Arabidopsis Thaliana Plants with Mutations in the LRB1 and 2 Genes Show Reduced Germination Inhibition By Salt

Abstract

Light is vital to plant survival and thus plants have developed sophisticated pathways to respond properly to their light environments. Plants sense specific wavelengths of light via photoreceptors, one family of which are the red (R)/far-red (FR)-absorbing phytochromes (phys). Here we present data from experiments conducted to confirm this result and to see if this effect is simply the byproduct of the over-activation of the red light pathway or if the LRB genes have roles in the germination process independent of their roles in red light signaling.
