fish may experience periods of food deprivation or starvation in nature (such as seasonal migration and reproduction) and under culture conditions (unpredictable stress such as transporting and sorting). with respect to vital role of starvation periods on body composition, the current study was carried out in autumn 2010 at international sturgeon research institute. after adaptation for one mon...

When confronted with inorganic phosphate (Pi) starvation, plants activate an array of adaptive responses to sustain their growth. These responses, in a large extent, are controlled at the transcriptional level. Arabidopsis (Arabidopsis thaliana) PHOSPHATE RESPONSE1 (PHR1) and its close homolog PHR1-like 1 (PHL1) belong to a 15-member family of MYB-CC transcription factors and are regarded as th...

In order toexplore the regulation mechanism of macadamia fruitlet abscission induced by ‘starvation stress’, a treatment girdling and defoliation was applied to bearing shoots cultivar ‘H2’ at early stage fruit development, simulating starvation stress interrupting carbon supply fruit. The levels carbohydrates, hormones, related gene expression in different tissues (husk, seed, pedicel) were in...

Pseudomonas aeruginosa was shown to be attracted to phosphate. The chemotactic response was induced by phosphate starvation. The specificity of chemoreceptors for phosphate was high so that no other tested phosphorus compounds elicited a chemotactic response as strong as that elicited by phosphate. Competition experiments showed that the chemoreceptors for phosphate appeared to be different fro...
