TCP transcription factor, BRANCH ANGLE DEFECTIVE 1 (BAD1), is required for normal tassel branch angle formation in maize.
In grass inflorescences, a structure called the "pulvinus" is found between the inflorescence main stem and lateral branches. The size of the pulvinus affects the angle of the lateral branches that emerge from the main axis and therefore has a large impact on inflorescence architecture. Through EMS mutagenesis we have identified three complementation groups of recessive mutants in maize having ...
متن کاملComplex genetic architecture underlies maize tassel domestication
Maize (Zea mays) tassels underwent profound morphological changes during maize domestication and improvement. Although a number of genes affecting maize inflorescence development have been identified, the genetic basis of the morphological changes in maize tassels since domestication is not well understood. Here, using a large population of 866 maize-teosinte BC2 S3 recombinant inbred lines gen...
متن کاملNumber Q : 1 without a language model
Cross-cultural studies suggest that access to a conventional language containing words that can be used for counting is essential to develop representations of large exact numbers. However, cultures that lack a conventional counting system typically differ from cultures that have such systems, not only in language but also in many other ways. As a result, it is difficult to isolate the effects ...
متن کاملUSE OF TASSEL-SEED (Ts-S) MAIZE FOR ASSIMILATE TRANSPORT STUDIES USING INTACT OR DETACHED TASSEL BRANCHES
The anatomy of normal maize (Zea mays L.) ears precludes easy access to the kernel pedicel tissue for in vivo assimilate transport experiments. We investigated the possibility of using the Tassel·seed (Ts·51 mutant of maize as a model system for studies of assimilate movement into developing maize kernels. Hypodermic needles (26 gauge, 9.5 mm long) inserted under the pedicel epidermis of intact...
متن کاملMaize SBP-box transcription factors unbranched2 and unbranched3 affect yield traits by regulating the rate of lateral primordia initiation.
The separation of male and female flowers in maize provides the potential for independent regulation of traits that affect crop productivity. For example, tassel branch number controls pollen abundance and length of shedding time, whereas ear row number directly affects kernel yield. Mutations in duplicate SBP-box transcription factor genes unbranched2 (ub2) and ub3 affect both of these yield t...
