Flowering

Flowering is a major developmental transition in plants, from the vegetative to the reproductive state, during which the plants structurally acquires reproductive competence by producing inflorescences. The timing of this change is influenced by endogenous and environmental signals such as hormones, day length and temperature.

    Seasonal control of flowering is a dramatic example of interactions between genes and environment, and is mostly studied in growth chambers. However, switching from natural settings to artificial conditions affects phenotypes. More natural responses in cabinets can be obtained by only modifying a few environmental parameters.

    Biennial plants require exposure to the cold of winter to overcome a block to flowering in the spring. The molecular role of FRIGIDA, a key component of the system that establishes the cold requirement in Arabidopsis, is to assemble a protein super-complex that promotes expression of a flowering repressor in the autumn.

    The stigma has a tightly regulated functional lifespan and is therefore a key determinant for floral receptivity. New evidence reveals how two transcription factors play a pivotal role in controlling stigma lifespan by regulating developmental programmed cell death in this tissue to terminate pollen receptivity.

    The time of flowering is important in crop production. Rice has now been genetically engineered to respond to agrochemical spraying, which results in floral induction. This research offers new perspectives to control the phenological development of crops in the field.

    Florigen plant hormone is made in the leaf and then travels to the shoot apical meristem to trigger flowering. The phloem-mobile metal-binding protein NaKR1 physically interacts with florigen and mediates its long-distance transport through the sieve element.

    Angiosperm evolution involves a major transition from spiral to whorled arrangements of floral organs. Examination of the genetic programs specifying floral organ identity in Nigella damascene, a species of Ranunculaceae with spiral flowers, illuminates the molecular basis of how spiral flowers can have flexible numbers of floral organs.
