    مصطلحات موضوعية: 0106 biological sciences, Infertilité mâle, the mutant pollen was unable to compete successfully against wild-type pollen.

We characterized hxk5-1, F60 - Physiologie et biochimie végétale, Oryza sativa, Biology, rather than its role in sugar sensing and signaling. Our results demonstrate that OsHXK5 contributes to a large portion of the hexokinase activity necessary for the starch utilization pathway during pollen germination and tube growth, Germination du pollen, 03 medical and health sciences, a Tos17 mutant of OsHXK5 that is up-regulated in maturing pollen, medicine, otorhinolaryngologic diseases, [SDV.BV]Life Sciences [q-bio]/Vegetal Biology, indicating that its catalytic function was responsible for pollen fertility, although they were sufficient to produce some viable seed. However, 030304 developmental biology, a stage when starch accumulates. Progeny analysis of self-pollinated heterozygotes of hxk5-1 and reciprocal crosses between the wild-type and heterozygotes revealed that loss of HXK5 causes male sterility. Homozygous hxk5-1, Base Sequence, hxk5-3 and hxk5-4 lines created by CRISPR/Cas9 confirmed the male-sterile phenotype. In vitro pollen germination ability and in vivo pollen tube growth rate were significantly reduced in the hxk5 mutant pollen. Biochemical analysis of anthers with the mutant pollen revealed significantly reduced hexokinase activity and starch content, Oryza, Fertility, chemistry, as well as for starch biosynthesis during pollen maturation, 010606 plant biology & botany
