Summary: To optimize the harvesting time of Sapium sebiferum seeds for biodiesel production, the variation of chemical constituents in the seed oil harvested during different days was tracked. It was found that the unsaturated fatty acids in the seed oil increased during the harvesting time, while the external wax progressively oxidized to formic acid. Considering the quality and total weight of lipids, it is suggested that the optimal harvesting time for S. sebiferum seeds is in early November, when the fruits crack open and the seeds are initially exposed to air.

Summary: The study found that the treatment with 3% straw biochar was the most effective soil conditioner for cultivating S. sebiferum seedlings, leading to improvements in seedling height, ground diameter, and biomass. Biochar not only improved root morphology by developing primary lateral roots, but also enhanced nutrient assimilation and stem growth, contributing to the growth and survival rate of S. sebiferum seedlings during transplanting and reforestation.

Summary: This study found that the rhizosphere bacterial diversity of Sapium sebiferum trees grown in the coastal region is relatively higher compared to nursery-grown trees. Certain rare bacterial groups were largely absent in the rhizosphere soils of nursery-grown trees. The study also identified some bacterial groups as biomarkers for the coastal environment. These findings suggest that rhizosphere microbial interactions may promote the adaptability of S. sebiferum trees in the coastal environment.

Summary: The transcription factor SsMYB1 plays a key role in regulating anthocyanin biosynthesis and leaf coloration in Chinese tallow. SsbHLH1 acts as a co-regulator with SsMYB1 to modulate anthocyanin pathway, and their combined effect is further enhanced by binding to the promoters of SsDFR1 and SsANS.

Summary: Research shows that DOG1 could systematically control the expression of phytohormone-related genes, resulting in significant changes in the endogenous signal intensity of ABA, IAA, GA, BR, and CK, which in turn affect seed dormancy.

Summary: Pre-harvest sprouting (PHS) is a detrimental trait in cereal production, and the regulatory mechanism involves the OsVP1 and Sdr4 genes. OsVP1 mutant showed increased PHS compared to the wild type, and activated the expression of Sdr4 by binding to its promoter. Both OsVP1 and Sdr4 mutants were insensitive to exogenous ABA and utilized the ABA signaling pathway in regulating seed dormancy, shedding light on strategies to prevent PHS in rice.

Summary: Seed dormancy and longevity play important roles in crop production, but their relationship is still unclear. Some studies suggest a positive correlation between seed dormancy and longevity, while increasing evidence highlights a negative relationship, mainly influenced by phytohormones.

Summary: Seed dormancy is an important adaptive trait that prevents germination at inappropriate times. FIP1, a component involved in pre-mRNA processing, is found to play a crucial role in seed dormancy and germination in Arabidopsis. Knockout of FIP1 reduces seed dormancy and renders the mutant insensitive to exogenous ABA during germination.

Summary: Seed dormancy is a critical agricultural trait influenced by complex genetic and environmental factors. Through field screening of a rice mutant library, a pre-harvest sprouting (PHS) mutant dor1 was identified, which had a single insertion of the Ds element in the OsDOR1 gene. The OsDOR1 protein was found to interact with the GA receptor protein OsGID1, and hindered the formation of the OsGID1-OsSLR1 complex, thus leading to reduced GA signaling and enhanced seed dormancy.

Summary: Drought stress affects crop productivity and food shortages. The plant hormone abscisic acid (ABA) plays a crucial role in regulating drought tolerance and seed germination. The miR159-MYB33-ABI5 module has been identified as a key player in the regulation of drought response and seed germination in plants.

Summary: The study revealed that overexpression of SsKAI2, a receptor gene for karrikins, enhanced plant cold tolerance by increasing levels of proline, soluble sugars, and soluble protein, as well as upregulating cold-stress-acclimation-related genes and antioxidant enzymes. The results suggest a potential interaction between SsKAI2 and ABA signaling pathways, providing new insights into the role of karrikins in regulating cold stress adaptation.

Summary: Temperature variation during seed set plays a crucial role in regulating seed dormancy and growth vigor through affecting ABA dynamics and catabolism in individual seed tissues. Warm temperature during seed maturation promotes seed germination, while cold-matured seeds continue to store maturation-associated transcripts like DOG1 due to effects on mRNA degradation before quiescence. Temperature also impacts the divergent relationships between temperature and mRNA breakdown, as well as between temperature, seed moisture, and the glass transition.

Summary: DOF6 induces MLP329 expression to enhance primary seed dormancy in Arabidopsis via a high ABA/GA ratio, and this is suppressed by RGL2 in a negative-feedback mechanism to regulate dormancy. MLP329 probably enhances the endogenous ABA/GA ratio to positively regulate primary seed dormancy.

Summary: The study found that Karrikinolide (KAR(1)) can promote seed germination in wheat under salt stress by regulating hormone biosynthesis genes and inhibiting abscisic acid biosynthesis and signaling genes. Additionally, KAR(1) can improve root and shoot growth in wheat seedlings, as well as maintaining redox and K+/Na+ balance.
