Embodiment Construction

[0125] 1. The effect of HTS on pollen development and germination

[0126] The effect of HTS on pollen development and germination in figure 1 been confirmed in. Pollen from tomato plants grown at normal temperature (28 / 22°C day / night) had good viability after germination at 23°C and significantly reduced viability after germination at 32°C, pointing to the effect of HTS on pollen germination negative effects. Pollen from plants grown at high temperatures (32 / 36°C) also showed lower viability when germinated at 23°C, pointing to a persistent negative effect of HTS on pollen development.

[0127] 2. Overexpression of AtHXK1 improves the development and germination of tomato pollen under HTS

[0128] To investigate the importance of hexose phosphorylation in determining the germination ability of pollen, pollen germination was analyzed in tomato plants overexpressing the Arabidopsis hexokinase gene (AtHXK1) (35S::AtHXK1) under the control of the CaMV35S promoter [8]. Altho...

Abstract

A method for protecting a plant from high temperature stress (HTS), comprising transforming the plant with a polynucleotide sequence. The polynucleotide sequence comprises a nucleotide sequence encoding a sugar kinase under the control of an anther and / or pollen specific promoter, thereby producing a transformed plant having improved tolerance to HTS. Also disclosed is the polynucleotide sequence of the LeFRK4 promoter.
