“…On the other hand, Suttle and Hulstrand [30] were able to induce earlier dormancy release after application of fluridone, which considerably reduced the amount of endogenous ABA. However, the role of ABA for maintenance of dormancy has been questioned based on results where ABA concentration was not reduced during dormancy release [31,32]. In the present study, low temperatures induced a rather synchronous increases and/or alterations in ABA levels in both ecotypes tested, but the northern ecotype had larger change in ABA levels than the southern ecotype.…”

“…Poor rooting of microcuttings of many woody crops and the fluctuations in rooting from one subculture to the other (Denissen et al, 1992) may be due to incomplete rejuvenation. Dormancy in buds of plants grown under natural conditions is induced by short day-length or low temperature (Powell, 1987). Lack of rooting in cuttings from dormant plants has frequently been reported.…”

“…Under appropriate conditions, growing buds can reenter a dormant state and, subsequently, can be stimulated to grow again (this report). Seasonal cycles of growth and dormancy occur in overwintering buds of woody plants (25). We previously analyzed protein expression in axillary buds of pea using two-dimensional gel electrophoresis (29; J.P. Stafstrom, unpublished results).…”

Axillary buds of intact pea seedlings (Pisum sativum L. cv Alaska) do not grow and are said to be dormant. Decapitation of the terminal bud promotes the growth of these axillary buds, which then develop in the same manner as terminal buds. We previously showed that unique sets of proteins are expressed in dormant and growing buds. Here we describe the cloning, sequencing, and expression of a cDNA clone (pGB8) that is homologous to ribosomal protein L27 from rat. RNA corresponding to this clone increases 13-fold 3 h after decapitation, reaches a maximum enhancement of about 35-fold after 12 h, and persists at slightly reduced levels at later times. Terminal buds, root apices, and elongating internodes also contain pGB8 mRNA but fully expanded leaflets and fully elongated internodes do not. In situ hybridization analysis demonstrates that pGB8 mRNA increases in all parts of the bud within 1 h of decapitation. Under appropriate conditions, growing buds can be made to stop growing and become dormant; these buds subsequently can grow again. Therefore, buds have the capacity to undergo multiple cycles of growth and dormancy. RNA gel blots show that pGB8 expression is reduced to dormancy levels as soon as buds stop growing. However, in situ hybridization experiments show that pGB8 expression continues at growing-bud levels in the apical meristem for 2 d after it is reduced in the rest of the bud. When cultured stems containing buds are treated with indoleacetic acid at concentrations > 10 gM, bud growth and expression of pGB8 in the buds are inhibited.
