Studies on lignification in wheat (Triticum aestivum var. Thatcher) : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Botany at Massey University [PDF]

open access: yes, 1975
PART I Transections of the stem of Triticum were examined after staining with dyes specific for functional groups within the lignin polymer. Anatomical observations suggest that the basis for the rapid increase in the lignin content of this plant 35 to ...

On the origin of highly-numbered vascular bundles of coleoptile of cereal crop plants.

open access: yesJapanese Journal of Crop Science, 1950
Though the coleoptile is typically a two-bundled structure, occasionally a higher number of strands occur. In this paper the author will show at least two cases on the origin of them. (1) First case : After originating from the lower strands simultaneously in like manner and going together, the normal and supplementary bundles are separated each other.

Natural Variation in the Flag Leaf Morphology of Rice Due to a Mutation of the NARROW LEAF 1 Gene in Oryza sativa L. [PDF]

open access: yes, 2015
We investigated the natural variations in the flag leaf morphology of rice. We conducted a principal component analysis based on nine flag leaf morphology traits using 103 accessions from the National Institute of Agrobiological Sciences Core Collection.

Spatio-temporal dynamics of phytohormones in the tomato graft healing process

open access: yesHorticultural Plant Journal
Graft healing involves a series of cytological and molecular events including wound responses, callus formation and vascular bundle remodelling. Hormones are important signalling molecules regulating plant development and responses to environmental ...

Plasmodesmatal frequency in relation to short-distance transport and phloem loading in leaves of barley (Hordeum vulgare). Phloem is not loaded directly from the symplast [PDF]

open access: yes, 1997
We investigated the phloem loading pathway in barley, by determining plasmodesmatal frequencies at the electron microscope level for both intermediate and small blade bundles of mature barley leaves.

Observations on the Occurrence of Highly-Numbered Vascular Bundles in Coleoptile of Rice Plant.

open access: yesJapanese Journal of Crop Science, 1954
The present report deals with the variability of coleoptile nervation in the kernels obtained under different environments. The author grew a strain of rice variety "Tokyo-Tozomochi (glutinous)" under several emvironmental conditions. Kernels obtained were germinated and the number of vascular bundles in their coleptiles were determined.

Development of Large Vascular Bundles in the Internode below the Neck of Panicle, and the Mode of Connection of Large Vascular Bundle in Primary Branch of Rice Plant

open access: yesJapanese Journal of Crop Science, 1977
An anatomical study was carried out on the development of large vascular bundles in the internode below the neck of panicle in rice plant, and on the mode of connection by vascular bundle between primary branch and secondary one or pedicel. Initial cells of the vascular bundles initiated at approximately the same time with differentiation of spikelet ...

Ultrastructural Analysis of the Digestive Gland Secretory and Absorptive Processes in Nepenthes glandulifera [PDF]

open access: yes, 2019
Nepenthes glandulifera is a carnivorous pitcher plant native to tropical environments, of which the majority live on the islands in the Malay Archipelago where sunlight and water are abundant.

Phloem loading in the sucrose-export-defective (SXD-1) mutant maize is limited by callose deposition at plasmodesmata in bundle sheath-vascular parenchyma interface [PDF]

open access: yes, 2000
Using Lucifer Yellow we have demonstrated that the phloem-loading pathway from the mesophyll to the bundle sheath-vascular parenchyma interface in Zea mays source leaves follows a symplasmic route in small and intermediate vascular bundles in control as ...
