Ovule abortion in Arabidopsis triggered by stress.
Environmental stresses frequently decrease plant fertility. In Arabidopsis, the effect of salt stress on reproduction was examined using plants grown in hydroponic medium. Salt stress inhibited microsporogenesis and stamen filament elongation. Because plants grown in hydroponic media can be rapidly and transiently stressed, the minimum inductive treatment to cause ovule abortion could be determ...
متن کاملRegulation of ovule development.
Ovule development in Arabidopsis and other plants has been the focus of classic and molecular genetic analyses in recent years. This has been an exciting time to be involved in plant developmental biology, because many genetic pathways and regulatory mechanisms have been elucidated. Continued studies of ovule mutants have contributed to and benefited from these advances. Ovule development invol...
متن کاملFunctional analysis of MADS-box genes controlling ovule development in Arabidopsis using the ethanol-inducible alc gene-expression system
In Arabidopsis, different combinations of ABC organ identity proteins interact in the presence of SEPALLATA (SEP) proteins to regulate floral organ differentiation. Ectopic expression of SEP3 in combination with class A and B or B and C genes is sufficient to homeotically convert vegetative leaves into petal-like organs and bracts into stamen-like structures, respectively. Recently, it has been...
متن کاملDissection of sexual organ ontogenesis: a genetic analysis of ovule development in Arabidopsis thaliana.
Understanding organogenesis remains a major challenge in biology. Specification, initiation, pattern formation and cellular morphogenesis, have to be integrated to generate the final three-dimensional architecture of a multicellular organ. To tackle this problem we have chosen the ovules of the flowering plant Arabidopsis thaliana as a model system. In a first step towards a functional analysis...
متن کاملSHORT INTEGUMENT (SIN1), a gene required for ovule development in Arabidopsis, also controls flowering time.
The short integument (sin1) mutation causes a female-specific infertility, and a defect in the control of time to flowering in Arabidopsis. Female sterility of Sin- plants is due to abnormal ovule integument development and aberrant differentiation of the megagametophyte in a subset of ovules. An additional defect of sin1 mutants is the production of an increased number of vegetative leaf and i...
