Maize protein quality is determined by the composition of its endosperm proteins, which are classified as nutritionally poor zeins (prolamin and prolamin-like) and nutritionally rich non-zeins (albumin, globulin, glutelin-like, and glutelin). Protein quality is considerably higher in opaque-2 mutants due to increased content of non-zeins over zeins. However, the opaque-2 endosperm is soft, which leads to poor agronomic performance and post-harvest infestation. Endosperm modification of opaque-2 had led to the development of Quality Protein Maize (QPM), which has higher protein quality along with hard kernel endosperm. The present study was planned to analyze the expression dynamics of different protein fractions in the endospem of developing maize kernel in normal, opaque-2 and QPM in response to the introgression of endosperm modifiers. Results revealed that albumin and globulin content decreases, whereas, prolamin, prolamin-like, glutelin-like, and glutelin content increases with kernel maturity. It has been observed that opaque-2 mutation affects protein expression at initial stages, whereas, the effect of endosperm modifiers was observed at the intermediate and later stages of kernel development. It has also been noted that prolamin, glutelin, and glutelin-like fractions can be used as quick markers for quality assessment for differentiating QPM varieties, even at the immature stage of kernel development. Overall, the present study implicates the role of different protein fractions in developing and utilizing nutritionally improved maize varieties.

“…Most corn is rainfed (86%) and grown on farms of less than 5 hectares by approximately 2.5 million farmers (Bellon et al., 2018; Cruz‐Delgado et al., 2008). Domestic corn consumption makes up 20.9% of Mexico's total expenditure on food and beverages (SAGARPA, 2017), with an average annual per capita consumption of 330.45 Kg, presenting an increase of 5.1% in the period from 2012 to 2017 (Martinez & Fernandez, 2019). Total corn consumption during 2019/2020 was 44,700,000 Mg, an increase of 2.3% compared to the previous year (USDA, 2019).…”

Ecological niche models of productive corn races under climate change scenarios in central‐eastern Mexico

Corn (Zea mays L.) is the basis of the Mexican diet. In this country, corn is produced by about 2.5 million small farmers and grown on 8.4 million hectares in rainfed agriculture. However, its production is not enough to meet demand. Climate change may negatively impact corn production, putting Mexico's food security at risk. The main goal of this work was to identify which corn races can find favorable environmental conditions in the future under climate change scenarios in the Sierra Madre Oriental. The Sierra Madre is a region highly vulnerable to climate change; in 2020, corn production was 5,785,561 Mg yr −1 of which 49.87% was from rainfed agriculture.These corn races could be proposed to replace others not tolerant to climate change, mainly at high altitudes. Potential distribution models were obtained for seven highly productive maize races. The projections were generated with the MaxLike algorithm using representative concentration pathways 4.5 and 8.5 scenarios to 2050 and 2070. In addition, general circulation models (CCSM4, GISS.E2-R, and MPI-ESM-LR) were used. Our results show that the Tabloncillo and Tuxpeño races could slightly increase their potential distribution in the future. Both corn races present the highest number of municipalities with adequate environmental conditions for their future presence. As a strategy for adaptation to climate change, it is proposed to replace or complement maize races in high-altitude areas with other tropical ones with greater tolerance to high temperatures, such as the Tuxpeño race. INTRODUCTIONClimate change represents a risk to agricultural production due to the negative impact it would have on yields and the loss of suitable conditions for growing cereal grains (

“…The first is related to producing and recovering alcohols and fatty acids from biomasses. Among the alcohols, ethanol is the most representative, and its production and purification are the most mature option [15][16][17]. As for short-chain fatty acids, besides the production through fermentation of different substrates, which has been largely investigated [18][19][20], the relevant purification often represents the bottleneck for their prompt exploitation [21][22][23].…”
