Summary: The transition from seed to seedling is a crucial stage in the life cycle of plants, involving tissue hydration, mobilization of nutrients, and activation of metabolic activity in seeds. This process requires extensive reprogramming of genetic, epigenetic, and hormonal switches, leading to the activation of vegetative growth genes and silencing of seed maturation genes.

Summary: This study identified 61 B3 genes in the castor bean genome, classified into five subfamilies. The RcABI3/VP1 subfamily genes were found to be significantly up-regulated in the middle and later stages of seed development, potentially associated with the accumulation of storage oils. The seed-specific transcription factor RcLEC2 was shown to directly regulate the transcription of RcOleosin2, suggesting its involvement in the regulation of storage material accumulation.

Summary: This study analyzed the variation of linker histone GH1 in castor bean and its expression profiles in different tissues and stress conditions. The results revealed the high conservation of the GH1 domain and divergence of the N- and C-terminal domains between species. Additionally, the mutation rate of linker histone genes was found to be similar to that of oil-related genes. Furthermore, two linker histones were identified to potentially be under balancing selection.

Summary: The study identified 1162 seed-specific genes in castor bean and found 32,567 DNA methylation valleys (DMVs) which are highly hypomethylated across plant species and have the potential to activate transcription. Further analysis showed that DMVs can act as cis-regulatory elements, like enhancers, to regulate seed-specific gene expression, highlighting the importance of epigenetic regulators in seed development in castor bean and other crops.

Summary: This exploratory study investigated the effect of biosynthesized TiO(2)NPs using seed extract of Cuminum cyminum on seed germination and germination indices of Mung bean (Vigna radiata). The results showed a significant enhancement in germination indices values for Vigna radiata with effective treatment of TiO(2)NPs compared to non-treated seeds.

Summary: The transition from seed to seedling is a crucial step in the plant life cycle. In this study, the authors investigated the changes in water and oxidative status, as well as gene expression, during this transition in Pisum sativum seeds. They found that the accumulation of ROS and the shift in water and oxidative status were correlated with the loss of desiccation tolerance. RNA sequencing analysis revealed differentially expressed genes related to metabolism, photosynthesis, cell wall biosynthesis, redox status, and stress responses. The findings suggest that specific genes, such as LTI65, LTP4, and HVA22E, may play a crucial role in the desiccation tolerance loss during the transition.

Summary: The broad bean weevil (Bruchus rufimanus Boh.) is an economically important insect pest that damages the broad bean crop by burrowing into the seed and feeding on the endosperm or embryo, leading to reduced germination and seedling growth. This study conducted from 2018 to 2020 investigated the impact of seed damage by B. rufimanus on seed quality, germination rate, seedling growth, and the incidence of seed-borne fungal pathogens. The results showed that seed damage by B. rufimanus was associated with increased fungal contamination and decreased germination rate. Various fungal genera, including Fusarium spp., Alternaria spp., Aspergillus spp., Penicillium spp., Cladosporium spp., Mucor spp., and Botrytis spp., were identified. Cladosporium spp. was the most common genus.

Summary: This study identified the physiological mechanism of physical seed dormancy in common bean and identified a candidate allele causing variation in this trait. The results suggest that a 5-bp insertion in an ortholog of pectin acetylesterase 8 is likely a major causative mutation underlying the loss of seed dormancy during domestication. Confirmation through transgenic approaches may be necessary to further validate these findings.

Summary: In this study, the DRM1 gene was isolated from embryos of Amomum tsaoko, and its subcellular localization was determined to be mainly nucleus and cytoplasm. Expression analysis showed that DRM1 had the highest transcript level in dormant seeds and short-term stratification, and it responded strongly to hormone and abiotic stress. Ectopic expression of DRM1 in Arabidopsis delayed seed germination and enhanced tolerance to heat stress by enhancing antioxidative capacities and regulating stress-associated genes.

Summary: This study investigated the germination of seven dwarf hybrid genotypes of castor seeds at different temperatures. The results showed that 25°C and 32°C were the optimal temperatures for germination, with a germination rate of 82.81%. 8°C, 12°C, and 40°C had negative effects on germination, while 16°C resulted in good results. Overall, the dwarf hybrids performed better at high temperatures, while the 'Local' genotype performed best at lower temperatures and could be used for early spring sowings.

Summary: In this study, the researchers identified a previously unknown transcriptional regulatory mechanism by which ABA inhibits seed germination and seedling establishment. They found that the interaction between ABI5 and FLZ13 leads to downregulation of ABA-repressed and growth-related genes, resulting in the inhibition of plant growth.

Summary: This study investigated the effects of the ROS scavenger DMTU on maize seed germination and found that DMTU dose-dependently inhibited germination rate and radicle growth. Histochemical analyses showed that DMTU eliminated H2O2 accumulation in the radicle sheaths and radicles. The activity of antioxidant enzyme and the expression of antioxidant enzyme-related genes were reduced in maize seeds cultured with DMTU.

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: Genomic imprinting plays a significant role in the endosperm development, storage compound accumulation, and seed germination in castor bean. The study reveals that DNA methylation has a limited role in controlling genomic imprinting, while histone modifications play a more significant role in regulating the expression of most imprinted genes.

Summary: This study sheds light on the domestication and genome evolution of castor bean by performing de novo chromosome-level genome assembly of its wild progenitor and analyzing worldwide accessions. Important candidate genes associated with plant architecture and seed size were identified through genome-wide association study and quantitative trait locus analysis. This provides valuable insights for genomics-based breeding of castor bean and potentially other tree-like crops in the future.
