| T1 |
0-139 |
Sentence |
denotes |
The DUET gene is necessary for chromosome organization and progression during male meiosis in Arabidopsis and encodes a PHD finger protein. |
| T2 |
140-259 |
Sentence |
denotes |
Progression through the meiotic cell cycle is an essential part of the developmental program of sporogenesis in plants. |
| T3 |
260-389 |
Sentence |
denotes |
The duet mutant of Arabidopsis was identified as a male sterile mutant that lacked pollen and underwent an aberrant male meiosis. |
| T4 |
390-479 |
Sentence |
denotes |
Male meiocyte division resulted in the formation of two cells instead of a normal tetrad. |
| T5 |
480-672 |
Sentence |
denotes |
In wild type, male meiosis extends across two successive bud positions in an inflorescence whereas in duet, meiotic stages covered three to five bud positions indicating defective progression. |
| T6 |
673-869 |
Sentence |
denotes |
Normal microspores were absent in the mutant and the products of the aberrant meiosis were uni- to tri-nucleate cells that later degenerated, resulting in anthers containing largely empty locules. |
| T7 |
870-1002 |
Sentence |
denotes |
Defects in male meiotic chromosome organization were observed starting from diplotene and extending to subsequent stages of meiosis. |
| T8 |
1003-1114 |
Sentence |
denotes |
There was an accumulation of meiotic structures at metaphase 1, suggesting an arrest in cell cycle progression. |
| T9 |
1115-1231 |
Sentence |
denotes |
Double mutant analysis revealed interaction with dyad, a mutation causing chromosome cohesion during female meiosis. |
| T10 |
1232-1378 |
Sentence |
denotes |
Cloning and molecular analysis of DUET indicated that it potentially encodes a PHD-finger protein and shows specific expression in male meiocytes. |
| T11 |
1379-1492 |
Sentence |
denotes |
Taken together these data suggest that DUET is required for male meiotic chromosome organization and progression. |
