The Effect of Calcium on Early Fiber Elongation in Cotton Ovule Culture
Cotton fiber developing on cultured ovules is an important experimental tool, even though in vitro grown fibers are shorter than in situ grown fibers. Fiber measurements and microscopy show that early fiber elongation increased when calcium concentration in the culture medium was reduced from the traditional 3 mM to 0.1 mM. Fiber length in 0.1 mM calcium responded negatively to trifuoperazine, ...
متن کاملCOTTON Relationships between Insufficient Potassium and Crop Maturity in Cotton
difficult to prove cause and effect for maturity differences being responsible for any variation in response Potassium deficiency in cotton (Gossypium hirsutum L.) depresses among genotypes to K. Theoretically, differences in root yield by decreasing late season growth and is reportedly more harmful to early maturing cotton genotypes. Research objectives were to detersystem size or effectivenes...
متن کاملThe calcium sensor GhCaM7 promotes cotton fiber elongation by modulating reactive oxygen species (ROS) production.
Fiber elongation is the key determinant of fiber quality and output in cotton (Gossypium hirsutum). Although expression profiling and functional genomics provide some data, the mechanism of fiber development is still not well understood. Here, a gene encoding a calcium sensor, GhCaM7, was isolated based on its high expression level relative to other GhCaMs in fiber cells at the fast elongation ...
متن کاملA Cotton Annexin Protein AnxGb6 Regulates Fiber Elongation through Its Interaction with Actin 1
Annexins are assumed to be involved in regulating cotton fiber elongation, but direct evidence remains to be presented. Here we cloned six Annexin genes (AnxGb) abundantly expressed in fiber from sea-island cotton (G. barbadense). qRT-PCR results indicated that all six G. barbadense annexin genes were expressed in elongating cotton fibers, while only the expression of AnxGb6 was cotton fiber-sp...
متن کاملFruiting Branch K+ Level Affects Cotton Fiber Elongation Through Osmoregulation
Potassium (K) deficiency in cotton plants results in reduced fiber length. As one of the primary osmotica, K(+) contributes to an increase in cell turgor pressure during fiber elongation. Therefore, it is hypothesized that fiber length is affected by K deficiency through an osmotic pathway, so in 2012 and 2013, an experiment was conducted to test this hypothesis by imposing three potassium supp...
