Functional genomics of plant compensatory responses
… lines developed from a cross between Columbia X Landsberg erecta, of the annual plant Arabidopsis thaliana were screened initially to identify QTLs. A total of three QTL located on chromosomes 1, 4 and 5 explaining 48.2% of the variation in fitness compensation were found. The microarray …

The adaptive potential of plant endopolyploidy in response to herbivory
… controls, while clipped plants of A. thaliana Landsberg erecta, a genotype that typically undercompensates, displayed an equal number of siliques but lower total seed yield than unclipped controls. Columbia-4’s overcompensation in fitness measures correlated with an overall increase in nuclear …

Dissecting Transcriptional Regulation of Rpp8 in Arabidopsis thaliana
… shows that RPP8 alleles from the Columbia and Landsberg erecta ecotypes are upregulated by H. parasitica and the defense signaling molecule salicylic acid, suggesting a potential feedback loop. RPP8-Ler is also systemically upregulated after infection of the bacterial pathogen Pseudomonas …

Effect of the parental environment on Arabidopsis thaliana seed quality
… Primeiro, sementes de genótipo do tipo selvagem Landsberg erecta foram produzidas em sete diferentes concentrações de fosfato (0, 12.5, 50, 500, 2500, 5000 e 50000 μM) a fim de determinar a mais efetiva concentração de fosfato para a produção de sementes. Após esse experimento, as sementes de …

A physiological and genetic analysis of the role of phytochrome in photoperiodic induction of flowering in Arabidopsis Thaliana
… of flowering in Arabidopsis thaliana (L.) Heyne, Landsberg erecta ecotype, was carried out. This revealed that 4 day old seedlings, at which time the cotyledons where expanding and greening, could differentiate between a LD and a SD. At this stage the critical daylength was between 8 and 10 hours. …

The AtMRS2 gene family from Arabidopsis thaliana
… have been cloned from cDNA (A. thaliana ecotype Landsberg erecta) and sequenced. Protein sequence similarity suggests that the family forms a sub-section of the CorA super-family of Mg2+ transport proteins. The mutant yeast used to identify the family initially was also used to show that two …

The spatial and temporal regulation of the transcriptome during plant development
… Arabidopsis thaliana accessions, Columbia and Landsberg erecta, were crossed reciprocally to produce hybrids. The small RNA expression patterns of both parents and two hybrids were compared. We find that the most common expression patterns for small RNAs in hybrid Arabidopsis are dominance for …
