Plants have evolved annual and perennial life forms as alternative strategies to adapt reproduction and survival to environmental constraints. In isolated situations, such as islands, woody perennials have evolved repeatedly from annual ancestors. Although the molecular basis of the rapid evolution of insular woodiness is unknown, the molecular difference between perennials and annuals might be rather small, and a change between these life strategies might not require major genetic innovations… 

Genetic regulation of flowering time in annual and perennial plants

TLDR
The current understanding in genetic regulation of the phase transition from vegetative to reproductive growth is discussed by using Arabidopsis as a model and how this knowledge has been successfully applied for identifying homologous genes from perennial crops is described.

Genetic control of meristem arrest and life span in Arabidopsis by a FRUITFULL-APETALA2 pathway

TLDR
A genetic pathway regulating GPA in Arabidopsis that responds to age-dependent factors and acts in parallel to seed-derived signals is uncovered, which negatively regulates expression of the meristem maintenance factor WUSCHEL in an AP2-dependent manner.

Genetic mapping of flowering time genes and functional characterisation of an FVE homologue from sugar beet

TLDR
The objectives of this project were to transfer, and expand, the knowledge of flowering time control to sugar beet, and identify several mutants that require vernalization to bolt and thus behave as biennials.

Comparative analysis of flowering in annual and perennial plants.

Epigenetic regulation of bud dormancy events in perennial plants

TLDR
The most relevant molecular and genomic contributions in the field of bud dormancy are revised, and the increasing evidence for chromatin modification involvement in the epigenetic regulation of seasonal dormancy cycles in perennial plants is discussed.

A suppressor of axillary meristem maturation promotes longevity in flowering plants

TLDR
Results indicate that AHL15 expression acts as a key molecular switch, directly downstream of flowering genes (SOC1, FUL) and upstream of GA biosynthesis, in extending the plant’s lifespan by suppressing AM maturation.

Stem anatomy supports Arabidopsis thaliana as a model for insular woodiness.

TLDR
It is evident that many missing pieces of this intriguing genetic puzzle leading to insular woodiness in eudicots need to be found before the authors can better understand one of the most fascinating developmental aspects of plants.

Innovation of a Regulatory Mechanism Modulating Semi-determinate Stem Growth through Artificial Selection in Soybean

TLDR
It is shown that semi-determinacy in soybean is modulated by transcriptional repression of Dt1, the functional ortholog of TFL1, in SAMs, which is further demonstrating the evolutionary novelty of the regulatory mechanism underlying stem growth in soy bean.

The Flowering Integrator FT Regulates SEPALLATA3 and FRUITFULL Accumulation in Arabidopsis Leavesw⃞

TLDR
It is proposed that FT functions through partner-dependent transcriptional activation of these and as-yet-unknown genes and that this occurs at several sites and that organ fate may depend on both degree of activation and the developmental stage reached by the organ before activation occurs.

Redundant regulation of meristem identity and plant architecture by FRUITFULL, APETALA1 and CAULIFLOWER.

TLDR
This work finds that mutations in the FRUITFULL (FUL) MADS-box gene, when combined with mutations in AP1 and CAL, lead to a dramatic non-flowering phenotype in which plants continuously elaborate leafy shoots in place of flowers.

A MADS domain gene involved in the transition to flowering in Arabidopsis.

TLDR
By transposon tagging, late flowering agl20 mutants are identified and it is shown that AGL20 is involved in flowering time control and integrates signals of different pathways of floral induction and might be a central component for the induction of flowering.

Distinct roles of CONSTANS target genes in reproductive development of Arabidopsis.

TLDR
Four early target genes of CO were identified using a steroid-inducible version of the protein to define common components of distinct flowering-time pathways.

The synergistic activation of FLOWERING LOCUS C by FRIGIDA and a new flowering gene AERIAL ROSETTE 1 underlies a novel morphology in Arabidopsis.

TLDR
Results demonstrate that modulation in flowering-time genes is one of the mechanisms leading to morphological novelties in plant macroevolution.

Flowering as a Condition for Xylem Expansion in Arabidopsis Hypocotyl and Root

The AGAMOUS-LIKE 20 MADS domain protein integrates floral inductive pathways in Arabidopsis.

TLDR
The results indicate that AGL20 is an important integrator of three pathways controlling flowering in Arabidopsis, and is positively regulated not only by the redundant vernalization and autonomous pathways of flowering but also by the photoperiod pathway.

Mechanisms and function of flower and inflorescence reversion.

TLDR
It is concluded that most species (including Arabidopsis) are less prone to reversion because signals from the leaf are less ephemeral, and the pathways driving flower development have a high level of redundancy that generates meristem autonomy even when leaf-derived signals are weak.
