Axillary buds are located at the intersection of the leaf and stem of a plant. The axillary bud (or lateral bud) is an embryonic or organogenic shoot located in the axil of a leaf. Each bud has the potential to form shoots, and may be specialized in producing either vegetative shoots (stems and branches) or reproductive shoots . Once formed, a ...
In botany and dendrology, a rhizome (/ ˈ r aɪ z oʊ m / RY-zohm) [note 1] is a modified subterranean plant stem that sends out roots and shoots from its nodes. Rhizomes are also called creeping rootstalks or just rootstalks. [3] Rhizomes develop from axillary buds and grow horizontally. The rhizome also retains the ability to allow new shoots ...
The nodes are the points of attachment for leaves and can hold one or more leaves. There are sometimes axillary buds between the stem and leaf which can grow into branches (with leaves, conifer cones, or flowers). [2] Adventitious roots (e.g. brace roots) may also be produced from the nodes. Vines may produce tendrils from nodes.
axillary, when located in the axil of a leaf (lateral is the equivalent but some adventitious buds may be lateral too); adventitious , when located elsewhere, for example on the trunk or roots (some adventitious buds may be former axillary ones that are reduced and hidden under the bark, while other adventitious buds are completely new formed ...
In pines, the leaf primordia develop into buds, which eventually elongate into shoots, then stems, then branches. [5] Though primordia are typically only found in new flower and leaf growth, root primordia in plants can also be found, but are typically referred to as lateral root primordium or adventitious roots.
Lateral shoots/branches are often numerous on larger vegetation such as certain trees or bushes. A lateral shoot , commonly known as a branch , is a part of a plant's shoot system that develops from axillary buds on the stem's surface, extending laterally from the plant's stem .
A study that regulated leaf senescence in tobacco leaves found that wild-type leaves yellowed while transgenic leaves remained mostly green. It was hypothesized that cytokinin may affect enzymes that regulate protein synthesis and degradation. [14] Cytokinins have recently been found to play a role in plant pathogenesis.
The roots are modified to have root hairs and branch indiscriminately with cells that take in water and nutrients, while the stems are modified to move water and nutrients to and from the leaves and flowers. [8] [9] [10] Stems have nodes with buds where leaves and flowers arise at
