| transcriptome profiling of two asparagus bean (vigna unguiculata subsp. sesquipedalis) cultivars differing in chilling tolerance under cold stress. | cowpea (v. unguiculata l. walp.) is an important tropical grain legume. asparagus bean (v. unguiculata ssp. sesquipedialis) is a distinctive subspecies of cowpea, which is considered one of the top ten asian vegetables. it can be adapted to a wide range of environmental stimuli such as drought and heat. nevertheless, it is an extremely cold-sensitive tropical species. improvement of chilling tolerance in asparagus bean may significantly increase its production and prolong its supply. however, ge ... | 0 | 26954786 |
| [peculiarities of circadian rhythms in plants from different geographical latitudes]. | 1 two species of plants (taraxacum arcticum and arnica angustifolia), collected in spitsbergen (geogr. latitude 76-80 degrees) exhibit endogenous circadian leaf movements but also movements with shorter periods. astragalus frigidus, a. alpinus and hedysarum hedysaroides, collected in arctic regions of continental europe, also show endogenous diurnal leaf movements. 2. in most of the species tested, there was no difference in the length of the free running periods of plants from arctic and centra ... | 1966 | 24557984 |
| variation of nicotinamide adenine dinucleotide phosphate level in bean hypocotyls in relation to o(2) concentration. | slices of hypocotyls from 3-day-old seedlings of vigna sesquipedalis (l.) fruwirth in the germination stage were incubated under various gaseous conditions. the nadp+nadph level in the hypocotyl slices changed with the oxygen tension. a high nadp+nadph level was observed under aerobic conditions and a low nadp+nadph level under anaerobic conditions.the 100 x nadh/nad+nadh ratio increased greatly under anaerobic conditions. in general a low nadp + nadph level corresponded with a high 100 x nadh/n ... | 1966 | 16656283 |
| modification of metabolic pattern by variation of nicotinamide adenine dinucleotide phosphate level. | the experiments were designed to get some information on the metabolism controlled by variation of the nadp level, which is known to change with the variation of environmental factors.the exogenous nadp added to the mitochondria prepared from vigna sesquipedalis cotyledons was associated with and/or penetrated into the mitochondria. the combined nadp served in the operation of the mitochondrial nadp-isocitric acid dehydrogenase.the variation of nadp level by exogenous nadp was observed to modify ... | 1969 | 16657076 |
| relative activities of nad- and nadp- isocritric dehydrogenases in bean mitochondria modified by glycerol or nadp. | mitochondria from cotyledons of vigna sesquipedalis (l.) fruwirth (starchy seed) showed no nad-isocitric dehydrogenase (nad-idh) activity by the methods which have been known to be useful for the detection of nad-idh in mitochondria of plants including castor bean and alaska pea. when the vigna cotyledon mitochondria were treated with glycerol, nad-idh activity appeared and nadp-isocitric dehydrogenase (nadp-idh) activity was inhibited. the inhibition of mitochondrial nadp-idh by glycerol was ov ... | 1969 | 4388200 |
| isolation of lectins of different specificities on a single affinity adsorbent. | affinity chromatography on sepharose-fetuin columns was used in a single step procedure to isolate the lectins concanavalin a, favin, phytohemagglutinin, wheat germ agglutinin, and limulus hemagglutinin. new lectins with unknown binding specificities were also purified by the same procedure from extracts of small california white beans, idaho red beans, and white pea beans. the purified lectins exhibited different cell surface mapping properties on erythrocytes, lymphocytes, and sperm cells. it ... | 1975 | 1165252 |
| fatty acid composition of rhizobium spp. | the fatty acid composition of 42 isolates belonging to the major plant affinity groups of rhizobium has been determined and found to vary reproducible with culture age. numerical taxonomic techniques applied to the 15 major fatty acid components of log-phase cultures of comparable physiological age showed that the rhizobia constitute a uniform group. however, two clusters comprising soybean-cowpea isolates and pea-bean isolates were evident. these observations, based on a simple analysis of only ... | 1979 | 427657 |
| effect of gamma irradiation on nutritional value of dry field beans (phaseolus vulgaris) for chicks. | the effect of gamma irradiation (60co) of different varieties and breeding lines of dry field beans (phaseolus vulgaris) on chick growth was determined using a chick growth assay in which the diet contained approximately 50% beans. total protein (n x 6.25) in beans was not changed appreciably by irradiation (21 mrad) but protein solubility in water was decreased. irradiation increased in vitro enzymatic digestibility of bean protein by pepsin and by a mixture of trypsin, chymotrypsin and peptida ... | 1979 | 448472 |
| inheritance of seed protein content and other agronomic characters in long bean (vigna sesquipedalis fruw.). | seven varieties of long bean, which included three local and four exotic, were crossed in a complete diallel. this was an attempt to study the inheritance of crude protein content, protein yield, flowering date, pod yield and yield components.both additive and non-additive gene effects were responsible for the genetic variation in the diallel population. however, dominance variance was more important than additive variance in crude protein content, number of pods per plant and number of seeds pe ... | 1980 | 24305859 |
| glycemic responses to foods: possible differences between insulin-dependent and noninsulin-dependent diabetics. | the effect on the blood glucose response of varying the amount (25 or 50 g) and type (bread or beans) of carbohydrate (ch2o) in test meals and of adding fat and protein was examined in a group of insulin dependent and noninsulin dependent diabetic volunteers. with noninsulin-dependent diabetics, the blood glucose area after a half bread portion was 48% that of the full bread meal (p less than 0.001). white pea beans (50 g ch2o) gave a blood glucose response of 41 +/- 5% (p less than 0.001) that ... | 1984 | 6496392 |
