| identification and origin of xanthomonas campestris pv. campestris races and related pathovars. | abstract one hundred sixty-four isolates of xanthomonas campestris pv. campestris and other x. campestris pathovars known to infect cruciferous hosts (x. campestris pvs. aberrans, raphani, armoraciae, and incanae) were inoculated onto a differential series of brassica spp. to determine both pathogenicity to brassicas and race. of these, 144 isolates were identified as x. campestris pv. campestris and grouped into six races, with races 1 (62%) and 4 (32%) being predominant. other races were rare. ... | 2001 | 18943594 |

| a comparison of leaf and petal senescence in wallflower reveals common and distinct patterns of gene expression and physiology. | petals and leaves share common evolutionary origins but perform very different functions. however, few studies have compared leaf and petal senescence within the same species. wallflower (erysimum linifolium), an ornamental species closely related to arabidopsis (arabidopsis thaliana), provide a good species in which to study these processes. physiological parameters were used to define stages of development and senescence in leaves and petals and to align these stages in the two organs. treatme ... | 2008 | 18539778 |
| glycogen synthase kinase-3 as drug target: from wallflower to center of attention. | some 20 years ago, glycogen synthase kinase-3 (gsk-3) was categorized as one of several protein kinases that could phosphorylate glycogen synthase and regulate the glucose metabolism pathway. today, gsk-3 is being identified as a ubiquitous serine/threonine protein kinase that participates in a multitude of cellular processes, ranging from cell membrane-to-nucleus signaling, gene transcription, translation, cytoskeletal organization to cell cycle progression and survival. two functional aspects ... | 2003 | 14702136 |
| acylated cyanidin 3-sambubioside-5-glucosides in three garden plants of the cruciferae. | seven acylated cyanidin 3-sambubioside-5-glucosides were isolated from the flowers of three garden plants in the cruciferae. specifically, four pigments were isolated from lobularia maritima (l.) desv., together with a known pigment, as well as, three pigments from lunaria annua l., and two known pigments from cheiranthus cheiri l. these pigments were determined to be cyanidin 3-o-[2-o-((acyl-ii)-(beta-d-xylopyranosyl))-6-o-(acyl-i)-beta-d-glucopyranoside]-5-o-[6-o-(acyl-iii)-beta-d-glucopyranos ... | 2006 | 16777160 |
| sexual selection when fertilization is not guaranteed. | much of the theory of sexual selection assumes that females do not generally experience difficulties getting their eggs fertilized, yet sperm limitation is occasionally documented. how often does male limitation form a selection for female traits that improve their mating rate? the question is difficult to test, because if such traits evolve to be efficient, sperm limitation will no longer appear to be a problem to females. here, we suggest that changes in choosiness between populations, and in ... | 2005 | 16261726 |

| female condom: a market wallflower. | overseas sales of the female condom are growing, as groups like the united nations aids programs encourage their use by millions of women in parts of africa. the reality condom, the only female condom on the market in the united states since 1993, has not experienced widespread use within the u.s. sales in the u.s. are thought to be lagging because potential users are uncomfortable with the look, squeaky sound, and insertion of this condom. | 1999 | 11367176 |

| preferential partner selection in an evolutionary study of prisoner's dilemma. | partner selection is an important process in many social interactions, permitting individuals to decrease the risks associated with cooperation. in large populations, defectors may escape punishment by roving from partner to partner, but defectors in smaller populations risk social isolation. we investigate these possibilities for an evolutionary prisoner's dilemma in which agents use expected payoffs to choose and refuse partners. in comparison to random or round-robin partner matching, we find ... | 1996 | 8924642 |
