Significance The valley of Tehuacán in Mexico is an important center early Mesoamerican agriculture. To characterize the genetic constitution earliest phase maize cultivation, we reexamined San Marcos cave and sequenced DNA from three newly discovered samples dating at a similar age 5,000 y B.P. genomes these reveal unforeseen levels diversity as compared with modern maize, indicating that effects domestication were not yet complete. We find their was influenced by inbreeding, suggesting...
Summary Thlaspi arvense (field pennycress) is being domesticated as a winter annual oilseed crop capable of improving ecosystems and intensifying agricultural productivity without increasing land use. It selfing diploid with short life cycle amenable to genetic manipulations, making it an accessible field‐based model species for genetics epigenetics. The availability high‐quality reference genome vital understanding pennycress physiology clarifying its evolutionary history within the...
Natural plant populations often harbour substantial heritable variation in DNA methylation. However, a thorough understanding of the genetic and environmental drivers this epigenetic requires large-scale high-resolution data, which currently exist only for few model species. Here, we studied 207 lines annual weed Thlaspi arvense (field pennycress), collected across large latitudinal gradient Europe propagated common environment. By screening sequence methylation using whole-genome...
Two grain amaranth transcription factor (TF) genes were overexpressed in Arabidopsis plants. The first, coding for a group VII ethylene response TF (i.e., AhERF-VII) conferred tolerance to water-deficit stress (WS) transgenic without affecting vegetative or reproductive growth. A significantly lower water-loss rate detached leaves coupled reduced stomatal opening of plants subjected WS was associated with this trait. also an increased antioxidant enzyme activity and the accumulation putative...
Small RNA (sRNA)-mediated gene silencing represents a conserved regulatory mechanism controlling wide diversity of developmental processes through interactions sRNAs with proteins the ARGONAUTE (AGO) family. On basis large phylogenetic analysis that includes 206 AGO genes belonging to 23 plant species, group into four clades corresponding distribution proposed for ten family members Arabidopsis thaliana. A primary protein sequences resulted in 50 amino acids (blocks) across their linear...
The life cycle of flowering plants alternates between a predominant sporophytic (diploid) and an ephemeral gametophytic (haploid) generation that only occurs in reproductive organs. In Arabidopsis thaliana, the female gametophyte is deeply embedded within ovule, complicating study genetic molecular interactions involved to transition. Massively parallel signature sequencing (MPSS) was used conduct quantitative large-scale transcriptional analysis fully differentiated ovule prior...
To investigate the genetic and molecular regulation that female gametophyte could exert over neighboring sporophytic regions of ovule, we performed a quantitative comparison global expression in wild-type nozzle/sporocyteless (spl) ovules Arabidopsis thaliana (Arabidopsis), using Massively Parallel Signature Sequencing (MPSS). This resulted 1517 genes showing at least 3-fold increased lacking gametophyte, including those encoding 89 transcription factors, 50 kinases, 25 proteins containing...
