Editorial: Plant cuticle: From biosynthesis to ecological functions
Bibliographic record
Abstract
Plant cuticle: From biosynthesis to ecological functionsAt the interface between the plant and the environment, the cuticle functions as a barrier to water loss and as a protective layer against pathogens and UV light (Kunst and Samuels, 2009;Yeats and Rose, 2013).Over the last decades, numerous researchers from different fields have investigated the chemistry, structure, biosynthesis and functional properties of the plant cuticle, bringing new questions and insights, and significantly enriching our understanding of its structure, chemical composition, physical properties, natural variability, development, and functions.In the current scenario of global climate change, it is crucial to understand the biophysical properties of the cuticle as well as how environmental factors, including temperature, UV radiation and relative humidity, modulate cuticle deposition and its functional properties (Domıńguez et al., 2011).Seufert et al. report on the influence of different wax fractions on the water transpiration properties of isolated leaf cuticles.Using a differential extraction protocol, the authors studied the influence of triterpenoids and very-long-chain aliphatics (VLCA) on water permeability in cuticles from several species.Comparison of water permeance from isolated cuticles and selectively dewaxed cuticles showed that the cuticle components that greatly affect its transpiration barrier function are mainly VLCAs, and that triterpenoids barely contribute to the water barrier properties of the cuticle.Chen et al. compare adaxial and abaxial cuticle transpiration in detached tea leaves from eight different cultivars.Total leaf cuticle transpiration correlated with abaxial transpiration.Among the different wax classes, VLCA and glycol esters negatively correlated with leaf cuticle transpiration.Additionally, intracuticular waxes were the major water barrier in the adaxial leaf surface and epicuticular waxes in the abaxial side.Low water transpiration rate is also important for extending the life of cut ornamental flowers.Cheng et al. used oriental lily to investigate flower cuticle transpiration and wax chemical composition, showing a higher amount of waxes, largely n-alkanes, in tepals than in leaves.However, leaves presented lower water permeance than tepals, a result that the Frontiers in Plant Science frontiersin.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
