▪ Abstract  Perhaps in keeping with their enigmatic name, 14-3-3 proteins offer a seemingly bewildering array of opportunities for interaction with signal transduction pathways. In each organism there are many isoforms ...

▪ Abstract  Plants, some fungi, and protists contain a cyanide-resistant, alternative mitochondrial respiratory pathway. This pathway branches at the ubiquinone pool and consists of an alternative oxidase encoded by the ...

▪ Abstract  To cope with environmental fluctuations and to prevent invasion by pathogens, plant metabolism must be flexible and dynamic. Active oxygen species, whose formation is accelerated under stress conditions, must ...

▪ Abstract  Asymmetric cell divisions generate cells with different fates. In plants, where cells do not move relative to another cell, the specification and orientation of these divisions is an important mechanism to ...

▪ Abstract  Indole-3-acetic acid (IAA) is the most abundant naturally occurring auxin. Plants produce active IAA both by de novo synthesis and by releasing IAA from conjugates. This review emphasizes recent genetic experiments ...

▪ Abstract  The aerial surfaces of plants are covered with a wax layer that is primarily a waterproof barrier but that also provides protection against environmental stresses. The ubiquitous presence of cuticular wax is ...

▪ Abstract  Jasmonic acid and its derivatives can modulate aspects of fruit ripening, production of viable pollen, root growth, tendril coiling, and plant resistance to insects and pathogens. Jasmonate activates genes ...
