Biophotonic in situ sensor for plant leaves

Applied Optics, 2010
Knowledge of the water concentration of plants can be helpful in several environmental and agricultural domains. There are many methods for the determination of water content in plant leaves; however, most of them give a relative moisture level or an analytical measure after a previous calibration procedure. Even for other biochemical compounds such as

Superhydrophobic Plant Leaves: The Variation in Surface Morphologies and Wettability during the Vegetation Period.

Langmuir, 2019
In this paper, for the first time, the surface wettability of cloverleaves and lotus leaves with specific surface structures at different growth stages is investigated. It is found that the clover exhibits water-repellent property similar to lotus leaves.

Organogenesis in plants: initiation and elaboration of leaves

Trends in Genetics, 2015
Plant organs initiate from meristems and grow into diverse forms. After initiation, organs enter a morphological phase where they develop their shape, followed by differentiation into mature tissue. Investigations into these processes have revealed numerous factors necessary for proper development, including transcription factors such as the KNOTTED ...

Metabolism of sedoheptulose-C14 in plant leaves

Archives of Biochemistry and Biophysics, 1954
Abstract 1. 1. Sedoheptulose-C14 in leaves in the light and in air is rapidly converted to sucrose. In similar experiments in the dark the sedoheptulose is metabolized to respiratory products such as glutamic, aspartic, and succinic acids. 2. 2.

Does foliar nutrient resorption regulate the coupled relationship between nitrogen and phosphorus in plant leaves in response to nitrogen deposition?

Science of the Total Environment, 2018
Nutrient resorption from senescing leaves is an important process of internal nutrient cycling in plants, but the patterns of nutrient resorption and the coupled relationship between nitrogen (N) and phosphorus (P) in plant leaves as affected by N ...

Superexpression of tuberculosis antigens in plant leaves

Tuberculosis, 2007
Recent developments in genetic engineering allow the employment of plants as factories for 1/foreign protein production. Thus, tuberculosis (TB) ESAT6 antigen was expressed in different plant systems, but the level of vaccine protein accumulation was extremely low. We describe the technology for superexpression of TB vaccine proteins (Ag85B, ESAT6, and

Active Iron in Plant Leaves

Annals of Botany, 1979
Tomato plants were grown with limited or luxury water supply and given nitrogen either as the ammonium ion or the nitrate ion. The 'active' iron fractions of the leaves as extracted by etherized tenth molar hydrochloric acid showed no relationship with the total iron but a very significant linear relationship was found between the active iron fraction ...

Aerosol deposition on plant leaves

Water, Air, and Soil Pollution, 1977
An aerosol generator and wind tunnel system designed for use in aerosol deposition are described. Gross deposition on rough pubescent leaves was nearly seven times greater than on smooth, waxy leaves. Results suggest that aerosol deposition, on a per unit area basis, for single horizontal streamlining leaves is similar to that for arrays of leaves ...
