Abstract:
... Seed germination is the most critical phase in plant life cycle and sensitive to saline-alkaline stress. However, few studies have investigated the mechanisms by which rice seeds respond and tolerate to saline-alkaline stress. We explored physiological and molecular mechanisms underlying tolerance to saline-alkaline stress during seed germination using two rice genotypes (Dongdao-4 and Jigeng-88) ...

Abstract:
... A key component of seed germination is the interplay of mechanical forces governing embryo growth and the surrounding restraining endosperm tissue. Endosperm cell separation is therefore thought to play a critical role in the control of this developmental transition. Here we demonstrate that in Arabidopsis thaliana seeds, endosperm cell expansion is a key component of germination. Endosperm cells ...

Abstract:
... Melatonin is a pleiotropic molecule with many diverse actions in plants. It is considered primarily an antioxidant with important actions in the control of reactive oxygen and nitrogen species (ROS and RNS), among other free radicals, and harmful oxidative molecules present in plant cells. In addition, plant melatonin is involved in multiple physiological actions, such as growth, rooting, seed ger ...

Abstract:
... BACKGROUND: Efficient seed germination is a crucial task at the beginning of crop cultivation. Although boundaries of environmental parameters that should be maintained are well studied, fine-tuning can significantly improve the efficiency, which is infeasible to be done manually due to the high dimensionality of the parameter space. RESULTS: Traditionally seed germination is performed in climatic ...

We investigated whether fungal associations occur in the seeds and seedling roots of two epiphytic Aechmea species, and we explored whether substrate and fungal associations contribute to seed germination, and seedling survival and performance after the first month of growth. We found a total of 21 gen ...

Abstract:
... DELLA proteins are a group of plant specific GRAS proteins of transcriptional regulators that have a key role in gibberellin (GA) signaling. In Arabidopsis, the DELLA family is formed by five members. The complexity of this gene family raises the question on whether single DELLA proteins have specific or overlapping functions in the control of several GA-dependent developmental processes.

Abstract:
... Sexual plant reproduction is a strategy that allows plant populations to increase genetic variability, and consequently to be more efficient in adapting to new environments and to overcome stress conditions. Here, we focus on the reproductive mode of Phragmites australis, an important sub-cosmopolite species that can spread both by clonal propagation and sexual reproduction. In Europe, P. australi ...

Abstract:
... Plants exhibit helical growth movements known as circumnutation in growing organs. Some studies indicate that circumnutation involves the gravitropic response, but this notion is a matter of debate. Here, using the agravitropic rice mutant lazy1 and space‐grown rice seedlings, we found that circumnutation was reduced or lost during agravitropic growth in coleoptiles. Coleoptiles of wild‐type rice ...
