Usage

Uses

Used in Plant Biology and Agriculture:
PBI 51 is used as a growth regulator for enhancing plant growth and development. By inhibiting the ABA receptor and its signal transduction, PBI 51 can potentially improve crop yields and stress tolerance in various agricultural applications.
Used in Stress Response Research:
In the field of plant stress response research, PBI 51 is used as a tool to study the role of abscisic acid in plant stress signaling. This can help researchers better understand the mechanisms behind plant adaptation to environmental stressors and develop strategies to improve plant resilience.
Used in Plant Genetic Engineering:
PBI 51 can be utilized in plant genetic engineering to create genetically modified organisms (GMOs) with enhanced growth characteristics and stress tolerance. By suppressing the ABA receptor and its signal transduction, these genetically modified plants may exhibit improved performance under various environmental conditions.

SYNTHESIS AND BIOLOGICAL ACTIVITY OF ALLENIC ANALOGUES OF ABSCISIC ACID

Key Word Index - Lemma gibba; Lemnaceae; abscisic acid; ABA; ABA analogue; allene; turion; growth inhibition.Abstract - Novel allenic analogues of abscisic acid (ABA) were synthesized and tested for ABA activity.The allene functional group was introduced by one of two methods: base catalysed isomerization of an enyne to an enallene conjugated to a ketone, or reduction of a 2-butyn-1,4-diol to an allenic alcohol.A 3:1 mixture of (E)- and (Z)-3-methyl-5-(4',4'-ethylenedioxy-2',6',6'-trimethylcyclohex-2'-en-1'-ylidene)-2,4,5-pentatrienoic acids strongly inhibited growth of axenic duckweed (Lemna gibba) causing a 50percent reduction in frond number at 60 μgl-1 over 7 days in continuous light.Racemic ABA caused the same inhibition at 130 μgl-1.The mixture caused the production of turion-like structures, an effect known hitherto to be induced only by short photoperiods or by certain concentrations of ABA.
