The stamens and lodicules, their role fulfilled, die and shrivel, and further growth and development takes place in the carpels, the developing grains.
From developing grains, around 540 miRNAs putatively associated with grain development were identified [ 31].
As a monocarpic plant, wheat development is characterized by a rapid translocation of metabolites from leaves to developing grains after anthesis.
Left, expression profiles of SWEET11a and SWEET11b as determined by quantitative real-time PCR (qPCR) on total RNA isolated from micro-dissected developing grains.
Changes of the concentrations of K, Ca and Mg in the developing grains, measured five times during grain filling as affected by elevated [CO2] and soil warming are shown in Fig. 3. Elevated [CO2] significantly decreased K concentration in the developing grains on 17 and 31 DAA and the mature grains.
Elevated [CO2] significantly decreased Ca concentration in the developing grains from 23 DAA onwards, whereas the decrease in Ca concentration caused by soil warming was not significant during grain filling.
In the developing grains, in relation to the AN treatment, only Mg concentration was significantly lowered by soil warming since 24 DAA; while the concentrations of K and Ca were identical between the two treatments.
SEM analysis was run using three biological replicates with at least four technical repetitions of developing grains per replication of the mounted specimens.
In this regard, understanding the functional and biochemical characteristics of the genes and gene products involved in PA biosynthesis in developing grains is essential.
Developing grains of all the four cultivars were collected 8 days after anthesis to assess the expression of TaCKX6-D1, TandpA6 and TaSSIIA genes.
SUS3 and SUS4 are expressed predominantly in developing grains, indicating potential roles in carbon allocation in filling grains (Hirose et al. 2008).
