Defoliation and low temperature in micropropagated apple plants to overcoming the growth cessation during the acclimatization
Abstract : The present work aimed to evaluate the effect of the temperature and defoliation on the growth of micropropagated apple plants, cv. 'Marubakaido', during the acclimatization process

Effect of saline stress and exogenous proline in maize callus
Abstract : This work aimed at evaluating the effect of different NaCl concentrations (0, 68, 137 and 205 mM) in two maize (Zea mays L.) genotypes (W64Ao2 and Arizona 8601) callus cultures in N6 medium

Viabilty evaluation of pollen as possible indicator of high temperature tolerance in tomato genotypes
Abstract : The objective of this research was to evaluate the behavior of five cultivars ( Carmem, IPA- 5, Principe gigante, Santa Clara TSW - 10 ) and tomato line ( CL5915), in relation to high temperature tolerance, using pollen viability.

Sulfur Assimilatory Metabolism. The Long and Smelling Road
Sulfur represents the ninth and least abundant essential macronutrient in plants, preceded by carbon, oxygen, hydrogen, nitrogen, potassium, calcium, magnesium, and phosphorus.

Vertical Gradient in Photosynthetic Properties of Spinach Chloroplasts Dependent on Intra-Leaf Light Environment
The study shows that both the biochemical and ultrastructural properties of the chloroplasts change gradually and continuously from sun- to shade-type with the depth from the adaxial surface.

Construction and Maintenance of the Optimal Photosynthetic Systems of the Leaf, Herbaceous Plant and Tree: an Eco-developmental Treatise
Construction and maintenance mechanisms of efficient photosynthetic systems at three different scaling levels are reviewed mainly based on the nitrogen optimization theory.

Photosynthesis, sugars and the regulation of gene expression
In this review, a compilation of the genes encoding photosynthetic proteins, subject to this mode of regulation, is presented.

Physiological Signals That lnduce Flowering
Both physiological and genetic results support the theory of a multifactorial control of flowering, study shows.

Senescence Is Induced in Individually Darkened Arabidopsis Leaves, but Inhibited in Whole Darkened Plants
The light status of the rest of the plant influences the senescence progression of the individual leaf, study shows.

How Plants Avoid Feeling The Burn
Too much sun – for plants as well as people – can be harmful to long-term health. But to avoid the botanical equivalent of "lobster tans," plants have developed an intricate internal defense mechanism, called photoprotection, which acts like
