Summary: Temperature and water availability are important factors influencing seed germination and seedling development in maize. This study determined the optimal temperature, water supply, and planting density for maize seeds by manipulating factors such as temperature, water levels, and seed size. The results showed that 20 degrees C was the ideal temperature, and water requirements were associated with seed size. Priming seeds with an antifungal solution improved seedling development.

Summary: Maize, a major crop in Africa, is threatened by the parasitic witchweed Striga. Researchers have discovered two new strigolactones, zealactol and zealactonoic acid, which have weaker germination-inducing effects on Striga compared to the major strigolactone, zealactone. They also identified a key enzyme, ZmCYP706C37, in the maize strigolactone biosynthetic pathway, and reducing its activity, along with two others, can change strigolactone composition and reduce Striga germination and infection.

Summary: Chilling injury is a serious threat to seed emergence of spring-sowing maize in China. In this study, QTL analysis and RNA-Seq technology were used to identify key genes controlling low-temperature germination in maize. Several candidate genes related to low-temperature tolerance were discovered, providing a theoretical basis for marker-assisted breeding and understanding the molecular mechanism of low-temperature germination tolerance in maize.

Summary: The study revealed that many transporters and transcription factors were upregulated in maize vivipary mutants, playing important roles in seed germination. Genes related to abscisic acid and gibberellin biosynthesis and signaling showed a uniform expression pattern. Metabolomics analysis identified unique metabolites, pathways, and gene networks affected by each individual mutation.

Summary: The study reveals the specific roles of sugars in plant responses to low-oxygen conditions, impacting gene expression, maintenance of endogenous sugar levels, and modulation of co-expression networks. Sugar supply can affect the speed and magnitude of gene induction, as well as alter the profiles of hypoxia-responsive genes carrying G4 motifs.

Summary: This study analyzed the morpho-physiological and molecular responses of maize seedlings exposed to different types and sizes of microplastics, revealing the detrimental effects on cell membrane stability, photosynthetic pigments, and photosynthetic capacity. Larger particles of microplastics were found to result in better cell restoration under microplastics-induced stress.

Summary: This study reveals the transcriptional landscape of sugar transport and utilization in maize grains through data mining, histological, and functional analysis. The findings suggest that drought represses the expression of genes involved in exporting sucrose, but enhances the expression of genes for uptake of extracellular sugars.

Summary: This study investigated the effect of varying levels of calcareousness on seed germination and seedling growth of maize hybrids, categorizing them into tolerant and susceptible genotypes. Different concentrations of CaCO3 were found to have a detrimental effect on all maize hybrids, with some genotypes showing higher tolerance to calcareousness and better seedling growth and establishment, while others were more sensitive to CaCO3 stress.

Summary: This study investigated the effects of silicon on maize seed germination and seedling growth, finding that a concentration of 15 g.L-1 significantly stimulated seed germination and promoted seedling growth. Silicon treatment also increased chlorophyll content, osmotic material accumulation, and antioxidant defense system activity, while reducing membrane system damage, reactive oxygen species contents, and stomatal aperture. These results suggest that silicon can enhance maize growth and yield, providing a solid foundation for future crop production.

Summary: This study found that cold-tolerant maize varieties have higher germination rates and growth potential under low temperature conditions, with lower hydrogen peroxide content and higher activity of enzymes related to AsA-GSH recycling. Transcription profile analysis revealed increased expression of ZmVTC2 gene in cold-tolerant varieties, suggesting coordinated improvement of AsA biosynthesis and AsA-GSH recycling can increase total antioxidant capacity to alleviate oxidative stress during maize seed germination under low temperature.

Summary: In this study, the involvement of two maize B-type Cyclins in cell proliferation during seed germination, under the stimulus of sucrose and glucose, was evaluated. It was found that CycB1;2 plays a key role in promoting cell proliferation by interacting with a specific CDKB isoform partner and changing its cellular localization to nuclei in response to glucose, which acts as a triggering signal.
