Summary
Crops, as human being main sources of food and clothes, are often endured diverse biotic and abiotic stresses, such as high salinity, drought, insect and disease. The genetic locus and epigenetic components play importance roles in responding to these stresses in crops. Accumulating evidences indicated that the proteins belong to classic genetic pathways could interact with the proteins from epigenetic components, and form complicated crosstalk or molecular regulatory network during the response to environmental factors in plants. Therefore, identification and functional analysis by transgenic or CRISPR/Cas9 technology of key components are urgent got sustainable modern agriculture in the future.
This issue highlights recent advances in the field of resistance to stress (biotic and abiotic) in crops. The topics are diverse: the identification of key components (genetic locus, key genes, small moleculars, proteins, secondary metabolites, etc.) from different crop species to response stresses (salt, drought, heat, insect, disease, etc.) and their functional mechanisms, plant-pathogens interactions, and plant-environmental factors acting on these interactions.

Abstract Cyclophilin (CYP) plays an important role in plant response to stress, and
OsCYP2, one gene of cyclophlilin
family, is involved in auxin signal transduction and stress signaling in rice. However, the mechanism that
OsCYP2
is involved in rice response to low temperature is still unclear. We identified a new
OsCYP2 allelic mutant, lrl3,
with fewer lateral roots, and the differences in shoot height, primary root length and adventitious root length
increased with the growth process compared to the wild-type plant. Auxin signaling pathway was also affected
and became insensitive to gravity. The transgenic rice plants with over-expression of
OsCYP2 were…

Abstract Chrysanthemum morifolium Ramat is one of the four major cut flowers in the world. Pht1 family is focus on the
uptake and transport of phosphate in plants. In our previous studies,
CmPht1;2 overexpression line (Oe1) had
higher phosphate contents both in roots and shoots, and its root development was significantly enhanced than
wild type (WT) at low phosphorus conditions in chrysanthemum. Metabolomics analysis showed that several
metabolites had a change in pyruvate metabolism and tricarboxylic acid (TCA) cycle pathway. To explore the
gene difference expression and the change of metabolic pathway between
CmPht1;2-Oe1 and WT, we conducted
the transcriptome analysis.…

Abstract Abiotic stresses at different growth stages in the life of plants negatively affect yield productivity. Therefore,
plants, including
Amaranthus hypochondriacus, develop adaptive strategies to face the stresses and expand
functional diversification. In plants, the mitochondrial transcription termination factors (
mTERF) are essential
functions in regulation, and organelles (mitochondria and chloroplasts) control gene expression (OGE) under
several stress conditions. Based on the in-silico-wide genome and transcriptome analysis, twenty-four
mTERF
genes were detected in the main targeted mitochondria organelles clustered into three different main groups.
The chromosomal location and gene duplication analysis indicated one segmental and one tandem duplication
in the genome. The…

Abstract Castor (
Ricinus communis L.) is one of ten oil crops in the world and has complex inflorescence styles. Generally,
castor has three inflorescence types: single female inflorescence (SiFF), standard female inflorescence (StFF) and
bisexual inflorescence (BF). StFF is realized as a restorer line and as a maintainer line, which was applied to castor
hybrid breeding. However, the developmental mechanism of the three inflorescences is not clear. Therefore, we
used proteomic techniques to analyze different inflorescence styles. A total of 72 diferentially abundant protein
species (DAPs) were detected. These DAPs are primarily involved in carbon and energy metabolism and carbon

Abstract The zinc finger homeodomain (ZF-HD) genes belong to the homeobox gene family, playing critical roles in flower development and stress response. Despite their importance, however, to date there has been no genome-wide identification and characterization of the ZF-HD genes that are probably involved in stress responses in maize. In this study, 24 ZF-HD genes were identified, and their chromosomal locations, protein properties, duplication patterns, structures, conserved motifs and expression patterns were investigated. The results revealed that the ZF-HD genes are unevenly distributed on nine chromosomes and that most of these genes lack introns. Six and two ZF-HD genes have undergone…

Abstract Gibberellin 2-oxidases (
GA2ox) are important enzymes that maintain the balance of bioactive GAs in plants.
GA2ox genes have been identified and characterized in many plants, but these genes were not investigated in
Brassica napus. Here, we identified 31
GA2ox genes in
B. napus and 15 of these
BnaGA2ox genes were distributed in the A and C subgenomes. Subcellular localization predictions suggested that all

Abstract Drought is a major abiotic stress limiting agricultural crops production worldwide. In our study, we isolated a novel C2H2-type zinc finger protein gene
ZF2 from chickpea. ZF2 consisted of 232 amino acids with two QALGGH motifs in Cys2/His2 zinc finger domain. Transient expression analysis of ZF2:GFP fusion protein showed that ZF2 was a nuclear localized protein. In the yeast assay system, the full-length of ZF2 did not show transcriptional activation. Expression of
ZF2 gene was enhanced by treatments of several abiotic stresses and phytohormones. The promoter region of
ZF2 contained multiple stress- and hormone-related cis-elements. Overexpression of
ZF2 in Arabidopsis…
