“…Any local increase above that baseline triggers immediate effects on structural and functional proteins, activating downstream responses. In fact, a long list of sensor proteins is known to be affected by Ca 2+ , including Ca 2+ ‐dependent protein kinases, calcineurin B‐like proteins, calmodulin and calmodulin‐like proteins (Ravi et al ., 2023). One major challenge in plant cell biology is the decoding of Ca 2+ ‐mediated signals.…”

SummaryChitin oligomers (COs) are among the most common and active fungal elicitors of plant responses. Short‐chain COs from symbiotic arbuscular mycorrhizal fungi activate accommodation responses in the host root, while long‐chain COs from pathogenic fungi are acknowledged to trigger defence responses. The modulation of intracellular calcium concentration – a common second messenger in a wide variety of plant signal transduction processes – plays a central role in both signalling pathways with distinct signature features. Nevertheless, mounting evidence suggests that plant immunity and symbiosis signalling partially overlap at multiple levels. We here elaborate on recent findings on this topic, highlighting the nonbinary nature of chitin‐based fungal signals, their perception and their interpretation through Ca2+‐mediated intracellular signals. Based on this, we propose that plant perception of symbiotic and pathogenic fungi is less clear‐cut than previously described and involves a more complex scenario in which partially overlapping and blurred signalling mechanisms act upstream of the unambiguous regulation of gene expression driving accommodation or defence responses.

“…Once inside plants, Ca plays the above-mentioned intracellular messenger role. As such, plant cells reprogram their cellular setup by triggering a network of signaling events, which start with stress perception at the cell membrane level and end with a cellular response [8,9]. Many extracellular and environmental cues (light, biotic or abiotic stress factors) elicit changes in cellular Ca levels, termed calcium signatures [10].…”

Calcium (Ca) plays a vital role as a macronutrient in the growth and development of plants. In order of decreasing solubility, Ca can be found in vegetal tissues as soluble Ca (Fraction I), bound Ca (mainly pectates, Fraction II), inorganic insoluble Ca (mainly phosphates and carbonates, Fraction III) and organic insoluble Ca or oxalate (Fraction IV). To explore the impact of Ca fertilizer application on plant growth and its allocation among different fractions, young citrus trees were fed over a complete vegetative cycle with a 44Ca labeled fertilizer (T1-Ca), while control plants (T2) received no Ca fertilizer. The results showed that plants receiving Ca exhibited significantly greater biomass. 44Ca derived from the fertilizer was localized mainly in sink organs (new flush leaves–twigs and fibrous roots). The primary fraction responsible for total Ca partitioning was Fraction II, followed by Fraction III or IV. Citrus plants, commonly found in calcareous soils, demonstrated improved growth with calcium treatments, indicating a positive link between calcium supplementation and enhanced development. The calcium supplied through the fertilizer (44Ca) was predominantly concentrated in sink organs (mainly in Ca-pectate fraction), including new flush leaves and twigs above ground, as well as fibrous roots below ground.
