Translocation - PowerPoint PPT Presentation


Chromosomal Alterations and Their Impact on Phenotype

Errors in mitosis or meiosis can result in changes in phenotype, often due to alterations in chromosome structure such as deletion, duplication, inversion, and translocation. Nondisjunction can lead to abnormal chromosome number, resulting in disorders like aneuploidy. Polyploidy, with extra complet

Understanding Water Relationships in Plant Physiology

Water plays a crucial role in the physiology of plants, with most absorbed water being translocated to leaves and lost through transpiration and guttation. While essential for turgidity and mineral translocation, plant water use is often inefficient. Transpiration is the primary mode of water loss,

Understanding Root Pressure in Plant Physiology

Root pressure is the pressure developing in xylem vessels due to metabolic activities of the roots. It is an active process driven by osmotic mechanisms and the absorption of salts by the roots. This pressure plays a key role in translocation of water, affecting factors like respiration, exudation r

Plant Mineral Nutrition: Absorption and Circulation of Ions in Roots

Plant mineral nutrition involves the absorption and translocation of ions across roots. Salts are absorbed passively and actively, with ions moving into the root's apoplasm via free diffusion. The Casparian strip in endodermal cells acts as a barrier, allowing ions to pass only through the protoplas

Transport in the Phloem: A Detailed Overview by Ashish Sharma, Ph.D.

The phloem plays a vital role in transporting sugars and organic materials throughout plants. This system involves various specialized cells like sieve elements, companion cells, parenchyma cells, and phloem fibers. Mature sieve elements lack certain organelles and have non-lignified cell walls, mak

Mechanisms of Nutrient Uptake by Microbial Cells

Nutrient uptake by microbial cells involves various transport mechanisms such as passive diffusion, facilitated diffusion, active transport, and group translocation. These mechanisms ensure the specific acquisition of required nutrients by the cell through the selectively permeable plasma membrane.

Understanding Translocation in the Phloem

This lecture explores the process of translocation in the phloem, supported by evidence from studies such as aphid experiments, ringing experiments, and the use of radioactive isotopes. It delves into the materials translocated in phloem sap, including water, sucrose, non-reducing sugars, nitrogen c

Understanding Down Syndrome: Types, Characteristics, and Impacts

Down syndrome is a genetic condition caused by an extra chromosome, typically chromosome 21. This leads to physical and cognitive challenges, with individuals exhibiting unique abilities. The syndrome presents with distinctive physical features, such as flattened face, almond-shaped eyes, and poor m

Herbicide Absorption and Translocation Mechanisms in Plants

Herbicides need to be effectively absorbed and translocated within plants to interfere with physiological and biochemical processes. Soil-applied herbicides are absorbed by roots, shoots, and seeds through different mechanisms, while foliage-applied herbicides enter through the cuticle, stomata, and

Role of REG3 and I-FABP in HIV-Related Gut Permeability and Inflammation

This presentation highlights the significance of Regenerating Islet-Derived Protein-3 (REG3) and Intestinal Fatty Acid Binding Protein (I-FABP) in microbial translocation, inflammation, and reservoir size in individuals living with HIV. REG3 and I-FABP serve as markers of gut epithelial damage and p

Comprehensive Analysis of Policies and Laws on Feral Swine Translocation

Research and analysis conducted to assess the statutes, regulations, and policies relating to the translocation of live feral swine across all 50 U.S. states. The study aimed to enhance uniformity and effectiveness by providing recommendations based on state wildlife agency responses, surveys, and l

Lipophilicity and Translocation of Chemicals in Plants: Exploring the Relationship Between Log.D and TSCF

A study investigates the correlation between the lipophilicity of chemicals and their translocation in intact plants. The focus is on the relationship between log.D values and the Transpiration Stream Concentration Factor (TSCF). Various curves are proposed to describe this relationship, aiming to r
