Phosphate Solubilisation

A phosphate-solubilising isolate of Penicillium radicum (sp. nov.) was used to inoculate wheat (Triticum aestivum cv. Dollarbird) in a glasshouse experiment and a field trial, using low pH soils at 5 levels of phosphate application. When data for all phosphate application levels were combined, inoculation by P. radicum resulted in 14% increases in wheat yield in the field trial and increases in both phosphate uptake (10%) and yield (9%) in the glasshouse. In the glasshouse, the response to inoculation was higher at the nil phosphate application level (17%) than for the combined phosphate application levels (9%). This negative interaction indicates that growth promotion could be partially due to soil phosphate solubilisation by the fungus, with a greater response for soils with lower available P. However, other plant-growth promotion mechanisms may also be involved.

To study the effects of salt stress and plant growth regulators (kinetin, gibberellic acid, potassium) on growth, yield, glycine betaine content, phosphoenolpyruvate carboxylase (PEPC) and ribulose biphosphate carboxylase (RBC) gene expression of two Libyan bread wheat varieties, a factorial design of greenhouse experiment with three replications was conducted. Results revealed that salt stress significantly reduced plant growth and productivity of both varieties. Moreover, the addition of kinetin + potassium and gibberellic acid + potassium had improved the performance of the morpho-metric parameters of both genotypes under salt stress; but the performance was more effective for kinetin treatment than for gibberellic acid. At the biochemical level, the results showed that salt stress increased glycine betaine contents in both varieties with different proportions. This increase is more elevated in the presence of kinetin + potassium than the treatment with gibberellic acid+ potassium, which showed an almost similar result as in only salt stress. At the molecular level, the effects of salt stress and plant growth regulators on the PEPC and RBC gene expression showed that the increase was significantly higher for kinetin, gibberellic acid, and salt stress when compared to the control.

Trimethylammonium Chloride

Classically the plant-growth regulator chlormequat (2-ohlorethyl trimethylammonium chloride, CCC) is applied to bread wheat crops (Triticum aestivutn L.) to shorten the basal internodes of the culm (Koranteng & Matthews, 1982) and thus prevent lodging (Cyanamid, 1966). Further, yield variations in cereal crops can be induced by chlormequat application in the absence of lodging. These effects may result from a manipulation of growth (e.g. barley: Koranteng & Matthews, 1982; wheat: Wunsche, 1971; triticale: Hankins, 1975) or development (e.g. barley: Wunsche, 1972; wheat: Harris, 1978; triticale: Green & McDonald, 1985).

Cortex Cell

Central to the mutualistic arbuscular mycorrhizal symbiosis is the arbuscule, the site where symbiotic phosphate is delivered. Initial investigations in legumes have led to the exciting observation that symbiotic phosphate uptake not only enhances plant growth but also regulates arbuscule dynamics and is, furthermore, required for maintenance of the symbiosis. This review evaluates the possible role of the phosphate ion, not only as a nutrient but also as a signal that is necessary for reprogramming the host cortex cell for symbiosis.

Wide Range

The PACLOBUTRAZOL-RESISTANCE (PRE) gene family encodes a group of atypical helix-loop-helix (HLH) proteins that act as the major hub integrating a wide range of environmental and hormonal signals to regulate plant growth and development. PRE1, as a positive regulator of cell elongation, activates HBI1 DNA binding by sequestering its inhibitor IBH1. Furthermore, PRE1 can be phosphorylated at Ser-46 and Ser-67, but how this phosphorylation regulates the functions of PRE1 remains unclear. Here, we used a phospho-mutant activity assay to reveal that the phosphorylation at Ser-67 negatively regulates the functions of PRE1 on cell elongation. Both of mutations of serine 46, either to phospho-dead alanine or phospho-mimicking glutamic acid, had no significant effects on the functions of PRE1. However, the mutation of serine 67 to glutamic acid (PRE1S67E-Ox), but not alanine (PRE1S67A-Ox), significantly reduced the promoting effects of PRE1 on cell elongation. The mutation of Ser-67 to Glu-67 impaired the interaction of PRE1 with IBH1 and resulted in PRE1 failing to inhibit the interaction between IBH1 and HBI1, losing the ability to induce the expression of the subsequent cell elongation-related genes. Furthermore, we showed that PRE1-Ox and PRE1S67A-Ox both suppressed but PRE1S67E-Ox had no strong effects on the dwarf phenotypes of IBH1-Ox. Our study demonstrated that the PRE1 activity is negatively regulated by the phosphorylation at Ser-67.
