Abstract In arid and semi-arid sand dune ecosystems, belowground bud bank plays an important role in population regeneration and vegetation restoration. However, the responses of belowground bud bank size and composition to
sand burial and its induced changes in soil environmental factors have been rarely studied. In arid sand dunes
of Northwestern China, we investigated belowground bud bank size and composition of the typical rhizomatous
psammophyte Psammochloa villosa as well as three key soil environmental factors (soil moisture, total carbon and
total nitrogen) under different depths of sand burial. Total buds and rhizome buds increased significantly with
increasing burial depth, whereas… More >

Abstract Leaf is a vital organ of plants that plays an essential role in photosynthesis and respiration. As an important agronomic trait in leaf development, leaf shape is classified into lobed, entire (no-lobed), and serrated in most crops. In this study, two-lobed leaf watermelon inbred lines WT2 and WCZ, and a no-lobed leaf watermelon inbred line WT20 were used to create two F2 populations. Segregation analysis suggested that lobed leaves were dominant over the no-lobed leaves, and it was controlled by a signal gene. A locus on watermelon chromosome 4 controlling watermelon lobed/no-lobed leaves was identified through BSA-seq strategy combined with… More >

Abstract
The rapidly growing world population, water shortage, and food security are promising problems for sustainable agriculture. Farmers adopt higher irrigation and fertilizer applications to increase crop production resulting in environmental pollution. This study aimed to identify the long-term effects of intelligent water and fertilizers used in corn yield and soil nutrient status. A series of field experiments were conducted for six years with treatments as: farmer accustomed to fertilization used as control (CON), fertilizer decrement (KF), fertilizer decrement + water-saving irrigation (BMP1); combined application of organic and inorganic fertilizer + water-saving irrigation (BMP2), and combined application of controlled-release fertilizer (BMP3).… More >

Abstract Abiotic stresses are among the major limiting factors for plant growth and crop productivity. Among these, salinity is one of the major risk factors for plant growth and development in arid to semi-arid regions. Cultivation of salt tolerant crop genotypes is one of the imperative approaches to meet the food demand for increasing population. The current experiment was carried out to access the performance of different rice genotypes under salinity stress and Zinc (Zn) sources. Four rice genotypes were grown in a pot experiment and were exposed to salinity stress (7 dS m−1), and Zn (15 mg kg−1 soil) was… More >

Abstract The phytoene desaturase (PDS) encodes a crucial enzyme in the carotenoid biosynthesis pathway. Silencing or inhibiting PDS expression leads to the appearance of mottled, chlorosis, or albino leaves. In this study, the CDS sequence of EuPDS (Eucommia ulmoides Phytoene Desaturase) was first cloned and then PDS was silenced in Nicotiana benthamiana. Result showed the expression level of EuPDS in leaves was higher than that in the roots and stems. In N. benthamiana leaves, which were treated by Agrobacterium for 24 h, photo-bleaching was shown on the fresh leaves one week after injection and the transcript level of PDS was down-regulated… More >

Abstract Although Platycodon grandiflorum (Jacq.) A.DC. is a renowned medicine food homology plant, reports of excessive cadmium (Cd) levels are common, which affects its safety for clinical use and food consumption. To enable its Cd levels to be regulated or reduced, it is necessary to first elucidate the mechanism of Cd uptake and accumulation in the plant, in addition to its detoxification mechanisms. This present study used inductively couple plasma-mass-spectrometry to analyze the subcellular distribution and chemical forms of Cd in different tissues of P. grandiflorum. The experimental results showed that Cd was mainly accumulated in the roots [predominantly in the… More >

Abstract Drought is one of the major abiotic threat to rice production in the context of climate change. Super Basmati is an
elite, fine grain basmati rice variety grown in Punjab, Pakistan. Due to drought sensitive in nature, its yield has
been facing an alarming situation in production because of gradual decrease in irrigated water for a couple of
years. Three reported novel QTLs for drought tolerance were selected for incorporation into Super Basmati by
employing marker assisted selection strategy. IR55419-04 with novel QTLs was used as a donor parent. Foreground selection was performed by applying PCR based QTL linked SSR… More >

Abstract Phytocyanin (PC) is a class of plant-specific blue copper proteins involved in electron transport, plant growth, development, and stress resistance. However, PC proteins have not been systematically evaluated in tobacco plants. We determined the whole-genome sequences of the PC family in the tobacco cultivar ‘K326.’ The transcriptome data were used to analyze the expression of the NtPC family at different development stages and tissue-specific genes. Real-time fluorescence quantitative analysis was used to analyze the expression of the NtPC gene family under low temperature and methyl jasmonate stress. The tobacco NtPC family contained 110 members and was divided into four subfamilies:… More >

Abstract Salinity is one of the major constraints reducing plant growth and yield. Irrigation with poor quality and brackish water to orchards is a major cause of stunted growth and low yield. The salt tolerance mechanism is one of the complicated genomic characters that is very problematic to develop in fruit trees and becomes much more severe at any growth and developmental stage. Osmotic stress and hormonal imbalances are major constraints causing low biomass production. Fruit tree tolerance/sensitivity is chiefly based on the activation of a defense system comprised of super-oxidase dismutase (SOD), peroxidase (POD) and catalases (CAT), non-enzymatic compounds including… More >

Abstract
The increasing world population has forced excessive chemical fertilizer and irrigation to complete the global food demand, deteriorating the water quality and nutrient losses. Short-term studies do not compile the evidences; therefore, the study aimed to identify the effectiveness of reduced doses of inorganic fertilizer and water-saving practices, hence, a six-year experiment (2015–2020) was conducted in China to address the knowledge gap. The experimental treatments were: farmer accustomed fertilization used as control (525:180:30 kg NPK ha−1), fertilizer decrement (450:150:15 kg NPK ha−1), fertilizer decrement + water-saving irrigation (450:150:15 kg NPK ha−1), application of organic and inorganic fertilizer + water-saving irrigation… More >

Abstract Drought stress is a serious threat to the germination of plant seeds and the growth of seedlings. Melatonin has been proven to play an important role in alleviating plant stress. However, its effect on seed germination under drought conditions is still poorly understood. Therefore, we studied the effects of melatonin on rice seed germination and physiological characteristics under drought stress. Rice seeds were treated with different concentrations of melatonin (i.e., 0, 20, 100, and 500 μM) and drought stress was simulated with 5% polyethylene glycol 6000 (PEG6000). The results showed that 100 μM melatonin can effectively improve the germination potential,… More >

Abstract Environmental conditions of a parent plant can influence the performance of their clonal offspring, and such clonal transgenerational effects may help offspring adapt to different environments. However, it is still unclear how many vegetative generations clonal transgenerational effects can transmit for and whether it depends on the environmental conditions of the offspring. We grew the ancestor ramets of the floating clonal plant Spirodela polyrhiza under a high and a low nutrient level and obtained the so-called 1st-generation offspring ramets of two types (from these two environments). Then we grew the 1st-generation offspring ramets of each type under the high and… More >

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 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… More >
