Signals Regulating Dormancy in Vegetative Buds
Dormancy in plants involves a temporary suspension of meristem growth, thus insuring bud survival and maintenance of proper shoot system architecture. Dormancy regulation is a complex process involving interactions of various signals through specific and/or overlapping signal transduction pathways. In this review, environmental, physiological, and developmental signals affecting dormancy are di...
متن کاملCryopreservation of Vegetative Dormant Winter Buds
Cryopreservation of vegetative winter buds is an alternative method to preserving plant species in the field. In this method, nodal sections of scionwood are stored in liquid nitrogen vapor. Cryopreservation of the vegetative dormant winter buds involves low maintenance costs and virtually eliminates the risk of germplasm loss. At the NCGRP, this method is routinely used to preserve Malus sp. (...
متن کاملPreformation in vegetative buds of Prunus persica: factors influencing number of leaf primordia in overwintering buds.
We investigated the influence of bud position, cultivar, tree age, tree carbohydrate status, sampling date, drought and light exposure on the number of leaf primordia formed in dormant vegetative peach buds (Prunus persica (L.) Batsch) relative to the number of primordia formed after bud break (neoformed). During winter dormancy, vegetative peach buds from California and Italy were dissected an...
متن کاملWhole-Transcriptome Analysis of Differentially Expressed Genes in the Vegetative Buds, Floral Buds and Buds of Chrysanthemum morifolium
BACKGROUND Chrysanthemum morifolium is an important floral crop that is cultivated worldwide. However, due to a lack of genomic resources, very little information is available concerning the molecular mechanisms of flower development in chrysanthemum. RESULTS The transcriptomes of chrysanthemum vegetative buds, floral buds and buds were sequenced using Illumina paired-end sequencing technolog...
متن کاملIce nucleation activity in various tissues of Rhododendron flower buds: their relevance to extraorgan freezing
Wintering flower buds of cold hardy Rhododendron japonicum cooled slowly to subfreezing temperatures are known to undergo extraorgan freezing, whose mechanisms remain obscure. We revisited this material to demonstrate why bud scales freeze first in spite of their lower water content, why florets remain deeply supercooled and how seasonal adaptive responses occur in regard to extraorgan freezing...
