Complex 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 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 کاملTransport of boron by the tassel-less1 aquaporin is critical for vegetative and reproductive development in maize.
The element boron (B) is an essential plant micronutrient, and B deficiency results in significant crop losses worldwide. The maize (Zea mays) tassel-less1 (tls1) mutant has defects in vegetative and inflorescence development, comparable to the effects of B deficiency. Positional cloning revealed that tls1 encodes a protein in the aquaporin family co-orthologous to known B channel proteins in o...
متن کاملThe interaction of knotted1 and thick tassel dwarf1 in vegetative and reproductive meristems of maize.
In Arabidopsis, SHOOT MERISTEMLESS (STM) and CLAVATA1 (CLV1) competitively regulate meristem homeostasis. Here, we explore the interaction of their maize homologs knotted1 (kn1) and thick tassel dwarf1 (td1). kn1 mutants form fewer lateral organs and td1 inflorescences are fasciated with additional floral organs. Double mutants show kn1 epistatic to td1 in seedling and ear development but dose-...
متن کاملPlant factors controlling seed set in maize : the influence of silk, pollen, and ear-leaf water status and tassel heat treatment at pollination.
In maize (Zea mays L.) large decreases in kernel number result when low water potentials (Psi(w)) and high temperatures occur during pollination. To gain insight into the basis for the decreased seed set, silk, pollen, and ear-leaf Psi(w), the capability for silk osmotic adjustment, and pollen appearance were measured to determine their relationship to seed set. A multiple-eared or prolific (hi...
