1. ” Auxins are the main hormones responsible for cell elongation in phototropism and gravitropism

2. The isolation of Aphototropic mutants (i.e., mutants lacking the capacity to exhibit phototropism) in Arabidopsis showed that phototropism can be genetically separated from phytochrome and cryptochrome action

3. 10 The invention discloses a negative phototropism module and its pervasion plate structure.

4. 12 It suggested that the blue light receptor might be the photoreceptor for the negative phototropism in rice root.

5. The relationship between phototropism and the light-growth response of Phycomyces blakesleeanus (Burgeff) sporangiophores was investigated

6. For instance, Auxins are the hormones responsible for phototropism, the growth of a plant toward the light

7. Notably, phot1-7 mutants are Aphototropic (Celaya and Liscum, 2005), demonstrating that phot1 autophosphorylation is essential for phototropism

8.  · The red-light Aphototropic (rap) mutants lack phototropism, polarotropism and chloroplast movement by red light (Kadota and Wada 1999)

9. Moreover, Auxin is important in phototropism as well because Auxin moves to the darker side of the plant and causes for cell division

10. 8 The negative phototropism module mainly contains lamp-house module equipped with light source and pervasion plate structure located on the upper of the lamp-house module.

11. Auxin is the signaling molecule responsible for phototropism and it is an important factor regulating vascular tissue differentiation, leaf blade expansion, maintenance of tissue polarity, and the inhibition of lateral bud development.
