Seed Germination and Physiology

Climate and seed weight drive intraspecific variation in seed longevity in storage

The paper investigates intraspecific variation in seed longevity in storage, finding significant variation among accessions and linking it to climate and seed weight.

Gibberellin enhances germination of Nolana mollis and Heliotropium pycnophyllum seeds

This study shows that gibberellin significantly enhances germination of Nolana mollis and Heliotropium pycnophyllum seeds, while other treatments had no significant effect.

The paternally derived genome opposes seed dormancy induction by the mother plant in Arabidopsis

The paper shows the paternal genome reduces seed dormancy in Arabidopsis by countering maternal siRNAs through RNA Polymerase IV-dependent RNAs.

NPF4.1 imports embryo-derived GA4 to the endosperm to promote seed germination

The paper identifies NPF4.1 as a GA transporter in the endosperm that facilitates embryo-derived GA4 import to promote seed germination.

Aging and Germination of Long-term Stored Seeds: Can MicroRNAs Unlock the Secrets?

The paper analyzes miRNA expression in seeds with varying viability during germination, identifying key miRNAs and their roles in developmental processes and RNA regulation.

Robotic Imaging and Machine Learning Analysis of Seed Germination: Dissecting the Influence of ABA and DOG1 on Germination Uniformity

The paper introduces SPENCER, a high-throughput phenotyping platform for seed germination analysis, and investigates the roles of DOG1 and ABA in germination uniformity and dormancy in Arabidopsis.

A genome-wide survey of DNA methylation in Panax notoginseng reveals CHH hyper-methylation regulates the after-ripening and dormancy of recalcitrant seeds

This study identifies CHH hyper-methylation as a key regulator of after-ripening and dormancy in recalcitrant MPD-typed seeds of Panax notoginseng.

Gasotransmitter H2S accelerates seed germination via activating AOX mediated cyanide-resistant respiration pathway

This study shows H2S accelerates seed germination by activating AOX-mediated cyanide-resistant respiration through both transcriptional and post-translational mechanisms.

A histone deacetylase complex establishes a transgenerationally inherited maternal epigenetic state controlling progeny seed dormancy

The paper shows that the VEL3 gene in Arabidopsis establishes an epigenetic state in the endosperm that controls seed dormancy in progeny across generations.

Photosynthesis and antioxidant metabolism modulate the low-temperature resistance of seed germination in maize

The study identifies that damage to photosynthesis and total antioxidant capacity, particularly SOD activity, determines low-temperature resistance in maize seed germination.

Interplay between positive and negative regulation by B3-type transcription factors is critical for the accurate expression of the ABA INSENSITIVE 4 gene.

The paper identifies a regulatory circuit involving LEC2, ABI3, and HSI/VAL proteins that controls ABI4 gene expression through RY cis-acting motifs and chromatin structure in plants.

Regulation of DNA (de)methylation positively impacts seed germination during seed development under heat stress

This study shows that DNA (de)methylation regulates seed germination under heat stress by affecting gene expression and methylation patterns in Arabidopsis.

The genomic and transcriptomic foundations of viviparous seed development in mangroves

This study identifies genetic and transcriptomic changes associated with vivipary in mangroves, highlighting the loss of the DOG1 gene and altered hormone pathways.

HSI2/VAL1 and HSL1/VAL2 function redundantly to regulate seed dormancy by controlling DOG1 expression in Arabidopsis

This study identifies HSI2/VAL1 and HSL1/VAL2 as redundant repressors of DOG1 expression in Arabidopsis, regulating seed dormancy through chromatin modification and dimerization.

Transcriptome and translatome profiling and translational network analysis during seed maturation reveals conserved transcriptional and distinct translational regulatory patterns

The paper profiles transcriptome and translatome during seed maturation, identifies translational regulatory patterns, and constructs a network to uncover gene regulation and function.
