“…In the context of climate change associated with world population growth, the double challenge of maintaining or improving yield as well as nutritional quality [ 6 ], including the mineral content of the harvested products, requires a greater understanding of plant responses to biotic stresses. This is particularly true for Brassica napus, a cultivated species with a high requirement in terms of fertilization [ 67 , 68 ] and whose seed quality may be impaired by deficiencies [ 69 , 70 , 71 ], heat stress [ 72 , 73 ], elevated CO 2 [ 74 ], or drought [ 75 ]. While the effects of water stress on morphological, physiological, metabolomics, and molecular traits have been widely documented [ 14 , 18 , 19 , 20 ], little attention has been focused on its effects on mineral nutrition.…”

While it is generally acknowledged that drought is one of the main abiotic factors affecting plant growth, how mineral nutrition is specifically and negatively affected by water deficit has received very little attention, other than being analyzed as a consequence of reduced growth. Therefore, Brassica napus plants were subjected to a gradual onset of water deficits (mild, severe, or severe extended), and leaves were analyzed at the ionomic, transcriptomic and metabolic levels. The number of Differentially Expressed Genes (DEGs) and of the most differentially accumulated metabolites increased from mild (525 DEGs, 57 metabolites) to severe (5454 DEGs, 78 metabolites) and severe extended (9346 DEGs, 95 metabolites) water deficit. Gene ontology enrichment analysis of the 11,747 DEGs identified revealed that ion transport was one of the most significant processes affected, even under mild water deficit, and this was also confirmed by the shift in ionomic composition (mostly micronutrients with a strong decrease in Mo, Fe, Zn, and Mn in leaves) that occurred well before growth reduction. The metabolomic data and most of the transcriptomic data suggested that well-known early leaf responses to drought such as phytohormone metabolism (ABA and JA), proline accumulation, and oxidative stress defense were induced later than repression of genes related to nutrient transport.

“…Thus, each hydroponic pot contained one individual for rapeseed and four individuals for camelina, as with soil pots. For rapeseed, fractions of N and S were provided weekly to cover the full requirements of N and S fertilizers that matched the conventional recommendations for field‐grown rapeseed plants, as calculated in Magno Massuia de Almeida et al (2021) for pot experiments. Prior to their transfer, the substrate around the roots was carefully removed to limit mechanical root injuries, according to the soil‐hydroponic‐hybrid method described in Oburger & Jones (2018).…”

“…Indeed, the increase in temperature negatively impacts the yield of aboveground plant parts and the leaf biomass in particular (Wahid et al, 2007; Allakhverdiev et al, 2008). In Brassicaceae, especially in winter rapeseed ( Brassica napus L.), high‐temperature events at the reproductive stages impair pollination, seed development and filling, leading eventually to seed yield penalties and lower seed quality (Brunel‐Muguet et al, 2015; Magno Massuia de Almeida et al, 2021; Kourani et al, 2022). The vegetative parts of rapeseed plants are also impacted by heat stress as a consequence of impairment of the photosynthetic activity and leaf development (Dikšaitytė et al, 2019; Kourani et al, 2022).…”

Root exudation is involved in the recruitment of beneficial microorganisms by trophic relationships and/or signalling pathways. Among beneficial microorganisms, Plant Growth‐Promoting Rhizobacteria (PGPR) are known to improve plant growth and stress resistance. These interactions are of particular importance for species that do not interact with mycorrhizal fungi, such as rapeseed (Brassica napus L.) and camelina (Camelina sativa (L.) Crantz). However, heat stress is known to have a quantitative and qualitative impact on root exudation and could affect the interactions between plants and PGPR. We aimed to analyse the effects of PGPR inoculation on root morphology and exudation in rapeseed and camelina at the reproductive stage. The modulation of the effects of these interactions under heat stress was also investigated. The plants were inoculated twice at the reproductive stage with two different Pseudomonas species and were exposed to heat stress after the second inoculation. In non‐stressing conditions, after bacterial inoculation, rapeseed and camelina exhibited two contrasting behaviours in C root allocation. While rapeseed plants seemed to suffer from the interactions with the bacteria, camelina plants appeared to control the relationship with the PGPR by modifying the composition of their root exudates. Under heat stress, the plant‐PGPR interaction was unbalanced for rapeseed, for which the C allocation strategy is mainly driven by the C cost from the bacteria. Alternatively, camelina plants prioritized C allocation for their own above‐ground development. This work opens up new perspectives for understanding plant‐PGPR interactions, especially in an abiotic stress context.

Background. The processes occurring in plants and their seeds under stress, as well as the defense mechanisms used by plants under stress, are poorly understood, which makes it impossible to use them to increase yields. Purpose. Review and analysis of scientific publications, devoted to the phenomenon of stress memory acquired by plants as a result of physical stressors on their seeds and possible applications of this phenomenon in plant growing and crop breeding. Materials and methods. A selection and systematic review of scientific articles on the research topic for the period 2016-2023 was performed. The study consisted of the following steps: research literature search, evaluation and selection, data synthesis and analysis. Results. The use of hormetic effects of physical agents to stimulate seed germination of crops is effective. Responses to abiotic stresses could be 'trained' by priming so that the plant becomes better able to cope with later stress. Evidence of short-term and transgenerational memory formation following plant priming has been obtained. An epigenetic mechanism for the formation of long-term stress memory in plants as a result of a physical eustressor has been identified. The eustressor induces specific epigenetic marks associated with environmental adaptation, forming a new stress-resistant plant phenotype. Physical eustressors have the potential to impart stress tolerance to crops to enhance phenotypic characteristics to prevent yield losses. Conclusion. Seed treatment with physical stressors builds plant tolerance and memory to abiotic stresses, but scientific evidence on this issue is incomplete and sketchy. The understanding and application of stress memory for breeding purposes is currently limited, but it has great potential for the development of new crop varieties.
