 to YABBY9. These genes were divided into five subgroups and were found to be involved in plant hormone signaling and abiotic stress responses. The expression of YABBY genes was regulated by ABA, fluridone, and salt treatment, and subcellular localization showed that NnYABBY4, NnYABBY5, and NnYABBY6 were localized in the cell membrane and cytoplasm. Moreover, NnYABBY4, NnYABBY5, and NnYABBY6 lacked intrinsic trans-activity. This study provides a theoretical basis and reference for the molecular breeding of lotus.

Summary: The molecular basis of orchid flower development is achieved through a specific regulatory program involving class B MADS-box AP3/DEF genes. Differential expression of four class B AP3/DEF genes determines organ identities in the orchid perianth, enriched by other MADS-box genes like AGL6 and SEP-like. The YABBY DL-like gene PeDL2 is strongly expressed in the labellum of wild-type Phalaenopsis flowers, and its involvement in labellum development is suggested by its expression pattern in peloric mutant Phalaenopsis.

Summary: Heat stress limits the growth and development of crops, including grapevine. Two heat stress transcription factors, VdHSFA2 and VvHSFA2, were identified and characterized. VdHSFA2 confers higher thermotolerance and can regulate more target genes than VvHSFA2, making it a potential candidate for molecular breeding in grape thermotolerance.

Summary: This study identifies VvibHLH93 as a new transcription factor in the PA pathway of grapes and demonstrates its role in suppressing PA accumulation through the repression of two VviLAR genes. Additionally, VvibHLH93 is also associated with other genes and transcription factors in the flavonoid pathway.

Summary: This study discovered that the transcription factor VaERF16 enhances grape resistance to B. cinerea infection and the bacteria Pseudomonas syringae DC3000. VaERF16 interacts with VaMYB306 transcription factor, leading to an up-regulation of the defense-related gene PDF1.2 and increased resistance. Elucidation of this regulatory module is of importance in enhancing grapevine resistance to B. cinerea infection.

Summary: This study identified DchYABBYs, DhuYABBYs, and DnoYABBYs from the genome databases of three Dendrobium species and found that they were unevenly distributed on different chromosomes. It was discovered that DchYABBY2 plays a crucial role in ovary and early petal development, DchYABBY5 is essential for lip development, and DchYABBY6 is crucial for early sepal formation. Additionally, DchYABBY1 primarily regulates sepals during blooming, and there is potential involvement of DchYABBY2 and DchYABBY5 in gynostemium development. This comprehensive genome-wide study provides important clues for future functional investigations and pattern analyses of YABBY genes in the Dendrobium species.

Summary: The failure of midrib formation in rice leaf blades results in the drooping leaf (dl) phenotype. A new drooping leaf mutant named dl-6 in rice was analyzed genetically. The dl-6 mutant exhibited severely folded and twisted leaves but normal flower structure. It is a nuclear recessive trait with a 3:1 Mendelian segregation ratio. The dl-6 mutant displayed abnormal main veins with undeveloped aerenchyma and vascular bundles, resulting in severe leaf drooping. Through genetic mapping, the dl-6 allele was identified on rice chromosome 3 and caused by mutations within the DL gene encoding a dysfunctional YABBY transcription factor. This mutant provides insight into the regulation of leaf midrib development and its importance in maintaining leaf structure in rice.

Summary: Understanding grapevine reproductive processes is crucial for managing yield and quality, especially in clones with contrasting seed content. Genetic analysis revealed differences between seedless variants and normal seeds, suggesting potential traceability markers for improved propagation. Meiotic anomalies likely contribute to seedlessness, with identified single nucleotide polymorphisms as possible functional candidates for the seedless phenotype.

Summary: The NAC transcription factor TwNAC01 plays a crucial role in regulating plant growth, development, and stress responses. It enhances plant stress tolerance by increasing root length, regulating leaf water content, and adjusting respiration rate. Overexpression of TwNAC01 in Arabidopsis resulted in reduced leaf water loss and longer roots, while silencing TwNAC01 in triticale led to delayed root development and increased oxidative damage under drought stress. These findings highlight the potential of TwNAC01 as a target for improving triticale and cereal crops.

Summary: In this study, a gene called VvANN1 was characterized, which was found to play a positive role in the response to drought stress. VvANN1 was induced by osmotic stress and enhanced tolerance to osmotic and drought stress in Arabidopsis thaliana. It was also discovered that VvbZIP45 can regulate VvANN1 expression by binding to its promoter region under drought stress. These findings are important for understanding the mechanisms of grapevine adaptation to drought.

Summary: In this study, it was found that there are genetic differences in the coding region of the heat stress transcription factor HSFA2 between heat sensitive and heat tolerant grape plants. The heat tolerant plants showed higher heat tolerance due to the variation in a single amino acid in the AHA1 motif. Additionally, the MBF1c gene was identified as a target gene of HSFA2, and overexpression of MBF1c enhanced thermotolerance in grape plants.

Summary: The YABBY gene family, present in all seed plants, plays crucial roles in plant growth and development, including polarity establishment, leaf and flower formation, and response to hormonal signals and environmental stress. Through identification of 364 YABBY genes in 37 Brassicaceae genomes, it was found that these genes are largely conserved across species but exhibit considerable functional divergence.
