Summary: The basic features and regulatory mechanisms of seed dormancy are explained in this study. The balance between abscisic acid (ABA) and gibberellins (GAs) is crucial in determining the state of seed dormancy or germination. The antagonism between ABA and GAs is regulated by a bistable switch in the regulatory circuit. However, specific dormancy factors are required to determine the development trajectory of the seed.

Summary: Transcriptional elongation by RNAPII through chromatin is a dynamic and highly regulated step in eukaryotic gene expression. The combination of transcript elongation factors facilitates efficient transcription on nucleosomal templates. Recent advances in understanding the role of these factors in plant gene expression are discussed, including the suppression of aberrant transcript initiation and prevention of transcriptional interference with neighboring genes.

Summary: The aim of this study was to elucidate the seed-dormancy break and germination characteristics of Vaccinium oldhamii. The results showed that the seeds of V. oldhamii exhibited Nondeep physiological dormancy (Nondeep PD). Treatment with 500 ppm of GA(3) at 25/15 degrees C was able to effectively break the dormancy of V. oldhamii seeds. These findings provide convenience for further research on the species.

Summary: Seed quality and moisture content affect the germination of Cardiospermum halicacabum seeds, with seeds with water-impermeable seed coats showing different responses in different climatic zones. Seeds from DZ and WZ1 showed higher imbibition rates compared to WZ2 seeds, indicating that scarified seeds are more likely to germinate.

Summary: This study reports on the influence of testa and endosperm on seed germination of the caper shrub, as well as the effect of gibberellic acid (GA(3)) solutions in breaking seed dormancy. The best germination results were observed with seeds devoid of testa wetted with water and intact seeds wetted with a GA(3) solution. GA(3) addition increased endogenous gibberellin content and the GA/abscisic acid ratio, promoting seed germination. Germination of caper seeds involved testa cracking and endosperm piercing, with puncture force decreasing during imbibition and remaining constant until testa cracking occurred.

Summary: The study investigates the relationship between the content of phenylpropanoids in chickpea seed coats and dormancy. Significant differences in phenolic and flavonoid metabolites were found among different chickpea genotypes. Phenolic acids were generally more concentrated in the wild parental genotype and dormant recombinant inbred lines (RILs).

Summary: This review provides a revised and expanded word-formula system of whole-seed primary dormancy classification, highlighting the great diversity and complexity of primary seed dormancy at the whole-seed level. The changes include an increase in the number of named tiers in the classification hierarchy, provision of formulae for known kinds of dormancy, and the designation of new subclasses in the morphological dormancy class.

Summary: This study proposes dividing the microbial inheritance process into three stages: plant to seed, seed dormancy, and seed to seedling. It discusses the factors affecting microbiome assembly during these stages, highlights future research directions, and emphasizes the implications of microbial inheritance for fundamental science and society.

Summary: The ESX-5 type VII secretion system is a membrane-spanning protein complex crucial to the virulence of mycobacterial pathogens. The high-resolution structure of the 2.1-megadalton ESX-5 core complex reveals a dynamic, secretion-competent conformation of the pore with flexibility for accommodating targeted protein secretion, suggesting that a highly dynamic state of the pore may be a fundamental principle of bacterial secretion machineries.
