miR319a targeting of TCP4 is critical for petal growth and development in Arabidopsis.
In a genetic screen in a drnl-2 background, we isolated a loss-of-function allele in miR319a (miR319a(129)). Previously, miR319a has been postulated to play a role in leaf development based on the dramatic curled-leaf phenotype of plants that ectopically express miR319a (jaw-D). miR319a(129) mutants exhibit defects in petal and stamen development; petals are narrow and short, and stamens exhibi...
متن کاملDevelopment of Safflower Petal Collector
Safflower [Carthamus tinctorius (L.)] is a multipurpose oilseed crop grown mainly for getting high quality edible oil rich in polyunsaturated fatty acids. India is the largest producer of safflower in the world with 402,000 hectares area under it, producing about 206,000 tons of safflower seed annually [1]. But its use in India is limited mainly to oil extraction from seed and leftover cake as ...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...

A recent study of the expression of floral organ identity genes in buttercups, poppies and their relatives has shed light on the evolutionary origin of petals.
متن کاملRABBIT EARS regulates the transcription of TCP4 during petal development in Arabidopsis
Plant organ growth requires the proper transition from cell proliferation to cell expansion and differentiation. The CIN-TCP transcription factor gene TCP4 and its post-transcriptional regulator microRNA319 play a pivotal role in this process. In this study, we identified a pathway in which the product of the C2H2 zinc finger gene RABBIT EARS (RBE) regulates the transcription of TCP4 during Ara...
