arc6, A Fertile Arabidopsis Mutant with Only Two Mesophyll Cell Chloroplasts.

abstract：:In angiosperms, auxin phytohormones play a crucial regulatory role in fruit initiation. The expression of auxin biosynthesis genes in ovules and placenta results in uncoupling of tomato (Solanum lycopersicum) fruit development from fertilization with production of parthenocarpic fruits. We have identified two newly de...

abstract：:Recent advances in the development of methods for measuring cytoplasmic Ca(2+) levels in higher plant cells are discussed. Emphasis is placed on the new generation of Ca(2+)-sensitive fluorescent dyes particularly fura-2 and indo-1. These dyes offer many advantages for the measurement of cytosolic Ca(2+) levels. They ...
