Energy Flow from Root to Shoot: A Comprehensive In silico Analysis
Background: Root to shoot connection and transfer of information seems to be taken place mostly via the transmissions of signal molecules, secondary metabolites, amino acids, hormones and proteins, through xylem sap. Examination of earlier reports is indicative of relatively high levels of conservation in xylem sap protein compositions. Apparently these protein molecules are be...
متن کاملChemical root to shoot signaling under drought.
Chemical signals are important for plant adaptation to water stress. As soils become dry, root-sourced signals are transported via the xylem to leaves and result in reduced water loss and decreased leaf growth. The presence of chemical signals in xylem sap is accepted, but the identity of these signals is controversial. Abscisic acid (ABA), pH, cytokinins, a precursor of ethylene, malate and ot...
متن کاملShoot Regeneration and Bulblet Formation from Shoot and Root Meristem of Garlic Cv Bangladesh Local
Tissue culture is considered as an alternative tool for garlic breeding as traditional breeding is not possible due to its sterility. A study was carried out to develop a protocol of regeneration in Bangladesh local garlic. Shoot and root meristems of garlic cv. Bangladesh local were cultured on Murashige and Skoog (MS) medium containing various growth regulator combinations. Regeneration from ...
متن کاملGenetic Control of Root Weight, Root Volume and Root to Shoot Weight Ratio in Peas
The genetic control of root weight, root volume and root to shoot weight ratio was studied in peas (Pisum sativum L.) at flowering. The four populations used were developed from crosses between lines and cultivars differing in size of the root systems. Plants of the F 1, F 2 , backcross and parental generations were evaluated in pots filled with soil: sand mixture, in a completely randomized de...
متن کاملCarbon Allocation to Root and Shoot Systems of Woody Plants
Carbon allocation to roots is of widespread and increasing interest due to a growing appreciation of the importance of root processes to whole-plant physiology and plant productivity. Carbon (C) allocation commonly refers to the distribution of C among plant organs (e.g., leaves, stems, roots); however, the term also applies to functional categories within organs such as defense, injury, repair...
