Ramon et al. show how plants have modified the ancient, highly conserved eukaryotic energy sensor to better fit their unique lifestyle and cope with changing environmental conditions.

The polar subcellular localization of the auxin efflux machinery determines the directionality of auxin flow in plants. In particular, the dynamics of polar localization of PIN proteins regulates the rate and direction of cellular auxin export and this ultimately determines auxin gradients in the tissue.…

The tapetum is the innermost layer of the anther and encloses the locule wherein pollen develops. In addition to supplying nutrients for pollen growth, the tapetum synthesizes and transfers pollen outer wall precursors for the formation of the pollen outer wall. To synthesize, secrete, and transfer materials…

In rice (Oryza sativa), both the male and female floral organs are produced in the same flower: thus, only rarely do rice grains result from cross-pollination. Since cross-pollination is difficult in rice so, too, is the production of hybrid seed. Plants with defective stigmas may have commercial value…

Membrane proteins are synthesized in the endoplasmic reticulum and are trafficked through the Golgi, from which they are sorted to the plasma membrane, tonoplast, or other target membranes. In all eukaryotes, secretory traffic to the plasma membrane is mediated by SNARE proteins. In Arabidopsis, three…

Many plant species actively reorient their organs in response to dynamic environmental conditions. Petiole hyponasty is an upward movement of petioles driven by a higher rate of cell expansion on the lower (abaxial) compared with the upper (adaxial) side. Hyponasty is common among rosette species facing…
