Precise somatic and reproductive cell proliferation and differentiation in anthers are crucial for male fertility. Loss of function of the Male sterile 8 (Ms8) gene causes male sterility with multiple phenotypic defects first visible in the...
SGO1 but not SGO2 is required for maintenance of centromere cohesion in Arabidopsis thaliana meiosis [0.03%]

Shugoshin is a protein conserved in eukaryotes and protects sister chromatid cohesion at centromeres in meiosis. In our study, we identified the homologs of SGO1 and SGO2 in Arabidopsis thaliana. We show that AtSGO1 is necessary for the mai...

The developmental plasticity of plants is beautifully illustrated by the competence of the immature male gametophyte to change its developmental fate from pollen to embryo development when exposed to stress treatments in culture. This proce...

While the question of why organisms reproduce sexually is still a matter of controversy, it is clear that the foundation of sexual reproduction is the formation of gametes with half the genomic DNA content of a somatic cell. This reduction ...

Seed is one of the key factors of crop productivity. Therefore, a comprehension of the mechanisms underlying seed formation in cultivated plants is crucial for the quantitative and qualitative progress of agricultural production. In angiosp...
Computational identification of conserved microRNAs and their putative targets in the Hypericum perforatum L. flower transcriptome [0.03%]

MicroRNAs (miRNAs) have recently emerged as important regulators of gene expression in plants. Many miRNA families and their targets have been extensively studied in model species and major crops. We have characterized mature miRNAs along w...
Parental genetic distance and patterns in nonrandom mating and seed yield in predominately selfing Arabidopsis thaliana [0.03%]
拟自我授粉的拟南芥中的非随机交配及其与亲本遗传距离和种子产量之间的关系

Ann L Carlson et al.
In this study, we ask two questions: (1) Is reproductive success independent of parental genetic distance in predominately selfing plants? (2) In the absence of early inbreeding depression, is there substantial maternal and/or paternal vari...

Microspore embryogenesis involves reprogramming of the pollen immature cell towards embryogenesis. We have identified and characterized a collection of 14 genes induced along different morphological phases of microspore-derived embryo devel...
