Abstract Background Common bean ( Phaseolus vulgaris L.) is an important legume species which can be consumed as immature pods and dry seeds after re-hydration cooking. Many genes QTL, epistatic interactions among them, condition pod morphological traits. However, not all them have been mapped or validated nor candidate proposed. We sought to investigate the genomic regions conditioning color c...

Most soybean cultivars possess broad leaflets; however, a recessive allele on the Ln locus is known to cause the alteration of broad to narrow leaflets. The recessive allele ln has also been considered to increase the number of seeds per pod (NSP) and has the potential to improve yield. Recently, Gm-JAG1 (Glyma20g25000), a gene controlling Ln, has been shown to complement leaf shape and silique...

Oilseed rape (Brassica napus) is sexually compatible with its wild and weedy relative B. rapa, and introgression of genes from B. napus has been found to occur over a few generations. We simulated the early stages of transgene escape by producing F1 hybrids and the first backcross generation between two lines of transgenic B. napus and two populations of weedy B. rapa. Transgene expression and ...

Genes transformed into plants are usually inherited in a regular Mendelian manner. There are, however, transformants in which the selectable trait fails to segregate as expected. Genetic analysis of the kanamycin-resistance (KanR) trait in >900 independent transformants of Arabidopsis revealed that 9% produced progeny families with an enormous deficiency of KanR individuals. Self-pollination of...

The accumulation kinetics of 18 mRNAs were characterized during Arabidopsis silique development. These marker mRNAs could be grouped in distinct classes according to their coordinate temporal expression in the wild type and provided a basis for further characterization of the corresponding regulatory pathways. The abscisic acid (ABA)-insensitive abi3-4 mutation modified the expression pattern o...

Hormone patterns tailor cell fate decisions during plant organ formation. Among them, auxins and cytokinins are critical phytohormones early development. Nitric oxide (NO) modulates root architecture by the control of auxin spatial patterns. However, NO involvement coordination shoot organogenesis remains unclear. Here, we explore effect development using a phenotypic, cellular, genetic analysi...
