Transformation of Plants Via the Shoot Apex
2003The terms "meristem" and "shoot tip" culture have often been indiscriminately interchanged. According to Cutter 1), the apical meristem refers to only that portion of the shoot apex lying distal to the youngest leaf primordium. The shoot apex, or shoot tip, consists of the apical meristem and one to three subjacent leaf primordia.

Axillary Shoot Branching in Plants
2009The yield of many crop plants is influenced by the number of axillary shoot branches they produce. Plants possess several mechanisms to control axillary branch growth and development. Recently, tremendous progress has been achieved towards gaining a better understanding of these mechanisms, and several novel genes have been identified which are ...

The Geoelectric Effect in Plant Shoots:
Journal of Experimental Botany, 1971Incubation of Zea coleoptiles in 0-5 M mannitol totally inhibits growth and geotropic curva ture, but does not affect the development of the geoelectric effect. This pre-treatment also inhibits the curvature induced by the asymmetrical application of IAA to the apical end of decapitated vertical coleoptiles, but it does not prevent the IAA from giving ...

The Geoelectric Effect in Plant Shoots
Journal of Experimental Botany, 1970The development of the geoelectric effect has been followed in Zea coleoptiles with a flowing solution electrode system, and its dependence upon auxin concentration gradients and aerobic metabolism assessed. A symmetrical source of IAA can effectively replace the coleoptile tip in allowing the geo electric potential to occur.

The Geoelectric Effect in Plant Shoots
Journal of Experimental Botany, 1972In earlier papers Woodcock and Wilkins, and Hertz and Grahm reported measurements of the geoelectric effect (GEE) in Zea mays coleoptiles. While Woodcock and Wilkins attached contact electrodes to the coleoptile directly, Grahm and Hertz employed a vibrating-electrode technique that avoided touching the plant.

In vitro plant regeneration from callus of shoot apices in apple shoot culture
Plant Cell Reports, 2000A new reliable protocol for the induction of adventitious shoot formation and plant regeneration from apple callus has been developed. High regeneration frequency was obtained with this method in four different genotypes (Jork9, M26, Gala and McIntosh) and callus maintained regeneration ability for several months.

Plant hydraulic conductance adapts to shoot number but limits shoot vigour in grapevines
Functional Plant Biology, 2014The rate of shoot growth (vigour) in grapevines tends to decrease as the number of shoots per plant increases. Because the underlying causes of this relationship remain unclear, they were studied by variable pruning of field-grown, deficit-irrigated Merlot grapevines (Vitis vinifera L.).

Development of maize plants from cultured shoot apices
Planta, 1988Excised shoot apices of maize (Zea mays L.), comprising the apical meristem and one or two leaf primordia, have been cultured and can form rooted plantlets. The plantlets, derived from meristems that had previously formed 7-10 nodes, develop into mature, morphologically normal plants with as many nodes as seed-grown plants. These culture-derived plants

Silica in Shoots of Higher Plants
1981In the shoots of vascular plants, silica is deposited as amorphous silica gel, SiO2 · nH2O. It occurs in many plant families including the scouring rushes or horsetails (Equisetaceae), grasses (Poaceae), sedges (Cyperaceae), ginger family (Zingiberaceae), spiderworts (Commelina- ceae), nettles (Urticaceae), elm family (Ulmaceae), vervain family (Ver ...

Fluxes of atmospheric hydrogen sulphide to plant shoots
New Phytologist, 1989summaryShort‐term exposure of maize, pumpkin, spinach and spruce to various atmospheric H2S concentrations resulted in high H2S fluxes to the shoots. In all species an almost linear relation was observed between flux and H2S concentration up to around 0.3 μl −1.
