Exogenous Calcium Alleviates Nocturnal Chilling-Induced Feedback Inhibition of Photosynthesis by Improving Sink Demand in Peanut (Arachis hypogaea)

“…The accumulation of major photoassimilates (soluble sugars and starch) in leaves is critical for balancing photosynthate production and sugar consumption for tissue growth and development. A coordinated mutual relationship exists among plant growth/sink utilization and photosynthesis, rather than a simple one-way dependence of growth on photosynthesis (Adams et al, 2013;Lambers and Oliveira, 2019). Carbohydrate synthesis occurs in photosynthesizing leaves (sources) to provide substrates for plant growth (e.g., leaf expansion, stem, and root development) and maintain non-photosynthetic plant tissues (sinks; Cohu et al, 2014;Lambers and Oliveira, 2019).…”

Our findings suggest that nocturnal chilling stress directly inhibits peanut growth and nonstructural carbohydrate translocation from source to sink, resulting in a…”

“…Arachis hypogaea , peanut or groundnut, is a grain legume crop with high nutritional value that is primarily grown in tropical and subtropical regions (annual production ∼46 million tons). It originates from tropical South America and provides a vital global source of vegetable oil and protein ( Prasad et al, 2003 ; Bertioli et al, 2016 ; Lambers et al, 2020 ). Temperature is critical for peanut growth.…”

Responses of Neotropical Savannah Plant Species to Abiotic Stresses: A Structural and Functional Overview

“…The Neotropical savannah soils are considered to be among the most chemically infertile soils in the world [124,125], being generally dystrophic, acidic and poor in available nutrients [126,127], as well as having high levels of exchangeable aluminum (Al) [127,128]. Soils are mainly represented by well-drained oxisols [129], named "latossolos" in the Brazilian soil classification system [130], followed by sandy entisol, ultisol and cambisol soil types [129,131]. Many relevant plant nutrients such as K, Ca, Mg, N, S, and P, are deficient in the soil of most Neotropical savannah physiognomies due to the nutritional deficiency of the initial matrix rocks and the intense weathering that leads to daily loss of nutrients [127].…”
