Taxon: maize ✕

A claim can belong to several research areas, so group counts add up to more than the total.

Taxon groups are the verbatim names found in the abstracts (case-insensitive), not normalised: maize, corn and Zea mays are separate groups here. The Organism view merges them through NCBI Taxonomy.

Organism groups follow NCBI Taxonomy: the spellings of one organism are merged, a claim naming several organisms sits in each group, and claims whose value names no organism are under “not stated”.

Title

Effects of Glucose Starvation on Mitochondrial Subpopulations in the Meristematic and Submeristematic Regions of Maize Root

Ivan Couée; Murielle Jan; Jean-Pierre Carde; et al. PLANT PHYSIOLOGY 1992. doi:10.1104/pp.100.4.1891

Other claims from this paper (10)

Observation Maize root-tip mitochondria were heterogeneous on Percoll density gradients.
Observation The mitochondrial ultrastructure was consistent with different maturation stages during cell development.
Observation Higher-density mitochondria had many cristae and a dense matrix.
Observation Higher-density mitochondria had classic respiratory properties but low ADP/O ratios.
Observation Lower-density mitochondria had few cristae and a clear matrix.
Observation Lower-density mitochondria respired slowly with weak respiratory control.
Intervention effect Higher-density mitochondria retained ultrastructure and most respiratory properties during glucose starvation.
Intervention effect Lower- and intermediate-density mitochondria were absent after glucose starvation.
Intervention effect Total mitochondrial protein per root tip decreased during glucose starvation.
Observation A significant functional mitochondrial pool remained in maize root tips during early glucose starvation.
