Single applications of either 6-benzyladenine or zeatin to inhibited axillary buds of intact, light-grown seedlings of Pisum sativum L. cv Black-eyed Susan, resulted in the formation of rapidly elongating, leafy shoots. Similar treatment with kinetin or isopentenyladenine caused only limited but outgrowth which stopped 6 days after application.

Plant architecture and subsequent productivity are determined by the shoot apical dominance, which is disturbed by the deficiency of boron, one of the essential trace elements for plant growth and reproduction. However, the mechanism by which B controls shoot apical dominance or axillary bud outgrows under B deficiency is still unclear. This work aimed to investigate the mechanistic basis of this process, with focus on the interaction between B and polar auxin transport.

The ability of axillary meristems to form axillary buds and subsequently develop into branches is influenced by phytohormones, environmental conditions, and genetic factors. The main trunk of Quercus fabri is prone to branching, which not only impacts the appearance and density of the wood and significantly reduces the yield rate. This study conducted transcriptomic, proteomic, and metabolomic analyses on three stages of axillary bud development in Q.

Background: P. yunnanensis, a distinctive economic tree species native to Yunnan Province in China, possesses axillary buds that serve as superior material for asexual propagation. However, under natural growth conditions, the differentiation of these axillary buds is notably scarce.

The source-sink relationship is critical for proper plant growth and development, particularly for vegetative axillary buds, whose activity shapes the branching pattern and ultimately the plant architecture. Once formed from axillary meristems, axillary buds remain dormant or become active to grow into new branches. This transition is notably driven by the regulation of the bud sink strength, which is reflected in the ability to unload, metabolize and store photoassimilates.
