Apical wilting and petiole xylem vessel diameter of the rms2 branching mutant of pea are shoot controlled and independent of a long-distance signal regulating branching.

Abstract excerpt

RMS2 (RAMOSUS2) affects the level or transport of a graft-transmissible signal produced in the shoot and root that controls axillary bud outgrowth in pea (Pisum sativum L.). The shoot apex of rms2 transiently wilts under high evaporative demand. The origin of this phenotype was investigated to determine whether it was involved in the regulation of branching. Wild-type (WT) and rms2 leaves showed a similar...
