Plant shoot systems give rise to characteristic above-ground plant architectures. Shoots are formed from axillary meristems and buds, whose growth and development is modulated by systemic and local signals. These cues convey information about nutrient and water availability, light quality, sink/source organ activity and other variables that determine the timeliness and competence to maintain de...

Soil nutrients, dormant axillary meristem availability, and competition can influence plant tolerance to damage. However, the role of potential bud banks (adventitious meristems initiated only after injury) is not known. Examining Central European field populations of 22 species of short-lived monocarpic herbs exposed to various sources of damage, we hypothesized that: (1) with increasing injur...

Azadirachta indica A. Juss., (Neem), a prodigious multipurpose tree, has immense potential to benefit mankind and protect the environment. In order investigate effects of three different explants for its regeneration potential, de embryonated cotyledon, immature zygotic embryo nodal segments from 30 year old neem plus tree were used. Half strength MS medium with benzyl amino purine (3 mg/L) nap...

Tree architecture develops over time through the collective activity of apical and axillary meristems. Although the capacity of both meristems to form buds is crucial for perennial life, a comparative analysis is lacking. As shown here for hybrid aspen, axillary meristems engage in an elaborate process of axillary bud (AXB) formation, while apical dominance prevents outgrowth of branches. Devel...

The study was undertaken to examine banana cv. Kanthali floral bud apex as an alternative source material for in vitro propagation because huge number of explants die due to microbial contamination in case of shoot tip explants. Contamination free cultures were established by treating the floral bud explants with 0.1% HgCl2 for 6 min. This study found that inflorescence tissues of experimental ...

Previous spaceflight reports attribute changes in plant ultrastructure to microgravity, but it was thought that the changes might result from growth in uncontrolled environments during spaceflight. To test this possibility, potato explants were examined (a leaf, axillary bud, and small stem segment) grown in the ASTROCULTURETM plant growth unit, which provided a controlled environment. During t...

Plants alter their development in response to changes in their environment. This responsiveness has proven to be a successful evolutionary trait. Here, we tested the hypothesis that two key environmental factors, light and nutrition, are integrated within the axillary bud to promote or suppress the growth of the bud into a branch. Using petunia (Petunia hybrida) as a model for vegetative branch...

BACKGROUND AND AIMS Dendrobium longicornu, commonly known as the 'Long-horned Dendrobium', is an endangered and medicinally important epiphytic orchid. Over-exploitation and habitat destruction seriously threaten this orchid in Northeast India. Our objective was to develop an efficient protocol for the mass propagation of D. longicornu using axillary bud segments. METHODOLOGY AND PRINCIPAL RE...

norfolk island pine (araucaria excelsa) is belonging to araucariaceae family and is native to norfolk island in australia. this plant is a woody ornamental plant of high commercial value. since it is propagated by seed, achieving a regeneration system is one of the most important goals in this woody plant tissue culture. to evaluate the effect of cytokinins and culture media for bud induction d...
