Summary: The study revealed that various polymer types in the Arabidopsis seed coat provide protection against chromium (Cr3+) toxicity through different mechanisms and degrees. Suberin was identified as the main physical barrier against Cr3+ toxicity. The results also emphasized the risks associated with Cr3+ toxicity on the persistence of seeds with relatively low seed coat suberin in soils contaminated with high levels of chromium.

Summary: This study investigated the effect of seed color on the germination and growth of alfalfa under salt stress. The results showed that brown seeds had significantly lower germination and seedling performance compared to green and yellow seeds. Yellow seeds exhibited higher vigor. Factors such as water uptake rate and hormone content may have contributed to the differences in stress resistance among seed colors.

Summary: The domestication process of legume seeds has resulted in altered dormancy patterns, leading to faster and more uniform germination compared to wild progenitors. By studying the physiological and anatomical aspects of seed dormancy, significant differences were observed between cultivated chickpeas and wild progenitors, providing insights into potential molecular mechanisms of seed dormancy in chickpeas.

Summary: The sunflower seed dormancy is regulated by the interaction between the one-layered endosperm, seed coat, and embryo, and the levels of ABA, JA, and IAA in these tissues. The release of dormancy is associated with increased ABA and JA levels in the seed coat and endosperm, but decreased levels in the embryo. The anatomy of the seed coat and one-layered endosperm showed no significant differences between lines. The findings highlight the importance of hormone metabolism and tissue interactions in the release of sunflower seed dormancy.

Summary: The study found that under water stress conditions, brown-seeded families had significantly higher heritability and genetic advance for seed yield compared to yellow-seeded families. Additionally, while yellow-seeded families had higher SDG content in non-stress environments, brown-seeded families showed an increase in SDG content under water stress conditions.

Summary: Seed germination and subsequent seedling growth of alfalfa are not significantly affected by vanadium concentrations up to 10 mg L-1 V, however, root vitality and elongation are inhibited at concentrations of 0.5 mg L-1 V or higher. Accumulation of vanadium in the testa is beneficial for alleviating its toxicity to seed germination, while leaf proline content significantly increases at concentrations of 0.5 mg L-1 V or higher. Alfalfa shows potential for phytoremediation in vanadium-contaminated environments within determined thresholds.

Summary: Flavonoids are polyphenolic compounds that color flowers, fruits, and seeds. The regulation of flavonoid biosynthesis is controlled by MYB-bHLH-WD40 transcription factor complexes. This study identified and characterized the sorghum bHLH protein SbTT8, which partially rescues the seed color and dormancy in Arabidopsis tt8 mutants. The difference in size and DNA-recognition motif between SbTT8 and AtTT8 likely affects their interaction with target DNA.

Summary: The study revealed that the effects of treatments on seed dormancy breaking in Agrimonia eupatoria L. varied depending on the method and seed coat state. In uncoated seeds, 0.2% potassium nitrate and 100 mg L-1 gibberellic acid were found to be the most effective treatments, leading to improved seed germination and growth parameters.

Summary: This study aims to produce high-quality planting materials for Bauhinia retusa and Bauhinia variegata in nurseries for afforestation programs. The results show that a constant temperature of 25℃ is most suitable for the seed germination of both species, and polybags are the most suitable storage containers for Bauhinia seeds. Yellow color and larger seeds are preferred for both species, with horizontal sowing for B. retusa and upright sowing for B. variegata resulting in the highest seedling emergence and growth.

Summary: Certain substances called germination inhibitors can inhibit the germination of seeds. They can be classified as germination destructors or germination retarders, with the former causing harm to the seed and the latter being closely related to seed dormancy. These inhibitors have important applications in seed preservation and herbicide use.

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 found that wild or less domesticated Capsicum species showed higher germination rates after accelerated seed aging treatments compared to more domesticated varieties. Variability was observed in the expression of genes involved in response to seed deterioration, with faster mobilization of seed storage proteins in aging-resistant genotypes. Lignin content in the seed coat was positively correlated with seed viability.

Summary: The KNOX gene plays crucial roles in plant development, and this study identified 19 KNOX gene members in kiwifruit. One of the genes, AcKNOX11, is selectively expressed in flower buds and shoots, and its expression can be induced by ABA and melatonin. Functional analysis revealed that AcKNOX11 delays flowering, reduces plant height, alters leaf shape, and inhibits seed germination through ABA-melatonin interaction.

Summary: This study revealed that nitrogen deficiency can lead to increased production of reactive oxygen species (ROS) and methylglyoxal (MG), but also enhances the ability of leaves and roots to detoxify these molecules. The effects of nitrogen deficiency on ROS and MG generation and their detoxification systems were found to be different in leaves and roots, with roots being more affected.

Summary: Bagging is a crucial cultivation measure that affects the quality of peach fruit by regulating exposure to light. This study investigated the effects of bagging on the content of phenolic compounds in peach fruit and identified the most sensitive compounds to bagging treatment. The study also explored the regulatory role of bagging on phenolic synthetic-related genes. The results showed that bagging affected the accumulation of different phenolics in different peach cultivars and light intensity played a significant role in the accumulation of anthocyanins and other phenolic substances in peach fruit. Additionally, the expression of structural genes and transcription factors related to phenolic synthesis was regulated by bagging and light conditions. These findings provide a foundation for understanding the regulation mechanism of light on the synthesis of phenolic compounds in peach fruit.

Summary: This study investigates the agroclimatic requirements of Prunus species cultivars growing in warm areas using Partial Least Squares regression. The findings reveal that the chilling and heat requirements of the cultivars appear discontinuous, with overlaps or transition periods between the two phases. The warm mean temperatures occurring during the chilling period are the main determinant of the flowering of the studied cultivars.

Summary: This study used Sentinel-2 satellite images to estimate biophysical and biochemical parameters of spinach crops and found that canopy-level parameters were estimated more accurately. The estimation of the canopy-scale parameter AGB using MCARI showed the highest accuracy, while the estimation of the leaf-scale parameter LCC using NDWI showed the lowest accuracy. At the field scale, the validation results for AGB estimation using SR were the best.

Summary: This study investigated the effects of water stress on cocoa trees and found that they are highly sensitive to water stress, with different genotypes exhibiting varied responses. Potassium application did not mitigate the negative effects of water stress. There was significant variation among genotypes in terms of leaf and crown traits, and positive interactions between genotype and irrigation were observed. These findings provide insights into the acclimation strategies of cocoa trees and can be useful for selecting drought-tolerant genotypes.
