Phloem- and xylogenesis in Scots pine stems in the post-fire period [PDF]

open access: yesСибирский лесной журнал, 2023
The influence of natural ground fire of varying intensity on the growth processes in the stems of Scotch pine (Pinus sylvestris L.) trees growing in the Krasnoyarsk forest-steppe was studied. The primary reaction is the decrease in the number of cells in

Multi-Timescale Wavelet Scattering With Genetic Algorithm Feature Selection for Acoustic Scene Classification

open access: yesIEEE Access, 2022
In this paper, we apply a genetic algorithm (GA) for feature selection, wrapper approach, on wavelet scattering (WS) second-order coefficients to reduce the large frequency dimension (>500).

Overexpression of pPLAIIIγ in Arabidopsis Reduced Xylem Lignification of Stem by Regulating Peroxidases

open access: yesPlants, 2022
Patatin-related phospholipases A (pPLAs) are a group of plant-specific acyl lipid hydrolases that share less homology with phospholipases than that observed in other organisms.

Xylem Development and Xylem Conductivity of Furrowed Xylem in Stem Terminals of Five Species of Aristolochia (Aristolochiaceae)

open access: yesJournal of Plant Studies, 2022
Xylem cells are responsible for water transport and mechanical support in most plants. Since vines depend upon other plants for mechanical support, the main responsibility of xylem cells in vines is primarily water transport and not mechanical support.

Xylem Sap Proteins [PDF]

open access: yesPlant Physiology, 1991
Xylem sap from apple (Malus domestica Borkh), peach (Prunus persica Batsch), and pear (Pyrus communis L.) twigs was collected by means of pressure extrusion. This sap contained a number of acidic peroxidases and other proteins. Two other sources of xylem sap used in this study were stem exudates and guttation fluid.

Brassinosteroids promote parenchyma cell and secondary xylem development in sugar beet (Beta vulgaris L.) root

open access: yesPlant Direct, 2021
Increasing crop yield has always been an important goal in agriculture. Brassinosteroids (BRs) are growth‐promoting steroid hormones with vital roles in many root developmental processes.
