Summary: Accurate and timely knowledge of crop phenology is crucial for planning farming activities. The PolSAR technique has potential for crop phenology retrieval due to its short revisit time, all-weather monitoring, and sensitivity to vegetation structure. In this study, averaged Stokes-related parameters derived from multiple PolSAR data were explored for oilseed rape phenology identification, showing high sensitivity to oilseed rape growth stages.

Summary: In this study, differential expression of total protein in leaves of two transgenic oilseed rape lines and their non-transgenic parent plant was analyzed. Fourteen differential protein spots were identified, including eleven upregulated and three downregulated proteins, involved in photosynthesis, transporter function, metabolism, protein synthesis, and cell growth and differentiation. These changes in protein spots may be attributed to the insertion of foreign transgenes in transgenic oilseed rape, but transgenic manipulation does not necessarily cause significant changes in the proteomes of oilseed rape.

Summary: This study investigated the effects of genotype, environment, and their interaction on seed yield and breeding traits of winter oilseed rape. The results showed significant differences in yield and other traits among the tested genotypes across different years and locations. The correlation analysis indicated a strong negative relationship between seed yield and the beginning of flowering. Multivariate statistical methods were used to characterize the tested genotypes in terms of multiple traits, revealing variations between different cultivars and lines.

Summary: This study discussed the main reason for high oilseed rape loss in mechanized harvesting and proposed a 2-degree-of-freedom collision method (2-DFCM) for selecting varieties with high resistance. The results showed that 2-DFCM is more reliable, convenient for field testing, and accurately identifies pod characteristics, which is important for breeding oilseed rape varieties.

Summary: This study explores the potential to predict floral resource availability in oilseed rape varieties using routinely collected agronomic trait data. The quality of nectar is positively influenced by factors such as early vigour, winter hardiness, and stem stiffness, while pollen quantity is affected by traits like early maturation and resistance to lodging. Including modeled floral resource data in recommended varietal lists could help growers make informed decisions based on local pollinator populations.

Summary: Oilseed rape is an important oilseed crop with significance in the food and feed industries. A study on aminopeptidases during the germination process under standard and stress conditions revealed an increase in enzyme activity towards specific amino acids and the upregulation of genes encoding aminopeptidases under stress conditions caused by heavy metal ions.

Summary: This study aimed to investigate the protective mechanisms of exogenously applied melatonin (MT) on Brassica napus plants under cobalt (Co) stress. The results showed that MT could minimize oxidative damage, lipid peroxidation, and maintain membrane integrity. Additionally, MT enhanced the activity of antioxidant enzymes, regulated gene expression, and reduced Co accumulation in the roots. These findings indicated that exogenous MT improved plant morphology, photosynthetic apparatus, osmotic adjustments, and antioxidant defense systems by enhancing Co-detoxification.

Summary: This study aimed to investigate the mechanisms by which nitrogen fertilization influences clubroot disease. The results showed that clubroot infection led to an increase in SA concentration and induction of SA gene expression, while nitrogen-driven resistance was independent of SA signaling, soluble carbohydrate, and amino acid concentrations. The low-nitrogen-driven resistance was associated with transcriptional regulation of specific genes, including NRT2 and NR genes.

Summary: The study demonstrated that exogenously applied GSH can mitigate the phytotoxicity caused by Cd stress in oilseed rape plants by enhancing antioxidant defense and redox regulation, as well as rebalancing hormone levels, leading to improved Cd uptake and accumulation. This suggests that GSH can potentially be used for plant remediation in Cd-polluted soil.

Summary: This study assessed the genotypic variation of boron concentration in grains of spring barley, identifying a large genetic variation and 23 QTLs associated with grain boron concentration. The HvNIP2;2/HvLsi6 gene, encoding a potential boron-transporting membrane protein, was closely linked to a major-effect QTL. Functional studies showed that HvNIP2;2/HvLsi6 represents a functional boron channel with expression variation affecting root and shoot boron concentrations and root dry mass formation.

Summary: The study revealed that infection by Diplodia pinea induced various systemic defense responses in pine hosts, including increased levels of abscisic acid and jasmonic acid in both pine provenances. Additionally, exclusive responses such as enhanced salicylic acid and reduced indole-3-acetic acid levels were observed in the roots of both provenances, along with increased activities of anti-oxidative enzymes. Furthermore, the two pine provenances showed significant differences in their systemic responses, which did not prevent damage to non-inoculated needles but prevented damage to the roots.

Summary: This review discusses the development and mechanisms of plant roots during the process of nutrient and water foraging, with a focus on the central role of auxin in shaping root architectural traits in response to fluctuating nutrient and water availabilities. A deeper understanding and exploitation of these auxin-related mechanisms promises advances in crop breeding for higher resource efficiency.

Summary: Optimal plant development requires plants to adjust their root architecture to optimize nutrient access and acquisition. Nutrient availability and plant demand are translated into cellular signals, often involving phytohormones, to trigger developmental responses. The timing and extent of these responses depend on the overall nutritional status of the plant, which is transmitted from shoots to roots through phytohormones or other systemic signals.

Summary: This study found that apoplastic acidification induced by ammonium is associated with iron precipitation and hydrogen peroxide accumulation along the stele in root tips, indicating iron-dependent ROS formation. Through screening ammonium sensitivity in genes, PDX1.1 was identified as an ammonium-responsive gene that is upregulated in the root stele and catalyzes the de novo synthesis of vitamin B-6. Mutants of pdx1.1 exhibit hypersensitivity to ammonium, while chemical complementation or overexpression of PDX1.1 restores root elongation. The synthesis of non-phosphorylated B-6 vitamers mediated by PDX1.1 acts as a primary strategy to protect roots from ammonium-induced ROS formation.

Summary: This study compares two Brassica napus accessions with contrasting boron efficiency and reveals the differences in phytohormone metabolism and biomass formation between the two accessions. The results suggest that the superior boron efficiency in one accession is attributed to the higher accumulation of cytokinins, which helps maintain shoot meristem activity and proper leaf development under boron-deficient conditions.

Summary: In this study, a method combining fluorescence-activated cell sorting (FACS) with inductively coupled plasma mass spectrometry (ICP-MS) was developed to assess the ionome of different cell populations within Arabidopsis thaliana roots. The results showed that most elements exhibited a radial concentration gradient increasing from the rhizodermis to inner cell layers, and previously unknown ionomic changes were detected due to perturbed xylem loading processes. Additionally, a strong accumulation of manganese in trichoblasts of iron-deficient roots was identified. These findings indicate the existence of cell type-specific constraints for efficient metal sequestration in roots.

Summary: This study reveals that Arabidopsis plants use different chemical activities of coumarins - sideretin and fraxetin - to optimize iron acquisition according to environmental pH conditions. Sideretin functions as the primary ferric iron reductant under acidic conditions, while fraxetin acts as the most efficient chelator at alkaline pH.

Summary: The proposed technology targets regulatory circuits within plants transiently, allowing for customized alterations of agronomic traits. By utilizing RNA viral transfection methods, this approach is fast, versatile, and does not involve genetic modification of plant genomes. It can be used in multiple plant species for rapid fine-tuning of traits without altering the genome.
