“…These characteristics usually are influenced by genotype and genotype × environment interactions [12]. Genotype × environment interactions often result into scale or rank shift of genotype overall performance [13,14]. Understanding impenetrable interactions among genotype (crop bio-system) system with the soil, the atmosphere and the environment that plants live in it is important in planning key frame decisions including cultivar selection, sustainable farm management, and economic planning [15,16].…”

A brief review is given of investigations on stress-induced alterations in the yield of different biochemical contents in wheat. Wheat is major cereal crop for fulfilling the calories demands of growing population. Alterations in the worldwide climate are predicted to have critical sentence for crop production. Abiotic stresses such as heat and drought are major abiotic stresses restraining crop production. Heat stress reduces wheat growth by upsetting various physiological and biochemical processes and the developmental stage of the plant is critical in demonstrating the vulnerability of various species and cultivars subjected to high temperature. Heat stress did not affect the protein content but there is strong correlation between leaf nitrogen content and grain protein content. Induction of HSPs seems to be the universal response and adaptation to temperature stress. The synthesis of HSPs is believed to play significant role either in preventing or minimizing the adverse effects of high temperature both at molecular and cellular levels. Wheat has the tendency to adopt diverse types of responses to temperature stress as well as a heat shock by developing thermo-tolerance for the enhancement of the grain quality and yield.

Canalization of Tomato Fruit Metabolism

et al. 2017

To explore the genetic robustness (canalization) of metabolism, we examined the levels of fruit metabolites in multiple harvests of a tomato introgression line (IL) population. The IL partitions the whole genome of the wild species Solanum pennellii in the background of the cultivated tomato (Solanum lycopersicum). We identified several metabolite quantitative trait loci that reduce variability for both primary and secondary metabolites, which we named canalization metabolite quantitative trait loci (cmQTL). We validated nine cmQTL using an independent population of backcross inbred lines, derived from the same parents, which allows increased resolution in mapping the QTL previously identified in the ILs. These cmQTL showed little overlap with QTL for the metabolite levels themselves. Moreover, the intervals they mapped to harbored few metabolism-associated genes, suggesting that the canalization of metabolism is largely controlled by regulatory genes.

Genotype x environmental interaction (GxE) can lead to differences in performance of genotypes over environments. GxE analysis can be used to analyze the stability of genotypes and the value of test locations. We developed an Rlanguage program (RGxE) that computes univariate stability statistics, descriptive statistics, pooled ANOVA, genotype F ratio across location and environment, cluster analysis for location, and location correlation with average location performance. Univariate stability statistics calculated are regression slope (b i ), deviation from regression (S 2 d ), Shukla's variance (σ i 2 ), S square Wricke's ecovalence (W i ), and Kang's yield stability (YS i ). RGxE is free and intended for use by scientists studying performance of polygenic or quantitative traits over multiple environments. In the present paper we provide the RGxE program and its components along with an example input data and outputs. Additionally, the RGxE program along with associated files is also available on GitHub at https://github.com/mahendra1/RGxE,
