The chloroplast NAD(P)H dehydrogenase (NDH) complex is involved in photosystem I (PSI) cyclic electron transport (CEF). The enhancement of NDH-dependent CEF can facilitate the alleviation of the damage to the photosynthetic apparatus. The NdhB subunit encoded by chloroplast genome is one of the most important subunits of NDH complex. Fu et al. found a novel thylakoid transit peptide of NdhB subunit in S111-9. It may contribute to facilitating the expression and localization of NdhB subunit.

Abstract Medicinal herbs are well known and studied over the past millennia in most of the developing countries as a rational means of treatment against various diseases and disorders. Wedelolactone (WDL), a major bioactive compound in Eclipta prostrata L (Eclipta alba L), has been reported with potential benefits in human health against chronic diseases. However, a comprehensive study on WDL pharmacological benefits in various ailments, to the best of our knowledge, is not yet reported. Thereof, the present review provides the recent therapeutic applications in reference to biological and functional activities against major human chronic diseases, including cardiovascular, cancer, diabetes mellitus,… More >

Abstract Selection and use of molecular markers for evaluation of DNA polymorphism in plants are couple of the most important approaches in the field of molecular genetics. The assessment of genetic diversity using morphological markers is not sufficient due to little differentiating traits among the species, genera or their individuals. Morphological markers are not only highly influenced by environmental factors but skilled assessment is also prerequisite to find the variations in plant genetic resources. Therefore, molecular markers are considered as efficient tools for detailed DNA based characterization of fruit crops. Molecular markers provide new directions to the efforts of plant breeders… More >

Abstract Heavy metal-contaminated soil is one of the major environmental
pollution problems of agricultural production and human health in the world.
Remediation of heavy metals in soil is one of the most popular research subjects.
Different remediation strategies have been reported to remove heavy metals from
contaminated soil, among which phytoremediation is the most important one.
Compared with other major crops, cotton shows the strongest and most widespread resistance to abiotic stresses, such as heavy metals. Although heavy metal
stress adversely affects the growth and development of cotton, cotton possesses a
set of sophisticated stress-resistance strategies. As the main product of… More >

Abstract
Millets hold an immense assurance for food safety and nourishment amid ever-rising agricultural expenses and climate alterations. They are healthful, have supplementary wellbeing profit and need remarkably fewer effort overheads for crop growing. These characters draw attention to millets as a plant of preference for the humankind in the course of emergent alarm about environmental changes. Millets have the prospect to provide biomass and thus bioenergy, reduced carbon emission, carbon footprint and sustainable modern agriculture. As the rate of expansion in budding countries is increasing day by day, the scarcity of energy is a big panic and there is a… More >

Abstract Tea (Camellia sinensis [L.] O. Kuntze.) is an important cash crop, which mainly uses tender shoots and young leaves for manufacturing. Due to the marketing characteristic that earlier made tea has higher price, the time of the breaking of winter dormancy buds in spring is extremely important in tea industry. Strigolactones are a group of carotenoids-derived metabolites which regulates bud outgrowth, shoot branching, tiller angle and environmental stress responses. The role of strigolactones in tea plant was briefly summarized in the current review, with an emphasis of the association of strigolactones on bud ecodormancy and shoot branching. The involvement of… More >

Abstract Most damaging plant diseases have been caused by viruses in the entire world. In tropical and subtropical areas, the damage caused by plant virus leads to great economic and agricultural losses. Single stranded DNA viruses (geminiviruses) are the most perilous pathogens which are responsible for major diseases in agronomic and horticultural crops. Significantly begomoviruses and mastreviruses are the biggest genus of plant infecting viruses, transmitted though Bemisia tabaci and members of Cicadellidae respectively. Plants possesses some naturally existing chemicals term as phyto-chemicals which perform important functions in the plant. Some antioxidant enzymes are used by plants for self-defense upon foreign… More >

Abstract Polyembryony in maize (PEm) contributes to improving the nutritional properties of the grain, as well as an increase in yield, since it generates multiple plants per seed, opening the possibility of developing new varieties. However, it is unknown whether polyembryony in maize is the product of chromosomal abnormalities. Based on the above, in this research a cytogenetic study was proposed to verify if chromosomal abnormalities are related to the maize polyembryony. For a meiotic study, maize genotypes with variable proportions of polyembryony (PEm), from the UA-IMM-BAP population and non-PEm (monoembryonic) maize were used, while for a mitosis analysis, 30 families… More >

Abstract The chloroplast NAD(P)H dehydrogenase (NDH) complex, as one of
the most important photosynthesis protein complexes in thylakoid membrane, is
involved in photosystem I (PSI) cyclic electron transport (CEF). Under abiotic
environmental stress, the photosynthetic apparatus is susceptible to the damage
caused by the strong light illumination. However, the enhancement of NDHdependent CEF could facilitate the alleviation of the damage to the photosynthetic
apparatus. The NdhB subunit encoded by chloroplast genome is one of most
important subunits of NDH complex and consists of 510 amino acids. Here,
according to cloning ndhB from Melrose (cultivated soybean), ACC547 (wild
salt-tolerant soybean), S113-6 and… More >

Abstract Plant architecture is a vital agronomic trait to control yield in rice (Oryza sativa L.). A dwarf and small seed 1 (dss1) mutant were obtained from the ethyl methanesulfonate (EMS) mutagenized progeny of a Guizhou glutinous landrace cultivar, Lipingzabianhe. The dss1 mutant displayed phenotypes similar to those of brassinosteroid (BR) deficient mutants, such as dwarfing, dark green and rugose erect leaves, small seeds, and loner neck internode panicles with primary branching. In our previous study, the underlying DSS1 gene was isolated, a novel allele of OsDWARF (OsBR6ox) that encodes a cytochrome P450 protein involved in the BR biosynthetic pathway by… More >

Abstract Fiber length is a critical trait that principally determines cotton spinning
quality, while Upland cotton as the most widely cultivated Gossypium species
around the world subjects to the relatively ordinary fiber performance. Chromosome segment substitution lines (CSSLs) have been introduced in cotton breeding
to take full advantages of superior fiber quality and high yield from Sea Island and
Upland cotton, respectively, which serve as ideal materials for elucidating the
genetic mechanism of complex quantitative traits. Here, three CSSLs derived
from CCRI45 (G. hirsutum) × Hai1 (G. barbadense), two superior (MBI7561 and
MBI7747) and one (MBI7285) with ordinary fiber-quality, were subjected… More >
