Dynamically optimizing stomatal conductance for maximum turgor-driven growth over diel and seasonal cycles AoB Plants (IF 2.9) Pub Date : 2023-07-05 Aaron Potkay, Xue Feng
SUMMARY Stomata have recently been theorized to have evolved strategies that maximize turgor-driven growth over plants’ lifetimes, finding support through steady-state solutions, in which gas exchange, carbohydrate storage, and growth have all reached an equilibrium. However, plants do not operate near steady-state as plant responses and environmental forcings vary diurnally and seasonally. It remains

Sources of carbon supporting the fast growth of developing immature moso bamboo (Phyllostachys edulis) culms: inference from carbon isotopes and anatomy AoB Plants (IF 2.9) Pub Date : 2023-07-05 Shitephen Wang, Daniel Epron, Keito Kobayashi, Satoru Takanashi, Masako Dannoura
Phyllostachys edulis is a spectacularly fast-growing species that completes its height growth within two months after the shoot emerges without producing leaves (fast-growing period, FGP). This phase was considered heterotrophic, the carbon necessary for the growth being transferred from the mature culms via the rhizomes, although previous studies observed key enzymes and anatomical features related

Transcriptomic profile of lettuce seedlings (Lactuca sativa L.) response to microalgae extracts used as biostimulant agents AoB Plants (IF 2.9) Pub Date : 2023-07-02 D F Santoro, I Puglisi, A Sicilia, A Baglieri, E La Bella, A R Lo Piero
To reduce the use of chemical fertilizers and maximize agricultural yields, the use of microalgae extracts as biostimulants has recently attracted significant attention due to their favorable impact on both plant growth and their ability to induce tolerance towards environmental stressors. Lettuce (Lactuca sativa L.) is one of the most important fresh vegetables that often requires applications of

Contextualizing the ecology of plant-plant interactions and constructive networks. AoB Plants (IF 2.9) Pub Date : 2023-07-01 Gianalberto Losapio
Botanical concepts have traditionally viewed the environment as a static box containing plants. In this box, plants compete with one another and act as passive resource consumers subjected to the environment in a top-down manner. This entails that plants have only negative effects on other plants and have no influence on the environment. By contrast, there is increasing evidence that plants have positive

Nutritional strategy underlying plant specialisation to gypsum soils AoB Plants (IF 2.9) Pub Date : 2023-06-29 Andreu Cera, Gabriel Montserrat-Martí, Sara Palacio
Gypsum soils are amongst the most widespread extreme substrates of the world, occurring in 112 countries. This type of hypercalcic substrate has a suite of extreme physical and chemical properties that make it stressful for plant establishment and growth. Extreme chemical properties include low plant-available (N) and phosphorus (P) and high plant-available sulphur (S) and calcium (Ca), which impose

A new experimental setup to measure hydraulic conductivity of plant segments. AoB Plants (IF 2.9) Pub Date : 2023-06-15 Louis Krieger,Stanislaus J Schymanski
Plant hydraulic conductivity and its decline under water stress are the focal point of current plant hydraulic research. The common methods of measuring hydraulic conductivity control a pressure gradient to push water through plant samples, submitting them to conditions far away from those that are experienced in nature where flow is suction driven and determined by the leaf water demand. In this paper

Systematic Review on Raphide Morphotype Calcium Oxalate Crystals in Angiosperms AoB Plants (IF 2.9) Pub Date : 2023-06-09 Natasha S Lawrie, Nekane Medrano Cuetos, Francesca Sini, Ghifary A Salam, Hangyu Ding, Arthur Vancolen, Jessica M Nelson, Roy H J Erkens, Giuditta Perversi
Calcium oxalate (CaOx) crystals are biominerals present in a wide variety of plants. Formation of these crystals is a biomineralisation process occurring in vacuoles within specialised cells called crystal idioblasts. This process is dependent on two key components: deprotonated oxalic acid, and calcium ions (Ca 2+), and can result in multiple crystal morphologies. Raphides are needle-like CaOx crystals
