| However, the intercalary meristem is considerably longer when considering the leaf extension zone. |
|
| Leaves are formed from an intercalary meristem which is positioned within the leaf sheaths of subtending leaves. |
|
| Thus, significant inflorescence and floral meristem activity is restored to stm null mutant plants in the absence of ULT1 function. |
|
| The coleoptile and coleorhiza are sheaths that enclose the apical meristem of the shoot and root respectively. |
|
| The reproductive shoot apex contains the indeterminate, primary inflorescence meristem that produces the main inflorescence axis of the plant. |
|
| Superficially it appears to be a periclinal chimera with a chlorophyll-deficient mutation in the second layer of the meristem. |
|
| Flower meristem, flower buds, and leaves from green and 2 d-etiolated plants were analysed for ATP and ADP contents. |
|
| It was from this histogenetic rather than cellular conception of the meristem that Hanstein's Histogen Theory was developed. |
|
| Therefore, no data were available in these species for the developmental transition of meristem from the juvenile to the mature foliose root. |
|
| The distinct morphology of this and other brain cacti, known as cristate or crested growth, is caused by an apical meristem gone awry. |
|
| The geometrical analysis yields the principal curvatures and the Gaussian curvature for each cell on the reconstructed meristem surface. |
|
| A near hyperbolic relationship between respiration rates and meristem radii was observed. |
|
| The flower meristems are produced acropetally by the inflorescence meristem and are subtended by bracts. |
|
| Cytokinins were analysed in leaf extracts, leaf phloem exudate and in the shoot apical meristem at different times during floral transition. |
|
| Damage caused to DNA may, in turn, induce mutation and chromosome abnormalities of the meristem cells. |
|
| In lupins, division of the shoot meristem into four quadrants gives four new meristems that each develop a shoot. |
|
| The floral meristems are formed acropetally and are initiated on the periphery of the inflorescence meristem, being protected by bracts. |
|
| Instead of leaves, a floral meristem gives rise in sequence to sepals, petals, stamens, and carpels. |
|
| It is not clear whether this acropetal increase of flower meristem identity is related to the acropetal loss of the SD suppression. |
|
| Similarly, meristem activities in the same acropetal sequence or on the whole-root-system architecture have not yet been compared. |
|
|
|
| In graminaceous plants, leaf cells divide from a basal meristem, which causes older cells to be displaced by younger cells below them. |
|
| From this and related work it has become necessary to define a meristem by its phyllotaxy and other growth patterns and not the identity of organs it produces. |
|
| Three weeks after transfer to the regeneration medium, frozen meristem re-growth is determined under a binocular microscope. |
|
| During normal meristem culture and storage under limited growth conditions, the presence of endogenous bacteria is rarely observed. |
|
| Cell division occurs mainly at the intercalary meristem at the base of the internode, but also throughout the internode at early stages of internode development. |
|
| Unfortunately, current knowledge on architecture and programming of shoot meristem was not used in this explanation to support genetic results against diplontic selection. |
|
| Now you need to make a lateral cut on the left side of the bract, be careful not to harm the meristem or the flower spike behind it. |
|
| Modelling mechanical constraints in the epiderm of the meristem after ablation of a cell. |
|
| Control of the virus can be achieved by thermotherapy or meristem culture, combined with planting of certified virus-free material. |
|
| The cork cambium is, like the vascular cambium, a lateral meristem that produces cells internally and externally by tangential divisions. |
|
| This primary growth is derived from a primary-thickening meristem under the leaf bases that is a lateral continuation of the apical meristem. |
|
| This primary-thickening meristem produces vast amounts of parenchyma to the inside, through which the leaf traces differentiate. |
|
| In the first step, a leaf primordium is formed that involves a switch from indeterminate to leaf developmental fate in the shoot apical meristem cells. |
|
| The stem cell population resides at the very apex of the meristem and replenishes those cells that are lost during organogenesis on the meristem flanks. |
|
| Scanning electron micrographs provide a reference for each stage to illustrate the progression from vegetative meristem to inflorescence meristem and floral organs. |
|
| Because the blade of grass-type monocots elongate due to activity of the intercalary meristem at the blade base, the tip of the blade is more aged than the base. |
|
| The fusion of the corolla lobes to a sympetalous corolla is late taking place by meristem incorporation and fusion across the backs of the anther primordia. |
|
| A model has been established which predicts the responses of leaf growth rate to soil water status, air humidity, and the temperature of the meristem. |
|
| The development of monocotyledonous leaves after initiation of cell division on the shoot apical meristem is different from that of dicotyledons and results in leaves with different morphologies from those of dicotyledons. |
|
| On the potato cultivar Pérola, EEC copper mixture at a rate of 1:10,000 controlled Phytophthora but resulted in a certain degree of phytotoxicity in the apical meristem, as shown by reduced growth. |
|
|
|
| The region of cell division includes the apical meristem and the primary meristems the protoderm, ground meristem, and procambium derived from the apical meristem. |
|
| The phytotoxic effect was scored visually on the meristem of the plants. |
|
| Bioversity-supported research at KULeuven has resulted in the development of three cryopreservation protocols suitable for the longterm storage of meristem cultures of banana. |
|
| On capsicum affected plants develop: chlorotic or pale green leaves, sharp tapering of leaf apex, upward leaf curling, shortened internodes and petioles, necrosis of apical meristem, flower abortion, and plant stunting. |
|
| Together, our results demonstrate a role for long-distance basipetal transport of cytokinin in controlling polar auxin transport and maintaining the vascular pattern in the root meristem. |
|
| Their flowers, appearing on the apical meristem, have the anthers fused along the edges, forming a column surrounding the pistil's style. |
|
| Science project idea where you will study plant mitosis using prepared slides of onion root tips and will calculate the relative period of the phases of mitosis in the meristem of root tissue. |
|
| In the stem apex, the uppermost part is the promeristem, below which is a zone of transversely oriented early cell walls, the file, or rib, meristem. |
|
| As the meristems begin to regrow following cryopreservation, endogenous bacteria present can develop into yellow or white colonies, which overgrow the recovering meristem. |
|
| In grasses, the pair of spikelets is a shBr that produces a single lateral meristem and then terminates in a spikelet. |
|
| The findings of these studies revealed that the formation of new organs in apical meristem regions is regulated, on the cellular scale, by an auxin transport mechanism. |
|
| Currently, droplet-vitrification of apical meristems as well as dropletvitrification of 'cauliflower-like' meristem clusters are both applied to the Musa collection. |
|
| The roots contain large quantities of meristem, a formative tissue specific to plants and valued in cosmetology as an anti-irritant and soothing agent. |
|
| In the pleroma of hyacinth and pea roots, tmin increases along the meristem, especially in its basal part. |
|
| Growth occurs at the base of the meristem, where the blades and stipe meet. |
|
| Intercalary meristems are the internode regions where cell division of the ground meristem persists for a longer time than in other areas of the internode. |
|
| Ultimately, at maturity, no localized meristem remains. |
|
| Epicotyl Axis of the embryonic plant above the cotyledon, terminating in the apical meristem, sometimes bearing scale leaves. |
|
| The meristem that gives rise to each new geotropic tuber is exogenous, formed from surface tissue where the leaves and strobili join the old tuber. |
|
| Hornworts have no specialized structures to aid spore dispersal but a unique intercalary meristem results in relatively long period of spore production. |
|
|
|
| To my mind, the published form of Dyckia estevesii can be likened to the monstrose crested forms of cactus where the meristem only divides distichously. |
