Hypoxic Induction of Anoxia Tolerance in Root Tips of Zea mays.
When root tips of fully aerobic, intact maize (Zea mays L.) seedlings are made anaerobic, viability normally is only 24 hours or less at 25 degrees C. We find that viability can be extended to at least 96 hours if seedlings are given a hypoxic pretreatment for 18 hours by sparging the solution with 4% O(2) in nitrogen (v/v) before anoxia. Fully aerobic root tips (sparged with 40% O(2)) had very...
متن کاملCytogenetics of Hybrids between Zea Mays and Euchlaena Mexicana.
NDOUBTEDLY specific and generic as well as lesser differences may U be largely attributed to differences in the chromosomes. Detailed analysis of gene and chromosome differences between related genera is seldom possible because of sterility and lack of genetical or cytological information. A striking exception is provided by Zea mays L. and Euchlaena mexicana Schrad. Between these distinct spec...
متن کاملPatterns of incorporation of (3H)galactose by cells of Zea mays root tips.
['H]galactose shows a selective pattern of uptake distribution in the apical portion of the root tip of Zea mays. In cells entering division it is incorporated into the Golgi apparatus within 10 min and is transferred from that organelle to the forming cell plate. The pattern of uptake suggests a specific biochemical activity on the part of the Golgi apparatus at the time of division so far as ...
متن کاملFlooding tolerance in interspecific introgression lines containing chromosome segments from teosinte (Zea nicaraguensis) in maize (Zea mays subsp. mays).
BACKGROUND AND AIMS Nicaraguan teosinte (Zea nicaraguensis), a species found in frequently flooded areas, provides useful germplasm for breeding flooding-tolerant maize (Z. mays subsp. mays). The objective of this study was to select flooding-tolerant lines using a library of introgression lines (ILs), each containing a chromosome segment from Z. nicaraguensis in the maize inbred line Mi29. M...
متن کاملSome physical properties of teosinte (Zea mays subsp. parviglumis) pollen.
In parts of the world where teosinte and maize are grown in close proximity, there is concern about gene flow between them. Pollen is the primary vehicle for gene flow. Quantifying the biophysical properties of pollen, such as its settling speed and dehydration rate, is important for evaluating outcrossing potential. These properties were measured for teosinte (Zea mays subsp. parviglumis) poll...
