The little that we do know about the molecular mechanisms controlling follicle cell planar polarity and egg chamber elongation has largely come from work on mutations that produce round rather than elongated eggs.
These conditions necessarily promote frequent misfolding and aggregation of polypeptides [ 39], especially in regions of intense translation because elongating chains remain largely unfolded until synthesis of a whole protein domain is finished [ 40].
ANOVA showed highly significant variance among rice germplasm accessions, together with less or no significant variance between replications for ML in dark germination with water (MLw) and ML in sand culture (MLs) (Table 1).> As shown in Fig. 1, only a low proportion of germplasm accessions had largely elongated mesocotyl.
Instead, ostracod sperm consists of a large, elongate head.
Metamerism, or segmentation, a feature in the embryos of all vertebrates, remains preserved only in the adults of fishes and of terrestrial vertebrates that have elongated bodies (salamanders, snakes); it becomes largely erased in four-footed animals that depend on their limbs for locomotion.
During Xenopus gastrulation, the embryo elongates along an anterior-posterior (AP) axis, largely due to a cell movement called convergent extension (CE) in which cells are polarized and change their morphology to spindle-shape and intercalate each other [1] [3].
Previous ultrastructural studies have provided high-resolution snapshots, revealing coated and noncoated vesicles, membrane-contiguous vacuoles, elongated tubules and stacks of lumenless membrane disks with largely unknown functions [ 32- 36].
These "bundled" calcite crystals are consistently elongate along the c-axis, and their aspect ratios are largely >6.
Length of mandible: (0) short or moderately long, largely covered by labrum in repose; (1) very elongate and protruding in resting position.
Culm soluble sugars were located largely within the intracellular compartment of both ripening and elongating internodes.
The presence of FA (2 mM) slightly elongated the cell shape, and in parallel the cell number was largely reduced).
