Summary: The transcription factor AINTEGUMENTA-like6 functions as a downstream regulator of the master regulator FUSCA3 in seed dormancy and lipid metabolism. AIL6 is activated by FUS3 and has a role in modulating fatty acid compositions in seeds. Over-expression of AIL6 leads to low seed germination rates and alterations in lipid metabolism, which can be released by the della quintuple mutant.

Summary: Analysis of barley multiovary mutants mov2.g and mov1 reveals the roles of HvSL1 and HvMADS16 genes in the development of cereal florets. The study identifies the genetic determinants and conservation in stamen formation pathways among cereals while also highlighting species-specific differences. The findings provide insights into floral architecture in Triticeae and contribute to crop improvement efforts.

Summary: This study focused on the Vitis vinifera INNER NO OUTER (INO) gene as a candidate for seedless fruit production, based on an interesting case of seedless fruit production in the Annona squamosa crop species. The VviINO gene was found to play a crucial role in the formation of ovule outer integument and seed set, with similar activity and protein targets in grapevine as in Arabidopsis. The findings have potential implications for grapevine breeding.

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: Further research is needed for the development of new seedless grape cultivars. VvHB63, a Homeobox gene, plays a crucial role in fruit and seed development in grapes. The interaction between VvHB63 and VvHB06 is essential for its function, and the synergistic cooperation between VvHB63 and related proteins is important for ovule development.

Summary: This study investigates the transcriptional response of different rapeseed cultivars to heat stress and reveals the molecular mechanisms underlying the phenotypic changes during early seed development. The results suggest that the response to reactive oxygen species, seed photosynthesis, and hormonal regulation may be critical factors for heat tolerance in oilseed rape.

Summary: The developmental regulation of flower organs involves the spatio-temporal regulation of floral homeotic genes. BASIC PENTACYSTEINE genes (BPC genes) are plant-specific transcription factors that play important roles in plant development. In this study, a Class I BPC gene (CjBPC1) from Camellia japonica was characterized. It was found that CjBPC1 is highly expressed in the central whorls of flowers and overexpression of it in Arabidopsis led to severe defects in siliques and seeds. Further analysis revealed that CjBPC1 recruits the Polycomb Repression Complex to suppress the expression of genes involved in ovule and seed development.

Summary: The study shows that land transfer has a significant impact on urban development, especially market-led land transfers are more sustainable for urban economic benefits. Governments should control land prices and regulate the relationships between developers and consumers through legislation and land system reform to promote the sustainable development of land transfers.

Summary: The study investigates the evolutionary origins of seed development using the Carboniferous fossil Genomosperma, revealing significant variation in integumentary lobes of its ovules. Seeds of Genomosperma were also identified within cupules for the first time. The research suggests that the integument, nucellus, and cupule may have developed in a shoot-like manner, potentially ancestral to extant seed plant reproductive shoots.

Summary: Floral homeotic genes in angiosperms, such as OsMADS13 in rice, play a crucial role in determining ovule identity. The interaction between OsMADS13 and other genes, like those in the SEP family, may control a common set of target genes involved in ovule development. This study sheds light on the regulatory pathways in rice gynoecium development and provides insights into the role of OsMADS13 as a repressor of the carpel pathway during ovule development.

Summary: Transcription factors play important regulatory roles in different stages of embryo development, including embryonic patterning and seed maturation. Specific transcription factor families, such as WOX, HD-ZIP III, ARF, and CUC, have distinct functions in embryonic patterning, while LEC1, ABI3, FUS3, and LEC2 are considered the master regulators of seed maturation. Genes associated with these transcription factors have been identified using genomics approaches and chromatin immunoprecipitation.

Summary: In spermatophytes, proper coordination of the diploid and haploid generations is crucial for successful plant reproduction. The WOX transcription factor gene family, including STIP, plays important roles in various plant development processes. This study demonstrates the essential role of STIP in the correct patterning and curvature of the ovule in Arabidopsis thaliana. STIP is also involved in the regulation of the female germline and key ovule factors. These findings provide new insights into the genetic networks governing ovule development.

Summary: Cycadales and Ginkgoales are two of the oldest lineages of extant seed plants, making them important candidates for studying seed evolution and related genes. The ovules of these plant lineages have a massive integument, with differences in vascular bundles and ergastic substances. These differences are key in understanding the evolution of land plants.
