Abstract:
... The primary objective of this study was to determine how various crop species differ in their cation-anion balance and thus in their effects on soil reaction and on the acidifying effects of N fertilizers on the base status of soils. Samples of 27 species of cereal, grass, legume, and miscellaneous field and vegetable crops were collected from a wide range of environmental conditions in the field. ...

Abstract:
... The auxin-like properties of 4-amino-3,5,6-trichloropicolinic acid (picloram) were compared with those of other auxins in tissue cultures of wheat (Triticum aestivum), soybeans (Glycine max), tobacco (Nicotiana tabacum), and jackbean (Canavalia ensiformis) explants. Certain problems associated with the use of 2,4-dichlorophenoxyacetic acid (2,4-D) in tissue culture were not encountered when piclor ...

Abstract:
... In eubacterial and eukaryotic tRNAs specific for Asn, Asp, His and Tyr the modified deazaguanosine-derivative queuosine occurs in position 34, the first position of the anticodon. Analysis of unfractionated tRNAs from wheat and from tobacco leaves shows that these tRNAs contain high amounts of guanosine (G) in place of queuosine (Q). This was measured by the exchange of G34 for [3H]guanine catalys ...

Abstract:
... A radiogasometric method for the determination of the rates of intracellular decarboxylation of primary and end products of steady-state photosynthesis in the light has been worked out. On the basis of oxygen dependence of the CO2 evolution, two types of decarboxylation, oxygenase (photorespiration) and oxidase (dark respiration), have been distinguished. Oxygenase decarboxylation is linearly depe ...

Abstract:
... Two different methods were used to investigate the abundance of cytosine methylation at the outer (5') position in 5'-CCG-3' trinucleotides in angiosperm genomes. MspI is unable to cut its target site if the outer cytosine is methylated (5'-mCCGG-3'). Using MspI restriction analysis, it was shown that 5'-mCCG-3' is present in all angiosperm genomes examined, and that the amount of cytosine methyla ...

Abstract:
... We investigated the role of actin microfilaments in nonhost resistance of higher plants. Here we present several lines of evidence to indicate that microfilaments are indeed involved in blocking fungal penetration of nonhost plants. Erysiphe pisi, a pathogen of pea, normally fails to penetrate into nonhost plants such as barley, wheat, cucumber and tobacco. When tissues of these nonhost plants wer ...

Abstract:
... The importance of the two chiral centers at C-3 and C-7 in the molecular structure of jasmonic acid in plant responses was investigated. We separated methyl jasmonate (MeJA) into (3R)- and (3S)-isomers with a fixed stereochemistry at C-3, but epimerization at C-7 is possible. The four isomers of the nonepimerizable analog 7-methyl MeJA were synthesized. These six esters and their corresponding aci ...

The mutant forms of the protein were modified by th ...

Abstract:
... Transcription of Cab genes has been previously shown to be regulated by a circadian oscillator coupled to the red light-absorbing plant photoreceptor phytochrome in various plant species. In addition, it has recently been suggested that rhythmic expression of the Cab genes could also be affected by a phytochrome-independent circadian oscillator in a developmentally regulated fashion. This study ha ...

Abstract:
... A comparison of the wild-type firefly luciferase reporter gene to a codon-modified gene, available from Promega, demonstrates that in tobacco cell cultures, an increase in G+C content of 1.8%, as a consequence of 36 A/T leads to G/C synonymous codon alterations and removal of the lysosomal targeting sequence, has no significant effect on expression. In maize Black Mexican Sweet cells and wheat scu ...

Abstract:
... Although cytokinins (CKs) affect a number of processes connected with chloroplasts, it has never been rigorously proven that chloroplasts contain CKs. We isolated intact chloroplasts from tobacco (Nicotiana tabacum L. cvSR1) and wheat (Triticum aestivum L. cv Ritmo) leaves and determined their CKs by liquid chromatography/tandem mass spectroscopy. Chloroplasts from both species contained a whole s ...

Very little is known about the molecular biology of its gametophyte development despite a longstanding interest in hybrid seeds. We present here a comprehensive characterization of three apparently homeologous genes (TAA1a, TAA1b and TA ...

Abstract:
... The major constraint to plant growth in acid soils is the presence of toxic aluminum (Al) cations, which inhibit root elongation. The enhanced Al tolerance exhibited by some cultivars of wheat is associated with the Al-dependent efflux of malate from root apices. Malate forms a stable complex with Al that is harmless to plants and, therefore, this efflux of malate forms the basis of a hypothesis t ...
