The mean deltaD value of petiole water of Pterocarpus indicus Willd (deltaD = -9.0 +/- 2.5 per thousand, n = 3) was not significantly different from the mean value of stem water (-8.3 +/- 2.8 per thousand, n = 3). deltaD values of main vein water ranged from -11.1 to + 12.0 per thousand (n = 14) and increased along the main vein from petiole to the tip of leaves. Mesophyll water was highly enri...

The intracellular distribution of the neurotoxin 2,4-diaminobutyric acid (DABA) in mature leaves of the perennial legume Lathyrus sylvestris L. var ;Lathco' (flatpea) was determined using subcellular fractions from mesophyll protoplasts. Chloroplasts contained about 15% of the cellular DABA. At least 75% of the DABA was vacuolar, based on the assumptions that each protoplast contained a single ...

The electrical fusion technique of Zimmermann and Scheurich (1981 Planta 151: 26-32) has been used to fuse mesophyll protoplasts of Avena, Zea, Vigna, Petunia, and Amaranthus. Electrical fusion proves to be a simple, effective, and general fusion technique that can be controlled to form either dikaryons or large multinucleate fusion bodies. In addition, we show that Vigna mesophyll protoplasts ...

We isolated large quantities of mesophyll protoplasts from source and sink leaves of soybean plants and examined them for amino acid uptake. Accumulation of amino acids in isolated protoplasts was linear for at least 40 minutes. Uptake kinetics revealed the presence of both saturable and linear components. Increasing external pH decreases the uptake. The uncoupler, carbonyl cyanide p-trifluorom...

Species of Carlina corymbosa L.,Carthamus dentatus Vahl. and Picnomon acarna (L.) Cass. are belonging to Asteraceae family. The purpose the study is determine anatomical structures these species in same tribe compare features. Samples root, stem leaf e-ach were collected, fixed examined using a light micros-cope. In addition, some features measured. Secondary growth was observed root cross sect...

Abstract C4 plants, such as maize, strictly compartmentalize Rubisco to bundle sheath chloroplasts. The molecular basis for the restriction of from more abundant mesophyll chloroplasts is not fully understood. Mesophyll transcribe large subunit gene and, when normally quiescent transcription nuclear small family overcome by ectopic expression, still do accumulate measurable Rubisco. Here we sho...

Cystoliths are large outgrowths of cell wall material and calcium carbonate with a silicon-containing stalk found in the leaves, stems roots only handful plant families. Each cystolith is contained within called lithocyst. In lithocysts may be mesophyll or epidermis. A study by Koch et al. (2009) reported unique, indented features on surface superamphiphilic Ruellia devosiana ( Acanthaceae ) le...
