Plant hormones such as auxin and ethylene have an important role in adventitious root development. Periods of excess rain reduce the amount of oxygen that is available to roots and restricts gas ...

This can be a problem ... Ethylene is an essential plant hormone at low concentrations. Concentrations in the field rarely exceed 5 nmol⋅mol−1 (0.005 ppm), but it can accumulate as a gas in ...

Dutch phytopathologists have shown that ethylene is vital for the protection of plants against bacteria and fungi. This is another function for the plant hormone already known to play a role in ...

The volatile plant hormone ethylene allows plant roots to sense and avoid compacted soils, researchers report. Rendering roots insensitive to ethylene allowed them to penetrate compacted soils ...

The cause of fruit ripening is a natural form of a chemical synthesized to make PVC (polyvinyl chloride) piping and plastic bags—namely, a gaseous plant hormone called ethylene. For thousands of ...

The culprit? Ethylene, a naturally occurring plant hormone that drives ripening and can shorten the shelf life of produce, often causing fruits and vegetables to spoil before you can get around to ...

Ethylene is an important plant hormone. In bananas and many other fruits, production of ethylene surges when the fruit is ready to ripen. This surge triggers the transformation of a hard ...

Plant growth and development is regulated by a structurally unrelated collection of small molecules called plant hormones. During the last 15 years the number of known plant hormones has grown ...
